A video that appeared on CGTN's Hot Take details four missions that China will be sending to space in the coming years, including a survey telescope that will search for Earth 2.0.

A powerful geomagnetic superstorm is a once a generation event, happening once every 20-25 years. Such an event transpired on the night of May 10/11, 2024, when an intense solar storm slammed into the Earth’s protective magnetic sheath. Now, a recent study shows just how intrusive that storm was, and how long it took for the Earth’s plasma layer took to recover.

Observations with the SPHERE instrument on the European Southern Observatory's VLT revealed the presence of debris rings similar to structures in our Solar System. SPHERE found rings similar to the Kuiper Belt and the Main Asteroid Belt. Though individual asteroids and comets can't be imaged, these debris rings infer that other solar systems have architectures similar to ours.

It’s been over two years since the samples from Bennu gathered by OSIRIS-REx were returned to Earth. But there’s still plenty of novel science coming out of that 121.6 g of material. Three new papers were released recently that describe different aspects of that sample. One in particular, from Yoshihiro Furukawa of Tohoku University in Japan and their co-authors, has already attracted plenty of attention, including from US Senator (and former astronaut) Mark Kelly. It shows that all of the building blocks for early life were available on the asteroid - raising the chances that planets throughout the galaxy could be seeded with the abiotic precursors for life.

What can mapped drainage systems on Mars teach scientists about the Red Planet’s watery past? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of scientists from the University of Texas at Austin (UT Austin) conducted a first-time mapping study involving Martian river basins. This study has the potential to not only gain insight into ancient Mars and how much water existed there long ago but also develop new methods for mapping ancient river basins on Mars and potentially other worlds.

Scientists have launched COLIS, a special laboratory aboard the International Space Station designed to study how everyday materials like sunscreens, mayonnaise, and medications behave in near zero gravity. Researchers discovered that gravity influences the long term stability of soft matter far more dramatically than previously understood, affecting how these materials age and restructure at the molecular level. This research could fundamentally improve how we design everything from controlled release drugs to self assembling materials, demonstrating that understanding materials in space offers unexpected benefits for life on Earth.

On a summer day in 709 BCE, scribes at the Lu Duchy Court in ancient China looked up to witness something extraordinary. The Sun vanished completely from the sky, and in its place hung a ghostly halo. They recorded the event carefully, noting that during totality the eclipsed Sun appeared "completely yellow above and below." Nearly three millennia later, that ancient observation has helped modern scientists measure how fast Earth was spinning and understand what our Sun was doing at a time when Homer was composing poetry.

An international team has made a significant breakthrough in understanding the tectonic evolution of terrestrial planets. Using advanced numerical models, the team systematically classified for the first time six distinct planetary tectonic regimes. Their work provides a unified theory on the geological evolution of both Earth and Venus.

Intermediate mass stars experience periods of rapid growth in their late stages of formation. The growing young star emits more radiation that encourages greater accretion. Rather than depleting their protoplanetary disks and preventing gas giants from forming, the opposite is true.

In a recent paper, a team of SETI and astrobiology specialists examines four controversial claims about the existence of extraterrestrial life. From these, they present recommendations for scientists and science communicators when addressing future claims of discovery.

Searching for technosignatures - signs of technology on a planet that we can see from afr - remains a difficult task. There are so many different factors to consider, and we only have the technological capabilities to detect a relatively small collection of them. A new paper, available in pre-print on arXiv but also accepted for publication into The Astrophysical Journal Letters, from Jacob Haqq-Misra of the Blue Marble Space Institute of Science and his co-authors explores some of those capabilities by using a framework they developed known as Project Janus that estimates what technology will look like on Earth 1,000 years from now in the hopes that we can test whether or not we can detect it on another planet.

What can an exoplanet leaking helium teach astronomers about the formation and evolution of exoplanet atmospheres? This is what a recent study published in Nature Astronomy hopes to address as an international team of scientists investigated atmospheric escape on a puffy exoplanet. This study has the potential to help scientists better understand the formation and evolution of gas giant planets, specifically with many gas giant planets observed orbiting extremely close to their stars.

arXiv:2512.00492v1 Announce Type: new Abstract: We describe how the ESA Comet Interceptor mission, which is due to launch in 2028/29 to a yet-to-be-discovered target, can provide a conceptual basis for a future mission to visit an Interstellar Object. Comet Interceptor will wait in space until a suitable long period comet is discovered, allowing rapid response to perform a fast flyby of an object that will be in the inner Solar System for only a few years; an enhanced version of this concept ...

The JWST has made a name for itself by discovering mature galaxies in the Universe's early times. This time, a pair of Indian astronomers working with the JWST found a fully-formed spiral galaxy much like the Milky Way only 1.5 billion years after the Big Bang. The discovery, and others like it, are forcing scientists to reconsider their understanding of the cosmic timeline.

We've long known that we move through the Universe relative to the cosmic microwave background, but a new study of radio galaxies finds an even faster result, which could contradict the standard model of cosmology.

The European Space Agency has release its ESA/Webb Picture of the Month and it features a pair of dwarf galaxies engaged in a tentative dance, like nervous partners at a social. The pair are a staggering 24 million light-years away. But even at that great distance, the pair of galaxies is the closest-known interacting pair of dwarfs, other than the Milky Way's Magellanic Clouds, where both the stellar populations and the gas bridge linking the galaxies have been observed.

There’s been a lot of speculation recently about interstellar visitor 3I/ATLAS - much of which is probably caused by low quality data given that we have to observe it from either Earth, or in some case Mars. In either case it’s much further away that what would be the ideal. But that might not be the case for a future interstellar object. The European Space Agency (ESA) is planning a mission that could potentially visit a new interstellar visitor, or a comet that is making its first pass into the inner solar system. But, given the constraints of the mission, any such potential target object would have to meet a string of conditions. A new paper by lead Professor Colin Snodgrass of the University of Edinburgh of his colleagues, discusses what those conditions are, and assesses the likelihood that we’ll find a good candidate within a reasonable time of the mission's launch.

To celebrate 25 years since the completion of the International Gemini Observatory, students in Chile voted for the Gemini South telescope to image NGC 6302 — a billowing planetary nebula that resembles a cosmic butterfly. The International Gemini Observatory is partly funded by the U.S. National Science Foundation (NSF) and operated by NSF NOIRLab.

Why is the Universe filled with matter? Why isn't it an equal amount of matter and antimatter? We still don't know the answer, but a new approach looks at the symmetries of extended models of particle physics and finds a possible path forward. It's a knotty problem that may just have a knotty solution.

Remember back in 2018 when there was a discovery of a briny “lake” underground near the Martian south pole? Pepperidge Farm probably does, and anyone that works there that’s interested in space exploration will be disappointed to hear that, whatever might be causing the radar signal that finding was based on, it’s most likely not a lake. At least according to new data collected by the Mars Reconnaissance Orbiter (MRO) and published recently in Geophysical Research Letters by lead author Gareth Morgan of the Planetary Science Institute and his colleagues.

The complex molecules required for life on Earth might never have formed if it wasn’t for cosmic dust.

There is a period in the Universe known as the cosmic dark ages. It lies between the recombination of the first atoms and the ignition of the first stars, when the Universe was thought to be cold and dark. Now astronomers have looked at the faint glow of atomic hydrogen to find that while the Universe was dark, it wasn't quite as cold as we thought.

Searching for exomoons - moons the orbit around another planet - was one of the most exciting capabilities expected of the James Webb Space Telescope (JWST) when it launched in late 2021. So, after four years of operation, why hasn’t it found one yet? Turns out it’s really, really hard to find a moon around a planet light-years away. A new paper available in pre-print on arXiv from David Kipping of Columbia University (and Cool Worlds YouTube Channel fame) shows why. They used 60 hours of time on JWST’s NIRSpec instrument and weren't able to definitively confirm the existence of a possible exomoon.

What can water in Jupiter’s atmosphere teach scientists about the planet’s composition? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of scientists investigated the distribution of water with Jupiter’s atmosphere. This study has the potential to help scientists better understand Jupiter’s atmospheric dynamics, composition, and evolutionary history.

What steps can be taken to improve and enhance the lifetime of space solar cells? This is what a recent study published in Joule hopes to address as an international team of researchers investigated new methods for improving both the lifetime and performance of space solar cells from the harshness of space weather and radiation. This study has the potential to help scientists and engineers develop new space technologies, especially as several private companies and government organizations are extending their reach into space.

Chemical rockets have taken us to the Moon and back, but traveling to the stars demands something more powerful. Space X’s Starship can lift extraordinary masses to orbit and send payloads throughout the Solar System using its chemical rockets but it cannot fly to nearby stars at thirty percent of light speed and land. For missions beyond our local region of space, we need something fundamentally more energetic than chemical combustion, and physics offers or in other words, antimatter.

Growing fresh lettuce and strawberries might sound mundane until you consider doing it on the Moon or Mars. An international team has created a roadmap for cultivating plants in space, addressing one of NASA's highest priority challenges for long duration missions. These aren't just about providing fresh food for astronauts, plants in space will recycle air and water, produce pharmaceuticals, process waste, and support mental health during years long journeys to distant worlds. With the first lunar greenhouse scheduled to operate during NASA's 2027 Artemis III mission, humanity is on the verge of becoming an agricultural species across multiple worlds.

A team of scientists have detected electric discharges on Mars for the first time, confirming a phenomenon that was theorised for decades but never directly observed until now. The Perseverance rover's microphone accidentally captured the electromagnetic and acoustic signatures of sparks generated inside Martian dust devils, similar to the static shocks you might experience touching a metal door handle. This discovery changes our understanding of Mars's atmospheric chemistry and could explain longstanding mysteries about the rapid disappearance of methane in the Martian atmosphere, while also raising important safety considerations for future human missions to the red planet.

Have scientists finally confirmed the existence of the first exomoon? This is what a recent study accepted for publication in Astronomy & Astrophysics hopes to address as a large international team of researchers investigated new methods for identifying an exomoon orbiting a gas giant exoplanet. This study has the potential to help scientists develop new methods for finding exomoons, the latter of which has yet to be confirmed.

What can an ancient supernova teach scientists about Earth and celestial objects? This is what a recently submitted study to Astronomy & Astrophysics hopes to address as a team of scientists investigated the interaction of the remnants of supernova that occurred 10-million years ago with Earth. This study has the potential to help scientists better understand how Earth is influenced by celestial objects and what this could mean for the future of life on Earth, along with potentially habitable worlds beyond Earth.

What can equatorial jet streams on gas giant planets teach scientists about gas giant planetary formation and evolution? This is what a recent study published in Science Advances hopes to address as a team of scientists investigated the mechanisms of jet streams on gas giants (Jupiter and Saturn) and ice giants (Uranus and Neptune). This study has the potential to help scientists better understand not only the formation and evolution of giant planets in our solar system, but exoplanets, too.

A crew of tiny worms will be heading on a mission to the International Space Station in 2026 that will help scientists understand how humans can travel through space safely, using a Leicester-built space pod.

How can star populations help astronomers re-evaluate the search for intelligent extraterrestrial life, also called technosignatures? This is what a recently submitted study hopes to address as a team of scientists investigated the parameters of identifying locations of technosignatures, also called extraterrestrial transmitters. This study has the potential to help astronomers constrain the criteria for finding intelligent life in both our galaxy and throughout the universe.

What can star variability—changes in a star’s brightness over time—teach astronomers about exoplanet habitability? This is what a recent study accepted to The Astronomical Journal hopes to address as a team of scientists investigated the interaction between a star’s activity and exoplanetary atmospheres. This study has the potential to help astronomers better understand how star variability plays a role in finding habitable exoplanets, specifically around stars that are different from our Sun.

Young stars buried deep in molecular clouds are bathed in ultraviolet radiation, but they shouldn't be. Protostars are too cold and dim to produce UV light themselves, yet James Webb Space Telescope observations of five stellar nurseries in Ophiuchus reveal its unmistakable signature affecting the surrounding gas. Astronomers tested the obvious explanation that nearby massive stars illuminate these birthplaces but subsequently ruled it out. The UV radiation must be coming from inside the star forming regions themselves, forcing a fundamental rethink of how stars are born.

What is the importance of studying explosive volcanism on Venus? This is what a recent study published in the Journal of Geophysical Research: Planets hopes to address as a team of scientists investigated the potential altitudes of explosive volcanism on Venus. This study has the potential to help scientists better understand the present volcanic activity on Venus, along with gaining insight about its formation and evolution and other planetary bodies throughout the solar system and beyond.

The Nancy Grace Roman Space Telescope continues its inexorable march toward launch. It recently completed another series of tests that brings it a few steps closer to a launch pad in Florida. This time, the telescope was split into two separate parts - an inner portion and an outer portion, each of which went through separate tests throughout the fall.

Research led by the RIKEN Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) in Japan has successfully performed the world’s first Milky Way simulation that accurately represents more than 100 billion individual stars over the course of 10,000 years.

New research shows how a galaxy's surroundings influence its development. Its size, shape, and growth rate are all affected. It's all based on "the finer details of the cosmic landscape."

A red giant orbiting a dormant black hole is spinning impossibly fast and contains chemistry that makes it look ancient when it's actually relatively young. By listening to faint vibrations rippling through the star, astronomers have decoded a violent secret, that this star likely collided with and absorbed another star billions of years ago, an explosive merger that left it chemically confused and rotating once every 398 days. The discovery reveals how even quiet black hole systems can have turbulent histories written in starlight.

Ninety five years after Swiss astronomer Fritz Zwicky inferred its existence from galaxies moving impossibly fast, researchers may have detected the first direct evidence of dark matter, the invisible scaffolding that holds the universe together. Using gamma ray data from NASA's Fermi Space Telescope, a Japanese physicist has identified a halo of extremely energetic photons around the Milky Way's center that matches predictions for annihilating dark matter particles. If confirmed, humanity has finally "seen" the unseeable.

On Earth, Coronal Mass Ejections (CMEs) like the one we experienced earlier this month are aesthetic, even disruptive events, sending aurora southward and interrupting radio signals. But around other stars, they could prove lethal to life. This point was driven home by a recent CME detection from an M-class red dwarf star. This marks the first detection of an energetic Type II radio burst from a nearby star.

A planet’s habitability is determined by a confluence of many factors. So far, our explorations of potentially habitable worlds beyond our solar system have focused exclusively on their position in the “Goldilocks Zone” of their solar system, where their temperature determines whether or not liquid water can exist on their surface, and, more recently, what their atmospheres are composed of. That’s in part due to the technical limitations of the instruments available to us - even the powerful James Webb Space Telescope is capable only of seeing atmospheres of very large planets nearby. But in the coming decades, we’ll get new tools, like the Habitable Worlds Observatory, that are more specifically tailored to search for those potentially habitable worlds. So what should we use them to look for? A new paper available in pre-print on arXiv by Benjamin Farcy of the University of Maryland and his colleagues, argues that we should look to how a planet formed to understand its chances of harboring life.

Since comet 3I/ATLAS, the third known interstellar object, was discovered on 1 July 2025, astronomers worldwide have worked to predict its trajectory. ESA has now improved the comet’s predicted location by a factor of 10, thanks to the innovative use of observation data from our ExoMars Trace Gas Orbiter (TGO) spacecraft orbiting Mars.

In 2028, Hong Kong will launch its first dedicated lunar orbiter not to study craters or map minerals, but to monitor something far more urgent, the constant barrage of meteoroids slamming into the Moon's surface at thousands of kilometres per hour. As China prepares to build a permanent lunar research station, understanding this relentless bombardment has become a matter of safety for future astronauts living and working on the Moon.

Beneath the frozen shells of Saturn's tiny moons, hidden oceans might occasionally boil, not from heat, but from dropping pressure as ice melts from below. This strange phenomenon could explain the bizarre geology of worlds like Miranda and Mimas, and reshape our understanding of where to search for life in the outer Solar System. A new study reveals how these distant water worlds operate under physics unlike anything on Earth.

Seven billion year old meteorites carrying DNA building blocks. Frozen water on Mars. Amino acids floating in interstellar dust clouds. After seventy years of searching, we've found the ingredients for life scattered throughout the universe but have we found life itself? A new review examines every major claim of extraterrestrial life, from ancient space rocks to UFO sightings, revealing what the evidence actually supports and where wishful thinking has filled the gaps.

The JWST has done it again. It's revealed new details hidden from lesser telescopes. The space telescope has detected four spiral dust shells around Apep, a triple star system about 15,000 light-years away.

What are the physics of life? That is more than just a philosophical question - it has practical implications for our search for life elsewhere in the galaxy. We know what Earth life looks like, on a number of levels, but finding it on another planet could require us to redefine what we even mean by life itself. A new paper from Stuart Bartlett of Cal Tech and his co-authors provides a new framework for how life could be defined that could reach beyond just what we understand from our one Pale Blue Dot.

Understanding how exactly lunar dust sticks to surfaces is going to be important once we start having a long-term sustainable presence on the Moon. Dust on the Moon is notoriously sticky and damaging to equipment, as well as being hazardous to astronaut’s health. While there has been plenty of studies into lunar dust and its implications, we still lack a model that can effectively describe the precise physical mechanisms the dust uses to adhere to surfaces. A paper released last year from Yue Feng of the Beijing Institute of Technology and their colleagues showcases a model that could be used to understand how lunar dust sticks to spacecraft - and what we can do about it.
