Exoplanets with and without a magnetic field are predicted to form, behave, and evolve very differently. In order to understand the exoplanet population, and to make progress understanding habitability, astronomers need to understand and constrain exoplanets' magnetic fields. Detecting them may best be done from the Moon.

Physicists from the University of Copenhagen have begun using the gigantic magnetic fields of galaxy clusters to observe distant black holes in their search for an elusive particle that has stumped scientists for decades.

We already know a decent amount about how planets form, but moon formation is another process entirely, and one we’re not as familiar with. Scientists think they understand how the most important Moon in our solar system (our own) formed, but its violent birth is not the norm, and can’t explain larger moon systems like the Galilean moons around Jupiter. A new book chapter (which was also released as a pre-print paper) from Yuhito Shibaike and Yann Alibert from the University of Bern discusses the differing ideas surrounding the formation of large moon systems, especially the Galileans, and how we might someday be able to differentiate them.

The Universe's early galaxies were engulfed in halos of high-energy cosmic rays. It's likely because they had tangled and turbulent magnetic fields. These fields accelerate cosmic rays to higher energies.

China took a step closer to the Moon, with the first short test for their crewed lunar lander. The test was completed on Wednesday, August 6th at a facility in China’s northern Hebei Province, and lasted just under 30 seconds. The tethered test successfully demonstrated the integration and performance of key systems, simulating descent, guidance, control and engine shutdown. This marks the first test for a China’s Manned (crewed) Space Agency (CMSA’s) human-rated lander.

Taking a walk is great for inspiration. There have been numerous studies about how people think more clearly on walks, and how new ideas come to them more frequently while doing so. That’s part of the reason some of the most famous minds in history included a daily walk in their schedule. Just such an inspiration must have happened recently to Nicholas Heinz, a scientist at NASA’s Jet Propulsion Laboratory (JPL) in California. On a hike in Arizona he found a rock that could be used as an analog of a unique one found by the Perseverance rover on Mars - and decided to take it back to his lab to study it.x

Climate change isn't just transforming weather on Earth's surface, it’s also fundamentally altering how space weather affects the thousands of satellites orbiting our planet. New research reveals that rising carbon dioxide levels will dramatically change how geomagnetic storms impact the upper atmosphere, creating both opportunities and challenges for the satellite industry in the decades ahead.

Space is getting dangerously crowded. More than 50,000 pieces of debris larger than 10 centimetres are currently hurtling around Earth at breakneck speeds, turning Earth orbits into veritable minefields. Dead satellites, rocket fragments, and collision debris pose such a serious threat that the International Space Station regularly performs emergency manoeuvres to dodge potential impacts. Now, an international team of researchers thinks they've found an elegant solution to this growing crisis and it's inspired by a humble house gecko's amazing ability to walk on walls.

What if the universe began with a fireworks show? A new theory suggests that supermassive black holes, the mysterious giants found at the heart of galaxies, were born from the universe's very first stars in a spectacular flash of light that ionised all of space before vanishing forever. This dramatic "Pop III.1" model could finally explain how these giant stellar remnants grew so impossibly large so quickly after the Big Bang, while potentially solving several major puzzles plaguing modern astronomy, from the Hubble Tension to the nature of Cosmic Dawn itself.

Our Moon is a seismically active world and its long history of quakes could affect the safety of permanent base structures there. That's one conclusion from a study of quakes along the Lee-Lincoln fault in the Taurus-Littrow valley where the Apollo 17 astronauts landed in 1972. “The global distribution of young thrust faults like the Lee-Lincoln fault, their potential to be still active and the potential to form new thrust faults from ongoing contraction should be considered when planning the location and assessing stability of permanent outposts on the Moon,” said Smithsonian senior scientist emeritus Thomas R. Watters, lead author of the paper.

Supercomputer simulations are helping scientists sharpen their understanding of the environment beyond a black hole’s "shadow," material just outside its event horizon.

The exoplanet TRAPPIST-1 d intrigues astronomers looking for possibly habitable worlds beyond our Solar System because it is similar in size to Earth, rocky, and resides in an area around its star where liquid water on its surface is theoretically possible. But according to a new study using data from the NASA/ESA/CSA James Webb Space Telescope, it does not have an Earth-like atmosphere.

Deep in the darkness, tiny red specks of light have been driving astronomers to distraction. These mysterious "little red dots" discovered by the James Webb Space Telescope shouldn't exist, they’re impossibly compact yet blazingly bright, defying our understanding of how galaxies form. Now, Harvard researchers believe they've solved this billion year old puzzle with a theory involving the universe's rarest structures; dark matter halos.

Mars still holds the promise of being one of the first places in the solar system humanity will colonize. However, if there was evolutionarily distinct, extant life on the planet, it might sway the heart of even the most ardent Mars colonization fans. So astrobiologists are in a race against time to try to determine whether or not such life exists, before the entire planet becomes an analogue of the Earth’s biosphere, if only unintentionally, and only a shadow of the ones that exists here. A new paper from the Christopher Temby and Jan Spacek of the Agnostic Life Finder (ALF) team discusses one of the most promising ways to prove definitively that life exists on the Red Planet - finding polyelectrolyte polymers - in other words, DNA.

When black holes are disrupted by things like infalling matter or gravitational waves, they vibrate like a bell struck with a clapper. The vibrations decay over time as the black hole returns to an equilibrium state. Astrophysicists can measure these vibrations to learn more about the black hole.

New research shows how the 'dancing' behaviour of dwarf satellite galaxies can predict mergers between their hosts. A distant pair of galaxies is undergoing the same type of merger that Milky Way/Andromeda will undergo. Can the behaviour of their dwarf satellites tell astronomers what will happen when the MW and Andromeda merge?

A stunning new image of a cosmic jet has helped astronomers unlock the mystery behind the unusually bright emission of high-energy gamma rays and neutrinos from a peculiar celestial object. The source is a blazar—a type of active galaxy powered by a supermassive black hole devouring matter at the heart of a galaxy. They have captured what looks like the mythical "Eye of Sauron" in the distant universe and may have just solved a decade-long cosmic puzzle.

Any material used as a light sail is bound by very restrictive physical requirements. It has to be extremely light , can’t melt from the energy applied to it, and must bend, but not break, from that pressure. Various research groups around the world have been working on materials they believe will meet those requirements, and a new paper from researchers at the University of Pennsylvania describes experimental testing of what they believe to be the most functional light sail material yet developed.

A supermassive black hole in the act of awakening from slumber haas been detected by a team of astronomers. Using powerful radio telescopes, they observed this sleeping giant as it began to stir for the first time, offering an unprecedented look at how these stellar monsters come to life. Located 6 billion light years away, this giant has been dormant but suddenly roared to life just 1,000 years ago, revealing secrets about how the universe's most powerful forces shape entire galaxies.

Space is getting dangerously crowded but a new automated system could be the key to preventing catastrophic collisions that threaten our satellites and astronauts. The European Space Agency has developed CREAM (Collision Risk Estimation and Automated Mitigation), a revolutionary technology that aims to transform how we manage traffic in Earth orbit and keep space safe for future generations.
