ESA's New Mission Can See a Solar Eclipse Every Day

June 20, 2025

Solar eclipses are beautiful, but they're a valuable chance to study the Sun's atmosphere as its surface is blocked by the Moon. Now, ESA can generate artificial solar eclipses from space with the Proba-3 mission. The two satellites fly in formation 150 meters apart. One spacecraft occults the Sun, while the other observes the faint solar corona. They can produce a new 6-hour eclipse every 19.6-hour orbit around the Earth. Solar eclipses on demand.
Fast Radio Bursts are Helping to Locate the Universe's Missing Matter

June 19, 2025

You're probably aware that most of the matter of the Universe is "dark matter," and astronomers still don't know what it is. But 75% of the regular matter in the Universe is also hidden, located in the thin gas between galaxies. Probing this gas is difficult, but astronomers have used a new technique, analyzing the light from fast radio bursts as they pass through billions of light-years of gas. Longer, redder wavelengths are slowed down compared to shorter, bluer wavelengths, allowing the hidden material to be weighed.
Spaceflight Could Be Bad For Your Teeth

June 19, 2025

Great, another potential long-term risk of spaceflight. Researchers have studied the effects of simulated microgravity on mice and found that it could lead to periodontitis, where the gums become inflamed and the bones supporting teeth start to break down. This was compared to mice who experienced normal gravity. This could be limited to just the teeth or a larger indicator of inflammation in the body caused by weightlessness, which could have other health impacts.
NASA's PUNCH Mission Captured Images of a Huge Solar Eruption

June 15, 2025

During its commissioning phase, NASA's [*Polarimeter to Unify the Corona and Heliosphere*](https://science.nasa.gov/blogs/punch/) (PUNCH) mission captured high-resolution images of a [Coronal Mass Ejection](https://www.swpc.noaa.gov/phenomena/coronal-mass-ejections) (CME) in greater detail than was previously possible.
Telescopes in Chile Capture Images of the Earliest Galaxies in the Universe

June 14, 2025

An international team of astronomers using the [*Cosmology Large Angular Scale Surveyor*](https://sites.krieger.jhu.edu/class/) (CLASS) [reported the first-ever measurement](https://hub.jhu.edu/2025/06/11/telescopes-look-at-cosmic-dawn/) announced the first-ever detection of radiation from the cosmic microwave background (CMB) interacting with the first stars in the Universe.
We Can Use Black Holes Particle Accelerators

June 06, 2025

The Large Hadron Collider has changed particle physics, and now scientists are dreaming up even bigger supercolliders. But humanity can't match the raw particle-colliding power of a supermassive black hole. In a new paper, researchers describe how supermassive black holes create a dense environment where particles are spinning at relativistic speeds and crashing into each other, releasing other particles that could be detectable on Earth.
NASA's FY 2026 Budget Request has been Released

June 05, 2025

It's official. NASA's Fiscal Year 2026 Discretionary Budget Request (FY 2026) has been released, and the news is decidedly mixed. In a previous article, we examined the FY 2026 Budget Request (released on May 2nd) and its recommendations for the coming year. With the release of the FY 2026 Budget, what was previewed and the anxiety it caused for many have been confirmed. While the Budget bolsters funding for NASA's exploration programs for the Moon and Mars, it also contains deep cuts to many other programs and the cancellation of key elements in NASA's Moon to Mars architecture.
Missions to Mars with the Starship Could Only Take Three Months

June 02, 2025

In a recent paper, UCSB physicist Jack Kingdon identified a trajectory for a rapid transit (90 days) to Mars using SpaceX's Starship. This proposal offers an alternative to mission architectures that rely on nuclear propulsion to reduce transit times.

Clouds Could Enhance the Search for Life on Exoplanets

May 28, 2025

A team of geophysicists from the University of Chicago showed how clouds on exoplanets could enhance the search for biosignatures. Their findings could have significant implications for the Habitable Worlds Observatory (HWO) and other next-generation telescopes that will study exoplanets via direct imaging.
Passing Stars Could Have a Significant Impact on the Future of our Solar System

May 28, 2025

Studies of the Solar System's dynamics generally treat it in isolation and do not consider the influence a passing star could have on the orbits of the planets over time. According to a recent study by a team of astronomers, stars passing close to the Solar System could result in the loss of planets over the next 5 billion years.
Astronomers Conduct a Preliminary Search for Exoplanets Around Alpha Centauri

May 23, 2025

An international team of researchers has announced the preliminary findings of Webb's observations of the Alpha Centauri system. According to their analysis, Webb could detect a Jupiter-sized planet and a very bright zodiacal dust disk around Alpha Cen A. More information will be released soon!
New Study Suggests that Jupiter was Once Twice as Big as it is Today

May 20, 2025

Jupiter and its powerful gravity have played a major role in sculpting the Solar System. A new study provides a glimpse into Jupiter's primordial state, which could have implications for our understanding of how the Solar System evolved.
Meteor Impacts on Mars Can Excavate its Secrets

May 18, 2025

Spacecraft orbiting Mars can reveal small features on the planet's surface, but there are only so many things you can see from above. When a meteor strikes the surface of Mars, it can excavate sub-surface material, allowing scientists to study what lies beneath. Researchers have simulated various impacts on Mars, changing the sub-surface material from bedrock to water-ice glaciers, and then calculated what should be visible after an impact, enabling new science.
Astronauts Could See Auroras on Mars with their Eyes

May 17, 2025

Earth's magnetosphere channels particles from solar storms into stunning auroras. Mars lacks a planet-wide magnetic field and has patchy auroras barely detectable with instruments. Or so we thought. New images captured by NASA's Perseverance Rover with its Mastcam-Z instrument show green auroras in visible light. When humans finally walk on Mars and look to the skies, they could possibly see faint auroras there, too.
A Lunar Telescope that Could Explore the Cosmic Dark Ages

May 16, 2025

In a recent paper, an international team proposed an ultra-long wavelength radio interferometer that could examine the Cosmic Dark Ages and Cosmic Dawn. Known as the Dark Ages Explorer (DEX), this telescope could provide fresh insights into how and when the first stars and galaxies formed.
The Fastest Spinning Asteroids are Most Likely to Have Moons

May 12, 2025

When NASA's Galileo spacecraft flew past asteroid Ida, it discovered a second, smaller asteroid in orbit: Dactyl. This was the first confirmed discovery of an asteroid with a moon, but now we know of many, including 13 asteroids larger than 100 km with satellites. Researchers have found that the mostly rapidly spinning asteroids are more likely to have moons; a large impact both spins up the asteroid and creates the debris that remains in orbit.
Not Saying it's Aliens: SETI Survey Reveals Unexplained Pulses From Distant Stars

May 12, 2025

Veteran NASA scientist Richard H. Stanton describes the results of a multi-year survey of more than 1300 Sun-like stars for optical SETI signals. This survey revealed two fast identical pulses from a Sun-like star about 100 light-years from Earth, that match similar pulses from a different star observed four years ago.
Perseverance Happened to Land Right Beside a Composite Volcano

May 09, 2025

NASA's Perseverance Rover landed in Jezero Crater, an ancient impact crater that was probably filled with water for a long time. During its exploration, the rover has discovered volcanic rocks on the crater floor, but the original source hasn't been found. Now, a team of researchers thinks there's a composite volcano right on the edge of Jezero Crater. They identify a conical-shaped structure that rises about 2 km above the surrounding plains.
ispace's RESILIENCE Enters Lunar Orbit. It'll Try to Land in Early June

May 07, 2025

On May 7th, the Japanese space exploration company ispace announced that its HAKUTO-R RESILIENCE lander entered lunar orbit after completing a 9-minute thruster burn. It's now in a stable lunar orbit, and operators will spend the next month testing and preparing for its landing attempt on June 5. This is the company's second attempt at landing on the Moon, after the first attempt crashed in 2023. It's carrying a micro-rover and several science experiments.
