A team of NASA scientists proposed a new initiative at the 56th Lunar and Planetary Science Conference (2025 LPSC). Known as the Commercial Hall Propulsion for Mars Payload Services (CHAMPS), the

How can you fairly compare one telescope to another? It’s all in the (angular) resolution.

Scientists have known for a while that Mars currently lacks a magnetic field, and many blame that for its paltry atmosphere - with no protective shield around the planet, the solar wind was able to strip away much of the gaseous atmosphere over the course of billions of years. But, evidence has been mounting that Mars once had a magnetic field. Results from Insight, one of the Red Planet's landers, lend credence to that idea, but they also point to a strange feature - the magnetic field seemed to cover only the southern hemisphere, but not the north. A team from the University of Texas Institute for Geophysics thinks they might know why - in a recent paper, they described how a fully liquid core in Mars could create a lopsided magnetic field like the one seen in Insight’s data.

You never know when a central supermassive black hole is going to power up and start gobbling matter. Contrary to the popular view that these monsters are constantly devouring nearby stars and gas clouds, it turns out they spend part of their existence dormant and inactive. New observations from the European Space Agency's XMM-Newton spacecraft opened a window on the "turn on event" for one of these monsters in a distant galaxy.

In a recent paper, a team of researchers indicated that photosynthetic bacteria could exist just beneath the snow and ice around Mars' mid-latitudes. If true, this could be the most easily accessible place to look for present-day life on Mars.

The solar system is currently embedded deep within the Local Bubble, a region of relatively low density stretching for a thousand light-years across. It was carved millions of years ago by a chain of supernova explosions. And the evidence for it is right under our feet.

According to a recent study by the non-profit Explore Titan, a nuclear-fission propulsion spacecraft could enable the first crewed mission to Titan, Saturn's largest moon.

In our neighborhood of the Milky Way, we see a region surrounding the solar system that is far less dense than average. But that space, that cavity, is a very irregular, elongated shape. What little material is left inside of this cavity is insanely hot, as it has a temperature of around a million Kelvin.

Astrobiologists are dying to send another mission to study Enceladus, the icy moon that orbits Saturn and has active plumes emanating from its surface, A team from NASA's Jet Propulsion Laboratory (JPL) proposes an Enceladus Orbitlander that would conduct in-situ measurements of Enceladus' plumes, which could confirm the presence of organics and maybe even life in its interior.

What can Helium-3 (3He) being discharged from the Sun teach us about 3He creation and the Sun’s activity? This is what a recent study published in The Astrophysical Journal hopes to address as an international team of researchers investigated 3He-rich solar energetic particles (SEPs) emitted by the Sun in late 2023. This study has the potential to help astronomers better understand how solar activity could contribute to the production of 3He, the latter of which remains one of the most desired substances due to its potential for nuclear fusion technology on Earth.
