The strange case of 2 missing giant exomoons (and maybe others)

Astronomers in Germany say that 2 possible giant exomoons probably don't actually exist. That's disappointing, but there are still some other candidates.

Watery plumes on Enceladus could hold signs of life

Do the plumes on Enceladus contain evidence of life from the moon's ocean? A new study shows that amino acids could survive and be detectable by spacecraft.

Does Chiron have rings? Or ring mimics?

A new study suggests that the possible rings around the centaur Chiron in the outer solar system are instead "evolving material" that mimics rings.

Can haze on water worlds aid in the search for life?

Researchers at Johns Hopkins are simulating haze on water worlds. The haze muddles observations but can also help determine if an exoplanet is habitable.

Rocky exoplanets can form in the most extreme environments

NASA's James Webb Space Telescope has found molecular building blocks of rocky exoplanets in a region previously thought to be too extreme and hostile.

1st planet-forming disk found in another galaxy

For the first time, astronomers have discovered a planet-forming disk around a young star in another galaxy outside our own Milky Way galaxy.

What the Chinese Zhurong rover found beneath Mars’ surface

China's Zhurong rover has found polygonal wedges below the surface in Utopia Planitia on Mars. Freeze-thaw cycles of water and ice likely created the polygons.

Space Force to track ‘abnormal objects of unknown origin’

The U.S. Space Force wants to track objects near Earth that exhibit 'abnormal observables' and are of 'unknown origin.' Could there be a connection to UAP?

Nearby exoplanet is Earth twin, but hot as a pizza oven

Astronomers using the Hubble Space Telescope measured the exact diameter of a nearby Earth-sized exoplanet. The sizzling world is too hot for life, however.

Shrinking exoplanets? Here’s how it happens

Scientists say they may have solved the mystery of shrinking exoplanets. Radiation from the cores of less massive sub-Neptunes pushes away their atmospheres.
