Why so few galaxies in this distant region of space?

Galaxies are not evenly distributed throughout the universe, but even so, this large region of space has far fewer galaxies than astronomers expected to find.

Astronomers find weird rogue world with wild auroras

This free-floating rogue planet – untethered to any star – has a magnetic field millions of times more powerful than Earth’s and auroras much more brilliant than our world’s northern lights.

Jupiter’s moon Ganymede has powerful chorus waves

Chorus waves can be converted to sound. The ones around Earth sound like singing or chirping birds. Jupiter has stronger chorus waves, and now its large moon – Ganymede – has been found to have chorus waves a million times stronger than Jupiter’s.

Astronomers discover new, enigmatic fast radio burst

Fast radio bursts – aka FRBs – are brief, powerful, puzzling bursts of radio waves from deep space. Now astronomers have detected a new and even more unusual type of FRB.

Plate tectonics not necessary for alien life?

New research indicates that plate tectonics may not be necessary for life to evolve after all, increasing the chances that more exoplanets could support life of some kind.

Scientists identify best exoplanets for Earth-like life

Scientists have now identified some exoplanets that might have suitable temperatures for liquid water and enough UV light for the chemistry thought to have led to life on Earth.

Where to look for life on Titan

Saturn’s moon Titan has lakes and seas, filled with liquid ethane and methane. But they might not be the best places to look for life, according to new research.

An easier way to search for life on Europa

Jupiter’s moon Europa is a promising place to search for evidence of alien life. New research provides insights on what might be the best – and easiest – way to search.

Subsurface lake discovered on Mars?

ESA’s Mars Express spacecraft has discovered the 1st evidence for a subsurface liquid lake on Mars. If it exists, this lake is likely salty and cold, but possibly habitable for some microorganisms.

The case for a habitable moon

Not now, but billions of years ago, microbes might have thrived in water pools on the moon until its surface became dead and dry.
