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.

Computer modeling suggests that – billions of years ago, when our solar system was young – a star swept near, stealing some of our sun’s material and creating the odd orbits of Kuiper Belt objects.

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.

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.

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 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.

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.

In space, dust comes from comets and exploding stars. It can form planetary rings, drive global weather patterns and even form the seeds of new planets.

Asteroid on a collision course with Earth? These astronomers will likely see it first. NASA’s Center for Near-Earth Object Studies – now entering its 3rd decade – makes over 90 percent of near-Earth asteroid and comet discoveries. Here’s how and why they do their work.

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.

“Mars wouldn’t be nearly this dusty if it wasn’t for this one enormous deposit that is gradually eroding over time and polluting the planet, essentially.”

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.

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