Giant ‘survivor’ planet found orbiting dead star

For the first time, astronomers have detected a planet orbiting a white dwarf star. If further confirmed, the discovery shows that some planets could survive the destruction of their sun-like stars, and some might even remain potentially habitable.

Wow! Jupiter might have 600 moons

Astronomers in Canada say they have found evidence for 45 new tiny moons orbiting Jupiter, and that the planet may have a staggering 600 such moons in total.

Has microbial life been found on Venus?

Is there microbial life in the atmosphere of Earth’s closest neighbor, Venus? An international team of astronomers has found tentative but highly compelling evidence.

Search for ETs among 10 million stars comes up empty

Astronomers used a radio telescope in Australia to search for artificial radio signals among 10 million stars. The search came up empty. But, they say, that’s not bad news for those hoping to find intelligent extraterrestrials.

Nearby red dwarf star not so quiet and life-friendly after all

Astronomers say the nearby red dwarf star Gliese 887 appears to have more dangerous flare activity than first believed. This could make life tough – but maybe not impossible – on its family of super-Earth planets.

Cool! Here’s how Venus would look as a water world

A new map created by a Reddit user – based on what we know about the highs and lows on Venus’ surface – shows what this neighboring, cloud-shrouded, blazing hot planet might look like with oceans. Wow!

The true polar wander of Jupiter’s moon Europa

Cracks in Europa’s surface indicate the moon’s outer ice shell has shifted by as much as 70 degrees over the past several million years. It’s the kind of movement you’d expect from a planetary crust floating on a subsurface ocean.

Repeating fast radio burst woke up again on schedule. Now what?

FRB 121102 is one of the few known repeating fast radio bursts, and astronomers are trying to use this new period of activity to understand it better. Some predict the current active phase should end sometime between August 31 and September 9. Will it?

Are there more rogue planets than stars in our galaxy?

A new study suggests there are more rogue, free-floating planets – unconnected to any star – than stars in our Milky Way galaxy. NASA’s upcoming Nancy Grace Roman Space Telescope is expected to begin finding hundreds of them.

Is it possible to hear meteors?

Can you hear a meteor as it streaks overhead? Some people have reported hearing meteors with a sizzling sound like bacon frying. Scientists now say you can, and explain how it happens.
