Astronomers Define the “Really Habitable Zone”. Planets Capable of Producing Gin and Tonic

A hospitable star that doesn’t kill you with deadly flares. A rocky planet with liquid water and an agreeable climate. Absence of apocalyptic asteroid storms. No pantheon of angry, vengeful, and capricious gods. These are the things that define a habitable planet.

Now some scientists are adding one more criterion to the list: gin and tonic.

Are Low Density “Cotton Candy” Exoplanets Actually Just Regular Planets With Rings?

There’s a type of exoplanet that astronomers sometimes refer to as cotton candy planets, or super-puffs. They’re mysterious, because their masses don’t match up with their extremely large radii. The two characteristics imply a planet with an extremely low density.

In our Solar System, there’s nothing like them, and finding them in distant solar systems has been puzzling. Now a pair of astronomers might have figured it out.

During A Lunar Eclipse, It’s A Chance To See Earth As An Exoplanet

There are several ways to look for alien life on distant worlds. One is to listen for radio signals these aliens might send, such as SETI and others are doing, but another is to study the atmospheres of exoplanets to find bio-signatures of life. But what might these signatures be? And what would they appear to our telescopes?

CHEOPS Just Opened Its Eyes to Start Studying Known Exoplanets, We Should See the First Picture in a Few Weeks

The CHEOPS (CHaracterisingĀ ExOPlanetsĀ Satellite) spacecraft just opened the cover on its telescope. The spacecraft was launched on December 18th 2019 and has so far performed flawlessly. In one or two weeks we could get our first images from the instrument.
