Orbiting the cool #DwarfStar K2-18, the exoplanet, 2.6 times the radius of #Earth, lies in what #Nasa calls the habitable zone, a region around a star where planets with liquid #water may be present.
Nasa says distant #exoplanet could have rare #WaterOcean and possible hint of life | Nasa | The Guardian

The #video lasts 1 minute but it corresponds to 10 hours.
The big dish is a decommissioned radio #telescope. In the background there is the 3.6-m telescope with its #exoplanet-hunting instrument #HARPS

"Is Earth an Oddball?" by @NASAExoplanets - After discovery of thousands of exoplanets, it's apparent star formation includes planet formation. But no #exoplanet so far is at all similar to Earth. No signs of life yet either. Keep looking.🔭👀 https://exoplanets.nasa.gov/blog/1599/is-earth-an-oddball/ #astronomy

Watch an Actual Exoplanet Orbit its Star for 17 Years
Astronomers have been studying the exoplanetary system Beta Pictoris for 17 years, watching as an enormous planet is orbiting the star. This is one of the most dramatic views ever seen with the "direct method" of exoplanet astronomy, and you can just watch an actual planet orbit an actual star. Beta Pictoris b is the perfect world for this observation; it's far from its star, large, and extremely bright. Astronomers will have watched the planet complete one full orbit around the star in another six years.

Recently I revisited the giant #exoplanet Qatar-1 b and recorded its transit with my #eVscope. It's not much larger than Jupiter and has 1.294 Jovian masses, but #Qatar1b orbits in just 1.4 days around its K-type host star and thus is a #HotJupiter planet.

First time #exoplanet #conference right next to a #lighthouse. I believe the analogy with the #firefly will be so easy 😁
