In a new study published in the Astronomical Journal, researchers used the known population of exoplanets to set better thresholds for planetary effects on signals from ETIs (extraterrestrial intelligences). More at #365DaysOfAstro
Astronomers have found evidence of a possible planet outside of our Milky Way galaxy. If confirmed, this is the first time that a planet has been detected in another galaxy. It is located in the spiral galaxy Messier 51, also called the Whirlpool Galaxy.
The James Webb Space Telescope has detected its first exoplanet. Its name is LHS 475b, and astronomers believe it is remarkably similar to our own home planet.
Wherever we find liquid water on Earth, we find life, so it makes sense to search for water across the Universe. But what about worlds which are completely covered in water, oceans hundreds of kilometers deep. Can there be too much water?
Time to dive into planetary formation and all the ways scientists have tried to explain stellar systems. Enjoy!
Astronomers have found a planet around a red giant star that should have been destroyed, yet it still exists, leaving astronomers to wonder why the planet is still there. So what’s the puzzle?
Up until now, the quest to find evidence of active volcanism on other worlds has been limited to our own solar system. With the advent of the JWST era, however, more possibilities have opened up.
Proxima Centauri-b is the closest exoplanet to Earth and lies within the habitable zone of its star. And not only that, but it’s in the habitable zone!
Exoplanet discoveries have been piling up faster and faster over the last decade. With the addition of JWST’s capabilities, previously discovered exoplanets are now being analyzed for their atmospheric composition, and the results are intriguing. Today SETI Live discuss about exoplanet K2-18 b that was found to contain carbon dioxide and methane
Astronomers estimate there are more planets in our galaxy than there are stars. Just how many is that?
