Feb 21st: Drifting Signals: New Boundaries for Radio Technosignatures
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
Jan 30th: An Exoplanet Found in Another Galaxy
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.
Jan 23rd: The First Exoplanet of JWST
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.
Jan 22nd: Water Worlds – Looking For Life Beyond EarthImages
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?
Jan 12th: Planetary Formation Leads to Strange New Worlds
Time to dive into planetary formation and all the ways scientists have tried to explain stellar systems. Enjoy!
Jan 9th: The Exoplanet That Shouldn’t Exist
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?
Dec 27th: Volcanism on Exoplanets – New Insights from JWST and Beyond
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.
Dec 26th: Proxima-b: The Exoplanet Next Door
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!
Dec 20th: Atmospheric Results from JWST: Carbon Dioxide, Methane, and More
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
