Aside from our own solar system, one of the most studied stellar systems lies about 40 light-years away in the direction of the constellation Aquarius. Seven rocky exoplanets orbiting the TRAPPIST-1 star. more about it 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.
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?
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!
Astronomers estimate there are more planets in our galaxy than there are stars. Just how many is that?
The James Webb Space Telescope has made its first observations of the TRAPPIST-1 system and measured the temperature of TRAPPIST-1b!
Did you know that the discovery of other planets in orbit around other stars is a very recent one? Only 25 years ago, we had no idea there were any planets in our galaxy besides those in our solar system. Now, not only have we discovered them, but astronomers estimate there are trillions of them. There are so many exoplanets out there that every star in our galaxy could have at least one.
Kepler-22b is one of the first exoplanets confirmed by the Kepler Space Telescope that resides in the habitable zone.
Do you know that we have interesting class of exoplanets? This type of planets do not have a home sun. These rogue worlds travel the distance between the stars, they live in the cold, dark interstellar regions of the galaxy. More with @DeepAstronomy
