NASA's TESS satellite has discovered a "Second Earth." What's even more exciting is there may be an entire universe full of these possibly habitable exoplanets.
Extrasolar Planets, or just exoplanets for short, are planets that have been discovered orbiting stars other than the Sun. They were first confirmed to exist in 1990 with the discovery of Lich.

It was thought likely that distant worlds orbiting stars similar to our Sun would go through water-rich phases. This would happen when the young, dim star of an icy, lifeless planet -- such as early Earth -- starts warming, becomes Sun-like, and melts the ice on planets orbiting it...
Thousands of exoplanets,or planets outside our solar system, have been discovered over the past few decades. My research group wanted to understand how habitable these planets are, and whether these exoplanets also have wild obliquities, or whether they have moons to stabilize them like Earth do...
Planets orbit their parent stars while separated by enormous distances – in our solar system, planets are likegrains of sandin a region the size of a football field. The time that planets take to orbit their suns have no specific relationship to each other. ...
Orbiting other stars C. Developing new telescopes D. Finding more exoplanets 2. What’s an exoplanet? A. It’s a planet like Earth B. It’s a planet outside our solar system C. It’s a planet orbiting the sun D. It’s a planet where life have developed ...
They have different, what're called host stars. The study of exoplanets has been getting more and more exciting; hundreds of them have been discovered so far. This is quite remarkable in view of the fact that the discovery of the first exoplanets was confirmed only in the mid-1990s. Now ...
Planets tug on the stars they orbit, moving them a tiny bit in the sky. Astronomers will use TOLIMAN to watch Alpha Centauri for these little "wobbles," hoping to find what the transit method struggles to see: an exoplanet that isn't orbiting perfectly edge-on between us and it...
Observations of terrestrial exoplanets will best be done from space. In the 2015-2025 time frame it will be possible to perform spectroscopic analyses of Earth twins orbiting other stars, and to search for the signature that life may imprint on the composition of their atmospheres.A. Quirren...
