- Exoplanets - NASA Science
Overview Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way (“Small” meaning within thousands of light-years of our solar system; one light-year equals 5 88 trillion miles, or 9 46 trillion kilometers )
- The nearest potentially habitable planet to Earth – Exoplanet . . .
From University of New South Wales Australia UNSW Australia astronomers have discovered the closest potentially habitable planet found outside our solar system so far, orbiting a star just 14 light-years away
- Discovery Alert: A Super-Earth in the Habitable Zone
The discovery: A “super-Earth” ripe for further investigation orbits a small, reddish star that is, by astronomical standards, fairly close to us – only 137 light-years away The same system also might harbor a second, Earth-sized planet Key facts: The bigger planet, dubbed TOI-715 b, is about one and a half times as wide as Earth, and orbits within the “conservative” habitable zone
- Super-Saturn: astronomers find a massive ring system around an . . .
Courtesy University of Rochester Astronomer Eric Mamajek, then at the University of Rochester, and his co-author from the Leiden Observatory, The Netherlands, have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is of enormous proportions, much larger and heavier than the ring system of Saturn
- Discovery Alert: Watch the Synchronized Dance of a 6-Planet System . . .
Among the outermost planets, a pattern of four orbits for every three of the next planet out (a 4 3 resonance) is repeated twice And these resonant orbits are rock-solid: The planets likely have been performing this same rhythmic dance since the system formed billions of years ago
- NASA’s next planet hunter will look closer to home
The Transiting Exoplanet Survey Satellite (TESS) is an astrophysics Explorer-class mission between NASA and MIT After launching in 2017, TESS will use four cameras to scan the entire sky, searching for planets outside our solar system, known as exoplanets

Find your dream world This set of travel posters envision a day when the creativity of scientists and engineers will allow us to do things we can only dream of now you can take a virtual trip to several alien worlds and maybe even plaster your living room with this planetary art, available free for downloading and printing
- Background Information | What is Exoplanet Watch? – Exoplanet . . .
A light curve shows the change in brightness of a star when an exoplanet passes in front of the star We can't see the exoplanet directly using the transit method, but we can see the effect the exoplanet has on its star's brightness as it transits
