People around the world are being invited to learn how to hunt for planets, using two new online apps devised by scientists at the University of Texas at Austin and UC Santa Cruz.
Astronomers may have made an important discovery--or not. They've found a possible exomoon, which is a moon orbiting a planet beyond our sun.
There is excitement in astronomy and planetary science departments worldwide as the new Gemini Planet Imager, housed in the Gemini South Telescope in the Chilean Andes, turns its razor-sharp gaze to the skies.
Astronomers are getting closer to finding a rocky, water-rich planet like earth after proving new technology that can spot minute changes to starlight.
With the help of a bright star, astronomers have spotted a new exoplanet the size of Neptune. The finding could help researchers better understand this double star system.
A team of researchers has directly imaged a very rare type of brown dwarf that can serve as a benchmark for studying objects with masses that lie between stars and planets.
Massive planets called "super-Earths" are common in our galaxy, the Milky Way. Now, though, scientists have found that these planets are far more likely to have an Earth-like climate than previously thought.
An international team of astronomers has discovered the first Earth-mass planet that transits, or crosses in front of, its host star. KOI-314c is the lightest planet to have both its mass and physical size measured.
More than three-quarters of the planet candidates discovered by NASA's Kepler spacecraft have sizes ranging from that of Earth to that of Neptune, which is nearly four times as big as Earth.
Method will help scientists determine the mass of exoplanets that are not measurable in any other way.
Atmospheric peculiarities similar to Earth and a few other planets may also be common to billion other planets and moons in the galaxy, researchers find.
A team of astrophysicists at the German Aerospace Center, together with European colleagues, has discovered the most extensive planetary system to date, with striking similarity to our own Solar system! Seven planets circle the star KOI-351 – more than in other known planetary systems.
