(Phys.org)—NASA's Kepler spacecraft continues its fruitful exoplanet hunt with the newest discovery of two super-Earth-sized alien worlds. The newly detected planets are orbiting a nearby sun-sized star known as HD 3167, ...
(Phys.org)—An international team of astronomers led by Joshua Pepper of the Lehigh University in Bethlehem, Pennsylvania, has detected an extremely inflated sub-Saturn exoplanet orbiting a bright subgiant star. The newly ...
(Phys.org)—An international team of astronomers has discovered three new exoplanets using a Qatar-based planet-searching survey. The newly discovered gas giant exoworlds belong to the so-called "hot Jupiter" family of planets ...
(Phys.org)—HD 189733b, located some 64 light years away, is the closest "hot Jupiter" exoplanet to Earth. Thanks to its proximity, it is a great target for atmospheric observations. Now, an international team of astronomers ...
Astronomers have used the NASA/ESA Hubble Space Telescope and the NASA Spitzer Space Telescope to study the atmospheres of ten hot, Jupiter-sized exoplanets in detail, the largest number of such planets ever studied. The ...

(Phys.org)—Exoplanet hunters have so far found hundreds of alien worlds using the transit method. They observe the visual brightness of the star, which drops when a planet crosses in front of the parent star's disk. However, ...
Astronomers using NASA's Hubble Space Telescope have discovered an immense cloud of hydrogen dubbed "The Behemoth" bleeding from a planet orbiting a nearby star. The enormous, comet-like feature is about 50 times the size ...
