Astronomers and geologists have recently concluded that most rocky planets orbiting nearby stars are more diverse and exotic than previously thought, with types of rocks not found anywhere in our Solar System.
The researchers have identified a new class of habitable planets, dubbed 'Hycean' planets - hot, ocean-covered planets with hydrogen-rich atmospheres - which are more numerous and observable than Earth-like planets.
Astronomers using the Atacama Large Millimeter Array (ALMA) have spotted presence of a disc around a Jupiter-like exoplanet 400 light years away that could provide the raw material for up to three satellites the size of Earth’s Moon.
That incredible distance made the original discoverers of the planet back in 2011 think it was “rogue”. But a new research shows that the planet is in fact gravitationally bound to a star, just as an absurdly far distance.
The molecule hydroxyl (HO) is common on Earth. Now, for the first time, astronomers have conclusively detected it in the atmosphere of an ultra-hot Jupiter, WASP-33b.
Researchers report the discovery of a super-Earth orbiting the star GJ 740, a red dwarf star situated some 36 light years from Earth. Its mass is around 3 times the mass of Earth.
The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn.
A new study of the seven Earth-sized exoplanets around TRAPPIST-1 indicate that all 7 planets are extremely similar to each other in makeup, but potentially quite different from Earth.
As it turns out, organic material, liquid water, sunlight and a large moon might not be enough to ensure an exoplanet’s habitability. It also may depend on whether enough radioactive elements are present in the planet’s core.
We’ve discovered a number of “lava planets” or “magma worlds” throughout the Milky Way. These planets are in such close proximity to their stars that their surface is literally melted into a perpetual ocean of lava.
Recently, an international team of scientists, combined data from Kepler Space Telescope and Gaia Observatory revealed is that half of the Sun-like stars in our Universe could have rocky, potentially-habitable planets.
The ESA’s CHEOPS (Characterizing Exoplanets Satellite) mission has announced its first discovery. It’s called WASP-189 b, and it’s a blistering hot temperature of 3,200 °C. They’re calling the planet an “ultra-hot Jupiter.”
Once a star left the gravitational embrace of its solar system, its pretty much destined to drift through interstellar space forever. Astronomers call these drifters “rogue planets” and one of them have been found recently.
Astronomers have discovered what appears to be an intact, Jupiter-size planet ( WD 1856 b ) whipping around a compact white dwarf, the remnant of a Sun-like star.
Researchers have found an Earth-size exoplanet with a pi-like 3.14-day period. Whirling around its star at some 291,000 kph, the planet’s surface temperature is estimated at around 176 degrees Celsius.
