New class of habitable exoplanets

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.

In a first, ALMA spies huge moon-forming disc around exoplanet

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.

Huge Planet Orbiting its Star at 6,000 Times the Earth-Sun Distance

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. 

Hydroxyl Seen for the First Time in an Exoplanet

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. 

A new super-Earth detected orbiting a red dwarf star

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.

A 'super-puff' planet like no other discovered

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.

Update on the 7 Earth-sized planets orbiting nearby

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.

Radioactive elements may be key to exoplanet habitability

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.

Planets Close to Their Stars Have Magma Oceans

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.

95% Chance of an Earth-Like Planet Within 20 Light Years

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.

Cheops Finds an Utterly Alien World

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.”

An Earth-Mass Planet Without A Star Found

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.

In a first, intact planet found in close orbit around white dwarf

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 find exoplanet with pi-like 3.14-day orbit

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. 

Actual Picture of Multiple Planets Orbiting a Star

Direct images of exoplanets are pretty rare. This is the first direct image of multiple exoplanets orbiting a star similar to our Sun taken by The European Southern Observatory’s Very Large Telescope (VLT).
