Two rare super-Mercuries discovered in the same star system

While observing the star system HD 23472 , researchers found three super-Earths and two super-Mercuries. This type last of exoplanet is still very rare—counting these two, there are only eight known super-Mercuries. 

Surprise finding suggests 'water planets' are more common

A new study suggests that many more planets may have large amounts of water than previously thought - as much as half water and half rock. All that water is probably embedded in the rock, rather than flowing as oceans.

Astronomers discover two 'super-Earths' orbiting nearby star

The astronomers underlined that the star, these planets are orbiting is the second-coolest star found to host planets after TRAPPIST-1. They added that their finding is the second-most favorable habitable-zone terrestrial planet known so far.

NASA's Webb takes its first-ever direct image of distant world

The exoplanet is a gas giant, meaning it has no rocky surface and could not be habitable. The image shows how Webb's powerful infrared gaze can easily capture worlds beyond our solar system.

NASA's Webb Detects Carbon Dioxide in Exoplanet Atmosphere

This observation of a gas giant planet orbiting a Sun-like star 700 light-years away provides important insights into the composition and formation of the planet.

'Super-Earth' That Could Be an Ocean-Covered Water World

It's called TOI-1452b, and measurements of its size and mass suggest a density profile consistent with a global liquid ocean. An exoplanet is just 100 light-years from Earth

2 Super-Earths Orbiting a Nearby Star

Two new worlds of probable rocky mineral goodness have just been found orbiting a star close to our own cosmic neighborhood. 

NASA Discovers Super-Earth That May Support Life

Scientists have discovered a Super-Earth that is four times the mass of our planet and takes just 10.8 days to complete a whole year.

TESS Mission Found 5,000 Exoplanets

TESS reached a milestone. We now have over 5,000 exoplanet candidates. Scientists have a lot of work to do confirming them.

Astronomers Find 70 Planets Without Stars In Our Galaxy

Using telescopes from around the world, a team of astronomers recently discovered 70 additional free-floating planets (FFPs), the largest sample of “Rogue Planets” discovered to date in the Milky Way.

Most nearby rocky exoplanets are quite unlike anything in our Solar System

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.    

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.
