Hubble confirms Earth-sized exoplanet only 22 light years away

The chances of finding extraterrestrial life have improved slightly after NASA announced that its Hubble Space Telescope has confirmed the size of an Earth-sized exoplanet only 22 light-years from Earth.

Scorching, Seven-Planet System Revealed by New Kepler Exoplanet List

A system of seven sweltering planets has been revealed by continued study of data from NASA's retired Kepler space telescope: Each one is bathed in more radiant heat from their host star per area than any planet in our solar system.

Mists of tiny quartz crystals on a giant hot exoplanet

Astronomers have detected silica in exoplanet atmospheres before. But this is the first time they’ve found particles of what appears to be pure quartz. 

Scientists see the first ever "afterglow" of two ice giant planets colliding

Researchers were caught by surprise when they observed what they believe to be the aftermath of two giant planets colliding.

JWST Discovers Starless, Planet-Like Objects

in the Trapezium cluster, scientists have found dozens of planet-like objects roughly the mass of Jupiter untethered to any star, drifting through the galaxy in gravitationally-bound pairs.

Webb Discovers Methane, Carbon Dioxide in Atmosphere of K2-18 b

A new investigation with NASA's James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide.

Super Hefty Exoplanet Is Denser Than Steel, Scientists Say

A newly discovered exoplanet has characteristics so peculiar that astronomers think it must have experienced a giant collision some time in its past.

Newly Discovered World Challenges Our Understanding of Planets

TOI-4860b happens to orbit a tiny star, completing each lap in just 1.52 days. It joins a small number of worlds that pose a fascinating puzzle - there are currently no known formation pathways for such chonkin' planets around such small stars.

Ethereal New Image Reveals The Birth of Giant Jupiter-Like Worlds

By using the Very Large Telescope and the Atacama Large Millimeter/submillimeter Array, astronomers have identified clumps in the thick material around a star named V960 Mon that could gravitationally collapse to form the seeds of planets like Jupiter.

Massive, Cloud-Like Planet Discovered That's as Fluffy as Cotton Candy

Exoplanet WASP-193b, is nearly 50 % bigger than Jupiter but it's so light and fluffy that its overall density is comparable to that of cotton candy. It's just a hair over 1% of the density of Earth.

We Just Got The First Evidence of Two Planets Sharing The Same Orbit

The system in which the discovery was made is already famous: PDS-70. It was here that we saw, for the first time, direct images of not just one but two exoplanets in the process of forming, baby gas giants named PDS-70b and PDS-70c

'Like a mirror': Astronomers identify most reflective exoplanet

A scorching hot world where metal clouds rain drops of titanium is the most reflective planet ever observed outside of our Solar System.

We May Have Just Found a 'Cannibal' Planet

A gas giant exoplanet 634 light-years away has a quirk in its atmosphere that suggests it may have swallowed a smaller world.

Record-Breaking Planet-Like Object Found That's Hotter Than The Sun

An object orbiting a star 1,400 light-years away is seriously confronting our notions of what's possible in the Universe.

In a first, astronomers discover 'radiation belt' outside solar system

The belt was discovered around a brown dwarf known as LSR J1835+3259 and is 10 million times more intense than Jupiter's.
