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.

'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.

Astronomers spot a star swallowing a planet

Scientists have observed a star swallowing a planet for the first time. Earth will meet a similar fate in 5 billion years.

'Forbidden' planet orbiting a small star

The host star, TOI-5205, is just about four times the size of Jupiter, yet it has somehow managed to form a Jupiter-sized planet, which is quite surprising.

Exoplanet 31 light years away could be habitable

Astronomers have discovered a rocky exoplanet about a few dozen light years away from Earth with conditions that could make it habitable.

Earth-sized planet found just 72 light years away

An international team of astronomers has confirmed the existence of K2-415b, an Earth-sized exoplanet circling an M dwarf star, just 72 light years away from Earth. 

Incredible Footage Shows Planets Circling a Star Light-Years Away

The video shows four dots of light moving in partial concentric circles around a black disk at their center. What you're actually looking at is a planetary system.

A Rare Earth-Sized Planet in a Habitable Zone

TOI 700 e has been confirmed orbiting inside the habitable zone of its star, TOI 700. TOI 700 is a small, cool star (known as an M dwarf star), located around 100 light-years away from us in the Dorado constellation.
