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.

NASA's Webb Confirms Its First Exoplanet

Researchers confirmed an exoplanet using NASA’s James Webb Space Telescope for the first time.Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth's diameter.

Two alien water worlds with oceans 500 times deeper than Earth's

Two exoplanets – Kepler-138 c and Kepler-138 d – appear to have oceans at least 1,600 km deep. That’s about 500 times deeper than the average depth of Earth’s oceans. However, they could be much warmer and under very high pressure.

Discovery Alert: Massive Planet is a 'Hulk' among Super-Earths

The planet, nearly 10 times Earth’s mass, orbits a small, red-orange star about 200 light-years away. This planet is extremely hot, with an estimated temperature of 1,050 Celsius.

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.
