NASA's James Webb Space Telescope has been unwaveringly focused on our universe. With its unprecedented power to detect and ...

TOI-6894 b, the largest exoplanet relative to its host star yet seen, doesn’t fit the most widely accepted formation model ...

A rare Jupiter-sized planet AT2021uey b was found 3,200 light-years away using microlensing, a method based on Einstein's ...

These are massive gas giants with temperatures exceeding 1,700°C (3,100°F). However, since the red dwarf sun is so cool the planet's atmosphere is just 147°C (300°F) which has big implications ...

In 2020, astronomers detected WD 1856+534 b, a gas giant that orbits a star 81 light-years from Earth. This exoplanet, which is roughly six times the mass of Jupiter (making it a "super-Jupiter ...

The radiation probably originates from the scorching-hot wreckage left behind by a giant planet’s annihilation. This discovery stems from four decades of X-ray observations of the Helix Nebula ...

It has a mass about 13 times that of Jupiter, and is thought to have the structure and chemical composition of a giant gas planet, though its true characteristics have not yet been determined.

An artist’s illustration depicts the supermassive black hole at the center of the Milky Way galaxy, known as Sagittarius A*. It’s surrounded by a swirling accretion disk of hot gas and dust.

Despite the darkness, the astronomers were still able to determine that the white dwarf was orbited by two objects: a brown dwarf (an object larger than a gas giant planet, but smaller than a star ...

A 2020 microlensing event was caused by a planetary system with an Earth-like planet and brown dwarf. The star type was uncertain. The team has determined that the star is a white dwarf, a system ...
