A team of international researchers has confirmed the discovery of an Earth-like exoplanet that may have the right conditions ...

There's a new race in space, but it's not where you might think. It's happening close to home – in the nearest bit of space, ...

"With an orbital period of 570 days, it is a relatively cold gas giant planet," said Guðmundur Stefánsson of the University ...

Scientists found that an asteroid impact carved two massive canyons on the moon in minutes. High-speed debris helped shape ...

NASA and European scientists explain how they calculate the probability of the space rock 2024 YR4 impacting our planet, and why it’s not yet time to worry.

Space agencies have systems in place to spot, track, and forecast the future orbits of potentially hazardous asteroids.

When we first began searching for planets around other stars, one of the surprising discoveries was that there are planets orbiting white dwarfs. The first exoplanets we ever discovered were white ...

Or, for those who remember vinyl records, think of the grooves around the central hub as the planets' orbits. Earth’s orbit lies in that same plane, so from our perspective, we cannot see the ...

Astronomers have long relied on two main methods to detect exoplanets—the transit method, which looks for dips in a star’s brightness when a planet passes in front of it, and the radial velocity ...

Data from the Gaia spacecraft shows that even unassuming stars can host monumental companions like massive planets.

These planets may be nowhere near each other in their solar orbits but are visible from the perspective of Earth.

Scientists also discovered a second planet, a brown dwarf orbiting another low-mass star. Gaia-5b orbits the Gaia-5 star, around 134 light-years away from Earth.
