Following the 3,000th orbit of NASA's AWE (Atmospheric Waves Experiment) aboard the International Space Station, researchers ...

This is the fourth comet Gröller has discovered, but given its extraordinary distance, it was the most exciting find, he says ...

An international team of astronomers working with the Canada France Hawaii Telescope have discovered a whopping 128 more ...

Planets change orbit shape around Neptune’s size. Metal-rich stars help giant planets form. Eccentric orbits suggest chaotic planet formation.

Consequently, even though it is one of the closest stars to Earth, such that its light takes only six years to get here, it ...

Satellites come in all shapes and sizes, but there aren't any that look quite like SPHEREx, an infrared observatory NASA ...

The planets are all too hot for life as we know it, but astronomers haven’t given up searching for more planets in Barnard's ...

These gases — composed of carbon, hydrogen, and a halogen, like chlorine — are mostly made by bacteria, algae, fungi, and ...

The shape of a planet's orbit is one of its fundamental properties, along with its size and distance from its host star.

Astronomers have identified a quartet of small rocky planets orbiting Barnard's star - one of our closest stellar neighbors - ...

A huge haul of 128 newfound satellites might be a hint of past collisions in the planet’s orbit, or something else.

"It's remarkable what we've been able to learn about the orbits of planets around other stars using the Kepler Space Telescope," Petigura said. "The telescope was named after Johannes Kepler ...
