It's proposing two approaches: either shoot dangerous asteroids with an ion cannon — or ram it out of orbit. The post Jeff ...

For decades, astronomers have struggled to differentiate giant planets from brown dwarfs, a class of objects more massive ...

A study published in Science Advances sheds new light on the mysterious origins of free-floating planetary-mass objects (PMOs)—celestial bodies with masses between stars and planets. Led by Dr. Deng ...

Long ago, a planetary object eight times the mass of Jupiter may have once visited the solar system and altered the orbits of the four outer planets-Jupiter, Saturn, Uranus, and Neptune. It could ...

The NASA project NEOWISE, which has given astronomers a detailed view of near-Earth objects – some of which could strike the Earth – ended its mission and burned on reentering the atmosphere after ...

Work from the DiSCo program (Discovering the Composition of Trans-Neptunian Objects) has uncovered the existence of three main groups of trans-Neptunian objects (TNOs) in the outer Solar System.
