Astronomers have, for the first time, pinned down both the mass and distance of a planet that drifts through the galaxy ...

Quite far beyond the Milky Way is a lone planet that astronomers found new information about. For the first time, scientists ...

Scientists have discovered a rogue planet roaming the Milky Way after combining observations from Earth and a space telescope ...

Planets may begin forming much earlier than scientists once believed during the final stages of a star s birth, not afterward. This bold new model, backed by simulations from researchers at SwRI, ...

The James Webb Space Telescope recently discovered dozens of inexplicable 'rogue' planets floating through space in pairs. Now, a new study may explain the mystery behind these rare "JuMBOs". When you ...

An object eight times the mass of Jupiter may have swooped around the sun, coming superclose to Mars' present-day orbit before shoving four of the solar system's planets onto a different course. When ...

A rogue planet is a world that has been ejected from the planetary system in which it originally formed. Because rogue planets do not orbit a parent star, they are cast adrift into interstellar space.

According to the latest studies led by Heidelberg University astronomers, low-mass stars quite often host Earth-like planets. Data collected as part of the CARMENES project were the basis of this ...

This image from a simulation of atmospheric flow shows temperature patterns on one of the newly discovered planets (61Virb), which is hot enough that it glows with its own thermal emission. A movie of ...

The original version of this story appeared in Quanta Magazine. When Galileo Galilei, a mathematician at the University of Padua, trained a spyglass of his own creation on the sky, he was overwhelmed ...

While most planets that we are familiar with stick relatively close to their host star in a predictable orbit, some planets ...
