stars

A study of 91 pairs of stars finds that about 8%, or one in 12, swallowed up a planet at some point in their lives.

Recent observations show that some white dwarf stars suddenly stop cooling. Now, scientists propose a 'fountain of youth' mechanism that may explain how these stellar husks avoid death for billions of years.

The ancient obect Gz9p3, which appeared as a single point of light through the Hubble Space Telescope, is actually one of the most enormous galaxies in the early universe, James Webb Space Telescope observations reveal.

Two new James Webb Space Telescope images show off massive bubbles carved out of a stellar nursery by giant, baby stars growing in a nearby galaxy.

A nova outburst visible to the naked eye is expected to decorate the night sky this year with a "new star" that will briefly become as bright as the North Star, offering a once-in-a-lifetime stargazing opportunity.

Complex organic molecules spotted by the James Webb Space Telescope may hint at how habitable planets form.

The James Webb Space Telescope zoomed in on galaxy GN-z11, which existed just 430 million years after the Big Bang, to reveal what may be some of the oldest stars in the universe.

The Hubble Space Telescope's latest image is a riot of orange, blue and violet — and a lesson in how plucky young stars clear their dusty neighborhoods.

A group of extremely bright stars may be slowly reshaping the Orion Nebula and stopping one of their neighbors from forming planets, new James Webb Space Telescope observations suggest.

Passing stars may have altered Earth's orbit, and its climate, many times throughout cosmic history. New research digs into what that means when it comes to understanding our planet's past.
