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.

The discovery or an ultra-tiny white dwarf could reveal how stars smaller than Jupiter are born.

Twinkling stars can throw off telescope observations. To correct that, observatories like the Gemini North telescope in Hawaii create 'artificial stars' with lasers to hone their equipment.

The powerful James Webb Space Telescope captured a starburst complex in the Large Magellanic Cloud, with stunning results.
