Stars and Galaxies

Astronomers using the James Webb Space Telescope have detected the oldest known examples of complex organic molecules in the universe, a new study reports.

A new supernova that burst into the night sky in May 2023 should remain visible in the Pinwheel Galaxy for some time, astronomers say.

Hundreds of lines made from a multitude of gases have been discovered extending outward from the black hole at the center of our galaxy.

One of the brightest stars in the night sky has been getting oddly brighter, prompting speculations that it might soon explode in a supernova. Can we really expect that celestial spectacle?

NASA's Hubble Space Telescope has snapped a stunning image of a jellyfish galaxy, whose cosmic tentacles host massive amounts of star formation.

The two protesters burst from their cocoons of gas and dust in Lupus 3, a vast stellar nursery located about 500 light-years from Earth.

A star in the Pinwheel Galaxy has exploded into a new supernova that was confirmed just last week. Here's how to see it for yourself in the night sky.

The close proximity of supernova 2023ifx and the amount of observations gathered since its discovery may lead to major advances in stellar death forecasting.

Astronomers are snooping on the Milky Way's galactic neighbors to gain insights about the ancient galaxies being viewed by the James Webb Space Telescope.

A star explosion in deep space is visible in amateur telescopes, although folks have had to battle low lighting conditions, haze and the occasional satellite trail to see it in action.

In a distant star system, a sunlike star orbits an invisible object that may be the first example of a 'boson star' made of dark matter, new research suggests.

A newly discovered supernova can be watched as it develops in real-time online and for free. The livestream will begin at 6:30 p.m. EDT (2230 GMT) on Friday, May 26.

During the last few days, astronomers have been pointing their telescopes toward a familiar celestial object in our spring night sky for a look at a rare event: A new supernova.

A young NASA mission spotted strange movements of X-rays in the supernova remnant known as Cassiopeia A, which may include an extremely dense and small star.

The stellar companions of more than a dozen stars orbiting the supermassive black hole at the center of the galaxy have gone missing — and astronomers want to know why.

Astronomers have made the first detection of a supernova in radio waves, finding that an exploding white dwarf star was feeding from a companion star like a cosmic vampire before it blew.

The radiation belt around the ultracool dwarf star, located around 19 light-years from Earth, is doubled-lobed like the radiation belts around Jupiter — but it's 10 million times brighter.

The eRosita bubbles of hot gas that extend 36,000 light-years out from our Milky Way galaxy are more complex than previously thought, a new study reveals.

The James Webb Space Telescope has shown that supermassive stars may lurk at the heart of globular clusters born shortly after the Big Bang.

New measurements suggest that the traditional view of the Milky Way as a galaxy with four major spiral arms extending out from a thick centralized bulge of stars could be wrong.
