Stars and Galaxies

Astronomers have discovered several fascinating features in galaxy cluster Abell 1213 such as a central galaxy with a 1.66 million light-year-long radio "tail" and remains of galactic mergers.

Even quiet red dwarfs are prone to extreme outbursts that put our sun to shame, with significant implications on the search for alien life.

An image from the Hubble Space Telescope captures an irregular spiral galaxy known as NGC 5486, which lies close to the much larger and well-known Pinwheel Galaxy.

New James Webb Space Telescope observations reveal that the galaxy GS-9209 had its star-forming power abruptly “quenched” by mysterious forces after millions of years of productivity.

When the universe's first stars emerged from the cosmic dark ages, they ballooned to 10,000 times the mass of Earth's sun, new research suggests.

The James Webb Space Telescope (JWST) has dazzled us plenty already, but the best is yet to come from the observatory, mission team members say.

The constellation of Orion the Hunter becomes 'Orion the hunted' during mid-March as its bright stars light up the southern night sky and make a tantalizing target for skywatchers.

Newly released James Webb Space Telescope photos of a giant star that's about to go supernova could shed light on lingering mysteries about cosmic dust.

The moon will find itself in the grip of a cosmic scorpion's claws during the pre-dawn hours Monday (March 13) as it visits the stars in the constellation Scorpius before dawn.

The sky is in transition throughout March as we watch the glorious wintertime stars and bright constellations give way to the somewhat dimmer stars of spring.

Astronomers caught the 1st radio glow from magnetic fields in the universe's largest structure that spans the vastness of space to link galaxies.

Scientists using the Hubble Space Telescope to hunt for protoplanetary discs more than 4,000 light-years away were treated to a rainbow smokescreen filled with stars.

New images from NASA's James Webb Space Telescope (JWST) revealed that a galaxy from the early universe has a previously overshadowed companion that is abundant with star formation.

A rare supermassive black hole found hiding at the dawn of the universe could indicate that there were thousands more of the ravenous monsters stalking the early cosmos.

Twinkling stars blanket this new view of the Carina Nebula, a vast cloud of dust and gas that lies 7,500 light-years from Earth.

In new research, astronomers have mapped the magnetic field in the historic Tycho supernova remnant that accelerates charged particles close to the speed of light.

Thanks to a massive galactic cluster and a light-bending phenomenon predicted by Einstein the James Webb Space Telescope has imaged the same galaxy three times in a single image.

Undoubtedly, one of the most beautiful objects in the night sky is the Great Orion Nebula, also known as M42, which shines in the southwestern sky in March.
