Stars and Galaxies

A powerful and spectacular cosmic dance that began a billion years ago will lead to a collision and merger between two galaxies and the supermassive black holes at their hearts.

Hubble Space Telescope delivers a stunning new image of stellar gas and dust in the Orion Nebula

A mesmerizing new photo captures bright, golden swirling clouds of gas that generate an exceptionally high rate of star formation.

New evidence suggests the culprit for the cosmic assault presented by cosmic rays may be the shock waves from exploding stars.

Astronomers have long considered Betelgeuse a candidate for a long-overdue supernova within our galaxy. Yet the red supergiant appears to be recovering following a mysterious 2019 event.

Astronomers have found at least one dusty galaxy masquerading as a high-redshift galaxy, complicating the search for the first galaxies.

Astronomers have spotted the initial stages of a clash and merger between two spiral galaxies using the Gemini North telescope, offers a glimpse at the fate of our galaxy.

Zoom in to see the incredible Cartwheel Galaxy, which is 500 million light-years away from us.

More than 25%of the stardust in our planetary system may have been seeded there when supergiant stars exploded.

The Hubble Space Telescope has imaged globular cluster NGC 6638, located in the constellation Sagittarius.

The European Space Agency is considering ways to redesign a major X-ray space telescope after a number of ESA member states have backed out of the project.

A distant neutron-star merger unleashed one of the most powerful short gamma-ray bursts (GRB) ever seen.

Galaxy clusters allow us to study a broad range of rich processes — including magnetism and plasma physics — in environments we can't recreate in our labs.

The James Webb Space Telescope peered through dust and gas to reveal star formation in a rare wheel-shaped galaxy that formed in a long-ago galactic crash.

The James Webb Space Telescope has caught a glimpse of the most distant star known in the universe, which had been announced by scientists using Webb's predecessor Hubble only a few months ago.

We have also seen headlines claiming Webb has found “the oldest galaxies we have ever seen”, but what does that mean?

Using a cosmic relic from the universe's earliest moments researchers have made the earliest detection of a mysterious form of matter that makes up 85% of the universe's mass.

The Hubble Space Telescope is seeing double in a new image of a distant galaxy called SGAS J143845+145407.

New research shows how the push and pull inaction of energy and gravity shapes the cosmic web of 30 Doradus — the Tarantula Nebula — a site of rapid star formation.
