Fluffy strands of cosmic gas and dust illuminated by bright young stars form a beautiful cloudscape in a neighboring nebula.

Astronomers using the powerful James Webb Space Telescope to survey distant galaxies spotted an unusual, chance phenomenon called an "Einstein ring." It's not an actual object, but a warped, mind-bending optical illusion.

The Large UV/Optical/IR Surveyor (LUVOIR) telescope has been imagined as a habitable planet hunter, but it could be so much more

NGC 4536 is a starburst galaxy with rapid star formation due to gas compression. Its bar-like structure channels gas toward the nucleus, fueling intense star birth. The hot blue stars formed quickly and exploded,

A century ago, Edwin Hubble revolutionized our understanding of the universe by proving that the Milky Way is just one of many galaxies in an ever-expanding cosmos. This breakthrough led to the discovery of the universe's vast scale and its continuous expansion,

The emission nebula, known as Sh2-284, is an immense region of gas and dust that fuels new star formation. It lacks elements heavier than hydrogen and helium, much like the environment of the early universe.

Hubble’s latest image reveals the Small Magellanic Cloud (SMC), a nearby dwarf galaxy visible from Earth without a telescope. Though it appears as a faint smudge in the sky, Hubble’s high-powered lenses capture an astonishing level of detail,

CAPE CANAVERAL, Fla. (AP) — The Webb Space Telescope has captured a plume of gas and dust streaming from a star in the making, with a spiral galaxy as a stunning backdrop.

Vivian Poulin asks if the tension between a direct measurement of the Hubble constant and constraints from the early universe could be resolved by new physics.
