Hubble Traces Star Formation in a Nearby Nebula

NGC 261 blooms a brilliant ruby red against a myriad of stars in this new image from NASA’s Hubble Space Telescope. Discovered on Sept. 5, 1826 by Scottish astronomer James Dunlop, this nebula is located in one of the Milky Way’s closest galactic companions, the Small Magellanic Cloud (SMC). The ionized gas blazing from within […]

Hubble Pinpoints a Dim, Starry Mini-galaxy

A glittering collection of stars shines against a background of much more distant galaxies in this view from NASA’s Hubble Space Telescope of the Pegasus Dwarf spheroidal galaxy, also known as Andromeda VI.  The Andromeda galaxy, also known as Messier 31, is the Milky Way’s closest grand spiral galaxy neighbor, and is host to at […]

Cassiopeia A, Then the Cosmos: 25 Years of Chandra X-ray Science

By Rick Smith On Aug. 26, 1999, NASA’s Chandra X-ray Observatory opened its powerful telescopic eye in orbit and captured its awe-inspiring “first light” images of Cassiopeia A, a supernova remnant roughly 11,000 light-years from Earth.

Webb Finds Early Galaxies Weren’t Too Big for Their Britches After All

It got called the crisis in cosmology. But now astronomers can explain some surprising recent discoveries. When astronomers got their first glimpses of galaxies in the early universe from NASA’s James Webb Space Telescope, they were expecting to find galactic pipsqueaks, but instead they found what appeared to be a bevy of Olympic bodybuilders.

Hubble Captures Unique Ultraviolet View of a Spectacular Star Cluster

Roughly 210,000 light-years away, the Small Magellanic Cloud (SMC) is one of our Milky Way galaxy’s closest neighbors. In fact, this small galaxy is one of the Milky Way’s “satellite” galaxies, which orbit our home spiral galaxy. Nested within the SMC is this spectacular star cluster, known as NGC 346. Its hot stars unleash a […]

Hubble Reaches a Lonely Light in the Dark

A splatter of stars glows faintly at almost 3 million light-years away in this new image from NASA’s Hubble Space Telescope. Known as the Tucana Dwarf for lying in the constellation Tucana, this dwarf galaxy contains a loose bundle of aging stars at the far edge of the Local Group, an aggregation of galaxies including […]

Hubble Finds Structure in an Unstructured Galaxy

This NASA Hubble Space Telescope image features the nearby dwarf irregular galaxy Leo A, located some 2.6 million light-years away. The relatively open distribution of stars in this diminutive galaxy allows light from distant background galaxies to shine through.

Hubble Peers Into the Center of a Star-forming Powerhouse

This view from NASA’s Hubble Space Telescope plunges into the center of spiral galaxy Messier 33 (M33), also known as the Triangulum Galaxy.  Located within the triangle-shaped constellation Triangulum and about half the size of our Milky Way galaxy, M33 is the third-largest member of our Local Group of galaxies after the Andromeda galaxy (M31) […]

Hubble Rings in a New Galactic View

The subject of this NASA/ESA Hubble Space Telescope image is situated in the Perseus Cluster, also known as Abell 426, 320 million light-years from Earth. It’s a barred spiral galaxy known as MCG+07-07-072, seen here among a number of photobombing stars that are much closer to Earth than it is. MCG+07-07-072 has quite an unusual shape for a […]

Hubble Spies a Diminutive Galaxy

This NASA/ESA Hubble Space Telescope image reveals the subtle glow of the galaxy named IC 3430, located 45 million light-years from Earth in the constellation Virgo. This dwarf elliptical galaxy is part of the Virgo cluster, a rich collection of galaxies both large and small, many of which are very similar in type to this […]
