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 […]

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.

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 […]

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 […]

Scientists and engineers are ready to fly an infrared mission called EXCITE (EXoplanet Climate Infrared TElescope) to the edge of space.  EXCITE is designed to study atmospheres around exoplanets, or worlds beyond our solar system, during circumpolar long-duration scientific balloon flights.

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) […]

This NASA Hubble Space Telescope image captures the dwarf irregular galaxy UGC 4879 or VV124. As this image illustrates, Hubble’s high resolution can detect individual stars, even in the densest parts of the galaxy. This allows astronomers to better determine the galaxy’s distance, and the composition and age of its stars. UGC 4879 is an […]
