Buckle Up: NASA-Funded Study Explores Turbulence in Molecular Clouds

On an airplane, motions of the air on both small and large scales contribute to turbulence, which may result in a bumpy flight. Turbulence on a much larger scale is important to how stars form in giant molecular clouds that permeate the Milky Way. In a new NASA-funded study in the journal Science Advances, scientists […]

Planets Beware: NASA Unburies Danger Zones of Star Cluster

Most stars form in collections, called clusters or associations, that include very massive stars. These giant stars send out large amounts of high-energy radiation, which can disrupt relatively fragile disks of dust and gas that are in the process of coalescing to form new planets. A team of astronomers used NASA’s Chandra X-ray Observatory, in […]

Hubble Captures Stellar Nurseries in a Majestic Spiral

This image from the NASA/ESA Hubble Space Telescope features the spiral galaxy IC 1954, located 45 million light-years from Earth in the constellation Horologium. It sports a glowing bar in its core, majestically winding spiral arms, and clouds of dark dust across it. Numerous glowing, pink spots across the disc of the galaxy are H-alpha […]

NASA’s Hubble Finds that a Black Hole Beam Promotes Stellar Eruptions

In a surprise finding, astronomers using NASA’s Hubble Space Telescope have discovered that the blowtorch-like jet from a supermassive black hole at the core of a huge galaxy seems to cause stars to erupt along its trajectory. The stars, called novae, are not caught inside the jet, but apparently in a dangerous neighborhood nearby. The […]

In Odd Galaxy, NASA’s Webb Finds Potential Missing Link to First Stars

Looking deep into the early universe with NASA’s James Webb Space Telescope, astronomers have found something unprecedented: a galaxy with an odd light signature, which they attribute to its gas outshining its stars.

NASA’s Webb Peers into the Extreme Outer Galaxy

Astronomers have directed NASA’s James Webb Space Telescope to examine the outskirts of our Milky Way galaxy. Scientists call this region the Extreme Outer Galaxy due to its location more than 58,000 light-years away from the Galactic Center.

Hubble Zooms into the Rosy Tendrils of Andromeda

Clusters of stars set the interstellar medium ablaze in the Andromeda Galaxy about 2.5 million light-years away. Also known as M31, Andromeda is the Milky Way’s closest major galaxy. It measures approximately 152,000 light-years across and, with almost the same mass as our home galaxy, is headed for a collision with the Milky Way in […]

NASA’s Roman Space Telescope to Investigate Galactic Fossils

The universe is a dynamic, ever-changing place where galaxies are dancing, merging together, and shifting appearance. Unfortunately, because these changes take millions or billions of years, telescopes can only provide snapshots, squeezed into a human lifetime. However, galaxies leave behind clues to their history and how they came to be.

Hubble Observes An Oddly Organized Satellite

Andromeda III is one of at least 13 dwarf satellite galaxies in orbit around the Andromeda galaxy, or Messier 31, the Milky Way’s closest grand spiral galactic neighbor. Andromeda III is a faint, spheroidal collection of old, reddish stars that appears devoid of new star formation and younger stars. In fact, Andromeda III seems to […]

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 […]
