Black Hole Jet Stumbles Into Something in the Dark

Even matter ejected by black holes can run into objects in the dark. Using NASA’s Chandra X-ray Observatory, astronomers have found an unusual mark from a giant black hole’s powerful jet striking an unidentified object in its path. The discovery was made in a galaxy called Centaurus A (Cen A), located about 12 million light-years […]

NASA’s Swift Studies Gas-Churning Monster Black Holes

Scientists using observations from NASA’s Neil Gehrels Swift Observatory have discovered, for the first time, the signal from a pair of monster black holes disrupting a cloud of gas in the center of a galaxy. “It’s a very weird event, called AT 2021hdr, that keeps recurring every few months,” said Lorena Hernández-García, an astrophysicist at […]

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 […]

NASA Reveals Prototype Telescope for Gravitational Wave Observatory

NASA has revealed the first look at a full-scale prototype for six telescopes that will enable, in the next decade, the space-based detection of gravitational waves — ripples in space-time caused by merging black holes and other cosmic sources.

NASA’s Webb Provides Another Look Into Galactic Collisions

Smile for the camera! An interaction between an elliptical galaxy and a spiral galaxy, collectively known as Arp 107, seems to have given the spiral a happier outlook thanks to the two bright “eyes” and the wide semicircular “smile.” The region has been observed before in infrared by NASA’s Spitzer Space Telescope in 2005, however […]

NASA’s Webb Reveals Distorted Galaxy Forming Cosmic Question Mark

It’s 7 billion years ago, and the universe’s heyday of star formation is beginning to slow. What might our Milky Way galaxy have looked like at that time? Astronomers using NASA’s James Webb Space Telescope have found clues in the form of a cosmic question mark, the result of a rare alignment across light-years of […]

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.

NASA’s Fermi Finds New Feature in Brightest Gamma-Ray Burst Yet Seen

In October 2022, astronomers were stunned by what was quickly dubbed the BOAT — the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA’s Fermi Gamma-ray Space Telescope reveals a feature never seen before.

How NASA’s Roman Space Telescope Will Illuminate Cosmic Dawn

Today, enormous stretches of space are crystal clear, but that wasn’t always the case. During its infancy, the universe was filled with a “fog” that made it opaque, cloaking the first stars and galaxies. NASA’s upcoming Nancy Grace Roman Space Telescope will probe the universe’s subsequent transition to the brilliant starscape we see today –– […]

Two Years Since Webb’s First Images: Celebrating with the Penguin and the Egg

To celebrate the second science anniversary of NASA’s James Webb Space Telescope, the team has released a near- and mid-infrared image on July 12, 2024, of two interacting galaxies: The Penguin and the Egg. Webb specializes in capturing infrared light – which is beyond what our own eyes can see – allowing us to view and […]
