SuperBIT: A low-cost balloon-borne telescope to rival Hubble
Jul 21, 2021 (SPX)
Light from a distant galaxy can travel for billions of years to reach our telescopes. In the final fraction of a second, the light has to pass through the Earth...
A bug's life: Millimeter-tall mountains on neutron stars
Jul 20, 2021 (SPX)
Neutron stars are some of the densest objects in the Universe: they weigh about as much as the Sun, yet measure only around 10km across, similar in size to a la...
Cosmic rays help supernovae explosions pack a bigger punch
Jul 20, 2021 (SPX)
When supernovae explode, they emit light and billions of particles into space. While the light can freely reach us, particles become trapped in spiral loops by ...
NASA returns Hubble Space Telescope to science operations
Jul 19, 2021 (SPX)
"Hubble is an icon, giving us incredible insight into the cosmos over the past three decades," said NASA Administrator Bill Nelson. "I'm proud of the Hubble tea...
NASA identifies computer problem on Hubble, says fix will take a few days
Jul 15, 2021 (UPI)
The agency said Thursday it would start a process to switch to a backup system, and that the telescope could be back to normal operations within a few days. The...
A star in a distant galaxy blew up in a powerful explosion, solving an astronomical mystery
Jul 15, 2021 (SPX)
A supernova is the explosion of a star following a sudden imbalance between two opposing forces that shaped the star throughout its life. Gravity tries to contr...
Operations underway to restore payload computer on Hubble Space Telescope
Jul 15, 2021 (SPX)
The payload computer resides in the Science Instrument Command and Data Handling (SI C&DH) unit. It controls, coordinates, and monitors Hubble's science instrum...
Galactic gamma ray bursts predicted last year show up right on schedule
Jul 14, 2021 (SPX)
A team of astrophysicists has now found another peculiarity of magnetars: They can emit bursts of low energy gamma rays in a pattern never before seen in any ot...
NASA grapples with Hubble Telescope's most serious problem in years
Jul 12, 2021 (UPI)
Hubble stopped working suddenly June 13 while astronomers were using the 31-year-old telescope to examine pulsating stars 200 million miles away. NASA is trying...
What to know about NASA's $10B James Webb Space Telescope
Jul 12, 2021 (UPI)
The images, released July 12, show infrared images from deep in the universe. Here's a closer look at the history-making telescope, the largest and most powerfu...

Jul 12, 2021 (UPI)
The space agency unveiled the collection of five images from the $10 billion telescope during an event late Tuesday morning at the Goddard Space Flight Center i...
Seeing some cosmic x-ray emitters might be a matter of perspective
Jul 12, 2021 (JPL)
New data from NASA's NuSTAR space observatory indicates that this phenomenon holds true for some of the most prominent X-ray emitters in the local universe: ult...
New radio receiver opens wider window to radio universe
Jul 12, 2021 (SPX)
Interstellar molecular clouds of gas and dust provide the material for stars and planets. Each type of molecule emits radio waves at characteristic frequencies ...
Thousands of galaxies classified in a blink of an eye
Jul 08, 2021 (SPX)
In new researchm astrophysicists from Australia have used machine learning to speed up a process that is often done manually by astronomers and citizen scientis...
Satellite galaxies can carry on forming stars when they pass close to their parent galaxies
Jul 07, 2021 (SPX)
Using sophisticated simulations of the whole of the Local Group of galaxies, including the Milky Way, the Andromeda galaxy and their respective satellite galaxi...
SwRI-led team addresses mystery of heavy elements in galactic cosmic rays
Jul 07, 2021 (SPX)
The supernova explosion of a dying star creates massive shockwaves that propagate through the surrounding space, accelerating ions in their path to very high en...
Kepler telescope glimpses population of free-floating planets
Jul 07, 2021 (SPX)
The study, led by Iain McDonald of the University of Manchester, UK, (now based at the Open University, UK) used data obtained in 2016 during the K2 mission pha...
A meteorite witness to the solar system's birth
Jul 07, 2021 (SPX)
