Boomerang-like beams of light
Nov 21, 2023 (SPX)
"Imagine that you are throwing a tennis ball. The ball starts moving forward with positive momentum. If the ball doesn't hit an obstacle, you are unlikely to ex...
SUNY team finds alternative cosmic source of gold in published collaborative research
Nov 21, 2023 (SPX)
Neutron stars are the evolutionary end points of stars with a mass between 10 - 25 times that of the Sun. After the final explosion, the star leaves behind a co...
Webb reveals new features in heart of the Milky Way
Nov 21, 2023 (ESA)
Amid the estimated 500 000 stars in the image is a cluster of protostars - stars that are still forming and gaining mass - producing outflows that glow like a b...
Physicists answer question of Supergalactic Plane's absent spiral galaxies
Nov 21, 2023 (SPX)
The Supergalactic Plane is an enormous, flattened structure extending nearly a billion light years across in which our own Milky Way galaxy is embedded. While t...
Investigating the contribution of gamma-ray blazar flares to neutrino flux
Nov 21, 2023 (SPX)
Gamma-ray flares from blazars are thought to be the primary events behind neutrino detection in the sky. In 2017, the South Pole neutrino detector "IceCube" det...
ALMA demonstrates highest resolution yet
Nov 16, 2023 (SPX)
ALMA is a radio interferometric array telescope, in which individual antennas work together to observe a celestial object. ALMA's resolution, the ability to see...
With unprecedented flares, stellar corpse shows signs of life
Nov 16, 2023 (SPX)
The bright, brief flashes - as short as a few minutes in duration, and as powerful as the original explosion 100 days later - appeared in the aftermath of a rar...
IXPE untangles theories surrounding historic supernova remnant
Nov 16, 2023 (SPX)
"Magnetic fields are extremely difficult to measure, but IXPE provides an efficient way for us to probe them," said Dr. Ping Zhou, an astrophysicist at Nanjing ...
NASA telescope data becomes music you can play
Nov 16, 2023 (SPX)
Since 2020, the "sonification" project at NASA's Chandra X-ray Center has translated the digital data taken by telescopes into notes and sounds. This process al...
Astronomers baffled by repeat explosions 100 billion times the energy of the Sun
Nov 16, 2023 (SPX)
The report, published in Nature, describes a Luminous Fast Blue Optical Transient (LFBOT) monitored in a new way and shown to have unusual behaviour. LFBOTs are...
Webb observes the glowing embers of colliding neutron stars
Nov 16, 2023 (SPX)
About once per day, a brief flash of gamma radiation, the most energetic form of light, reaches Earth from the distant Universe. We have known these gamma-ray b...
Downloading NASA's dark matter data from above the clouds
Nov 16, 2023 (SPX)
In April, the Super Pressure Balloon Imaging Telescope (SuperBIT) was launched from Wanaka Airport, New Zealand, suspended under a helium-filled balloon the siz...
Deep learning speeds up galactic calculations
Nov 16, 2023 (SPX)
When you hear about deep learning, you might think of the latest app that sprung up this week to do something clever with images or generate humanlike text. Dee...
Blast from the past: Gamma-ray burst strikes Earth from distant exploding star
Nov 15, 2023 (ESA)
At 14:21 BST / 15:21 CEST on 9 October 2022, an extremely bright and long-lasting gamma-ray burst (GRB) was detected by many of the high-energy satellites in or...
Study finds strongest evidence yet for local sources of cosmic ray electrons
Nov 15, 2023 (SPX)
The study included more than seven million data points representing particles arriving at CALET's detector since 2015, and CALET's ability to detect electrons a...
Brightest flash ever disturbed Earth's atmosphere last year
Nov 14, 2023 (AFP)
