Fermi spots a supernova"s "fizzled" gamma-ray burst
On Aug. 26, 2020, NASA's Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned out to be one for the record.....»»
Deep mantle krypton reveals Earth"s outer solar system ancestry
Krypton from the Earth's mantle, collected from geologic hot spots in Iceland and the Galapagos Islands, reveals a clearer picture of how our planet formed, according to new research from the University of California, Davis......»»
A young, sun-like star may hold warnings for life on Earth
Astronomers spying on a stellar system located dozens of lightyears from Earth have, for the first time, observed a troubling fireworks show: A star, named EK Draconis, ejected a massive burst of energy and charged particles much more powerful than a.....»»
Researchers capture the fastest optical flash emitted from a newborn supernova
A team of astronomers has discovered the fastest optical flash of a Type Ia supernova, and reports a study in Astrophysical Journal Letters published on December 8......»»
Star"s self-destruction is shown in 3D, revealing new details
A 1,000-year-old supernova has been captured in 3D images that reveal yet unseen details of the elements that are ejected when a star explodes. Analysis of data from the Multi-Unit Spectroscopic Explorer (MUSE) and X-shooter at the European Southern.....»»
Mysterious metal depositions were "the most ordinary thing in the world"
In Bronze Age Europe, many bronze objects such as axes, swords and jewels were deliberately left at specific spots in the landscape. Ph.D. research by Leiden archaeologist Marieke Visser shows that these practices were expressions of people's relatio.....»»

Hubble spots a swift stellar jet in Running Man Nebula
A jet from a newly formed star flares into the shining depths of reflection nebula NGC 1977 in this Hubble image. The jet (the orange object at the bottom center of the image) is being emitted by the young star Parengo 2042, which is embedded in a di.....»»
Image: Hubble spots swirls of dust in the flame Nebula
The Flame Nebula, also called NGC 2024, is a large star-forming region in the constellation Orion that lies about 1,400 light-years from Earth. It's a portion of the Orion Molecular Cloud Complex, which includes such famous nebulae as the Horsehead N.....»»
If alien probes are already in the solar system, maybe we could detect them calling home
It's been 70 years since physicist Enrico Fermi asked his famous question: "Where is everybody?" And yet, the tyranny of the Fermi Paradox is still with us and will continue to be until definitive evidence of extraterrestrial intelligence (ETI) is fo.....»»
The host galaxy of a fast radio burst
Fast radio bursts (FRBs) are bright pulses of emission at radio wavelengths (seen mostly at wavelengths of tens of centimeters) whose physical mechanism(s) are mysterious. The bursts last between hundredths of a millisecond to a few milliseconds, and.....»»
Energizer atoms: Physicists find new way to keep atoms excited
JILA researchers have tricked nature by tuning a dense quantum gas of atoms to make a congested "Fermi sea," thus keeping atoms in a high-energy state, or excited, for about 10% longer than usual by delaying their normal return to the lowest-energy s.....»»
Bubbling up: Previously hidden environmental impact of bursting bubbles exposed in new study
Bubbles are common in nature and can form when ocean waves break and when raindrops impact surfaces. When bubbles burst, they send tiny jets of water and other materials into the air. A new study from the University of Illinois Urbana-Champaign exami.....»»
Tesla driver raced at high speed through yellow light before Florida crash
The driver of a Tesla that burst into flames after striking a tree last September in Florida was racing at several times the speed limit, investigators said......»»
Data from the Fermi Large Area Telescope suggests there is a particle accelerator in the galactic center
A team of researchers at the Chinese Academy of Sciences has found evidence of a powerful particle accelerator in the galactic center. In their paper published in the journal Nature Communications, the group describes their analysis of data obtained.....»»
Astronaut training in the land of volcanoes
A team of astronauts, engineers and geologists is traveling to Spain's Canary Islands, one of Europe's volcanic hot spots, to learn how to best explore the Moon and Mars during ESA's Pangaea geological training course......»»
Discovery of segmented Fermi surface induced by Cooper pair momentum on a hybrid material platform
