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.....»»
Zombie star’s strange behavior ascribed to what it’s eating
Neutron star winds, an accretion disk, and jets combine for complex interactions. Enlarge / Pulsars are spinning neutron stars, the relics of massive stars gone supernova. (credit: NASA's Goddard Space Flight Center) So.....»»
Astrophysicists determine how to find a supernova
The probability of detecting a supernova associated with a gamma-ray burst is currently 0.00346%. A network of several telescopes in different geographical coordinates, checking data in different photometric filters, analyzing images and taking into.....»»
Hubble finds bizarre explosion in unexpected place
A very rare, strange burst of extraordinarily bright light in the universe just got even stranger—thanks to the eagle-eye of the NASA/ESA Hubble Space Telescope. The phenomenon, called a Luminous Fast Blue Optical Transient (LFBOT), flashed onto th.....»»
Scientists discover the highest energy gamma-rays ever from a pulsar
Scientists using the H.E.S.S. observatory in Namibia have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about 10 trillion times the energy of visib.....»»
At least 10 dead, 102 missing in India glacial lake burst
Indian rescue teams searched on Thursday for 102 people missing after a devastating flash flood triggered by a high-altitude glacial lake burst killed at least 10, officials said......»»
Study identifies trend toward larger and fewer eyespot patterns on butterflies
Eye spots, color patterns that resemble the eyes of vertebrates, on butterfly wings are common in nature. A research team involving the Leibniz Institute for the Analysis of Biodiversity Change (LIB) and researchers in Mexico, Brazil and the U.S., ha.....»»
Undergraduate researcher discovers unexpected diversity in key river microorganisms
Once a week for the past year, Kylee Brevick could be found at two particular spots on the Willamette and Columbia rivers, taking samples of water for testing. The undergraduate biochemistry major (and environmental science minor) was undertaking an.....»»
What"s the link between gamma ray bursts and supernovae? It might be binary stars
Gamma-ray bursts (GRBs) are some of the most violent events in the universe. Some have a power output equivalent to all of the other stars in the observable universe, at least in the spectrum of gamma rays. But we know very little about them. A new p.....»»
Ascertaining distances for supernovae that struck the Earth 3 million and 7 million years ago
A study, released on the pre-print server arXiv, examines how the Earth was hit by blasts from supernovae (plural form of supernova (SN)) that occurred 3 million years ago (Mya) and 7 Mya with the goal of ascertaining the distances of where these bla.....»»
Observations explore the properties of Type Ic supernova SN 2022jli
An international team of astronomers has performed multi-wavelength photometric and spectroscopic observations of a recently discovered Type Ic supernova known as SN 2022jli. Results of the observational campaign, published September 22 on the pre-pr.....»»
Hubble investigates the gorgeous remnants of a supernova
Scientists are using data from Hubble data of the famous Cygnus Loop supernova remnant to study how these remnants change over time......»»
Saturday Citations: Volcano vs. asteroid; NASA"s supernova time lapse; immortal chemicals
This week, we're highlighting a study involving toxic chemical contaminants, and just for fun, a second study involving other toxic chemical contaminants. But NASA made a cool time-lapse video using the good old Hubble space telescope, and a group of.....»»

Living on the edge: Supernova bubble expands in new Hubble time-lapse movie
Though a doomed star exploded some 20,000 years ago, its tattered remnants continue racing into space at breakneck speeds—and NASA's Hubble Space Telescope has caught the action......»»
Extreme weight loss: Star sheds unexpected amounts of mass just before going supernova
A newly discovered nearby supernova whose star ejected up to a full solar mass of material in the year prior to its explosion is challenging the standard theory of stellar evolution. The new observations are giving astronomers insight into what happe.....»»
Sperm swimming is caused by the same patterns that are believed to dictate zebra stripes
Patterns of chemical interactions are thought to create patterns in nature such as stripes and spots. A new study shows that the mathematical basis of these patterns also governs how sperm tail moves......»»
