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.....»»
How animals get their stripes and spots
Nature has no shortage of patterns, from spots on leopards to stripes on zebras and hexagons on boxfish. But a full explanation for how these patterns form has remained elusive......»»
Supermassive black hole found only half a billion years after Big Bang
There just isn't time for something that big to grow from a supernova remnant. Enlarge / Inset shows the JWST image of the galaxy in infrared, along with the X-rays from the black hole seen by the Chandra. While the X-ray source.....»»
Half of the mass of an early galaxy is in its central black hole

Searching for the supernova neutrino background to the universe
It's a sobering statement that stars like the sun, more accurately all stars will die eventually—yes, even the sun. Don't panic, though, we still have a good few billion years to go so you will get to the end of this article. The more massive stars.....»»
Ferroelectric modulation of Fermi level of graphene oxide to enhance SERS response
Surface-enhanced Raman scattering (SERS) is a powerful fingerprint analysis and detection technique that plays an important role in the fields of food safety, environmental protection, bio-imaging and hazardous substance identification. Electromagnet.....»»
Research explores the properties of supernova remnant 1E 0102.2–7219
Using the Australia Telescope Compact Array (ATCA) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has observed a supernova remnant known as 1E 0102.2–7219. Results of the study, presented October 2.....»»
NASA rocket to see sizzling edge of star-forming supernova
A new sounding rocket mission is headed to space to understand how explosive stellar deaths lay the groundwork for new star systems. The Integral Field Ultraviolet Spectroscopic Experiment, or INFUSE, sounding rocket mission, will launch from the Whi.....»»
How close is too close to a kilonova?
Cataclysmic events happen in the universe all the time. Black hole mergers, supernovae, gamma-ray bursts, and a whole host of others. Most of them happen in distant galaxies, so they pose no threat to us. But there are a few that could affect life on.....»»
JWST looks at the debris disk around a white dwarf
Debris disks are quite common in the universe. Young stars have protoplanetary disks from which planets form. Black holes have accretion disks that are the source of the galactic jets. Supernova remnants can form a disk around neutron stars. So what.....»»
"Mind-blowing": Astronomers spot most distant radio burst yet
Eight billion years ago, something happened in a distant galaxy that sent an incredibly powerful blast of radio waves hurtling through the universe......»»

Astronomers detect most distant fast radio burst to date
An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory's (ESO) Very Larg.....»»
Astronomers comb telescope archive and find microsecond-duration burst
An international team of researchers led by Dutch Ph.D. candidate Mark Snelders (ASTRON and University of Amsterdam) has discovered radio pulses from the distant universe that last only millionths of a second. They found these microsecond bursts afte.....»»
Astronomers report discovery of the closest ultrastripped supernova: SN 2021agco in UGC 3855
Astronomers report the discovery of a new ultrastripped supernova in the galaxy UGC 3855. The supernova was detected using the Half Meter Telescope (HMT) at the Xingming Observatory in China. The finding was detailed in a paper published October 7 on.....»»
Scientists present the first set of global maps showing geographic patterns of beta-diversity in flowering plants
Beta-diversity serves as a crucial metric for gauging shifts in species composition over spatial or temporal scales, bridging the spectrum between localized (alpha) and broader regional (gamma) diversity. In the fields of ecology, biogeography and co.....»»
First supernova detected, confirmed, classified and shared by AI
A fully automated process, including a brand-new artificial intelligence (AI) tool, has successfully detected, identified and classified its first supernova......»»
