NASA telescopes find new clues about mysterious deep space signals
What's causing mysterious bursts of radio waves from deep space? Astronomers may be a step closer to providing one answer to that question. Two NASA X-ray telescopes recently observed one of such events—known as a fast radio burst—mere minutes be.....»»
CIS ESS Mobile offers visibility into blind spots on mobile devices
While most organizations focus cybersecurity efforts on fortifying their networks, the mobile devices connected to them often remain vulnerable. In addressing this gap, the Center for Internet Security (CIS) introduces CIS Endpoint Security Services.....»»
Clouds disappear quickly during a solar eclipse, shows study
Cumulus clouds over land start to disappear almost instantly during a partial solar eclipse. Until recently, satellite measurements during the eclipse resulted in dark spots in the cloud map, but researchers from TU Delft and KNMI were able to recove.....»»
Hubble spots a galaxy shrouded by stars
This NASA/ESA Hubble Space Telescope image shows a densely packed field of stars laid upon a background of dust, gas, and light from more distant celestial objects. There are so many stars in this image's field of view that it may be a little tricky.....»»
Chinese astronomers find radio pulsar in a supernova remnant
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers from the Nanjing University in China and elsewhere, have detected a radio pulsar in a supernova remnant known as CTB 87. The finding is reported in a paper published.....»»
Researchers discover cosmic dust storms from Type 1a supernova
Cosmic dust—like dust on Earth—comprises groupings of molecules that have condensed and stuck together in a grain. But the exact nature of dust creation in the universe has long been a mystery. Now, however, an international team of astronomers f.....»»
Quantum simulation with ultracold fermions unveils pairing pseudogap
A research team has, for the first time, observed and quantitatively characterized the many-body pairing pseudogap in unitary Fermi gases. This achievement, pursued by the ultracold atomic community for nearly two decades, resolves longstanding debat.....»»
Gamma-ray bursts: Harvesting knowledge from the universe"s most powerful explosions
The most powerful events in the known universe—gamma-ray bursts (GRBs)—are short-lived outbursts of the highest-energy light. They can erupt with a quintillion (a 10 followed by 18 zeros) times the luminosity of our sun. Now thought to announce t.....»»
New method spots cosmic threats by extracting 3D direction of plasma ejections from sun"s 2D ultraviolet images
A team of scientists has unveiled a novel method for the early estimation of coronal mass ejection (CME) direction in 3D space. The groundbreaking technique, named DIRECD—"Dimming InfeRred Estimate of CME Direction"—will provide crucial data to m.....»»
Machine learning techniques enhance the discovery of excited nuclear levels in sulfur-38
Fixed numbers of protons and neutrons—the building blocks of nuclei—can rearrange themselves within a single nucleus. The products of this reshuffling include electromagnetic (gamma ray) transitions. These transitions connect excited energy level.....»»
Betelgeuse before, during and after the Great Dimming
When a prominent star in the night sky suddenly dims, it generates a lot of interest. That's what happened with the red supergiant star Betelgeuse between November 2019 and May 2020. Betelgeuse will eventually explode as a supernova. Was the dimming.....»»
