For its next trick, Gaia could help detect background gravitational waves in the universe
Ripples in a pond can be captivating on a nice sunny day as can ripples in the very fabric of space, although the latter are a little harder to observe. Using the highly tuned Gaia probe, a team of astronomers proposes in a paper posted to arXiv prep.....»»

"It"s unbearable": heat waves scorch southern and eastern Europe
Unrelenting heat is blanketing swathes of southern and eastern Europe, with dozens of cities on red alert as scorching temperatures fuel wildfires, strain power grids, and make daily life unbearable......»»
Tool predicts rogue waves up to five minutes in advance
A new tool that can be used to predict the emergence of unusually large and unpredictable waves at sea—known as rogue waves—up to five minutes into the future is presented in a study published in Scientific Reports. The authors suggest that the t.....»»
FIN7 sells improved EDR killer tool
The cybercrime-focused enterprise known as FIN7 (aka the Carbanak group) has come up with yet another trick to assure the effectiveness of its “EDR killer” tool, dubbed AvNeutralizer (i.e., AuKill) by researchers. By leveraging Windows.....»»
Observations detect a nearby hypervelocity stellar/substellar object
Using the Keck II telescope, astronomers have detected an object that may be a brown dwarf or a low-mass star, exhibiting a very high radial velocity. The object, designated CWISE J124909.08+362116.0 is located some 400 light years away. The finding.....»»
Researchers identify structural characteristics of newly emerged SARS-CoV-2 variants
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to adapt to the herd immunity background and evolve into numerous sub-variants......»»
New Jersey salt marsh sediments offer evidence of hurricanes back to the 1500s
A Rutgers University-New Brunswick-led research team employing an emerging technique to detect signs of past hurricanes in coastal sediments has found evidence of storms dating back more than 400 years. In doing so, they have confirmed an approach th.....»»
Double trouble: Gaia hit by micrometeoroid and solar storm
Launched in December 2013, ESA's Gaia spacecraft is on a mission to map the locations and motions of more than a billion stars in the Milky Way with extreme precision......»»
Attributing Canada"s June heat wave to climate change is an important step in adapting to a warmer world
This June saw major heat waves across Canada with peak temperatures—measured over a three-day period—of 7.4°C in eastern Ontario, 10.7°C in southern Québec, 7.2°C in northern Québec and 10.6°C in Atlantic Canada. On June 19, more than 100 l.....»»
Astronomers detect dozens of new pulsating white dwarfs
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected 32 new bright pulsating DA white dwarfs of the ZZ Ceti subclass. The finding was reported in a research paper published July 9 on the pre-print server arXiv......»»
Astronomers discover what may be 21 neutron stars orbiting sun-like stars
Most stars in our universe come in pairs. While our own sun is a loner, many stars like our sun orbit similar stars, while a host of other exotic pairings between stars and cosmic orbs pepper the universe. Black holes, for example, are often found or.....»»
iOS 18: How to change Lock Screen controls on iPhone
iOS 18 offers more customization than ever and one of the new options is the ability to change Lock Screen controls on iPhone. There are over 50 options to replace the Flashlight and Camera buttons. But one trick gives you access to almost unlimited.....»»
Observatory gears up to detect thousands of elusive brown dwarfs, unlocking Milky Way mysteries
One could argue that brown dwarfs don't get the love they deserve. Sometimes referred to as "failed stars," they don't have enough mass to sustain nuclear fusion, which powers all stars, including our sun. But they are also too big to be considered p.....»»
Surprising ring sheds light on galaxy formation
The question of what triggers the extremely rapid star formation within Hyper Luminous Infrared Galaxies (HyLIRGs), as yet unknown, is of much interest to guide our understanding of the formation and evolution of galaxies in the universe. A new photo.....»»
How astronomers are using pulsars to observe evidence of dark matter
Tantalizing evidence of potential dark matter objects has been detected with the help of the universe's "timekeepers." These pulsars—neutron stars which rotate and emit lighthouse-like beams of radio waves that rapidly sweep through space—were us.....»»
Amid a sweltering summer, a new study finds street trees thrive in NYC
So far this summer, New York City—like much of the country—has clocked more than 11 90-plus degree days. In addition to the increasing frequency of extreme heat waves, if it seems hotter in the city than in other environments, it typically is......»»
Supermassive black holes have masses of more than a million suns—but their growth has slowed as the universe has aged
Black holes are remarkable astronomical objects with gravity so strong that nothing, not even light, can escape them. The most gigantic ones, known as "supermassive" black holes, can weigh millions to billions times the mass of the sun......»»
