Origins of fast radio bursts come into focus through polarized light
What scientists previously thought about where Fast Radio Bursts (FRBs) come from is just the tip of the iceberg, according to new research led by astronomers at the University of Toronto. The mysteries of the millisecond-long cosmic explosions are u.....»»
First map of outflows from nearby quasar I Zwicky 1
SRON astronomers have for the first time mapped the outflows from one of the closest quasars to Earth. Quasars are bright cores of galaxies powered by the supermassive black hole in their center. The team has probed gas outflows in I Zwicky 1, a clos.....»»
Euclid is finding free floating planets in Orion, too
There are likely millions of "rogue" or free-floating planets (FFPs) spread through the galaxy. These planets, which aren't big enough to become stars but also aren't beholden to a star's gravity, are some of the hardest objects for astronomers to sp.....»»
Star cluster shines in new look from NASA"s Chandra
Westerlund 1 is the biggest and closest "super" star cluster to Earth. New data from NASA's Chandra X-ray Observatory, in combination with other NASA telescopes, is helping astronomers delve deeper into this galactic factory where stars are vigorousl.....»»
Astronomers observe giant outburst of a distant X-ray binary
Using the Neutron Star Interior Composition Explorer (NICER) onboard the International Space Station, astronomers have observed a distant X-ray binary known as EXO 2030+375. The observational campaign allowed them to explore a giant outburst that occ.....»»
NASA, global astronomers await rare nova explosion
Around the world this summer, professional and amateur astronomers alike will be fixed on one small constellation deep in the night sky. But it's not the seven stars of Corona Borealis, the "Northern Crown," that have sparked such fascination......»»
Reconnaissance of potentially habitable worlds with Webb
Exoplanets are common in our galaxy, and some even orbit in the so-called habitable zone of their star. NASA's James Webb Space Telescope has been busy observing a few of these small, potentially habitable planets, and astronomers are now hard at wor.....»»
Astronomers investigate giant molecular clouds in the galaxy NGC 613
Using the Atacama Large Millimeter/sub-millimeter Array (ALMA), an international team of astronomers has performed high-resolution observations of a nearby galaxy known as NGC 613. Results of the observational campaign, published May 30 on the prepri.....»»
Researchers develop instrument to measure lava viscosity in the field
Millions of people live near active volcanoes that are constantly monitored for signs of an impending eruption. When one occurs, scientists and governments rely on data to estimate the extent of the possible damage, informing evacuation plans and dis.....»»
Researcher introduces strategies to sustain aesthetics and performance in anthropogenic landscapes
Entering the Anthropocene, humans are confronted with a grim yet peculiar state of increasing natural landscapes inching closer to extinction. Notably, the Aral Sea retains a mere 10% of its original volume, highlighting the urgency of the situation......»»
TOI-1685 b is a hot and rocky super-Earth exoplanet, observations find
An international team of astronomers has performed follow-up observations of a nearby alien world known as TOI-1685 b. Results of the observations, published May 21 on the pre-print server arXiv, indicate that TOI-1685 b is a hot and rocky alien worl.....»»
Study investigates a massive "spider" pulsar
Astronomers from the Stanford University in California have performed joint X-ray and optical observations of a massive "spider" pulsar designated PSR J2215+5135. Results of the observational campaign, presented in a paper published May 22 on the pre.....»»
A new deep-learning algorithm can find Earth 2.0
How can machine learning help astronomers find Earth-like exoplanets? This is what a new study hopes to address as a team of international researchers investigated how a novel neural network-based algorithm could be used to detect Earth-like exoplane.....»»
X-ray binary Swift J1727.8-1613 has a large relativistic jet, observations show
Using the Very Long Baseline Array (VLBA) and the Long Baseline Array (LBA), astronomers have observed a black hole low-mass X-ray binary known as Swift J1727.8-1613. As a result, they found that the system hosts a highly extended and bright relativi.....»»
Lava continues to flow from Iceland volcano but not at powerful level as eruption
Lava continued to spurt from a volcano in southwestern Iceland on Thursday but the activity had calmed significantly from when it erupted a day earlier......»»
Tonga"s volcanic eruption could cause unusual weather for the rest of the decade, new study shows
Hunga Tonga-Hunga Ha'apai (Hunga Tonga for short) erupted on January 15 2022 in the Pacific Kingdom of Tonga. It created a tsunami which triggered warnings across the entire Pacific basin, and sent sound waves around the globe multiple times......»»
Astronomers help find most distant galaxy using James Webb Space Telescope
An international team of astronomers today announced the discovery of the two earliest and most distant galaxies ever seen, dating back to only 300 million years after the Big Bang. These results, using NASA's James Webb Space Telescope (JWST), mark.....»»
Black holes are firing beams of particles, changing targets over time
Black holes seem to provide endless fascination to astronomers. This is at least partly due to the extreme physics that takes place in and around them, but sometimes, it might harken back to cultural touchpoints that made them interested in astronomy.....»»
TESS finds intriguing world sized between Earth and Venus
Using observations by NASA's TESS (Transiting Exoplanet Survey Satellite) and many other facilities, two international teams of astronomers have discovered a planet between the sizes of Earth and Venus only 40 light-years away. Multiple factors make.....»»
Dyson spheres: Astronomers report potential candidates for alien structures, and evidence against their existence
There are three ways to look for evidence of alien technological civilizations. One is to look out for deliberate attempts by them to communicate their existence, for example, through radio broadcasts. Another is to look for evidence of them visiting.....»»
