New exoplanet detected with the ESPRESSO spectrograph
Using the Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations (ESPRESSO), astronomers from Switzerland and Austria have discovered a new alien world. The newfound exoplanet orbits a nearby M dwarf star and is at least four.....»»
Possible hints of life found on distant planet. How excited should we be?
Data from the James Webb Space Telescope (JWST) has shown that an exoplanet around a star in the constellation Leo has some of the chemical markers that, on Earth, are associated with living organisms. But these are vague indications. So how likely i.....»»

Two new rotating radio transients discovered
Using the Large Phased Array (LPA) radio telescope of the Lebedev Physical Institute (LPI) in Pushchino, Russia, astronomers have detected two new rotating radio transients (RRATS). The finding is reported in a research paper published September 2 on.....»»
JWST accidentally discovers 21 brown dwarfs
When you launch humanity's most powerful telescope, you expect results. The JWST has delivered excellent results by detecting ancient galaxies, identifying chemicals in exoplanet atmospheres, and peering into star-forming regions with more detail and.....»»
Two large cold fronts detected in the galaxy cluster Abell 3558
Astronomers from the University of Alabama in Huntsville have investigated the galaxy cluster Abell 3558 using ESA's XMM-Newton spacecraft. In their results, they detected two large-scale sloshing cold fronts in the outskirts of this cluster. The fin.....»»
New insights into neutrino interactions
Research at Hokkaido University has revealed that elusive particles called neutrinos can interact with photons, the fundamental particles of light and other electromagnetic radiation, in ways not previously detected. The findings from Kenzo Ishikawa,.....»»

Astronomers discover new massive quiescent galaxy
Astronomers report the discovery of a new massive and quiescent galaxy at a high redshift. The galaxy, which received designation COSMOS-1047519, was detected using the Keck I telescope. The finding was detailed in a paper published August 29 on the.....»»
If Earth were an exoplanet, JWST would know there"s an intelligent civilization here
If we're going to look for life on other worlds, why not start with the one planet we know has life? Earth's atmosphere is rich with oxygen and molecules such as methane, which strongly suggest the presence of life. It also has traces of molecules su.....»»
Saturday Citations: Ancient corvids, tetraquarks, and researchers who aren"t bored hearing about your dreams
This week, researchers reported on two-dimensional gold sheets, a tidy little meson made of four quarks (and its buddy!) and a big and almost unimaginably dense exoplanet with an exciting backstory......»»
Scientists detect and validate the longest-period exoplanets found with TESS
Scientists from The University of New Mexico (UNM), and Massachusetts Institute of Technology (MIT) have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and be.....»»
Dense Neptune-sized exoplanet discovered with TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new massive and dense exoplanet. The newfound alien world, designated TOI-332 b, is one of the densest Neptune-sized planets known to dat.....»»
India"s moon rover confirms sulfur and detects several other elements near the lunar south pole
India's moon rover confirmed the presence of sulfur and detected several other elements near the lunar south pole as it searches for signs of frozen water nearly a week after its historic moon landing, India's space agency said Tuesday......»»
"Thermometer" molecule confirmed on exoplanet WASP-31b
Chromium hydride (CrH), a molecule that's relatively rare and particularly sensitive to temperature, is useful as a "thermometer for stars," according to astronomer Laura Flagg, because it's abundant only in a narrow range between 1,200–2,000 degre.....»»
New supernova remnant detected with ASKAP
Using the Australian Square Kilometer Array Pathfinder (ASKAP), an international team of astronomers has serendipitously detected a new Galactic supernova remnant (SNR), which received designation SNR G288.8–6.3. The finding was reported in a paper.....»»
TESS has found thousands of possible exoplanets: Which ones should JWST study?
There are more than 5,000 confirmed exoplanets in our galaxy. That number is going to rise significantly in the next decade. The Transiting Exoplanet Survey Satellite (TESS) has already cataloged more than 4,000 candidate exoplanets, and the PLAnetar.....»»
Ransomware dwell time hits new low
Median attacker dwell time—the time from when an attack starts to when it’s detected—shrunk from 10 to eight days for all attacks, and to five days for ransomware attacks during the first half of 2023, according to Sophos. In 2022, the median d.....»»
