Astronomers scrutinize scorching-hot exoplanet
An international team led by Stefan Pelletier, a Ph.D. student at Université de Montréal's Trottier Institute for Research on Exoplanets have made a detailed study of the extremely hot giant exoplanet WASP-76 b......»»
Webb investigates eternal sunrises, sunsets on distant world
Researchers using the James Webb Space Telescope have finally confirmed what models have previously predicted: An exoplanet has differences between its eternal morning and eternal evening atmosphere. WASP-39 b, a giant planet with a diameter 1.3 time.....»»
Scorching storms on distant worlds revealed in new detail
Astronomers have created the most detailed weather report so far for two distant worlds beyond our own solar system. The international study—the first of its kind—reveals the extreme atmospheric conditions on the celestial objects, which are swat.....»»
New low-mass galaxy discovered
Astronomers report the discovery of a new galaxy in the constellation Corvus. The newfound galaxy, which received designation Corvus A, has a relatively low mass, is gas-rich and isolated. The discovery was presented in a research paper published Jul.....»»
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.....»»
Nearby exoplanet could be first known ocean world: Webb telescope
A planet relatively close to Earth could be the first ever detected with a potentially life-sustaining liquid ocean outside our Solar System, according to scientists using the James Webb space telescope......»»
Saturday Citations: The first Goldilocks black hole; Toxoplasma gondii metabolism; pumping at the speed of muscle
This week: Physicists conducted a biological study, engineers built a waste-recycling suit for astronauts (and worm riders), and astronomers identified the first known intermediate-mass black hole, and it's right here in our own galactic back yard......»»
How astronomers work out the size of the solar system
The size of the solar system is defined by the volume of space over which the sun's influence exceeds those of other nearby stars in the Milky Way galaxy. This influence derives from two fundamental forces of nature: gravity and magnetism......»»
Hubble finds evidence for rare black hole in Omega Centauri
An international team of astronomers has used more than 500 images from the NASA/ESA Hubble Space Telescope spanning two decades to detect seven fast-moving stars in the innermost region of Omega Centauri, the largest and brightest globular cluster i.....»»
Hubble finds mysterious and elusive black hole
For years, astronomers have been searching for elusive intermediate-mass black holes. Now, Hubble has found evidence of one in Omega Centauri......»»
Astronomers discover dozens of double-lined double white dwarf binaries
An international team of astronomers reports the discovery of 34 rare double-lined double white dwarf binary systems using the Intermediate-dispersion Spectrograph and Imaging System (ISIS) on the William Herschel Telescope (WHT). The finding was det.....»»
New NASA Heat Map Shows Scorching Streets That Can Burn Skin in Seconds
Under the scorching summer sun, pavement can reach temperatures hot enough to cause second-degree burns.....»»
Light Is How Astronomers Read the Story of the Universe
Almost everything we know about the cosmos is conveyed by photons traveling across vast distances.....»»
James Webb Space Telescope suggests this exoplanet is our "best bet" at finding an alien ocean

Astronomers find the nearest massive black hole, a missing link in massive black hole formation
Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8,200 solar masses, it is the best candidate for a class of black holes astronomers have long believed.....»»
Astronomers suggest up to 60% of near-Earth objects could be dark comets
Up to 60% of near-Earth objects could be dark comets, mysterious asteroids that orbit the sun in our solar system that likely contain or previously contained ice and could have been one route for delivering water to Earth, according to a University o.....»»
Study investigates the nature of very-high energy gamma-ray source TeV J2032+4130
Using the High-Altitude Water Cherenkov (HAWC) observatory, an international team of astronomers has observed a very-high energy gamma-ray source designated TeV J2032+4130. Results of the observational campaign, presented July 3 on the preprint serve.....»»
Evidence of water vapor detected in the atmosphere of Smertrios
Using the CARMENES spectrograph, astronomers have found evidence of water vapor in the atmosphere of a hot Saturn exoplanet designated HD 149026 b, dubbed Smertrios. The finding, reported in a research paper published on the preprint server arXiv, co.....»»
Beryl downgraded after slamming Texas with deadly rains, wind
Beryl was downgraded Monday evening to a tropical depression after slamming the southern US state of Texas as a Category 1 hurricane, killing at least four people and causing millions to lose power amid scorching summer heat......»»
Astronomers find surprising ice world in the habitable zone with JWST data
A team of astronomers has identified a temperate exoplanet as a promising super-Earth ice or water world......»»
Nearby exoplanet has trace amounts of hydrogen sulfide, Webb data suggest
An exoplanet infamous for its deadly weather has been hiding another bizarre feature—it reeks of rotten eggs, according to a new Johns Hopkins University study of data from the James Webb Space Telescope......»»
