New Saturn-mass exoplanet detected by astronomers
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new Saturn-mass planet orbiting a solar-type star known as TOI-2447. The finding was reported in a research paper published May 12 on the.....»»
High-precision measurements challenge our understanding of Cepheids
"Classical Cepheids" are a type of pulsating star that rhythmically brighten and dim over time. These pulsations help astronomers measure vast distances across space, which makes Cepheids crucial "standard candles" that help us understand the size an.....»»
Coming in hot: NASA"s Chandra checks habitability of exoplanets
Using NASA's Chandra X-ray Observatory and ESA's (European Space Agency's) XMM-Newton, astronomers are exploring whether nearby stars could host habitable exoplanets, based on whether they emit radiation that could destroy potential conditions for li.....»»
Satellite data reveal electromagnetic anomalies up to 19 days before 2023 Turkey earthquake
Earthquakes may betray their impending presence much earlier than previously thought through a variety of anomalies present in the ground, atmosphere and ionosphere that can be detected using satellites, a recent study in the Journal of Applied Geode.....»»
While aiming for massive gas cloud, astronomers spot differences in thickness of Milky Way Galaxy
Space may appear vast and empty, but it's full of cosmological objects that are invisible to the human eye. From our vantage point on Earth, many of these objects fall between astronomers and what they hope to observe, impacting what they find. This.....»»
Astronomers discover parallel disks and jets erupting from a pair of young stars
Most of the universe is invisible to the human eye. The building blocks of stars are only revealed in wavelengths that are outside of the visible spectrum. Astronomers recently used two very different, and very powerful, telescopes to discover twin d.....»»
Observations explore the halo of Centaurus A
Using the Very Large Telescope (VLT) in Chile, astronomers have observed the halo of a nearby giant elliptical galaxy known as Centaurus A. Results of the observational campaign, published June 1 on the pre-print server arXiv, yield important insight.....»»
There are "forever chemicals" in our drinking water: Should standards change to protect our health?
Today's news coverage reports potentially unsafe levels of "forever chemicals" detected in drinking water supplies around Australia. These include human-made chemicals: perfluorooctane sulfonate (known as PFOS) and perflurooctanic acid (PFOA). They a.....»»
Chinese astronomers discover a high-velocity star ejected from globular cluster Messier 15
Chinese astronomers report the discovery of a new high-velocity star about 4,200 light years away. The newfound star, designated J0731+3717, turned out to be ejected from the globular cluster Messier 15 by an intermediate-mass black hole. The finding.....»»
High-precision timing data determine upper limit for photon mass
In a study published in The Astrophysical Journal, Prof. Zhou Xia from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences and collaborators have, for the first time, derived the dispersion relation for photons with nonzer.....»»
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.....»»
Lone star state: Tracking a low-mass star as it speeds across the Milky Way
It may seem like the sun is stationary while the planets in its orbit are moving, but the sun is actually orbiting around the Milky Way galaxy at an impressive rate of about 220 kilometers per second—almost half a million miles per hour. As fast as.....»»
Small, cool and sulfurous exoplanet may help write recipe for planetary formation
A surprising yellow haze of sulfur dioxide in the atmosphere of a gas "dwarf" exoplanet about 96 light years away from our own solar system makes the planet a prime target for scientists trying to understand how worlds are formed......»»
First detection of frost on the solar system"s tallest volcanoes on Mars
For the first time, water frost has been detected on the colossal volcanoes on Mars, which are the largest mountains in the solar system. The international team led by the University of Bern used high-resolution color images from the Bernese Mars cam.....»»
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.....»»
Researcher suggests that gravity can exist without mass, mitigating the need for hypothetical dark matter
Dark matter is a hypothetical form of matter that is implied by gravitational effects that can't be explained by general relativity unless more matter is present in the universe than can be seen. It remains virtually as mysterious as it was nearly a.....»»
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......»»
First case of bird flu detected in Minnesota dairy cows
Bird flu has infected a Benton County dairy herd, marking the first confirmed detection of the virus in cows in Minnesota......»»
