An international team of researchers led by astronomers from Leiden University (Netherlands) has produced the first sharp radio maps of the universe at low frequencies. Thanks to a new calibration technique, they bypassed the disturbances of the Eart.....»»
Ariane 6 launches: Exolaunch"s EXOpod Nova
Europe's newest rocket soon launches, taking with it many space missions each with a unique objective, destination and team at home, cheering them on. Whether launching new satellites to look back and study Earth, peer out to deep space or test impor.....»»
Astronomers inspect population of young stellar objects in open cluster NGC 346
Using the James Webb Space Telescope (JWST), an international team of astronomers has explored young stellar objects (YSOs) in an open cluster known as NGC 346. The study, published April 24 on the preprint server arXiv, yields crucial information ab.....»»
James Webb observes extremely hot exoplanet with 5,000 mph winds
Astronomers using the James Webb telescope have modeled the weather on a distant exoplanet, revealing winds whipping around at speeds of 5,000 miles per hour......»»
X-ray satellite XMM-Newton sees "space clover" in a new light
Astronomers have discovered enormous circular radio features of unknown origin around some galaxies. Now, new observations of one dubbed the Cloverleaf suggest it was created by clashing groups of galaxies......»»
TOI-837 b is a young Saturn-sized exoplanet with a massive core, observations find
European astronomers have performed photometric and spectroscopic observations of a distant giant exoplanet known as TOI-837 b. As a result, they found that TOI-837 b is a young Saturn-sized planet containing a massive core, which challenges current.....»»
Researchers explore an old galactic open cluster
Using data from ESA's Gaia satellite, astronomers from Turkey and India have investigated NGC 188—an old open cluster in the Milky Way. Results of the study, published April 19 on the pre-print server arXiv, deliver important insights into the para.....»»
Astronomers" simulations support dark matter theory
Computer simulations by astronomers support the idea that dark matter—matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe—exists, according to the resear.....»»
Neutron stars could be capturing primordial black holes
The Milky Way has a missing pulsar problem in its core. Astronomers have tried to explain this for years. One of the more interesting ideas comes from a team of astronomers in Europe and invokes dark matter, neutron stars, and primordial black holes.....»»
Q&A: How to catch a glimpse of a new star about to appear in the night sky
If you peer up at the constellation Corona Borealis—the Northern Crown—over the next several months, you may catch a glimpse: Astronomers predict that sometime this year, a new star will appear in the night sky, growing as bright as the North Sta.....»»
Tidal disruption event ASASSN-19bt experiences unusual radio evolution, observations show
An international team of astronomers has conducted detailed radio and X-ray observations of a tidal disruption event (TDE) designated ASASSN-19bt. Results of the observational campaign, presented April 18 on the pre-print server arXiv, shed more ligh.....»»
Orion"s erupting star system reveals its secrets
An unusual group of stars in the Orion constellation have revealed their secrets. FU Orionis, a double star system, first caught astronomers' attention in 1936 when the central star suddenly became 1,000 times brighter than usual. This behavior, expe.....»»
Mapping the Milky Way"s magnetic field in 3D
We are all very familiar with the concept of the Earth's magnetic field. It turns out that most objects in space have magnetic fields but it's quite tricky to measure them. Astronomers have developed an ingenious way to measure the magnetic field of.....»»
Research investigates radio emission of the rotating radio transient RRAT J1854+0306
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have investigated radio emission from a rotating radio transient known as RRAT J1854+0306. Results of the study, published April 15 on the preprint server arX.....»»
TESS finds its first rogue planet
Well over 5,000 planets have been found orbiting other star systems. One of the satellites hunting for them is TESS, the Transiting Exoplanet Survey Satellite. Astronomers using TESS think they are made a rather surprising discovery; their first free.....»»
Recently discovered black hole is part of a nearby disrupted star cluster, study finds
European astronomers have investigated a recently detected black hole designated Gaia BH3. In their results, they found that the black hole is associated with a nearby disrupted star cluster known as ED-2. The finding is reported in a paper published.....»»
Black hole "traffic jams" discovered in galactic centers by astronomers
An international study, led by researchers from Monash University, has revealed crucial insights into black hole dynamics within massive disks at the centers of galaxies......»»
International team detects eruption of mega-magnetic star in nearby galaxy
While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays—high-energy photons—coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explos.....»»
Star bars show universe"s early galaxies evolved much faster than previously thought
The universe's early galaxies were less chaotic and developed much faster than previously thought, according to new research looking back more than ten billion years in time. An international team of astronomers led by Durham University, UK, has used.....»»
