Astronomers propose a 50-meter submillimeter telescope
Some parts of the universe only reveal important details when observed in radio waves. That explains why we have ALMA, the Atacama Large Millimeter–submillimeter Array, a collection of 7-meter and 12-meter radio telescopes that work together as an.....»»
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.....»»
Hubble spots magnificent barred galaxy NGC 2217
The magnificent central bar of NGC 2217 (also known as AM 0619-271) shines bright in the constellation of Canis Major (The Greater Dog), in this image taken by the NASA/ESA Hubble Space Telescope. Roughly 65 million light-years from Earth, this barre.....»»
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.....»»
Topologically controlled multiskyrmions: Researchers propose a new family of quasiparticles
Skyrmions are topologically protected quasiparticles with sophisticated spin textures, widely studied in condensed-matter systems, magnets and recently in photonics, which predicts great potential in ultra-high-capacity information storage, due to th.....»»
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.....»»
Webb captures iconic Horsehead Nebula in unprecedented detail
The NASA/ESA/CSA James Webb Space Telescope has captured the sharpest infrared images to date of one of the most distinctive objects in our skies, the Horsehead Nebula. These observations show a part of the iconic nebula in a whole new light, capturi.....»»
James Webb captures the edge of the beautiful Horsehead Nebula
A new image from the James Webb Space Telescope shows the sharpest infrared view to date of a portion of the famous Horsehead Nebula......»»
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.....»»
Gigantic Jurassic raptor footprints unearthed in China
Scientists have discovered the tracks of a 5 meter-long raptor dinosaur, challenging what was previously known about the species' size range......»»

Can an online library of classic video games ever be legal?
Preservationists propose access limits, but industry worries about a free "online arcade." Enlarge / The Q*Bert's so bright, I gotta wear shades. (credit: Aurich Lawson | Getty Images | Gottlieb) For years now, video gam.....»»
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.....»»
