Anyone can become an asteroid hunter thanks to a new program launched by astronomers at the University of Arizona Lunar and Planetary Laboratory. As part of the Catalina Sky Survey, the scientists created an online portal that opens their mission—t.....»»
Gamma-rays with energies of up to 13 teraelectronvolts measured for brightest burst of all time
Astronomers with The LHAASO Collaboration have found that last year's GRB 221009A gamma-ray burst, subsequently nicknamed the Brightest of All Time (BOAT), carried with it 13 teraelectronvolts of energy. In their study, reported in the journal Scienc.....»»
3 Reasons Why You Shouldn’t Buy the iPhone 8 in 2023
If you’re hunting for a new smartphone in 2023, you’ll probably want to avoid the iPhone 8 and iPhone 8 Plus. The iPhone 8 and iPhone 8 Plus, both of which launched back in 2017, might be tempting if you’re on a budget, but these mo.....»»
The universe is expanding faster than theory predicts—physicists are trying to explain the mismatch
Astronomers have known for decades that the universe is expanding. When they use telescopes to observe faraway galaxies, they see that these galaxies are moving away from Earth......»»
The "Cosmic Vine": Astronomers discover a large structure that hosts at least 20 massive galaxies
An international team of astronomers reports the discovery of a large-scale structure that consists of at least 20 massive galaxies. The structure, dubbed "Cosmic Vine," has a size of about 13 million physical light years. The finding was detailed in.....»»
Testing of citizen scientist discovery suggests it is on the boundary between comet and asteroid
A team of space scientists, astronomers and astrophysicists affiliated with multiple institutions across the U.S., working with a colleague from Italy, has determined that a celestial object spotted by citizen scientists back in 2016 is neither a com.....»»
Study describes 48 new species of spiders
A paper recently published in Zootaxa documents the 48 species of ground-hunting spiders from the family Miturgidae, which can be found across Australia, particularly in arid habitats in open eucalypt forest, brigalow, mallee, heath, and desert......»»
ALMA observations shed more light on molecular clouds associated with supernova remnant LHA 120-N49
Using the Atacama Large Millimeter/Submillimeter Array (ALMA), an international team of astronomers has observed a supernova remnant known as LHA 120-N49. Results of the observational campaign, published November 3 on the pre-print server arXiv, prov.....»»
Scientists uncover aurora-like radio emission above a sunspot
In a study published in Nature Astronomy, astronomers from New Jersey Institute of Technology's Center for Solar-Terrestrial Research (NJIT-CSTR) have detailed radio observations of an extraordinary aurora-like display occurring 40,000 km above a rel.....»»
Astronomers find dozens of massive stars fleeing the Milky Way
The Milky Way can't hold onto all of its stars. Some of them get ejected into intergalactic space and spend their lives on an uncertain journey. A team of astronomers took a closer look at the most massive of these runaway stars to see what they coul.....»»
Some of the moon"s craters are from interstellar impacts. Can we tell which?
By discovering two interstellar objects (ISOs), we know that asteroids and comets from other star systems pass through the solar system from time to time. By inference, some of these must have crashed into the moon, creating impact craters. If we cou.....»»
Astronomers discover how tiny dwarf galaxies form ‘fossils’
When tiny dwarf galaxies age and begin to erode away, they can transform into an even smaller and more dense shape, called an ultra-compact dwarf galaxy......»»
How we"re building the world"s biggest optical telescope to crack some of the greatest puzzles in science
Astronomers get to ask some of the most fundamental questions there are, ranging from whether we're alone in the cosmos to what the nature of the mysterious dark energy and dark matter making up most of the universe is......»»
Astronomers are hoping to detect gravitational waves coming from supernova 1987A
A supernova explosion is a cataclysmic explosion that marks the violent end of a massive star's life. During the event, the star releases immense amounts of energy, often outshining the combined light from all the stars in the host galaxy for a very.....»»
Dwarf galaxies stripped of stars prove to be the missing link in the formation of rare ultra-compact dwarf galaxies
Astronomers using the Gemini North telescope, one-half of the International Gemini Observatory operated by NSF's NOIRLab, have captured the eroding remains of more than 100 dwarf galaxies as they transition into ultra-compact dwarf galaxies, objects.....»»
Five new pulsars discovered with FAST
Using the Five-hundred Aperture Spherical Telescope (FAST), astronomers from China and Australia have discovered five new pulsars, two of which turned out to have ultra-short spin periods. The finding was reported in a research paper published Novemb.....»»
Daily Telescope: Lucy continues to surprise astronomers with its first flyby
"We never suspected anything so bizarre!" Enlarge / This image shows the asteroid Dinkinesh and its satellite as seen by the Lucy Long-Range Reconnaissance Imager (L’LORRI) as NASA’s Lucy Spacecraft departed the system. (cre.....»»
See the stunning first images taken by the dark matter-hunting Euclid telescope
The European Space Agency has released the first five full-color images taken by Euclid, a space telescope launched earlier this year to probe dark matter......»»
New Webb images show gas-rich baby galaxies setting the early universe alight
New images from the James Webb Space Telescope (JWST) have helped Australian astronomers unlock secrets of how infant galaxies started an explosion of star formation in the very early universe......»»
TESS discovers Saturn-like planet orbiting an M-dwarf star
Astronomers have discovered a new giant exoplanet orbiting an M-dwarf star using NASA's Transiting Exoplanet Survey Satellite (TESS). The newly detected alien world, designated TOI-5344 b is similar in size and mass to Saturn. The finding is reported.....»»
Old data from Kepler turns up a system with seven planets
