Using the James Webb Space Telescope, astronomers have conducted near- and mid-infrared observations of an extremely metal-poor blue compact dwarf galaxy known as I Zwicky 18. Results of the observational campaign, presented in a paper published Marc.....»»
Astronomers discover a rare eclipsing X-ray binary
An international team of astronomers reports the detection of a rare eclipsing Be/X-ray binary system as part of the Swift Small Magellanic Cloud (SMC) Survey (S-CUBED). The finding was detailed in a research paper published March 12 on the preprint.....»»
Largest-ever map of universe"s active supermassive black holes released
Astronomers have charted the largest-ever volume of the universe with a new map of active supermassive black holes living at the centers of galaxies. Called quasars, the gas-gobbling black holes are, ironically, some of the universe's brightest objec.....»»
The cosmic neutrino background would tell us plenty about the universe, says researcher
Readers of Universe Today are probably already familiar with the concept of the cosmic microwave background (CMB). Its serendipitous discovery by a pair of radio astronomers at Bell Labs is the stuff of astronomical legend. Over the past decades, it.....»»
JWST observations shed more light on the nature of a distant galaxy cluster
Astronomers from the Nanjing University in China and elsewhere have performed high-resolution observations of a distant galaxy cluster known as CL J1001+0220 using the James Webb Space Telescope (JWST). The observational campaign, described in a pape.....»»
Citizen astronomers and AI discover 30,000 ring galaxies
Building on the synergy between citizen astronomer classifications and AI, astronomers have discovered approximately 400,000 spiral galaxies and 30,000 ring galaxies in data from the Subaru Telescope. This is the first example of research building on.....»»
See the stunning Vela supernova remnant in exquisite detail in expansive image
An enormous new image of the ghostly Vela supernova remnant shows off the fascinating and elaborate structure of this striking cosmic object......»»
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.....»»
Webb finds ethanol and other icy ingredients for new worlds
An international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered a variety of molecules, ranging from relatively simple ones like methane to complex compounds like acetic acid and ethanol, in early-stage protosta.....»»
Astronomers perform a comprehensive study of the young open cluster NGC 2345
Using the Himalayan Chandra Telescope (HCT) and ESA's Gaia satellite, Indian astronomers have conducted a comprehensive study of a young open cluster designated NGC 2345. Results of the study, presented March 7 on the preprint server arXiv, shed more.....»»
Dark Energy Camera captures remains of a massive star that exploded nearly 11,000 years ago in huge gigapixel image
This colorful web of wispy gas filaments is the Vela Supernova Remnant, an expanding nebula of cosmic debris left over from a massive star that exploded about 11,000 years ago. Located around 800 light-years away in the constellation Vela (the Sails).....»»
Daily Telescope: Gigantic new stars stir up a nebula
Astronomers know of no other region so packed with large stars as this nebula. Enlarge / Behold, the star-forming region of NGC 604. (credit: NASA, ESA, CSA, STScI) Welcome to the Daily Telescope. There is a little to.....»»
This hot Jupiter is doomed to crash into its star in just three million years
In 2008, astronomers with the SuperWASP survey spotted WASP-12b as it transited in front of its star. At the time, it was part of a new class of exoplanets ("hot Jupiters") discovered a little more than a decade before. However, subsequent observatio.....»»
See planets being born in new images from the Very Large Telescope
Astronomers have peered into the disks of matter from which exoplanets form, looking at more than 80 young stars to see which have planets forming around them......»»
Earth"s earliest forest revealed in Somerset fossils
Scientists have discovered remnants of the Earth's oldest fossil forest on the north coast of Devon and Somerset in the U.K. The trees, which are about 390 million years old, are thought to have grown as part of an extensive forest covering the east.....»»
Observations inspect variability of a nearby ultra-fast rotating active star
Indian astronomers have conducted long-term X-ray observations of a nearby ultra-fast rotating active star known as AB Doradus A. Results of the observational campaign, published February 29 on the pre-print server arXiv, provide crucial insights int.....»»
Subaru Telescope discovers the faintest moon around icy giant planets
Using some of the largest telescopes in the world, including the Subaru Telescope, a team of astronomers discovered three new natural satellites orbiting the outermost planets in our solar system—one around Uranus and two around Neptune. One of the.....»»
