Fluidic telescope (FLUTE): Enabling the next generation of large space observatories
The future of space-based UV/optical/IR astronomy requires ever larger telescopes. The highest priority astrophysics targets, including Earth-like exoplanets, first generation stars, and early galaxies, are all extremely faint, which presents an ongo.....»»
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......»»
Sourdough under the microscope reveals microbes cultivated over generations
Sourdough is the oldest kind of leavened bread in recorded history, and people have been eating it for thousands of years. The components of creating a sourdough starter are very simple—flour and water. Mixing them produces a live culture where yea.....»»
New observatory in Chile—the highest in the world—aims to reveal origins of planets, galaxies and more
How do planets form? How do galaxies evolve? And ultimately, how did the universe itself begin? A unique astronomical observatory that researchers hope will unravel some of the biggest mysteries out there marks its opening on April 30, 2024......»»
Yeast study offers possible answer to why some species are generalists and others specialists
In a landmark study based on one of the most comprehensive genomic datasets ever assembled, a team led by scientists at the University of Wisconsin–Madison and Vanderbilt University offer a possible answer to one of the oldest questions about evolu.....»»
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......»»
Bioluminescence first evolved in animals at least 540 million years ago, pushing back previous oldest dated example
Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study from scientists with the Smithsonian's National Museum of Natural History......»»
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.....»»
New JWST observations reveal black holes rapidly shut off star formation in massive galaxies
New research published in Nature showcases new observations from the James Webb Space Telescope (JWST) that suggest black holes rapidly shut off star-formation in massive galaxies by explosively removing large amounts of gas......»»
New models of Big Bang show that visible universe and invisible dark matter co-evolved
Physicists have long theorized that our universe may not be limited to what we can see. By observing gravitational forces on other galaxies, they've hypothesized the existence of "dark matter," which would be invisible to conventional forms of observ.....»»
James Webb Space Telescope data pinpoint possible aurorae on a cold brown dwarf
Using new observations from the James Webb Space Telescope (JWST), astronomers have discovered methane emission on a brown dwarf, an unexpected finding for such a cold and isolated world. Published in the journal Nature, the findings suggest that thi.....»»
Physicists solve puzzle about ancient galaxy found by Webb telescope
Last September, the James Webb Space Telescope, or JWST, discovered JWST-ER1g, a massive ancient galaxy that formed when the universe was just a quarter of its current age. Surprisingly, an Einstein ring is associated with this galaxy. That's because.....»»
A supernova caused the BOAT gamma ray burst, JWST data confirms
But astronomers puzzled by the lack of signatures of expected heavy elements. Enlarge / Artist's visualization of GRB 221009A showing the narrow relativistic jets—emerging from a central black hole—that gave rise to the brig.....»»
Discovery of pottery rewrites Aboriginal history
The discovery of the oldest pottery ever found in Australia on Jiigurru/Lizard Island off the Queensland coast is challenging the idea that Aboriginal Australian communities were unaware of pottery manufacture before European settlement......»»
The science of static shock jolted into the 21st century
Shuffling across the carpet to zap a friend may be the oldest trick in the book, but on a deep level that prank still mystifies scientists, even after thousands of years of study......»»
New young and warm Jupiter-like exoplanet detected
An international team of astronomers reports the detection of a new young and warm exoplanet orbiting a distant star. The newfound alien world, designated TOI-4862 b (or NGTS-30 b), is similar in size and mass to Jupiter. The finding was published Ap.....»»
Hubble peers at pair of closely interacting galaxies
This image from the NASA/ESA Hubble Space Telescope features Arp 72, a very selective galaxy group that only includes two galaxies interacting due to gravity: NGC 5996 (the large spiral galaxy) and NGC 5994 (its smaller companion, in the lower left o.....»»
Study reports that age is the driving force in changing how stars move within galaxies
Galaxies start life with their stars rotating in an orderly pattern but in some the motion of stars is more random. Until now, scientists have been uncertain about what causes this—possibly the surrounding environment or the mass of the galaxy itse.....»»
Ancient trees help to protect an endangered species
The oldest trees in the forest help to prevent the disappearance of endangered species in the natural environment, according to a study led by the University of Barcelona. This is the case of the wolf lichen—threatened throughout Europe—which now.....»»
Stingray sand "sculpture" in South Africa may be oldest example of humans creating an image of another creature
South Africa's Cape south coast offers many hints about how our human ancestors lived some 35,000 to 400,000 years ago during the Pleistocene epoch. These clues are captured in the dunes they once traversed, today cemented and preserved in a rock typ.....»»
