Will we know if TRAPPIST-1e has life?
The search for extrasolar planets is currently undergoing a seismic shift. With the deployment of the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS), scientists discovered thousands of exoplanets, most of which were detec.....»»
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......»»
Observations explore globular cluster system in the galaxy NGC 4262
Using the Canada-France-Hawaii Telescope (CFHT), Indian astronomers have performed wide and deep field observations of a polar ring galaxy known as NGC 4262. Results of the observational campaign, published April 15 on the pre-print server arXiv, she.....»»
Daily Telescope: The ambiguously galactic duo
Hubble continues to deliver the goods. Enlarge / This image from the NASA/ESA Hubble Space Telescope features NGC 3783, a bright barred spiral galaxy about 130 million light-years from Earth. (credit: ESA/Hubble & NASA, M. C. Ben.....»»
Pulsating Snake: First millisecond pulsar discovered in the galactic center
Astronomers from the Australia Telescope National Facility (ATNF) report the discovery of a new millisecond pulsar in the "Snake"—a radio filament in the galactic center. It is the first millisecond pulsar detected in the center of our galaxy. The.....»»
Astronomers offer new model for formation of recently discovered "free-floating" planets
The recent discovery of a potential new class of distant and mysterious "free-floating" planets has intrigued astronomers since stunning new images captured by the James Webb Space Telescope were shared late last year......»»
Astronauts to patch up NASA"s NICER telescope
NASA is planning to repair NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, during a spacewalk later this year. It will be the fourth science observatory in orbit serviced by astronauts......»»
NASA"s Roman space telescope"s "eyes" pass first vision test
Engineers at L3Harris Technologies in Rochester, New York, have combined all 10 mirrors for NASA's Nancy Grace Roman Space Telescope. Preliminary tests show the newly aligned optics, collectively called the IOA (Imaging Optics Assembly), will direct.....»»
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.....»»
Astronomers discover the most metal-poor extreme helium star
Using the Southern African Large Telescope (SALT), astronomers have performed high-resolution observations of a recently detected extreme helium star designated EC 19529–4430. It turned out that EC 19529–4430 is the most metal deficient among the.....»»
Astronomers inspect open cluster Berkeley 50
Using the Lowell Discovery Telescope (LDT), astronomers from the Lowell Observatory in Flagstaff, Arizona, have observed a young Galactic open cluster known as Berkeley 50. Results of the observational campaign, presented April 5 on the preprint serv.....»»
The brightest gamma ray burst ever seen came from a collapsing star
After a journey lasting about two billion years, photons from an extremely energetic gamma-ray burst (GRB) struck the sensors on the Neil Gehrels Swift Observatory and the Fermi Gamma-Ray Space Telescope on October 9th, 2022. The GRB lasted seven min.....»»
Hydrogen recombination found to be most plausible explanation for high levels of energy in stellar superflares
Although their primary purpose is to look for exoplanets, observatories like the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS) have supplied a vast amount of data on stellar flares, detected with high-precision photometr.....»»
Hubble spots a bright galaxy peering out from behind a dark nebula
A new image from the Hubble Space Telescope shows a galaxy partly hidden by a huge cloud of dust known as a dark nebula......»»
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.....»»
Researchers find baby stars discharge plume-like "sneezes" of magnetic flux during formation
Kyushu University researchers have shed new light into a critical question on how baby stars develop. Using the ALMA radio telescope in Chile, the team found that in its infancy, the protostellar disk that surrounds a baby star discharges plumes of d.....»»
If Europa has geysers, they"re very faint
In 2013, the Hubble Space Telescope spotted water vapor on Jupiter's moon Europa. The vapor was evidence of plumes similar to the ones on Saturn's moon Enceladus. That, and other compelling evidence, showed that the moon has an ocean. That led to spe.....»»
Study finds microbes hitchhike on microplastics to reach the sea
The oceans contain large amounts of microplastics, particles that are less than 5 mm in size. In parts of the Baltic Sea, the concentration of microplastics can be as much as 3,300 particles per cubic meter. The microplastics end up in aquatic enviro.....»»
What is a sinkhole? A geotechnical engineer explains
Sinkholes are back in the news after a 13-year-old boy fell down a two meter deep hole in a waterlogged football field in Sydney over the weekend. The boy reportedly sank further into the hole every time he tried to push down with his feet, but was l.....»»
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.....»»
