Stargazing in broad daylight: How a multi-lens telescope is changing astronomy
Astronomers at Macquarie University have pioneered a new technique for observing celestial objects during the day, potentially allowing around-the-clock visual monitoring of satellites and greatly improving safety on Earth and in space......»»
Astronomers observe jet reorientation in "Death Star" black holes
Huge black holes are firing powerful beams of particles into space—and then changing their aim to fire at new targets. This discovery, made using NASA's Chandra X-ray Observatory and the U.S. National Science Foundation (NSF) National Radio Astrono.....»»
Using wobbling stellar material, astronomers measure the spin of a supermassive black hole for the first time
Astronomers at MIT, NASA, and elsewhere have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting......»»
Nova explosion visible to the naked eye expected any day now
Sometime between May and September, a white dwarf is expected to go thermonuclear. Enlarge / Aftermath of a nova at the star GK Persei. (credit: NASA/CXC/RIKEN/STScI/NRAO/VLA) When you look at the northern sky, you can f.....»»
Observations investigate properties of nearby brown dwarf HD 33632 Ab
Using the Keck II telescope in Hawaii, astronomers have observed a nearby brown dwarf known as HD 33632 Ab. Results of the observational campaign, presented in a paper published May 14 on the pre-print server arXiv, provide more insights into the pro.....»»
Astronomers determine Mars may face more potentially hazardous asteroids than Earth
A team of astronomers at Nanjing University has found evidence that Mars likely has more potentially hazardous asteroids in its path than Earth. In their study, posted on the arXiv preprint server, the group investigated the number of potentially haz.....»»
REBELS-25 is a dynamically cold disk galaxy, observations find
An international team of astronomers has observed a high-redshift massive star-forming galaxy known as REBELS-25. They found that REBELS-25 is a dynamically cold disk galaxy. This finding was presented in a research paper published May 9 on the pre-p.....»»
Seafloor life devastated near explosive volcanic eruption in Pacific, research shows
A University of Rhode Island oceanographer leading her first research cruise in the southern Pacific uncovered a surprise when her vessel looked below the waters in the Polynesian nation of Tonga......»»
Three new RR Lyrae variable stars discovered
Using the Lulin One-meter Telescope (LOT), astronomers have observed a newly detected candidate ultra-faint dwarf galaxy known as Virgo III. As a result, they discovered three new RR Lyrae variable stars in the vicinity of this galaxy. The finding wa.....»»
Webb detects most distant black hole merger to date
An international team of astronomers have used the NASA/ESA/CSA James Webb Space Telescope to find evidence for an ongoing merger of two galaxies and their massive black holes when the universe was only 740 million years old. This marks the most dist.....»»
Astronomers discover new Earth-sized world orbiting an ultra-cool star
An international team of astronomers has detected a new, Earth-sized planet just 55 light years away, orbiting an ultra-cool red dwarf star......»»
Astronomers discover merging twin quasars
Using the Subaru Telescope in Hawaii, astronomers have detected a pair of merging quasars at a high redshift, as part of the Hyper SuprimeCam (HSC) Subaru Strategic Program (SPP) survey. The serendipitous discovery is reported in the latest issue of.....»»
Raspberry in the sky: Astronomers discover a new supernova remnant candidate
Astronomers from the Western Sydney University in Australia and elsewhere report the detection of a new supernova remnant (SNR) candidate. The newfound SNR candidate, dubbed "Raspberry" due to its morphology, was identified in the near side of the Mi.....»»
Clues from deep magma reservoirs could improve volcanic eruption forecasts
New research into molten rock 20km below the Earth's surface could help save lives by improving the prediction of volcanic activity......»»
Astronomers are on the hunt for Dyson spheres
There's something poetic about humanity's attempt to detect other civilizations somewhere in the Milky Way's expanse. There's also something futile about it. But we're not going to stop. There's little doubt about that......»»
Astronomers propose a new stellar theory to explain the origin of phosphorus
Astronomers have proposed a new theory to explain the origin of phosphorus, one of the elements important for life on Earth. The theory suggests a type of stellar explosion known as "ONe novae" as a major source of phosphorus......»»
Research investigates the environment of globular cluster NGC 6355
Using the Dark Energy Camera (DECam), Argentinian astronomers have investigated the environment of a galactic globular cluster known as NGC 6355. The study, presented in a paper published May 2 on the pre-print server arXiv, found that the cluster ha.....»»
Astronomers explore globular cluster NGC 2419
Using the Indian Astronomical Observatory (IAO) and ESA's Gaia satellite, astronomers have explored a galactic globular cluster known as NGC 2419. Results of the study, published April 29 on the preprint server arXiv, shed more light on the propertie.....»»
How NASA"s Roman mission will hunt for primordial black holes
Astronomers have discovered black holes ranging from a few times the sun's mass to tens of billions. Now a group of scientists has predicted that NASA's Nancy Grace Roman Space Telescope could find a class of "featherweight" black holes that has so f.....»»
Astronomers observe elusive stellar light surrounding ancient quasars
MIT astronomers have observed the elusive starlight surrounding some of the earliest quasars in the universe. The distant signals, which trace back more than 13 billion years to the universe's infancy, are revealing clues to how the very first black.....»»
