Astronomers think they’ve found a plausible explanation of the Wow! signal
Magnetars could zap clouds of atomic hydrogen, producing focused microwave beams. Enlarge / The Wow! signal, represented as "6EQUJ5," was discovered in 1977 by astronomer Jerry Ehman. (credit: Public domain) An unusually.....»»
Astronomers detect black hole "starving" its host galaxy to death
Astronomers have used the NASA/ESA James Webb Space Telescope to confirm that supermassive black holes can starve their host galaxies of the fuel they need to form new stars. The results are reported in the journal Nature Astronomy......»»
The skyscraper-sized tsunami that vibrated through the entire planet and no one saw
Earthquake scientists detected an unusual signal on monitoring stations used to detect seismic activity during September 2023. We saw it on sensors everywhere, from the Arctic to Antarctica......»»

Astronomers discover new planet in Great Bear constellation
Astronomers from the Nicolaus Copernicus University in Torun have discovered a new planet in the constellation of the Great Bear. It has a mass as much as 11 times that of Jupiter, orbits its star in 14 years and has a temperature of no more than min.....»»
Huge gamma-ray burst collection "rivals 250-year-old Messier catalog," say astronomers
Hundreds of gamma-ray bursts (GRBs) have been recorded as part of an enormous global effort so extensive it "rivals the catalog of deep-sky objects created by Messier 250 years ago", astronomers say......»»
Webb peers into the Extreme Outer Galaxy
Astronomers have directed NASA's James Webb Space Telescope to examine the outskirts of our Milky Way galaxy. Scientists call this region the Extreme Outer Galaxy due to its location more than 58,000 light-years away from the Galactic Center. (For co.....»»
Climate change-triggered landslide unleashes a 650-foot mega-tsunami
In September 2023, scientists around the world detected a mysterious seismic signal that lasted for nine straight days. An international team of scientists, including seismologists Alice Gabriel and Carl Ebeling of UC San Diego's Scripps Institution.....»»
Astronomers discover a long-hidden small black hole in an unusually evolved binary system
Chinese researchers have discovered a promising mass-gap black hole using radial velocity and astrometry methods. The study was published online in Nature Astronomy on Sept. 10, and was conducted by a team led by Dr. Wang Song, an associate researche.....»»
Astronomers track bubbles on star"s surface
For the first time, astronomers have captured images of a star other than the sun in enough detail to track the motion of bubbling gas on its surface. The images of the star, R Doradus, were obtained with the Atacama Large Millimeter/submillimeter Ar.....»»
New dense sub-Saturn exoplanet discovered
Using the Transiting Exoplanet Survey Satellite (TESS), astronomers from the Physical Research Laboratory (PRL) in Ahmedabad, India and elsewhere, have detected a new sub-Saturn exoplanet with a relatively high density. The finding was reported in a.....»»
Formation of super-Earths proven limited near metal-poor stars
In a new study, astronomers report novel evidence regarding the limits of planet formation, finding that after a certain point, planets larger than Earth have difficulty forming near low-metallicity stars......»»
Hidden, compact galaxies in the distant universe—searching for the secrets behind the little red dots
Astronomers exploring the faraway universe with the James Webb Space Telescope, NASA's most powerful telescope, have found a class of galaxies that challenges even the most skillful creatures in mimicry—like the mimic octopus. This creature can imp.....»»
WaveCore runs right through a concrete wall with gigabit-speed network signal
Core drilling is tricky. Getting a 6 GHz signal through concrete is now easier. Enlarge / "Hmm, no signal here. I'm trying to figure it out, but nothing comes to mind …" (credit: Getty Images) One issue in getting offi.....»»
Study shows how amateur astronomers can aid in Jupiter weather monitoring
Jupiter's striking appearance comes from its stormy atmosphere. Swirling clouds surround the gas giant, and their distribution reflects the planet's weather. Scientists have used professional observatories such as the Very Large Telescope in Chile (w.....»»
Astronomers discover iron winds on an ultra-hot exoplanet
An international team of astronomers, including scientists from the University of Geneva (UNIGE) and the PlanetS National Center of Competence in Research, has identified the presence of iron winds in the atmosphere of the ultra-hot Jupiter WASP-76 b.....»»
Q&A: Astronomers await a once-in-80-year stellar explosion
We sat down with Carnegie Science Observatories theoretical astrophysicist Tony Prio to talk about T Coronae Borealis, the stellar explosion that occurs once every 80 years and is due to light up in the coming months......»»
New Horizons spacecraft measurements shed light on the darkness of the universe
Just how dark is deep space? Astronomers may have finally answered this long-standing question by tapping into the capabilities and distant position of NASA's New Horizons spacecraft, by making the most precise, direct measurements ever of the total.....»»
Is Betelgeuse actually a binary star?
Betelgeuse has been a favorite among amateur astronomers for many years. However you pronounce it, its unexpected dimming draws even more attention to this red supergiant variable star in Orion. It has a few cycles of variability. One of them occurs.....»»
