Astronomers think they’ve figured out how and when Jupiter’s Red Spot formed
Astronomers concluded it is not the same and that Cassini's spot disappeared in 1708. Enlarge / Enhanced Juno image of Jupiter’s Great Red Spot in 2018. It is likely not the same one observed by Cassini in the 1600s. (credit: G.....»»
Webb Space Telescope captures star clusters in Cosmic Gems arc
An international team of astronomers has used the NASA/ESA/CSA James Webb Space Telescope to discover gravitationally bound star clusters when the universe was 460 million years old. This is the first discovery of star clusters in an infant galaxy le.....»»
Mystery of massive aurora in Arctic skies in December 2022 solved by astronomers
A small team of astronomers affiliated with several institutions in Japan, working with a pair of colleagues in the U.S., has solved the mystery of the unusually smooth aurora that appeared in the Arctic sky in December of 2022......»»
Astronomers find three potential super-Earths around nearby star
Astronomers have discovered three potential "super-Earth" exoplanets orbiting a relatively nearby orange dwarf star. This groundbreaking find was made by an international team of researchers led by Dr. Shweta Dalal from the University of Exeter......»»
Defunct satellites burning up in the atmosphere could damage the ozone layer
Communications companies such as Starlink plan to launch tens of thousands of satellites into orbit around Earth over the next decade or so. The growing swarm is already causing problems for astronomers, but recent research has raised another questio.....»»
Striking new Webb image showing alignment of bipolar jets confirms star formation theories
For the first time, a phenomenon astronomers have long hoped to image directly has been captured by the NASA/ESA/CSA James Webb Space Telescope's Near-InfraRed Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the n.....»»
Supermassive black hole appears to grow like a baby star
Supermassive black holes pose unanswered questions for astronomers around the world, not the least of which is "How do they grow so big?" Now, an international team of astronomers, including researchers from Chalmers University of Technology in Swede.....»»
Galaxy NGC 4696 hosts a complex globular cluster system, observations find
Using the Magellan Telescopes in Chile, astronomers have performed photometric observations of a giant elliptical galaxy known as NGC 4696. The observations reveal that the galaxy has a complex globular cluster system. The finding was detailed in a p.....»»
Observations explore stellar content of nearby young open cluster Berkeley 59
Astronomers from India and Thailand have observed a young nearby open cluster known as Berkeley 59. Results of the observational campaign, published June 12 on the pre-print server arXiv, deliver essential information regarding low-mass stellar and s.....»»
Supermassive black hole roars to life as astronomers watch in real time
A similar awakening may one day occur with the Milky Way's supermassive black hole Artist’s animation of the black hole at the center of SDSS1335+0728 awakening in real time—a first for astronomers. In December 2019, astronomers.....»»
Astronomers discover an Earth-sized exoplanet orbiting a nearby ultracool dwarf star
An international team of astronomers reports the discovery of a new Earth-sized exoplanet that orbits an ultracool dwarf star located just 54.6 light years away. The newfound alien world, designated SPECULOOS-3 b, is slightly smaller but much hotter.....»»
High-precision measurements challenge our understanding of Cepheids
"Classical Cepheids" are a type of pulsating star that rhythmically brighten and dim over time. These pulsations help astronomers measure vast distances across space, which makes Cepheids crucial "standard candles" that help us understand the size an.....»»
Coming in hot: NASA"s Chandra checks habitability of exoplanets
Using NASA's Chandra X-ray Observatory and ESA's (European Space Agency's) XMM-Newton, astronomers are exploring whether nearby stars could host habitable exoplanets, based on whether they emit radiation that could destroy potential conditions for li.....»»
Atmospheric sulfur dioxide levels hit historic high in Scotland following Icelandic volcanic eruption
Edinburgh, no stranger to an occasional haze, experienced an unprecedented atmospheric event on 31 May, unlike any seen over the past 30 years. While sea haar from the North Sea often blankets Scotland's capital, the haze observed that Friday felt di.....»»
While aiming for massive gas cloud, astronomers spot differences in thickness of Milky Way Galaxy
Space may appear vast and empty, but it's full of cosmological objects that are invisible to the human eye. From our vantage point on Earth, many of these objects fall between astronomers and what they hope to observe, impacting what they find. This.....»»
Astronomers discover parallel disks and jets erupting from a pair of young stars
Most of the universe is invisible to the human eye. The building blocks of stars are only revealed in wavelengths that are outside of the visible spectrum. Astronomers recently used two very different, and very powerful, telescopes to discover twin d.....»»
Observations explore the halo of Centaurus A
