Studies of geologic faulting on icy moons aid exploration of extraterrestrial...
Earth and space scientists document and reveal the mechanisms behind strike-slip faulting on the largest moon of Saturn, Titan, and Jupiter's largest moon, Ganymede.
View ArticleNew findings support long-proposed process of planet formation
Scientists just made a breakthrough discovery in revealing how planets are made. By observing water vapor in protoplanetary disks, they confirmed a physical process involving the drifting of ice-coated...
View ArticleScientists find 14 new transient objects in space by peering through the...
Scientists have discovered 14 new transient objects during their time-lapse study of galaxy cluster MACS0416 -- located about 4.3 billion light years from Earth -- which they've dubbed as the...
View ArticleGlow in the visible range detected for the first time in the Martian night
Scientists have observed, for the first time in the visible range, a glow on the night side of the planet Mars. These new observations provide a better understanding of the dynamics of the upper...
View ArticleMilky Way-like galaxy found in the early universe
Astronomers have discovered the most distant barred spiral galaxy, similar to the Milky Way, that has been observed to date.
View ArticleSecond-most distant galaxy discovered using James Webb Space Telescope
The second- and fourth-most distant galaxies ever observed have been discovered in a region of space known as Pandora's Cluster, or Abell 2744, using data from NASA's James Webb Space Telescope.
View ArticleScientists uncover aurora-like radio emission above a sunspot
Astronomers have detailed radio observations of an extraordinary aurora-like display -- occurring 40,000 km above a relatively dark and cold patch on the Sun, known as a sunspot.
View ArticleGalactic 'lightsabers': Answering longstanding questions about jets from...
The one thing everyone knows about black holes is that absolutely everything nearby gets sucked into them. Almost everything, it turns out. Astrophysicists have now determined conclusively that energy...
View ArticleUsing eclipses to calculate the transparency of Saturn's rings
A student has measured the optical depth of Saturn's rings using a new method based on how much sunlight reached the Cassini spacecraft while it was in the shadow of the rings.
View Article'Bouncing' comets could deliver building blocks for life to exoplanets
How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers have shown how comets could deposit similar...
View ArticleDownloading NASA's dark matter data from above the clouds
Data from a NASA mission to map dark matter around galaxy clusters has been saved by a new recovery system. The system allowed the retrieval of gigabytes of information, even after communication failed...
View ArticleJames Webb Space Telescope detects water vapor, sulfur dioxide and sand...
Astronomers have used recent observations made with the James Webb Space Telescope to study the atmosphere of the nearby exoplanet WASP-107b. Peering deep into the fluffy atmosphere of WASP-107b they...
View ArticleWith unprecedented flares, stellar corpse shows signs of life
After a distant star's explosive death, an active stellar corpse was the likely source of repeated energetic flares observed over several months -- a phenomenon astronomers had never seen before,...
View ArticleAn old star with ring-like structure: ALMA demonstrates highest resolution yet
ALMA (Atacama Large Millimeter/submillimeter Array) has demonstrated the highest resolution yet with observations of an old star. The observations show that the star is surrounded by a ring-like...
View Article'Teenage galaxies' are unusually hot, glowing with unexpected elements
Using the James Webb Space Telescope, CECILIA Survey receives first data from galaxies forming two-to-three billion years after the Big Bang. By examining light from these 33 galaxies, researchers...
View ArticleWhy the vast supergalactic plane is teeming with only one type of galaxy
Our own Milky Way galaxy is part of a much larger formation, the local Supercluster structure, which contains several massive galaxy clusters and thousands of individual galaxies. Due to its...
View ArticleDwarf galaxies use 10-million-year quiet period to churn out stars
If you look at massive galaxies teeming with stars, you might be forgiven in thinking they are star factories, churning out brilliant balls of gas. But actually, less evolved dwarf galaxies have bigger...
View Article'Triple star' discovery could revolutionize understanding of stellar evolution
A ground-breaking new discovery could transform the way astronomers understand some of the biggest and most common stars in the Universe. Research by PhD student Jonathan Dodd and Professor René...
View ArticleNASA's Webb reveals new features in heart of Milky Way
The latest image from NASA's James Webb Space Telescope shows a portion of the dense center of our galaxy in unprecedented detail, including never-before-seen features astronomers have yet to explain....
View ArticleTelescope Array detects second highest-energy cosmic ray ever
In 1991, an experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray’s energy shocked astrophysicists. Nothing in our galaxy had the power to...
