Astronomers discover two "hot Jupiters" orbiting red-giant stars
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered two new "hot Jupiter" exoplanets. The newfound alien worlds, designated TOI-4377 b and TOI-4551 b, both orbit distant red-giant stars. The.....»»
A galaxy only 350 million years old has surprising amounts of metal
Astrophysicists working with the JWST have found a surprising amount of metal in a galaxy only 350 million years after the Big Bang. How does that fit in with our understanding of the universe?.....»»
A radically new view on dwarf galaxies surrounding the Milky Way
Commonly thought to be long-lived satellites of our galaxy, a new study now finds indications that most dwarf galaxies might, in fact, be destroyed soon after their entry into the Galactic halo......»»
Dwarf galaxies use 10-million-year quiet period to churn out stars
If you look at massive galaxies teeming with stars, you might be forgiven for thinking they are star factories, churning out brilliant balls of gas. But actually, less evolved dwarf galaxies have bigger regions of star factories, with higher rates of.....»»
"Teenage galaxies" are unusually hot, glowing with unexpected elements
Similar to human teenagers, teenage galaxies are awkward, experience growth spurts and enjoy heavy metal—nickel, that is......»»
Physicists answer question of Supergalactic Plane"s absent spiral galaxies
Astrophysicists say they have found an answer to why spiral galaxies like our own Milky Way are largely missing from a part of our local universe called the Supergalactic Plane......»»

The universe is expanding faster than theory predicts—physicists are trying to explain the mismatch
Astronomers have known for decades that the universe is expanding. When they use telescopes to observe faraway galaxies, they see that these galaxies are moving away from Earth......»»
The "Cosmic Vine": Astronomers discover a large structure that hosts at least 20 massive galaxies
An international team of astronomers reports the discovery of a large-scale structure that consists of at least 20 massive galaxies. The structure, dubbed "Cosmic Vine," has a size of about 13 million physical light years. The finding was detailed in.....»»

Daily Telescope: An amazing, colorful view of the Universe
Take a look at two clusters of galaxies that are colliding. Enlarge / This panchromatic view of galaxy cluster MACS0416 was created by combining infrared observations from the NASA/ESA/CSA James Webb Space Telescope with visible-.....»»
Second-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 (JWST)......»»
Oldest black hole discovered dating back to 470 million years after the Big Bang

Scientists find 14 new transient objects in space by peering through the "Christmas Tree Galaxy Cluster"
An international team of scientists, led by University of Missouri's Haojing Yan, used NASA's James Webb Space Telescope (JWST) to discover 14 new transient objects during their time-lapse study of galaxy cluster MACS0416—located about 4.3 billion.....»»
Construction on NASA mission to map 450 million galaxies is under way
NASA's SPHEREx space telescope is beginning to look much like it will when it arrives in Earth orbit and starts mapping the entire sky. Short for Specto-Photometer for the History of the universe, Epoch of Reionization, and Ices Explorer, SPHEREx res.....»»
Astronomers discover how tiny dwarf galaxies form ‘fossils’
When tiny dwarf galaxies age and begin to erode away, they can transform into an even smaller and more dense shape, called an ultra-compact dwarf galaxy......»»
Ancient Egyptian burial reveals ovarian teeth in oldest example of teratoma
A case study led by Southern Illinois University, Illinois, has described the earliest discovery of an ovarian teratoma, a type of tumor that contains well-differentiated tissues developed from three germ cell layers (ectoderm, mesoderm, and endoderm.....»»
