WASP-121b May Have Formed Much Closer to Its Parent Star than Previously Believed Possible
Astronomers using the Immersion GRating INfrared Spectrograph (IGRINS) instrument on the Gemini South telescope have examined the atmosphere of WASP-121b, one of the most extensively studied ultrahot Jupiters. This artist’s illustration shows WASP-121b, an alien world that is losing magnesium and iron gas from its atmosphere. Image credit: NASA / ESA / J. Olmsted, STScI.
Paleontologists Find Original Collagen in Fossil Bone of Edmontosaurus
Detection of soft tissues (e.g., proteins) in fossil bones is a growing field of study and a new study led by University of Liverpool paleontologists contributes to the list of such findings. Using a combination of three independent analytical techniques, the authors show that collagenous protein remnants in some dinosaur bones are original to the
Hubble Captures Type Ia Supernova and Its Host Galaxy
A type Ia supernova event called SN 2022abvt was discovered two years ago in the spiral galaxy LEDA 132905.

Long-Handed Ostrich-Like Dinosaur Unearthed in Mexico
A bizarre new genus and species of ornithomimid dinosaur has been identified from the fossilized remains found in 2014 in Coahuila, Mexico. Life reconstruction of Mexidracon longimanus. Image credit: Ddinodan / CC BY 4.0. The newly-identified dinosaur species roamed Earth during the Late Cretaceous epoch, some 73 million years ago. Named Mexidracon longimanus, the ancient
Auricular Muscles Scientists Thought We Didn’t Use Actually Activate When We Listen Hard
If you can wiggle your ears, you can use the auricular muscles, which helped our distant ancestors listen closely. These muscles helped change the shape of the pinna, or the shell of the ear, funneling sound to the eardrums. Millions of years ago, our ancestors stopped using them, so humans’ auricular muscles are only vestigial.
