Paleontologists have found a fossilized jaw fragment and three isolated teeth from a new, relatively large (by Late Cretaceous standards) metatherian species in the layers of the Williams Fork ...

At a distance of about 1,400 parsecs (4,600 light-years), Cygnus OB2 is the closest massive young association to the Sun. It contains hundreds of massive stars as well as thousands of lower-mass stars ...

Dedicated to the Egyptian deity Khnum, the temple of Esna is one of the last examples of ancient Egyptian temple architecture. Only the vestibule, called the pronaos, of the original temple complex ...

The well-studied V404 Cygni, an X-ray binary hosting a low-mass black hole, is part of a wide hierarchical triple with a tertiary companion at least 3,500 astronomical units (AU) away from the inner ...

Gliese 229B was the first known brown dwarf, discovered in 1995. In new research, astronomers observed Gliese 229 B with the GRAVITY interferometer and, separately, the CRIRES+ spectrograph at ESO’s ...

Marine biologists have found adult tubeworms and other vent animals below the seafloor in the East Pacific Rise, a volcanically active, fast-spreading ridge with numerous hydrothermal vent fields. The ...

Paleontologists say they’ve identified a new species of marine reptile in the ophthalmosaurid genus Platypterygius that lived approximately 125 million years ago. Ophthalmosauridae are a family of ...

Astronomers using the NASA/ESA Hubble Space Telescope have made a unique timelapse of R Aquarii’s dynamic behavior from observations spanning from 2014 to 2023. Located 650 light-years away, R Aquarii ...

Geckos use the saccule — a part of their inner ear traditionally associated with maintaining balance and body positioning — to detect low-frequency vibrations, according to a duo of biologists at the ...

The venom of black widow spiders contains a cocktail of seven specific latrotoxins, but only one — α-latrotoxin — targets vertebrates, including humans. Chemists at the University of Münster have now ...

Paleontologists have identified a new genus and species of sauropod dinosaur from a semi-articulated specimen found in the 1990s in northern Wyoming, the United States. The newly-described species ...
