It’s 7 billion years ago, and the Universe’s heyday of star formation is beginning to slow. What might our Milky Way Galaxy have looked like at that time? Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found clues in the form of a cosmic question mark, the result of a rare alignment across light-years
In a paper published in the journal Nature Geoscience, scientists offer a new explanation for a string of severe environmental crises, called oceanic anoxic events, which happened between 185 and 85 million years ago (Mesozoic era); these occurred when the seas became critically depleted of dissolved oxygen. Oceanic anoxic events are geologically abrupt phases of
Paleontologists have unearthed the skeletal remains from a previously unknown species of lithostrotian titanosaur at the fossil site of Lo Hueco, Cuenca, Spain.

Around a fifth of U.K. citizens believe Earth has been visited by extraterrestrials, and an estimated 7% believe that they have seen a UFO. The figures are even higher in the U.S. — and rising. The number of people who believe UFO sightings offer likely proof of alien life increased from 20% in 1996 to

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 Very Large Telescope. Both sets of observations independently resolved Gliese 229B into two components, Gliese 229 Ba and Bb. They orbit each other every 12.1 days with a semimajor axis of
