By Ashley Strickland, CNN (CNN) — Astronomers have detected an astonishing celestial object emitting bright flashes of radio waves and X-rays that last for two minutes and repeat every 44 minutes. In a fresh twist, the discovery marks the first time powerful X-rays have been associated with an object that might be a long-period transient.

The prehistoric predator that went extinct about 3.6 million years ago was not hunting only large marine mammals such as whales as researchers widely thought, a new study has found. Instead,

Ginger kitties are known among cat owners for being particularly friendly and feisty. To geneticists, however, the uniqueness of these house cats comes from the unusual

They have bellies so full of fragments, they crunch when touched. Lord Howe Island — a speck of land about 370 miles off mainland Australia, home to just a few

The tracks also push back the origin of amniotes, a group that includes reptiles, birds and mammals, and provide new

The Federal Aviation Administration, which licenses commercial rocket launches, said Thursday

While our teeth are covered in hard enamel, it’s dentine — the tooth’s inner layer responsible for carrying sensory information to

By Mindy Weisberger, CNN (CNN) — When a fossil preserves an animal’s complete body in a death pose, seeing it is observing a snapshot in time. Several such fossils exist for Archaeopteryx — the earliest known bird — and now, a remarkable specimen that was off-limits to scientists for decades is offering previously unseen evidence
