The colorful fireball mesmerized onlookers—and its unexpected appearance surprised astronomers who are hoping to better predict when space rocks enter Earth's atmosphere

An artist's concept of 55 Cancri e and its sun. The star is much closer to its sun than any planet in our solar system, so it is too hot to support life.

Astronomers Discover an Atmosphere on a Hot, Rocky Exoplanet With an Ocean of Magma

It's the best evidence yet of an atmosphere on a rocky planet outside our solar system, researchers say, and studying the distant world could provide insight into Earth’s early days

A picture of the International Space Station captured by the Space Shuttle Discovery in 2007. Last month, a two-ton pallet of batteries released by the space station in 2021 re-entered Earth's atmosphere. It was expected to mostly burn up upon re-entry, but a two-pound piece of debris that struck a Florida home may have come from the batteries.
