Enceladus, a small moon that orbits in the E-ring of the planet Saturn, has provided a number of surprising astronomical discoveries in recent years. A new report shows it once again defying expectations. Researchers at NASA's Jet Propulsion Laboratory have found that it produces far more heat than they ever predicted.

Has alien life really been found on a meteorite?

A recent title in Nature News provides a succinct answer: "The aliens haven't landed."¹ The article offered a sweeping refutation of NASA scientist Richard Hoover's claim that extraterrestrial microscopic bacteria fossils were found in a carbonaceous meteorite.

Researchers have constructed a new evolutionary tree for flies that purports to show which types of fly likely evolved into other types.

If complicated living things arose through eons of evolution, and if lower rock layers represent the earth long ago before those eons occurred, then complicated life forms should only exist near the top―after evolution had enough time to accidentally develop them. But what would happen to belief in biological evolution if complicated life forms were among the fossils in the bottom layers?

The chambered nautilus, also known as the pearly nautilus, is a mollusk with a beautiful, symmetrical shell that is divided into buoyancy-controlling chambers. Few of these amazing sea creatures remain, apparently due to over-harvesting because their shells are popular novelties.
