As Enrico Fermi famously once said, “Where is everybody”?” These words were uttered in the summer of 1950 when the search for extraterrestrial intelligence (SETI) was heating up. They also captured the frustrations and unresolved questions surrounding the existence of extraterrestrial life.
The last time we were in this position in the Milky Way, dinosaurs were just beginning to roam the Earth.
Nine human species walked the Earth 300,000 years ago. Now there is just one. The Neanderthals, Homo neanderthalensis, were stocky hunters adapted to Europe’s cold steppes. The related Denisovans inhabited Asia, while the more primitive Homo erectus lived in Indonesia, and Homo rhodesiensis in central Africa.
Astronomers note record-breaking observation of highest energy ever measured from gamma ray bursts
A shocking discovery made a decade and a half ago is changing our understanding of human evolution
In a first, an international team has found sugars essential to life in meteorites.
NASA is about to put a rover to the test in Antarctica, and it’s unlike any robot the agency has ever shot into space.
Meteorologists give names to large storms with wide impacts — like tropical cyclones and, in some cases, massive winter storms — to help make communication easier. If you have several active tropical storms, for instance, you want to be sure everyone knows which one you’re discussing.
It is a well-known astronomical convention that Earth has only one natural satellite, which is known (somewhat uncreatively) as “the Moon”. However, astronomers have known for a little over a decade that Earth also has a population of what are known as “transient Moons”. These are a subset of Near-Earth Objects (NEOs) that are temporarily scooped up by Earth’s gravity and assume orbits around our planet.
