Conventionally, the moon is thought to have formed during one big impact, but a three-impact model might make more sense

To celebrate 25 years since the completion of the International Gemini Observatory, students in Chile voted for the Gemini South telescope to image NGC 6302 — a billowing planetary nebula that resembles a cosmic butterfly. The International Gemini Observatory is partly funded by the U.S. National Science Foundation (NSF) and operated by NSF NOIRLab.

A rapidly intensifying low-pressure system off the coast is keeping the worst of the snow away from Boston, New York City and Washington, D.C.

The famous double-slit experiment brings into question the very nature of matter. Its cousin, the quantum eraser experiment, makes us question the very existence of time – and how much we can manipulate it

The waxing gibbous Moon rises above Earth’s blue atmosphere in this photograph taken from the International Space Station as it orbited 263 miles above a cloudy Atlantic Ocean off the coast of Quebec, Canada.

Why is the Universe filled with matter? Why isn't it an equal amount of matter and antimatter? We still don't know the answer, but a new approach looks at the symmetries of extended models of particle physics and finds a possible path forward. It's a knotty problem that may just have a knotty solution.

Scientific American hosted an event at Morehouse School of Medicine to highlight medical advances in treating sickle cell disease and how far we still have to go

Two clashing ideas about disorder inside black holes now point to the same strange conclusions, and it could reshape the foundations of how we think about space and time
