A modelling study suggests marine cloud brightening could shade the eastern Pacific and reduce a global temperature spike from El Niño, but there could be unexpected consequences

A drug that softens the ovaries helped mice and rats conceive more easily at an older age, and produce more pups

Seeking out the simplest, most elegant explanations has served scientists well for centuries, but cognitive scientist Marina Dubova’s experiments are revealing better ways to uncover reality

We might be living through a comet shower created by a star that millions of years ago jostled the Oort Cloud surrounding the solar system.

This image from NASA's Hubble Space Telescope shows Messier 3, a densely packed cluster of stars whose origins may be a merger between globular clusters in the early universe.

This image from NASA’s Hubble Space Telescope showcases Messier 3 (M3), one of the Milky Way galaxy’s most massive globular clusters, or spherical collections of gravitationally bound stars. Globular clusters are made up of ancient stars that formed at roughly the same time from the same cloud of gas, giving those stars similar ages. Around 150 known globular clusters are sprinkled around the outer regions of the Milky Way.
