Nanometer-scale growth of cone cells tracked in living human eye

Humans see color thanks to cone cells, specialized light-sensing neurons located in the retina along the inner surface of the eyeball. The actual light-sensing section of these cells is called the outer segment, which is ...

A laser beam's path through NASA's ICESat-2

Before beaming 300 miles to Earth's surface, bouncing off the ground and travelling another 300 miles back into space, the laser photons on NASA's Ice, Cloud and Land Elevation Satellite-2 first have to complete a 7½-foot ...

Image: A ghost in the Pleiades

This ghostly image shows what can happen when an interstellar cloud passes too close to a star. Barnard's Merope Nebula, also known as IC 349, is a cloud of interstellar gas and dust traveling through the Pleiades star cluster ...
