A millisecond is a thousandth of a second, and a nanosecond is a billionth of a second, but there’s another measurement of time that makes both of them look slow.
Scientists have for the first time been able to measure something in a zeptosecond, or a trillionth of a billionth of a second.
Laser physicists in Munich fired an extreme ultraviolet light pulse onto a helium atom to excite the electrons, causing one to break free ― a process called photoemission. At the same time, they shot an infrared laser pulse to detect the electron as it left the atom.
That’s when it happened.

On Nov. 14, skywatchers will be treated to a supermoon so big and bright that it’s being billed as a “super-dupermoon” or an “extra-supermoon.”
Supermoons aren’t especially uncommon, but this will be the nearest that a full moon has come to Earth since January 26, 1948. The full moon won’t get this close again until November 25, 2034.
The term supermoon refers to a full moon that occurs when our planet’s natural satellite is at its closest point to Earth in its elliptical orbit. Astronomers call that point perigee, and so “perigee moon” is another term for supermoon. (The point at which the moon is most distant from Earth in its orbit is known as apogee.)
A supermoon can appear up to 14 percent bigger and 30 percent brighter than an apogee full moon, according to NASA. The effect is most pronounced when the moon is viewed near the horizon.
