Feature: Every second counts to trace a gravitational wave
Mar 23, 2018 (XNA)
"In an era of multi-messenger astronomy, we have to shorten the time as much as possible so as to trigger the alert quickly enough for follow-up observations," ...
Astronomers discover galaxies spin like clockwork
Mar 14, 2018 (SPX)
The Earth spinning around on its axis once gives us the length of a day, and a complete orbit of the Earth around the Sun gives us a year. "It's not Swiss watch...
Transportable optical clock used to measure gravitation for the first time
Feb 13, 2018 (SPX)
Until now, such delicate clocks have been restricted to laboratories at a few major research institutions, however, researchers at PTB have developed a transpor...
New method enables high-resolution measurements of magnetism
Feb 13, 2018 (SPX)
