Astronomers have found a #FRB that repeats on a regular cycle. Every 16.35 days, the signal named FRB 180916.J0158+65 follows a similar pattern. For four days, it will spit out a burst or two every hour. Then it falls silent for 12 days. @ScienceAlert

Kalpana Chawla (17 Mar 1962 – 1 Feb 2003) was an astronaut and engineer and the first woman of Indian descent to go into space. Tragically, she was one of the seven astronauts aboard the Space Shuttle Columbia when it was destroyed upon re-entry. #AAPIHM

The weird hexagon swirling around Saturn's north pole is much taller than scientists had thought, a new study suggests. The bizarre structure actually extends about 180 miles (300 km) above the cloud tops, up into the stratosphere. | @SPACEdotcom @esa

#PPOD : This image was the winning entry in last year's Astronomy Photographer of the Year competition. Taken from France, the crescent world is Venus just before the Moon passes in front of it. @NLefaudeux used a Celestron C11 2800mm telescope to capture this moment. #photography
