Stuck at home with clear skies? We're all in a similar situation, as the ongoing pandemic sees most of the worldwide amateur astronomy community observing from home or from their backyard. One astronomical sure-fire even...

Colliding black holes aren't always as evenly matched as scientists expected, according to a cosmic chirp astronomers have puzzled over for a year.

The expectations of the gravitational-wave research community have been fulfilled: gravitational-wave discoveries are now part of their daily work as they have identified in the past observing run, O3, new gravitational-...

Governments throughout the world use rockets to launch satellites and people into orbit. This currently requires a lot of high-energy fuel, which is 95% of total rocket mass. Because the launch cost of a rocket can reach...

A galactic visitor entered our solar system last year--interstellar comet 2I/Borisov. When astronomers pointed the Atacama Large Millimeter/submillimeter Array (ALMA) toward the comet on 15 and 16 December 2019, for the ...

I was supposed to travel to "Mars" this month. The plan was to stay two weeks at the Mars Desert Research Station - actually in the Utah desert--to simulate human operations on the red planet. Eight of us were to live in...

ESA's cubic-metre-sized Proba-V minisatellite will soon end its nearly seven-year global mission to monitor the daily growth of all Earth's vegetation. As Copernicus Sentinel-3 takes on this task instead, Proba-V will be...
