Eight CubeSats and one payload supported by the European Space Agency (ESA) reached orbit, where they will demonstrate various applications aimed at improving how data is sent around and processed. Thanks to these demonstrations, practical and – sometimes – even life-saving data enabled from space will move more efficiently and reach the right actors on time in the future.
It's not often that astronomers can observe huge changes in a galaxy's brightness over the course of a few years. Most galaxies change in brightness (and other characteristics) over millions or billions of years. So, when images of the 10-billion-light-year distant galaxy J0218-0036 showed that it dimmed down by a twentieth of its previous brightness in just 20 years, observers were surprised. What could cause it to do that? That's not "normal" for AGN.
