Running a tech startup is a challenging endeavour under any circumstances. Imagine doing it under invasion with air raid sirens going off on average twice every 24 hours — and managing to grow 250% in the process.  This is the story of OBRIO, a Ukrainian startup behind the successful astrology app Nebula. Speaking to TNW from his apartment in Kyiv just before the turn of the year, founder and CEO Alex Fedorov says that running a company during wartime is not exactly something you learn in…

The Running Chicken Nebula comprises several clouds, all of which we can see in this vast image from the VLT Survey Telescope (VST), hosted at ESO’s Paranal site. This 1.5-billion-pixel image spans an area in the sky of about 25 full Moons. The clouds shown in wispy pink plumes are full of gas and dust, illuminated by the young and hot stars within them.

A little more than 969 years ago—on July 4, 1054, to be more precise—the light from one of the universe’s most energetic and violent events reached Earth: a supernova, or exploding star. Although its source was a soul-crushing 6,500 light-years from us, the supernova’s light was so bright that it could be seen in daytime for weeks. Various civilizations around the world documented its appearance in records from that time, which is how we know the very day it occurred. Hundreds of years later, astronomers observing the…
