A video that attempts to show just how massive the universe is has left many convinced we can’t be alone in the universe. Admittedly, I am not an astronomer, but I reckon space is pretty big. A vacuum so vast that some social media users have been convinced that humans cannot be alone in the…

As a NASA astronaut, Mike Massimino spacewalked four times to repair the Hubble Space Telescope. When he retired in 2014 and began giving talks about his experiences, he assumed audiences would want to hear about the thrills of those exploits. Instead, he found himself fielding questions that were broader and deeper: How did he weather…

Galaxies like our Milky Way are mysteriously hard to come by in our cosmic backyard. New supercomputer simulations have helped astronomers finally answer why. The Milky Way sits within a galaxy cluster on the Supergalactic Plane — a billion light-year-wide sheet, or “supercluster,” upon which large galaxy clusters are pinned. But other spiral galaxies are…

When galaxies merge, we expect them to produce binary black holes (BBHs.) BBHs orbit one another closely, and when they merge, they produce gravitational waves that have been detected by LIGO-Virgo. The upcoming Vera Rubin Observatory should be able to find them before they merge, which would open a whole new window into the study…

There are a whole bunch of telescopes on sale for Black Friday. However, if we were to choose one that will be the best choice for most people, it’s the Celestron AstroFi 102. While it isn’t the cheapest or most feature-packed telescope you’ll see, it combines performance with price extremely well, and you can currently…
