The Vera C. Rubin Observatory has taken another step towards first light, projected for some time in 2022. Its enormous 3200 megapixel camera just took its first picture during lab testing at the SLAC National Accelerator Laboratory. The camera is the largest ever built, and its unprecedented power is the driving force behind the Observatory’s ten year Legacy Survey of Space and Time (LSST).Continue reading “Vera Rubin’s Monster 3200-Megapixel Camera Takes its First Picture (in the Lab)”
A comet-eating black hole the size of a planet? It’s possible. And if there’s one out there in the distant Solar System, a pair of researchers think they know how to find it.
If they do, we might finally put the Planet 9 issue to rest.Continue reading “If Planet 9 is a Primordial Black Hole, We Might Be Able to See Flares When it Consumes Comets”
When Canadian astronomer Robert Weryk discovered `Oumuamua passing through our Solar System with the Pan-STARRS telescope, in October 2017, it caused quite a stir. It was the first interstellar object we’d ever seen coming through our neighbourhood. The excitement led to speculation: what could it be?
There was lots of fun conjecture on its origins. Was it an alien spacecraft? A solar sail? Or something more prosaic?Continue reading “Interstellar Oumuamua Was a Dark Hydrogen Iceberg”
The U.S. House of Representatives have passed a bill to change the name of the Large Synoptic Survey Telescope (LSST.) Instead of that explanatory yet cumbersome name, it will be named after American astronomer Vera Rubin. Rubin is well-known for her pioneering work in discovering dark matter.Continue reading “Great News! The Large Synoptic Survey Telescope Might be Named for Vera Rubin”
