Black holes are already mind-bending enough. Matter and energy compressed into a region so dense that the escape velocity exceeds the speed of light. Places where space and time are tangled up so much that even if you could go faster than light speed, you’d still end up at the singularity. Astronomers know of two kinds of black holes in the Universe: stellar mass and supermassive, and how we get them have been worked out pretty well. But there’s a third class of black hole, one which has never been observed nor detected indirectly, and yet it could explain some of the mysteries of the Universe, including the nature of dark matter. Primordial black holes.

24-OCT UPDATE: We are postponing tonight's VSP in lieu of the CosmoQuest Hangout-A-Thon. If you are so inclined, please tune into the HAT on Twitch for science, fun, and giveaways: https://www.twitch.tv/cosmoquestx THANKS IN ADVANCE!!! 17-OCT UPDATE: Again we are going to have to delay VSP 10 due to poor conditions and prior commitments. Cross your fingers and check back in one week! 10-OCT UPDATE: Once again most of our scopes are experiencing cloudy conditions, so we are postponing VSP 10 by another week. We will try again on Saturday, 17-OCT. Have a good week all. NOTE: Due to less than optimal viewing conditions on the West Coast of the US (where many of our streamers are location) due to the wild fires, we are forced to once again postpone our VSP for one week. Hope to see everyone on the 10th! NOTE: Due to its once again getting dark earlier here in the Northern Hemisphere , beginning this week we are starting the VSPs ONE HOUR EARLIER! Join Fraser for the Virtual Star Party and observe the night skies from locations around the world. We are working to line up a great team of astronomers to show everyone the view of their local skies. And if conditions are good, Fraser will also be sharing the sky from Landers, CA!

THIRD TIME'S A CHARM! Conditions are FINALLY looking good for tonight (26-SEP) so hope to "see" everyone in a few hours! UPDATE 2: Due to weather conditions and other unforeseen circumstances for many of us, we are again postponing our first stream by one week. UPDATE: Due to the ongoing wildfire situation in California it is not possible for many of our scopes to do any viewing. Therefore we are postponing our Season Premiere for one week in the hope that conditions will improve. To all of our streamers and viewers impacted by the wildfires, please stay safe. ******************************** Join Fraser for our Season's Premiere of the Virtual Star Party and observe the night skies from locations around the world.
