New Meteor Shower in the Constellation Cassiopeia
SETI Institute
Leading humanity's quest to understand the origins and prevalence of life and intelligence in the universe...
In the early morning of September 4, there was a brief meteor shower outburst visible over California and Arizona with a radiant in the constellation Cassiopeia. It was recorded by low-light video cameras in the CAMS networks led by Peter Jenniskens (SETI Institute) and Nick Moskovitz (Lowell Observatory). The outburst revealed a weak annual shower that had not been mapped before, with a possible earlier outburst in 2014. The shower was caused by the crumbs of a yet-to-be-discovered comet in a high-inclined orbit.

SETI Live Replay: Finally! An Intermediate-Mass Black Hole
There are supermassive black holes. There are stellar mass black holes. And based on the idea that galaxies evolve as they merge, there should be black holes in between -- intermediate-mass black holes. However, finding these middle-of-the-road beasts has been difficult. Now, a new paper in Nature identifies the first-ever mid-size sedan in a universe of compact cars and SUVs. This black hole resides in the center of the Omega Centauri star cluster, which is thought to be the core of a galaxy that merged with the Milky Way billions of years ago.
