Oops, they did it again…!

LIGO_graphic(Well, not really oops… It’s deliberate.) LIGO has announced another gravitational wave detection from a black hole merger! This time the black holes were 14.2 and 7.5 times the mass of the sun, and merged to form a new black hole of mass 20.8 times the mass of our sun, releasing a burst of energy in gravitational waves picked up by the detectors on December 26th last year. They’ve been analyzing their data run for a while, found this signal, and announced the result today at the American Astronomical Society’s annual meeting in San Diego. There’s a lot more about it in this MIT News article I found. (See my earlier post on the first detection.) (Update: NPR Piece here.)

This is exciting, as it continues to show that we’re on the cusp of a new era of gravitational wave astronomy!

    Hi Prof. Johnson. Apologies for the off-topic post, but why is the following page part of your website ?

    I’m quite sure you are not associated with bitcoin sales of online meds so I thought I’d check with you. Google actually has this page indexed as part of your searchable site.

    Yikes!! I’ve no idea how that got there. Must be some clever robot invasion of my site. Now I must try to figure out how to clean out this and other stuff from the site… ugh.

    THANKS!

    Found a few hundred or so such things selling all sorts of awful things embedded in the blog. Don’t know how they could have got there. Removed them… wonder what I missed?… Geez. Thanks for pointing this out!
