Feature Guest: Smadar Naoz We’ve long known that most galaxies contain at their core a supermassive black hole that can be millions of times the mass of the sun. But now researchers are discovering galaxies with more than one supermassive black hole at their centre. To understand the implications of this discovery and what it could mean about the history of the Milky Way, should our own galaxy be among this collection, today we’re joined here at The Star Spot by astrophysicist Smadar Naoz. Current in Space Stars like the Sun are a no-brainer when it comes to finding habitable planets, but Amelia and Priyanka say another star is even better; say hello to the orange dwarf. In other habitable planet news, Jeff reports on the discovery of two super-Earth exoplanets that just may be home to life. Finally, Anshool looks to the ancient history of our own planet with the finding of the oldest known asteroid impact, one which may have marked a major climate shift. About Our Guest Smadar Naoz is Howard and Astrid Preston Term Chair in Astrophysics and Associate Professor of Physics and Astronomy at UCLA. She is a member of the executive committee of the Bhaumik Institute for Theoretical Physics. She received her PhD from Tel Aviv University before working as an Einstein Fellow at Harvard University.We’ve long known that most galaxies contain at their core a supermassive black hole that can be millions of times the mass of the sun.
