Q0906+6930 was the most distant known blazar (redshift 5.47 / 12.2 billion light years) at the time of its discovery in July, 2004. The engine of the blazar is a supermassive black hole (SMBH) approximately 2 billion times the mass of the Sun (the mass of the Milky Way Galaxy is around 1.5 trillion solar masses). The event horizon volume is on the order of 1,000 times that of the Solar System. It is one of the most massive black holes on record.

HAT-P-13, also known as GSC 03416-00543, is a G-type main sequence star approximately 800 light-years away in the constellation Ursa Major. In 2009 it was discovered that this star is orbited by two massive planets, the innermost of which transits the star. This was the first known example of an extrasolar transiting planet with an additional planet in the same system.
