Space Telescope
European Space Agency's XMM-Newton helped discover a star and a black hole that
address near each other at high speed, making one revolution in just 2.4 hours
- which is an hour shorter than the orbital period of the previous record holder.
A black hole in the
close pair, known as the MAXI J1659-152, at least three times as massive as the
Sun, while the mass of its companion star - a red dwarf star - only 20% of the
solar mass.
