Star and a black hole revolving in rapid waltz

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.

Because of the awaiting solar storm on March 7 NASA temporarily balanced operations on the Martian surface rover Curiosity Mission Mars Science Lab (MSL). Currently, the rover mission scientists have presumed from the "sleep" mode, because the power of the solar storm was much lower than expect.

NASA has taken protection in view of the fact that a large coronal mass ejection, presumably, was to reach Mars in a few days, from March 7, the researchers say.
