In April, the Sun will stop distribution the commands to Mars mission

The planets in the next month will worsen due to the Mars mission. Mars will be almost exactly behind the Sun when viewed from Earth. The sun can easily interrupt the broadcast between two planets when the three celestial bodies line up in one line. To prevent incorrect signaling, dispatchers from NASA Jet Propulsion Laboratory intend to suspend sending any commands to all the Martian rovers and orbiters in April. Transmission from Mars to Earth, too, will be kept to a minimum.

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.
