Milky Way's black hole goes bang powerful flash

For unknown reason, the black hole (BH), located in the center of our Milky Way galaxy, regarding once a day generates an X-ray flash. Such outbreaks last for several hours, and their brightness can in some cases exceed the normal brightness of the black hole, even a hundred times. But in February 2012, astronomers using the X-ray Observatory "Chandra", recorded the most powerful flare ever observed on the central black hole in our galaxy known as Sagittarius A *.

The team switched from Mars Curiosity time on earth

After three months on "Martian time," a team of scientists, which supervise NASA's Mars rover Curiosity, went to work on a standard work schedule, "Earth time."

Martian day, called "Salt", lasts for 40 minutes longer than the earth, so the beginning of the shift to the members of the scientific team was shifted a few hours each week in advance. Rover team includes more than 200 engineers from the Jet Propulsion Laboratory of NASA and about 400 researchers, mainly from other academic institutions.

Unusual lunar crater will help to understand the evolution of craters on Earth

Researchers studying the evolution of impact craters on Earth and other rocky bodies discovered an interesting object for research on the moon.

Scientists engaged in the crater of lunar   who is in the region known as the lunar Sea of Tranquility. The crater is only 2.2 kilometers in diameter, but it is very young - formed only 10 million years ago - and well-preserved.
