An international team of astronomers from Chile and Germany has managed to capture an image of unprecedented detail of another star — that isn’t the Sun — the red supergiant star Antares. The team has also made the first map of the velocities of material in the atmosphere of a star other than the Sun, revealing unexpected turbulence in the extended atmosphere of Antares. Antares, also designated Alpha Scorpii, is a well-studied, close red supergiant star at a distance of 554 light years. It is the fifteenth-brightest star in the night sky and the brightest star in the constellation of Scorpius. With a diameter about 700 times that of the Sun and a mass about 12 times solar, Antares is one of largest stars. This is the most detailed image ever of the red supergiant star Antares, or any other star apart from the Sun. Image credit: K. Ohnaka / ESO. It is thought that Ant...

However, once prevailed upon to investigate, the police found what could not be mistaken for anything oth...

CHINA REACHES THE MOON SNAPPING INCREDIBLE, NEVER-BEFORE-SEEN HIGH-DEFINITION IMAGES

Image
While investigating the lunar surface, China's Chang'e 3 lander found another sort of moon shake, and figured out how to snap THOUSANDS of high-determination pictures of the moon.  Interestingly, you can take a look at the lunar surface more than ever because of the complex cameras found locally available the Chang'e 3, one of China's most progressive lunar landers. The Lunar Mission touched down on the moon in 2013, on the area known as Mare Imbrium – where scientists have faith in the inaccessible past, genuine water could have existed—making China the third nation in the historical backdrop of humankind to accomplish a delicate arriving on the lunar surface, after the Soviet Union and United States of America.  While the mission occurred in 2013, China's National Space Administration discharged a huge number of the top notch pictures amid 2015. The pictures in any case, weren't shown by western media because of the way that China is utilized to di...
