Analyzing the observations made using NASA’s Spitzer WISE space telescopes, many runaway stars were discovered. Those stars are called that way for the remarkable speed they’re moving at in space. One way to identify a potential runaway star is to seek what in jargon is called “bow shock” and indicates the area between a magnetosphere and a surrounding environment. It’s an arc-shaped structure that extends in front of the star and can be very extensive.
At the American Astronomical Society’s meeting in Kissimmee, Florida, astronomers presented the results of research that aims to understand how come the multiple systems of stars and planets from the material on the disks of dust around new stars. The radio telescope Karl G. Jansky Very Large Array (VLA) was used to study almost one hundred newborn stars in the Perseus molecular cloud to try to answer these questions.
The Hubble Space Telescope took a photograph of the galaxy NGC 4845. At its core, it contains a supermassive black hole, a fact now considered normal but that can be detected only indirectly, through the gravitational effects on stars near to the galactic core. During the observations, it swhoed a remarkable appetite as in 2013 it swallowed in a short time a mass several times that of the planet Jupiter.
NGC 6052 is a galaxy apparently abnormal because of its odd shape. It was initially classified in that way but later astronomers realized that it’s actually the result of an ongoing merger of two galaxies with similar masses. The Hubble space telescope was used to take a picture of NGC 6052 with its Wide Field Planetary Camera 2 (WFPC2), which includes observations in visible and ultraviolet light.
Today the new Roscosmos starts its activities as a state corporation that replaces the old Russian space agency, officially dissolved on December 28 2015 with a decree of President Vladimir Putin. It’s an important step in the reorganization of the Russian space program began in 2013 in an attempt to revamp it and above all to solve the problems it’s been suffering.
