Scientists have noticed a rare "runaway" star, accelerating across the galaxy with an indicator of 300,000 miles per hour. The object (J01020100-7122208) is located in the Small Magellanic Cloud and was once a member of the double star system. When a neighbor exploded in the form of a supernova, the energy surge pushed the star into space at high speeds. This is the first escaping yellow supergiant and the second escape event found in another galaxy.
After 10 million years of space travel, the star turned into a yellow supergiant. The journey took 1.6 degrees in the sky, which is three times the diameter of the full moon. The star will continue to accelerate until it explodes as a supernova (after about 3 million years). When this happens, a portion of heavy elements will be thrown into space, which will make it possible to form new stars or planets on the outer edge of the galaxy. The stars were found using the 4-meter Blanco telescope of the National Optical Astronomical Observatory and the 6.5-meter Magellan telescope (Chile). Yellow supergiants are considered rare objects, because the duration of this phase takes a little time. Then they expand into red supergiants, like Betelgeuse, and die in the form of supernovae.
