SGR 1900 + 14 is a soft gamma repeater , which is located in the constellation eagle , around 20,000 light years from Earth.

It is assumed that the SGR 1900 + 14 is a magnetar that may have been created by a supernova relatively recently. A gamma-ray flash was registered on August 27, 1998, and shortly afterwards a new source of electromagnetic radiation appeared in this region of the sky. The NASA telescope Spitzer discovered in 2005 and 2007, two closely spaced rings in the infrared range. The rings measure about 7 light years in diameter . The origin or cause of the rings is currently unknown.

The gamma-ray flash mentioned at the beginning had a significant impact on the earth's atmosphere despite the great distance of 20,000 light years . The atoms of the atmosphere are usually ionized by the sun during the day and lose them again at night. After the flash, however, they were almost at the same level as during the day by the sun, also ionized at night, this time by the gamma-ray flash. The Rossi X-Ray Timing Explorer , an X-ray satellite received at this time, although he was aligned in a different direction of the sky, and this signal.
