| Description |
English: This Chandra image of Sgr A* and the surrounding region was made from a 164 hours of observation time over a two-week period. During this time the black hole flared up in X-ray intensity half a dozen or more times. The cause of these outbursts is not understood, but the rapidity with which they rise and fall indicates that they are occurring near the event horizon, or point of no return, around the black hole. Also discovered were more than two thousand other X-ray sources and huge lobes of 20 million-degree Centigrade gas (the red loops in the image at approximately the 2 o'clock and 7 o'clock positions). The lobes indicate that enormous explosions occurred near the black hole several times over the last ten thousand years.
Slovenčina: Röntgenová snímka zo satelitu Chandra zachytáva jadro našej Galaxie v nepravých farbách. Táto snímka vznikla po zatiaľ najdlhšej röntgenovej expozícii (celkove 164 hodín). Čierna diera Sagittarius A* sa nachádza v najjasnejšej časti snímky. Veľké červené oblasti v pravom hornom a ľavom dolnom rohu sú laloky horúceho plynu s teplotou niekoľko miliónov °C, ktoré sú symetricky rozložené vo vzdialenosti niekoľkých desiatok svetelných rokov po oboch stranách čiernej diery. Tieto laloky sú dôkazom jednej, alebo viacerých explózii na horizonte čiernej diery, ku ktorým došlo v priebehu posledných 10 000 rokov. Na snímke bolo nájdených vyše 2 000 ďalších röntgenových zdrojov. |
