Galaxy pyrotechnic of 23 million light-years away, Galaxies around 23 million light-years away are impressive and sustainable fireworks. Instead of paper, dust and fire, this galaxy’s light show contains large black holes, shock waves and large gas tanks.
This galactic firework display takes place at NGC 4258, also known as M106, a spiral galaxy like our Milky Way.
However, this galaxy is known because our galaxy does not have two additional spiral arms that glow in X-rays, optics, and radio light. These features or abnormal arms are not parallel to the plane of the galaxy, but are tangent to it.

 Abnormal shoulders are visible in this new composite image, where X-rays from NASA’s Xander Observatory are blue, enormous radio data from NSF Carl Jansky are purple, and optical data from NASA’s Hubble Space Telescope are yellow and infrared. NASA’s Spitzer Telescope is red.
A new study by Spitzer shows that shock waves, such as aircraft arrows, heat large amounts of gas, which is equivalent to about 10 million suns.
The researchers believe that the super-massive black hole at the center of NGC 4258 produces strong rays of high-energy particles. These jets hit the galactic disk and produce shock waves. This shock wave in turn heats up the gas, which is mainly composed of hydrogen molecules, up to thousands of degrees.
Chandra X-rays show large bubbles of hot gas above and below the plane of the galaxy. These bubbles indicate that most of the gas originally contained in the galaxy disk is heated by black hole radiation and released into the outer region.
Expulsion of gas from discs from jets is important to the fate of this galaxy. The researchers believe that all the remaining gas will be emitted in the next 300 million years – immediately on a cosmic time scale, if not refilled in a certain way.
Because most of the gas in the disc has been ejected, there is less gas to form new stars. In fact, the researchers used loudspeaker data to estimate that stars had formed in the central area of ​​NGC 4258 at a speed of about ten times slower than in the Milky Way.
The Herschel Space Observatory space observatory is used to confirm estimates of low star formation data from speakers in the central region of the NGC 4258 galaxy,
After infrared emissions caused by a collision can increase significantly, the researchers found that the gas mass was ten times smaller than previously calculated.
Because NGC 4258 is relatively close to Earth, astronomers can study how this black hole affects galaxies in detail.
