Explanation of the above image: Centaurus A is the fifth brightest galaxy in the whole sky, creating it a perfect aim for amateur astronomers, and is also well-known for the dust track across its middle and a giant jet blasting away from a supermassive black hole at its core. Centaurus A is an active galaxy and is about 12 million light years from Planet Earth.
The Chandra X-Ray Observatory lately released four of the most spectacular pictures of galaxies. These four pictures are the most spectacular pictures of galaxies that we've ever seen, but these mind-blowing images couldn't have derived into reality without the help of amateur photographers and astronomers.
According to the Chandra X-Ray Observatory website, these four galaxy pictures came about because of an extraordinary teamwork with unprofessional astrophotographers. Here are exact words of Chandra X-Ray Observatory website:-
“What happens when the work of amateur astronomers and astrophotographers is combined with the data from some of the world's most sophisticated space telescopes? Collaborations between professional and amateur astronomers reveal the possibilities and are intended to raise interest and awareness among the community of the wealth of data publicly available in NASA's various mission archives. This effort is particularly appropriate for this month because April marks Global Astronomy Month, the world's largest global celebration of astronomy.
The images in this quartet of galaxies represent a sample of composites created with X-ray data from NASA's Chandra X-ray Observatory, infrared data from the Spitzer Space Telescope, and optical data collected by an amateur astronomer. In these images, the X-rays from Chandra are shown in purple, infrared emission from Spitzer is red, and the optical data are in red, green, and blue. The two astrophotographers who donated their images for these four images — Detlef Hartmann and Rolf Olsen — used their personal telescopes of 17.5 inches and 10 inches in diameter respectively. More details on how these images were made can be found in this blog post.”
Take a look at three more stunning galaxy images below, joining optical data from Spitzer's infrared data and Hartmann and Olsen wiht Chandra's X-ray data:
M81 is a spiral galaxy and is about 12 million light years away from planet Earth. It is both relatively large in the sky and bright, creating it a common target for both professional astronomers’ amateur astronomers.
M101 is a spiral galaxy just like our Milky Way Galaxy, but about 70% bigger than Milky Way. It is situated about 21 million light years from Planet Earth. Infrared data from Spitzer shows covered in dust lanes in the galaxy where stars are developing, while optical data traces the light from other stars.
M51 is one more spiral galaxy and is about 30 million light years away from Planet Earth. M51 is in the course of merging with a smaller galaxy seen to its upper left.
