The galaxy is also home to numerous large supermassive black holes which are often just as big as our Sun. Here are six images of the black hole, which was discovered last October, showing a strong signature of radiation, about 50.7 billion times brighter than it should be given the distance to the central black hole.
The image shows how distant this object is from the centre of the Milky Way, and how massive it is. The source of the radiation is a jet of material from the galactic centre which has stretched out to fill this particular location. Other than that, nothing special happens but the image clearly shows that it cannot be there naturally. Here is another image of the black hole in space. When the source is too close (the red line), the glare of a foreground light source is too strong to be seen. When it is too far away (the blue line), such a shadow is produced, and we can see a jet of bright material streaming towards the black hole. The jets are produced by collisions of supermassive black holes in galaxy clusters. The image shows the position of the black hole, which can be seen in the bottom-left corner of the panel. It is located at 3.2 million light years from Earth. It is also about as far away as is possible given our limited solar system. Here is an additional image of the galaxy. It has been created using Hubble’s Advanced Camera for Surveys. The light from this galaxy is coloured red, indicating it comes from the nearby galaxy NGC 1337. We see that NGC 1337 itself has a massive black hole which is also the most massive one known. The image can be seen here , but you should also turn on your low-light setting if possible before seeing the image.
Now for a view of the Milky Way galaxy in the night sky using the Hubble Space Telescope’s Space Telescope Imaging Spectrograph (STIS). The image above shows the Milky Way in full daylight as viewed by Hubble via the STIS Telescope in 2011. When looking away from the central black hole from the centre of the galaxy, the light is blue and the image has been corrected for the effect of the Earth’s atmosphere by reducing the brightness of an observer’s eye. The image shows the location of the central black hole from which a jet stream of material is moving towards the galaxy – similar to how the jets are produced by collisions of supermassive black holes in clusters. While that is the case, it is clearly not the case for the black hole because it is situated so far off the central black hole’s star. The black hole is just one of over 2 billion such objects in the centre of the Milky Way galaxy. The star is located just inside the circle for the Milky Way galaxy. Here is one of the images of the Milky Way galaxy from Hubble in 2012. The red line shows the position of the black hole. The yellow line shows the location of the stars in the galaxy, and where you can see the Earth and the Milky Way. The image is shown in colour here.
Back in the day, before we can look forward to another galaxy, we need to understand the nature of our own galaxy. The image below was made using Hubble’s Wide Field Camera 2 to map the stars in the centre of the Milky Way galaxy. Unlike its neighboring galaxies, the Milky Way is full of clouds of galaxies. The image shows the positions of each of these many clouds. It is important to note that we see clouds in that part of the galaxy because galaxies are moving away from their parent and forming a group, and those are moving towards an observer’s location. However, it is possible to look inside the galaxies and see what the individual stars are doing about that separation. So in the image above, the brightest stars are shown from the dust-loaded central regions towards that observer, all the way out to the edge of the dust cloud and so on. The dust clouds are made up of galaxies that are young and are colliding together to form new galaxies. These collisions are creating the bright and white star-light, because the most massive and energetic of these events are not seen by us as they are far from us due to the massive distortion of space that the galaxies undergo as they are torn apart. As the galaxies interact with each other, there’s a lot of dust and gas from the collision that we can see from here, but because of their size and their fast motions we cannot see much below us.
Back in the day, before we could ever see this image, here is another view showing the position of the black hole. Although the centre of the galaxy is very distant from the observer (around 300,000 light years) it, together with every other galaxy, is extremely luminous. The image shows the brightness of the centre of the galaxy, as captured by Hubble’s Advanced Camera for Surveys Survey in 2010. This is the centre of the Galaxy, surrounded by the entire galaxy. There are thousands more galaxies
