According tomedia reports, the image below looks like a firework exploding in mid-air, but it is actually a distant collection of stars called NGC 1805. This is the ball cluster. The image, taken by NASA’s Hubble Space Telescope, is a good example of why space telescopes are so important to our understanding of space, in addition to showing a gorgeous cluster of space stars.
As The Hubble website explains, the cluster is a dense collection of stars. It is understood that the distance between these stars is “100 to 1000 times” the distance between other stars and the sun, which is very incredible.
So many stars occupy an area, and what kind of planets are orbiting them. But the Hubble team says the likelihood of planets orbiting them is low. According to scientists, the planets orbiting stars are unlikely to exist when they form and are so close together.
As for the color changes you see in the image, it’s actually a by-product of how the image is captured and the difference in the star itself. Stars shown in the images are detected by near ultraviolet light, burning at higher temperatures than orange and red stars, which emit more near-infrared light. And we can see all these stars thanks to Hubble being a space telescope, not a ground-based telescope.
The Earth’s atmosphere is very good at absorbing most of the ultraviolet rays. Some ultraviolet light can still pass, but ground-based telescopes can’t capture the image like space telescopes do. The Hubble telescope can detect ultraviolet and infrared light without having to deal with the Earth’s atmosphere, creating a clearer picture of this particular area of space.
