Create a map with millions of unknown galaxies until now
A very advanced telescope
The ASKAP telescope, a collection of 36 satellite dishes that work together to capture panoramic views of the sky, mapped a total of three million galaxies, obtaining images with twice the level of detail of previous surveys, according to the CSIRO researchers. The result is a kind of “Google Maps” of the night sky that you can interact with and use to view details of remote parts of the known universe.
The data is publicly available, so scientists around the world could study “everything from star formation to how galaxies and their supermassive black hole evolve and interact,” commented David McConnell, project leader in his study collected. by the magazine Publications of the Astronomical Society of Australia.
What makes this telescope unique is its wide field of view, utilizing CSIRO-designed receivers that allow you to take panoramic photos with much sharper detail than before. Total, 903 images have been combined -with 15 minutes of exposure each one- to create this map of the southern sky (unlike other surveys that required tens of thousands of images).
“It’s more sensitive than previous studies that have covered the entire sky in this way, so we see more objects than we’ve seen in the past,” McConnell clarifies.
If we take a look at the map in question, it will be incredibly familiar. You will think that you are observing the night sky on a starry night but, almost all the bright spots you will be seeing will not be stars, but entire galaxies.
