Blue 'dots"

    In the top galaxy are many blue areas. Is this gravitational lensing?

    Welcome to Galaxy Zoo, renatevos! 😃

    This is an Illustris simulation (read more about the fascinating project here). In these simulations, gravitational lensing is impossible, unlike in the real universe. The blue blobs are simulated star-forming regions, in this case within the (simulated) galaxy towards the top.

    Hope this helps, and happy hunting! 😄
