  • Ultra-hot, young stars can sometimes form jets, like this Herbig-Haro object in the Orion Nebula,... [+] just 1,500 light years away from our position in the galaxy. The radiation and winds from young, massive stars can impart enormous kicks to the surrounding matter..The Crab Nebula, as shown here with data from five different observatories, shows how material gets... [+] ejected from a supernova. The material shown here spans about 5 light-years in extent, originating from a star that went supernova about 1,000 years ago, teaching us that the typical speed of the ejecta is around 1,500 km/s.
  • A galaxy that was governed by normal matter alone (L) would display much lower rotational speeds in... [+] the outskirts than towards the center, similar to how planets in the Solar System move. However, observations indicate that rotational speeds are largely independent of radius (R) from the galactic center, leading to the inference that a large amount of invisible, or dark, matter must be present. What isn't greatly appreciated is that without dark matter, life as we know it would not exist.
