Today, Hubble is celebrating its 21st birthday. (Technically, Hubble was launched aboard the Space Shuttle Discovery on April 24, 1990. But it’s sort of like having a kid’s birthday fall during the week of or on Christmas – you just need to have a party when everyone is available.) The beautiful part about Hubble’s birthday is that we are the ones that get the gift: a new image of the interacting galaxies known as Arp 273.
Happy Birthday, Fellow Great Observatory.
Great Observatories: CGRO, Chandra, Hubble, Spitzer
