The Carina Nebula (a stellar nursery 8500 light years from Earth) as imaged by Hubble

The Fourth of July was on a perfect summer Sunday this year and we failed to celebrate with a gallery of images. Therefore, in a belated salute to our great-but-troubled union, here are some of the all-time best photographs taken from the Hubble Space telescope, the world’s premier orbital telescope, Hubble launched in April 24, 1990 and has provided an astonishing window on the universe since then (despite some glitches which have cropped up from time to time), however now both the main computer and the backup computer are malfunctioning.

Hubble was designed to be periodically serviced by a space shuttle and its friendly crew of astronauts, however, since the shuttles have been permanently retired, scientists are now stuck trying to fix the aging legacy systems from 400 kilometers away. Although there are various reset combinations left to try, some astronomers and technicians are starting to wonder if the Hubble era is coming to an end.

Although Hubble’s troubles are dominating space telescope news at the moment, it is no longer the only story. The long-delayed James Webb telescope is finally getting close to launching (blast-off is set for November). That scope is to Hubble, what Hubble was to its earth-bound predecessors (which is to say, it is orders of magnitude more powerful and sophisticated). We will be talking about Webb in November, but for right now let’s celebrate the warm summer nights with Hubble’s cosmic gallery of astonishing celestial fireworks.

The giant red nebula (NGC 2014) and its smaller blue neighbor (NGC 2020): The glowing center of the red nebula is a nursery of stars 10-20 times more massive than the sun. The blue nebula is a bubble of ionized hydrogen ejected by the super luminous blue star in the center.
