Credit the jolly elves at Space Telescope Science Institute's Office of Public Outreach in Baltimore for these fun pics. NASA hired them to spread the joy of the Hubble Space Telescope's discoveries.
Above is dark matter in the center of the giant galaxy cluster Abell 1689, containing about 1,000 galaxies and trillions of stars (source: Hubble website). More Hubble pics below:
Above right, "a ring-like structure of dark matter, superimposed on a Hubble image of galaxy cluster Cl 0024+17." (Text in quotes is from the Hubble website). Go snowbots!
Below left, three candles against a backdrop of "bright, blue, newly formed stars blowing a cavity in the center of a star-forming region in the Small Magellanic Cloud."
Below right, an evergreen tree silhouettes Hubble's photo of the Sagittarius Star Cloud, "a narrow, dust-free region in the direction of the heart of the Milky Way, providing this spectacular glimpse of a treasure chest full of stars. Some of these gems are among the oldest inhabitants of our galaxy."
Our eyes are earthbound and sky-bourne: PanSTARRS at the University of Hawaii; Deep Impact (until it went dark August 8, 2013); the Spitzer Space Telescope; Messenger (our satellite orbiting Mercury); the STEREO twins, who have our back from both fore and aft; SOHO, the Solar Heliospheric Observatory, who just turned 18; the Very Large Telescope of ESO (European Southern Observatory) in Chile; the Fermi Gamma-Ray Space Telescope; the International Scientific Optical Network (ISON); and many more.
A daily eye-opener is the Astronomy Picture of the Day (APOD) <-- this link shows the 12/5/2013 pic. It's how our Sun will look in five billion years. Are you ready? Our old friend Voyager leads the way.
