Hubble's New Camera Delivers Breathtaking Views of the Universe

An Early Release Observation Release

April 30, 2002: Jubilant astronomers unveiled humankind's most spectacular views of the universe, courtesy of the newly installed Advanced Camera for Surveys (ACS) aboard NASA's Hubble Space Telescope. Among the suite of four ACS photographs to demonstrate the camera's capabilities is a stunning view of a colliding galaxy dubbed the "Tadpole" (UGC10214). Set against a rich tapestry of 6,000 galaxies, the Tadpole, with its long tail of stars, looks like a runaway pinwheel firework. Another picture depicts a spectacular collision between two spiral galaxies -- dubbed "The Mice" -- that presages what may happen to our own Milky Way several billion years from now when it collides with the neighboring galaxy in the constellation Andromeda. Looking closer to home, ACS imaged the "Cone Nebula," a craggy-looking mountaintop of cold gas and dust that is a cousin to Hubble's iconic "pillars of creation" in the Eagle Nebula, photographed in 1995. Peering into a celestial maternity ward called the Omega Nebula or M17, ACS revealed a watercolor fantasy-world of glowing gases, where stars and perhaps embryonic planetary systems are forming.

Q & A: Understanding the Discovery

  1. 1. How will ACS make the Hubble telescope a better orbiting observatory?


  2. ACS can cover twice the area in less time than Hubble's "workhorse" camera, the Wide Field and Planetary Camera 2 (WFPC2). The camera delivers a panoramic crispness comparable to that of a wide-screen IMAX movie. The camera's tenfold increase in efficiency will open up much anticipated new "discovery space" for Hubble. ACS will allow astronomers to push back the frontier of the early universe. Astronomers believe that ACS will be able to peer into the "twilight zone" period, when galaxies were just beginning to form out of the blackness following the cooling of the universe from the big bang, the cataclysmic explosion that created the cosmos.
