... October 4, 1997 . In the Center of 30 Doradus . Credit: WFPC2 , Hubble Space Telescope , NASA . Explanation: In the center of 30 Doradus lies a huge cluster of the largest, hottest, most massive stars known. The center of this cluster, known as R136 , is boxed in the upper right portion of the above picture. ... Although the ages of stars in R136 cause it to be best described as an open cluster , R136's density will likely make it a low mass globular cluster in a few billion years. ...

... October 8, 1996 . ROSAT Explores the X-Ray Sky . ... Explanation: Launched in 1990, the orbiting ROSAT observatory explored the Universe by viewing the entire sky in x-rays - photons with about 1,000 times more energy than visible light . This ROSAT survey produced the sharpest, most sensitive image of the x-ray sky to date. The all-sky image is shown with the plane of our Milky Way Galaxy running horizontally through the center. ...
