... 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. ...

When constructing the visits of your Phase 2 program, please consider the guidelines and rules given in the HST Primer, Section 6.2., to determine when to create new visits. ... Because the SAA reduces the full orbital visibility period of many targets for over half of the HST orbits each day (see Section 2.2.2 of the HST Primer), visits that require more than 5 consecutive orbits are less likely to have scheduling opportunities on most days of the HST observing cycle. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

Cosmic rays are not the only sign of high energy particles in the distant universe. Additional evidence comes (like most astronomical data) from visible light and other types of electromagnetic waves , e.g. x-rays and radio waves. ... Photons of visible light have about 2 electron volts (ev), while medical x-ray photons may have energies of 50,000 ev and those of gamma rays reach 1,000,000 ev and even more. ... To produce x-rays or gamma rays, electrons must collide with something. ...
