... 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. ...

... STScI-PRC99-27 A CLOSER ENCOUNTER WITH MARS Taking advantage of Mars's closest approach to Earth in eight years, astronomers using NASA's Hubble Space Telescope have taken the space-based observatory's sharpest views yet of the Red Planet. ... In these views the north polar cap is tilted toward the Earth and is visible prominently at the top of each picture. ... Dark sand dunes that surround the polar cap merge into a large, dark region called Acidalia. ...

HST?s on-board software then computes a correction for the parallax induced by the telescope?s orbit. ... However, HST?s on-board parallax correction may be insufficient for a target closer than 3.8 million kilometers. ... An HST-centric target ephemeris is generated. ... An HST-centric ephemeris should be specified only for very close targets such as the Moon. ...

... Planets . ... Earth Satellites . ... Looking in the direction of the constellation Cygnus the Swan and launched by NASA in 2009 is the Kepler Space Observatory.Many previous missions searching for exoplanets mainly detected large giant planets, like large hot Jupiters (it is easier to detect larger planets).However KeplerтАЩs main objective is to search for much smaller planets located in a habitable zone which is not too close nor too far from their star; planets which may be just like our Earth. ...

... Figure 8: Can you detect the motion of the near-Earth asteroid 2000PH against the background stars during its close approach to Earth around 27 July 2004? ... Down) observed and imaged the unusual near-Earth asteroid 2000PH during its close approach to the Earth around 27 July 2004. The observations were carried out remotely using the new 2m aperture Faulkes telescope situated on the 10,000-foot summit of Haleakala, on the island of Maui in Hawaii. ...

. The NEAR Shoemaker spacecraft took this image of the surface of Eros as it made its closest approach to the large asteroid.
