Hubblecast 22: Hubble Space Telescope Directly Observes Exoplanet Orbiting Fomalhaut.

The NASA/ESA Hubble Space Telescope has discovered an extrasolar planet, for the first time using direct visible-light imaging. The strange world is far-flung from its parent star, is surrounded by a colossal belt of gas and dust, and may even have rings more impressive than Saturn’s.

Integral – Observing the violent and extremely variable universe.

A video by ESA regarding the Integral space telescope.

‘At the Science Data Centre of ESA’s Integral mission, in Versoix, Switzerland, scientists using the space observatory target and study known sources of gamma-rays.
But Integral is also designed to record serendipitous phenomena, or unexpected transient objects. The observatory plays the role of a sentinel alerting the worldwide scientific community about new and unusual high-energy events in the universe. When such events occur, data is sent to its owner before the scientific community is alerted. So that other observatories and Telescopes also have the chance to observe the object in question.

Gamma-rays come from all around the universe, and when collecting data, Integral must filter point sources from background noise. For Integral, the level of noise in the gamma-ray environment is quite high. Poland’s Centre for Space Research helped develop the observatory’s noise reduction system — one of the satellite’s most important subsystems.’
