Hubble Telescope makes over one million observations

This is an artist’s concept of that planet, HAT-P-7b. It is a “hot Jupiter” class planet orbiting a star that is much hotter than our sun. Hubble Space Telescope’smillionth science observation was trained on this planet to look for the presence of water vapor and to study the planet’s atmospheric structure via spectroscopy.

Last Summer Hubble took it’s one Millionth Observation

Source NASA -NASA’s Hubble Space Telescope crossed another milestone in its space odyssey of exploration and discovery. On Monday, July 4 2011, the Earth-orbiting observatory logged its one millionth science observation during a search for water in an exoplanet’s atmosphere 1,000 light-years away.

“For 21 years Hubble has been the premier space science observatory, astounding us with deeply beautiful imagery and enabling ground-breaking science across a wide spectrum of astronomical disciplines,” said NASA Administrator Charles Bolden. He piloted the space shuttle mission that carried Hubble to orbit. “The fact that Hubble met this milestone while studying a faraway planet is a remarkable reminder of its strength and legacy.”

Although Hubble is best known for its stunning imagery of the cosmos, the millionth observation is a spectroscopic measurement, where light is divided into its component colors. These color patterns can reveal the chemical composition of cosmic sources.

Hubble’s millionth exposure is of the planet HAT-P-7b, a gas giant planet larger than Jupiter orbiting a star hotter than our sun. HAT-P-7b, also known as Kepler 2b, has been studied by NASA’s planet-hunting Kepler observatory after it was discovered by ground-based observations. Hubble now is being used to analyze the chemical composition of the planet’s atmosphere.
