The largest digital camera ever built for a space mission has been painstakingly mosaicked together from 106 separate electronic detectors. The resulting “billion-pixel array†will serve as the super-sensitive ‘eye’ of ESA’s Galaxy-mapping Gaia mission.

A total of 106 CCDs make up Gaia’s focal plane. Technicians from Astrium France, the Gaia mission’s prime contractor, are seen bolting and aligning the …
NASA’s Hubble Space Telescope crossed another milestone in its space odyssey of exploration and discovery. On Monday, July 4, 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 … Read the rest of this article
Galaxies once thought of as voracious tigers are more like grazing cows, according to a new study using NASA’s Spitzer Space Telescope.
Astronomers have discovered that galaxies in the distant, early universe continuously ingested their star-making fuel over long periods of time. This goes against previous theories that the galaxies devoured their fuel in quick bursts after run-ins with other … Read the rest of this article
Mirrors are a critical part of a telescope. The quality is crucial, so completion of mirror polishing represents a major milestone. All of the mirrors that will fly aboard NASA’s James Webb Space Telescope have been polished so the observatory can see objects as far away as the first galaxies in the universe.

Astronomers have pushed NASA’s Hubble Space Telescope to its limits by finding what is likely to be the most distant object ever seen in the universe. The object’s light traveled 13.2 billion years to reach Hubble, roughly 150 million years longer than the previous record holder. The age of the universe is approximately 13.7 billion years.
