The Largest Digital Sky Survey Has Been Released By Astronomers

This compressed view of the entire sky visible from Hawai’i by the Pan-STARRS1 Observatory is the result of half a million exposures, each about 45 seconds in length, taken over a period of 4 years. The shape comes from making a map of the celestial sphere, like a map of the Earth, but leaving out the southern quarter. The disk of the Milky Way looks like a yellow arc, and the dust lanes show up as reddish brown filaments. The background is made up of billions of faint stars and galaxies. If printed at full resolution, the image would be 1.5 miles long, and you would have to get close and squint to see the detail.

SCiTechDaily: Astronomers Release the Largest Digital Sky Survey

The Pan-STARRS project is publicly releasing the world’s largest digital sky survey from the Space Telescope Science Institute (STScI).

“The Pan-STARRS1 Surveys allow anyone to access millions of images and use the database and catalogs containing precision measurements of billions of stars and galaxies,” said Dr. Ken Chambers, Director of the Pan-STARRS Observatories. “Pan-STARRS has made discoveries from Near Earth Objects and Kuiper Belt Objects in the solar system to lonely planets between the stars; it has mapped the dust in three dimensions in our galaxy and found new streams of stars; and it has found new kinds of exploding stars and distant quasars in the early universe.”

“With this release we anticipate that scientists – as well as students and even casual users – around the world will make many new discoveries about the universe from the wealth of data collected by Pan-STARRS,” Chambers added.
