ESA Releases Gaia’s Billion-Star Map of Milky Way Galaxy

Sep 15, 2016 by News Staff

On its way to assembling the most detailed 3D map ever made of our Galaxy, ESA’s Gaia spacecraft has pinned down the precise position on the sky and the brightness of 1.142 billion stars, and in addition measured the velocity and distance of two million of them relative to the Sun. An all-sky view of stars in the Milky Way and neighboring galaxies, based on the first year of observations from ESA’s Gaia satellite, from July 2014 to September 2015....

The first detection of Pluto in X-rays has been made using NASA’s Chandra X-ray Observatory. The main panel in this graphic is an optical image taken from New Horizons on its approach to Pluto, while the inset shows an image of Pluto in X-rays from Chandra. There is a significant difference in scale between the optical and X-ray images. New Horizons made a close flyby of Pluto but Chandra is located near the Earth, so the level of detail visible in the two images is very different. The Chandra image is 180,000 miles across at the distance of Pluto, but the planet is only 1,500 miles across. Pluto is detected in the X-ray image as a point source, showing the sharpest level of detail available for Chandra or any other X-ray observatory. This means that details over scales that are smaller than the X-ray source cannot be seen here. Image credit: X-ray – NASA / CXC / JHUAPL / R.McNutt et al; optical – NASA / JHUAPL.

Colors distinguish different linguistic macroareas, regions with relatively little or no contact between them (but with much internal contact between their populations). These are North America (orange), South America (dark green), Eurasia (blue), Africa (green), Papua New Guinea and the Pacific Islands (red), and Australia (fuchsia). Image credit: Damián E.
