This version of the DESI map shows a subset of 400,000 of the 35 million galaxies that will be in the final map. The Earth is at the center, with the furthest galaxies plotted at distances of 10 billion light-years. 'In our Milky Way, we have different families of stars that are born more or less at the same time and more or less with the same chemical composition and same characteristics,' Valenari explained, adding that reconstructing these families can help scientists understand when and how the Milky Way was formed. A slice through the 3D map of galaxies from the first few months of the DESI survey. This type of diagram compares the brightness of stars with their color as a way to examine populations of stars and their evolution. 'Basically, you see the whole Milky Way in motion around its axis in this one image,' he said.Īntonella Valenari, a Gaia scientist from the University of Padua in Italy, introduced a Hertzsprung-Russell diagram based on the new Gaia data. Stars lagging behind as they orbit the center of the Milky Way appear to be traveling away from us, and those speeding up appear to be traveling toward us.

The white color shows when, on average, the stars are not moving in the line of sight with respect to us. You can view this free map of the universe with virtual reality gear or 3D glasses, on planetarium-like dome screens, or on your regular computer or television screen for a standard view. The colors run from blue (stars moving at 50 km/s toward us) to red (stars moving 50 km/s away from us). This radial velocity image shows the movement of 7 billion stars. 'Over the lifetime of five years of Gaia, we will actually get 29 independent measurements of whole sky,' Günther Hasinger, the European Space Agency's (ESA) director of science, said at the ILA. Each star is measured 70 times on average. As it rotates in space, Gaia measures about 100,000 stars each minute and covers the whole sky in about two months. Explore space and get a little closer to our wonderful universe with this awesome astronomy app This interactive 3D map is excellent for teachers to use for. Unlike space telescopes such as Hubble that orbit the Earth, Gaia can scan the cosmos without Earth blocking a large chunk of its view.

The spacecraft is perched far beyond the moon's orbit, in the Lagrange-2, or L2, point, a gravitationally stable spot about 1 million miles (1.5 million kilometers) away from Earth. The $1 billion (750 million euros) Gaia spacecraft launched in 2013 for a five-year mission to map the night sky with unmatched accuracy. The European Space Agency released a new map of nearly 1.7 billion stars from the Gaia spacecraft, giving the best-ever view of the Milky Way and neighboring galaxies in color.
