Great new photos are in of the closest galaxy to our own Milky Way. The Andromeda galaxy lies 2 million light-years away from the Milky Way. Our neighbor is estimated to have nearly one trillion stars, compared to the hundreds of billions estimated stars that make up the Milky Way. The photos are from the Herschel Space Observatory.
The photos see longer-wavelength infrared light from the galaxy, which highlight the different colors of cool rings of dust.
The dust is said to be very cold and near absolute-zero in temperature. New stars are being born throughout the galaxy's rings.
The Herschel Observatory is a European Space Agency mission that NASA participates with.
