Milky Way explosion detected by Hubble telescope
The Hubble observatory has found evidence of a cataclysmic flare that punched its way out of our galaxy about 3.5 million years ago. Australian scientists used the space telescope to detect the imprint of the ancient explosion in a trail of gas some 200,000 light-years from the heart of the Milky Way.
