The images below show how galaxies similar in mass to our home galaxy, the Milky Way, evolved over time. The images taken by the NASA/ESA Hubble Space Telescope reveal that Milky Way-like galaxies grow larger in size and in stellar mass … Continue reading
In one of the most comprehensive multi-observatory galaxy surveys yet, astronomers find that galaxies like our Milky Way underwent a stellar “baby boom,” churning out stars at a prodigious rate, about 30 times faster than today. Our Sun, however, is … Continue reading
In analyzing data from deep-sky census assembled from surveys taken by NASA’s Hubble Space Telescope and other observatories, a team led by Christopher Conselice of the University of Nottingham, U.K., found that 10 times as many galaxies were packed into … Continue reading
The Orion Arm is a minor spiral arm of the Milky Way some 3,500 light-years (1,100 parsecs) across and approximately 10,000 light-years (3,100 parsecs) in length. The Solar System, including the Earth, lies within the Orion Arm. It is also … Continue reading
