A hundred years ago, astronomer Edwin Hubble dramatically expanded the size of the known universe. At a meeting of the American Astronomical Society in January 1925, a paper read by one of his colleagues on his behalf reported ...
In the years following the launch of NASA's Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby stellar island to our Milky ...
For humans, the most important star in the universe is our sun. The second-most important star is nestled inside the Andromeda galaxy. Don't go looking for it—the flickering star is 2.2 million light-years away, and is 1/100,000th ...
Researchers have finished equipping the Subaru Telescope with a new special "compound eye," culminating several years of effort. This new eye is an instrument featuring approximately 2,400 prisms scattered across the extremely ...
A group of astronomers have made history by capturing an image of a record number of stars from a time when the universe was half its age.
Looking halfway across the observable universe and expecting to see individual stars is considered a non-starter in astronomy, a bit like raising a pair of binoculars at the moon in hopes of making out individual grains of ...
Astronomers have known for a century that the universe is expanding. We can now trace this expansion over much of its almost 14 billion year history, with important constraints going back to just one second after the Big ...
On Sunday November 23, 1924, 100 years ago this month, readers perusing page six of the New York Times would have found an intriguing article, amid several large adverts for fur coats. The headline read: Finds Spiral Nebulae ...
Massive stars about eight times more massive than the sun explode as supernovae at the end of their lives. The explosions, which leave behind a black hole or a neutron star, are so energetic they can outshine their host galaxies ...
Using the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Chinese astronomers have identified nearly 300 candidate supergiant stars in the Andromeda and Triangulum galaxies. The finding was reported in ...
