VLA Reveals New Object Near Supermassive Black Hole in Famous Galaxy
VLA New Object Near Supermassive Black Hole Galaxy
2017/7/20
Pointing the National Science Foundation’s Very Large Array (VLA) at a famous galaxy for the first time in two decades, a team of astronomers got a big surprise, finding that a bright new object had a...
Astronomers observe early stages of Milky Way-like galaxies in distant universe
Astronomers early stages Milky Way-like galaxies distant universe

For decades, astronomers have found distant galaxies by detecting the characteristic way their gas absorbs light from a bright quasar in the background. But efforts to observe the light emitted by the...
New delta Scuti:Rare pulsating star 7,000 light years away is 1 of only 7 in Milky Way
New delta Scuti pulsating star 7,000 light years 1 of only 7 Milky Way
2017/3/13
The star is one that pulsates and so is characterized by varying brightness over time. It’s situated 7,000 light years away from the Earth in the constellation Pegasus, said astronomer Farley Fer...
