1st fast radio burst traced to old, dead, elliptical galaxy
Astronomers thought they understood fast radio bursts: A recent one calls that into question
Fast radio bursts are mysterious and brief flashes of radio emissions that were thought to be produced by magnetars, highly magnetized rotating neutron stars. Yet magnetars appear primarily in young star clusters.
New research suggests that a massive, unidentified object might have passed through our Solar System billions of years ago, ...
Hubble Space Telescope images of Jupiter have been "photo-mapped onto a sphere," and animated into a full rotation, according to ESA/NASA. Credit: Space.com | NASA, ESA, J. DePasquale (STScI), A. Simo ...
Included in the image are (from top to bottom) Jupiter, Saturn ... It is also called the “Cigar Galaxy” because of the elliptical shape produced by the oblique tilt of its starry disk relative ...
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 ...
Our galaxy, while not small, isn't nearly as big as Andromeda. We harbor some 100 to 400 billion stars. One day, however, the two galaxies may collide, forming a giant, egg-shaped elliptical ...
This rare quasar with spiral arms could help astronomers understand how supermassive black holes feed and grow.
"Andromeda looks like a transitional type of galaxy that's between a star-forming spiral and a sort of elliptical galaxy dominated by aging red stars," said Weisz. "We can tell it's got this big ...
