Sky survey reveals newborn jets in distant galaxies（图）
Sky survey newborn jets distant galaxies
2020/12/11
Astronomers using data from the ongoing VLA Sky Survey have found distant galaxies with supermassive black holes at their cores that have launched powerful, radio-emitting jets of material w...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have revealed an extremely distant and therefore very young galaxy that looks surprisingly like our Milky Way. The results are...
ALMA spots most distant dusty galaxy hidden in plain sight（图）
ALMA spots distant dusty galaxy hidden plain sight
2019/12/13
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have spotted the light of a massive galaxy seen only 970 million years after the Big Bang. Called MAMBO-9, it's the most dista...
Astronomers find a golden glow from a distant stellar collision（图）
Astronomers golden glow distant stellar collision
2019/11/15
An NSF-supported team of astronomers found new evidence of the occurrence of a kilonova -- a cosmic explosion that creates massive amounts of gold and platinum -- that went unnoticed during initial ob...
With the help of a gigantic cosmic lens, astronomers have measured the magnetic field of a galaxy nearly five billion light-years away. The achievement is giving them important new clues about a probl...

We present a proper motion measurement for the halo globular cluster Pyxis, using HST/ACS data as the first epoch, and GeMS/GSAOI Adaptive Optics data as the second, separated by a baseline of ～ 5 yea...
ALMA investigates ‘DeeDee,’a distant,dim member of our solar system
ALMA DeeDee a distant dim member solar system
2017/4/27
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have revealed extraordinary details about a recently discovered far-flung member of our solar system, the planetary body 2014...
Mysterious cosmic explosion surprises astronomers studying the distant x-ray universe
cosmic explosion astronomers distant x-ray universe
2017/4/27
A mysterious flash of X-rays has been discovered by NASA’s Chandra X-ray Observatory in the deepest X-ray image ever obtained. This source likely comes from some sort of destructive event, but it may ...
Astronomers observe early stages of Milky Way-like galaxies in distant universe
Astronomers early stages Milky Way-like galaxies distant universe
2017/3/30
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...

Pushing the limits of the largest single-aperture millimeter telescope in the world, and coupling it with gravitational lensing, University of Massachusetts Amherst astronomer Alexandra Pope and colle...
UCLA astronomers make first accurate measurement of oxygen in distant galaxy
UCLA astronomers first accurate measurement of oxygen galaxy
2016/8/11
UCLA astronomers have made the first accurate measurement of the abundance of oxygen in a distant galaxy. Oxygen, the third-most abundant chemical element in the universe, is created inside stars and ...

ALMA Weighs Supermassive Black Hole Distant Spiral Galaxy
2015/7/13
Supermassive black holes lurk at the center of every large galaxy. These cosmic behemoths can be millions to billions of times more massive than the Sun. Determining just how massive, however, has bee...
