All through history, humans have created and shared stories that ponder the creation of stars — what they are and how the first stars came to be. Now, with new results from the Hydrogen Epoch of Reion...
Cosmic Magnifying Lens Reveals Inner Jets of Black Holes（图）
Cosmic Magnifying Lens Inner Jets Black Holes
2017/9/5
"We have known about the existence of these clumps of material streaming along black hole jets, and that they move close to the speed of light, but not much is known about their internal structure or ...
Astronomers have found an enormous, glowing blob of gas in the distant universe, with no obvious source of power for the light it is emitting. Called an "enormous Lyman-alpha nebula" (ELAN), it is the...
Astrophysicists from Johns Hopkins University have proposed a clever new way of shedding light on the mysterious dark matter believed to make up most of the universe. The irony is they want to try to ...

cosmic stickiness favors Big Rip demise of universe
2015/7/13
The universe can be a very sticky place, but just how sticky is a matter of debate.That is because for decades cosmologists have had trouble reconciling the classic notion of viscosity based on the la...

The intergalactic medium unveiled Caltech's Cosmic Web Imager
2014/5/13
Caltech astronomers have taken unprecedented images of the intergalactic medium (IGM)—the diffuse gas that connects galaxies throughout the universe—with the Cosmic Web Imager, an instrument designed ...
Astronomers have discovered a distant quasar illuminating a vast nebula of diffuse gas, revealing for the first time part of the network of filaments thought to connect galaxies in a cosmic web. Resea...
