Astronomers know, however, that the distant Universe should be brimming with pairs of supermassive black holes embedded within merging galaxies. The first hints of such a system were found in data from theNASA/ESAHubble Space Telescope, which revealed two closely aligned pinpoints of light in the ...
Supermassive black holes are much bigger — they can be billions of times the mass of our sun.Scientists believe supermassive black holes may be connected to the formation of galaxies, as they often exist at the center of the mass star stems but it is still not clear exactly how, or ...
watching the interplay of two galaxies as they mixed and mingled via gravity. And he saw an interesting feature: An "arm" of stars reached out between the galaxies as they drew near, with a "counterarm" appearing on the opposite side of each galaxy. While the results were intriguing, he ...
Oldest meteorite ever found: 4.6 BILLION-year-old space rock discovered in the Sahara could shed light on the early solar system. An ancient, meteorite, orachondrite, was discovered in the Sahara desert last year that has now been identified as chunk from a protoplanet that formed before Earth...
That isn't surprising — we've found galaxies that old before — but in this study, the researchers added a new wrinkle: By examining the radiation emanating from the environment near the trio, they discovered that the galaxies had already begun to blow bubbles of ionized plasma into their ...
supply supports an abundance of life far greater than that usually found in the deep-sea. I have spent the past three years trying to fathom the lives of these animals, but their remote habitat has not made this easy. Although described as eyeles...
from Earth with speeds that were6directly to the galaxies distance from Earth. Hubble discovered the scientific rule — now called “Hubble’s Law” — that the farther away a galaxy is, the greater its speed. As one of the most important7, he devoted himself to galaxies, which led to ...
I can add another data point. I've compared the full set of Nikon NAV-SW eyepieces to a selection of Delos and Pentax XWs (I have most of them). My testing was done before I discovered this thread. My targets were primarily double stars and star fields. I was using m...
This computer-simulated image shows a supermassive black hole, weighing 17 billion suns, discovered in a sparsely populated area of the universe with the NASA’s Hubble Space Telescope and the Gemini Telescope in Hawaii. Black holes were previously believed to be located in very large galaxies in...
If some unknown cause of red shift - such as light becoming "tired" from traveling long distances through empty space - is discovered, what effect would there be on cosmology? A galaxy merger happens when two galaxies collide with ...
