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 ...
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 which form first.Why does the writer write the ...
How old is our galaxy? Most galaxies arebetween 10 billion and 13.6 billion years old. Our universe is about 13.8 billion years old, so most galaxies formed when the universe was quite young! Astronomers believe that our own Milky Way galaxy is approximately 13.6 billion years old. Who calcul...
After all, this fantastic physical process takes hundreds of millions of years to play out, so the few short decades that we've been observing them simply isn't enough time to watch the drama unfold in real time. For quite a while, astronomers didn't know if galaxies were actively merging...
. He4that nebulae were galaxies themselves, and thus, astronomers now5to the view that distant galaxies do exist. He then made more observations of forty-six galaxies that were travelling away from Earth with speeds that were6directly to the galaxies distance from Earth. Hubble discovered the ...
It was a big moment for our cosmos when the first stars awoke, but it's an elusive one for scientists. In new research, however, a team of astronomers has identified some of the oldest galaxies ever seen. These objects were already fully formed when the universe was just 680 million year...
Already, this looks like a huge mistake: the new space telescope has produced embarrassing images of ancient galaxies that shouldn’t exist. We won’t dig into the Big Bang question here mostly because things are changing so fast almost anything I think to type will be obsolete before it ...
Stars form within clouds of dust and gas known as the interstellar medium within galaxies. This interstellar medium is mostly made up of hydrogen and some carbon and silicates. The temperature of this medium is also very cold causing the ingredients to bind and clump together. The result is ...
We also might learn about other aspects of physics. So I’m interested in some of these big radio telescope arrays, because they might be able to tell us something about dark matter, if dark matter is annihilating in the distant universe. That can change how first stars and galaxies are ...
Explain why astronomers of today can actually observe galaxies as they were billions of years ago. Why do the most luminous stars end their lives on the main sequence the quickest? Why do so few visual binary star systems been full...
