This is long enough for other planets to have intelligen life. The second reason is size. The universe is huge. Take the Hubble Telescope( 哈勃望远镜):it has shown that there are at least 100 billion galaxies( 星系). And our planet, the Milky Way, has at least 100 billion stars. Some...
Do Unusually Cold Starburst Galaxies Exist? A Case Studydoi:10.3847/1538-4357/ada4acWe report observations of CO(J = 9 → 8) and OH+(N = 1 → 0) toward the four millimeter-selected lensed starburst galaxies SPT 235458, 015059, 031444, and 045250, using the Atacama Large Millimeter/...
Several optical images from the SuperCOSMOS sky survey, were seen at the Siding Spring Observatory in Coonabarabran in western New South Wales. It was discovered that no isolated dark galaxies exist in the southern sky outside the ...
Our universe is unimaginably big. Hundreds of billions, if not trillions, ofgalaxiesspin through space, each containing billions or trillions ofstars. Some researchers studying models of the universe speculate that the universe's diameter could be 7 billionlight-yearsacross. Others think it could ...
In view of these and other HST results for metal-poor galaxies it seems that the local Universe simply may not contain any galaxies that are currently undergoing their first burst of star formation. 展开 关键词: Galaxies: Dwarf Galaxies: Evolution Galaxies: Individual: Alphanumeric: SBS 1415+...
Not to be confused with the age of very distant galaxies as observed today by our telescopes which is actually observing these distant galaxies as they were many billions of years ago in the early formation but instead I am asking about their absolute age today assuming they still exist? I ...
The galaxy is the system that is bounded with gravitation and consists of stars, planets and other matters. The galaxies can be large or small depends on the space covered by them in the universe.Answer and Explanation: The distribution of galaxies in the universe is not arbitrary, they are...
All galaxies are believed to be wrapped in an invisible halo of dark matter, and this envelope is vitally important; galaxies are rotating so rapidly, that without dark matter, they would have been torn apart long ago if they were held together only by the influence of their stars, gas, ...
As Tony Flanders suggests, they are ancient and maybe have been existing from the earliest times. Yes, they have talked about blue stragglers forming from white dwarfs swallowing other stars. Also, certainly many of them are cores of other galaxies gobbled up by bigger galaxies, such as the...
