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/...
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...
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 ...
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...
galaxies : structureIf dwarf galaxies are primeval objects in the Universe, as hierarchical galaxy formation scenarios predict, they should show traces of their old stellar populations, perhaps distributed in extended, differentiated structures. The working hypothesis that such a structure could exist is...
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...

It is around 10 times fainter than most other known dwarf galaxies and is more than 10 times wider than it should be considering the number of stars it has. "With our present knowledge we do not understand how a galaxy with such extrem...
each star is a bit different from the next one and each star in the galaxy goes through a lifespan that makes a human's life look like a flash in the dark by comparison. Each one has a specific age, an evolutionary path that differs depending on its mass and other factors. One area...
