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 ...
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+...
to 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 were(5) directly to the galaxies' distance from Earth.Hubble discovered the scientific rule now called. "Hubble's Law"-- that ...
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 ...

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...
This is long enough for other planets to have intelligent life. The second reason is size. The universe is huge. ‘Tools like the Hubble Telescope (哈勃望远镜) have shown that there are at least 100 billion galaxies (星系). And our galaxy, the Milky Way (银河系), has at least 100 ...
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...
First of all,our planet is only a tiny point in the whole universe,so there may have other lives beyond the Earth.According to the astronomers’ estimation,there are over 100 billion other galaxies.This proves that the universe is immense.No one can deny the fact that other lives exist,...
