However most of the events we have found are blue and are either still rising or decaying slowly, on a timescale of years; the few spectra we have show AGN at z ∼ 1. We argue that these transients are background AGN microlensed by stars in foreground galaxies by a factor 10–100....
and all these galaxies are moving away from one another. 我们可以看到在它之外还有多个星系,所有这些星系都在彼此远离。 So multiple galaxies… moving away from each other… led to the theory… 所以多个星系相互远离导致了理论… MALE STUDENT:The big bang theory? 学生:大爆炸理论? MALE PROFESSOR:...
However, this will not always be the case. Whilst most galaxies are moving away from us, the Andromeda galaxy is moving towards us, with an expected collision happening in approximately 4.5 billion years. Hence, you have nothing to worry about then....

Now astronomers looked 8,000 light-years into the cosmos with the Hubble Space Telescope. Orbiting 370 miles up, above city lights and the rippling atmosphere, Hubble has confirmed the existence of black holes, revealed a gallery of bizarre galaxies, and chronicled the catastrophic (灾难的) ...
What star is at the center of our solar system? What are the largest stars called? What is the smallest known star? What is the importance of a star cluster? What is the small Magellanic cloud? What are globular clusters? What is the redshift of the Virgo cluster of galaxies?
What is the redshift of the Virgo cluster of galaxies? How big is an elliptical galaxy? How many irregular galaxies are there? What color are the planets in our solar system? What color is Eris, the dwarf planet? What color is Arcturus?
it tells me that there are millions of galaxies and potentially billions of planets. According to the positions of the stars, I observe that Saturn is in Leo. According to the scientific measurement of time, I deduce ...
