Light is shifted towards the long wavelength, red end of the spectrum. This tells us that: other galaxies are moving away from our galaxy; the Universe is expanding. Astronomers have found that ...

A tiny red speck has set a date on an important era in the Universe's early history and given astronomers a surprising ...

Hubble's brilliant observation was that the red shift of galaxies was directly proportional to the distance of the galaxy from earth. That meant that things farther away from Earth were moving ...

Astronomers discovered bright hydrogen emissions from an ancient galaxy, puzzling researchers over how this light pierced the universe's early hydrogen fog.
