Relativity passes test on a galactic scale
Gravity behaves the same way on a galactic scale as it does in our solar system, and alternative gravity models which remove the need for dark energy are disfavoured.

Hubble expansion discrepancy deepens
In the 1920s, Edwin Hubble discovered that the universe is expanding by showing that more distant galaxies recede faster from Earth than nearby ones. Hubble’s measurements of the expansion rate, now...

Spotting the first extragalactic planets
Three decades since astronomers first detected planets outside our solar system, exoplanets are now being discovered at a rate of hundreds per year. Although it is reasonable to assume other galaxies ...
