Chandra Confirms the Hubble Constant

A critically important number that specifies the expansion rate of the Universe, the so-called Hubble constant, has been independently determined using NASA’s Chandra X-ray Observatory. This new value matches recent measurements using other methods and extends their validity to greater distances, thus allowing astronomers to probe earlier epochs in the evolution of the Universe.

The Universe Could Be Larger Than Previously Thought

That intergalactic road trip to Triangulum is going to take a little longer than you had planned.

An Ohio State University astronomer and his colleagues have determined that the Triangulum Galaxy, otherwise known as M33, is actually about 15 percent farther away from our galaxy than previously measured.

This finding implies that the Hubble constant, a number that astronomers rely on to calculate a host of factors — including the size and age of the universe — could be significantly off the mark as well.
