Things are pretty stressful on Earth right now -- so look at the sky!

These galaxies are selected from a Hubble Space Telescope program to measure the expansion rate of the universe, called the Hubble constant. The value is calculated by comparing the galaxies' distances to the apparent rate of recession away from Earth (due to the relativistic effects of expanding space). By comparing the apparent brightnesses of the galaxies' red giant stars with nearby red giants, whose distances were measured with other methods, astronomers are able to determine how far away each of the host galaxies are. This is possible because red giants are reliable milepost markers because they all reach the same peak brightness in their late evolution. And, this can be used as a

Why bother about space in the first place? Well, here's why.

A patch of the sky captured by the Hubble Space Telescope shows thousands of galaxies stretched over billions of light years. Only 10 percent of galaxies are observable with telescopes, according to the Great Observatories Origins Deep Survey (GOODS).

Latest census finds ten times more galaxies in the Universe — that’s nearly two trillion

More mind-boggling than ever.

This illustration shows the three steps astronomers used to measure the universe's expansion rate to an unprecedented accuracy, reducing the total uncertainty to 2.4 percent. Astronomers made the measurements by streamlining and strengthening the construction of the cosmic distance ladder, which is used to measure accurate distances to galaxies near and far from Earth.
