A New Galactic Yardstick
« on: April 02, 2014, 04:26:43 PM »

Astronomers have developed a new method to measure distances to bright but faraway galaxies, a tool which will help better constrain the expansion rate of the universe.

The nature of the universe lies within a single constant. Measuring this one number — known as the Hubble constant — tells us the universe’s expansion rate, its age, and ultimately, its fate. Now a team of astronomers led by Yuzuru Yoshii (University of Tokyo) has developed an entirely new method to measure this crucial number.
