The article Astronomers Crunch Numbers, Universe Gets Bigger said

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.
 
That means that the universe could be 15 percent bigger and 15 percent older than any previous calculations suggested.
 
The astronomers came to this conclusion after they invented a new method for calculating intergalactic distances, one that is more precise and much simpler than standard methods. Kris Stanek, associate professor of astronomy at Ohio State, and his coauthors describe the method in a paper to appear in the Astrophysical Journal.

Dr. Krzysztof “Kris” Stanek is associate professor at the Department of Astronomy of The Ohio State University. His previous position was at the faculty in the Department of Astronomy of the Harvard University. And before Harvard, he was a Research Assistant at the Department of Astrophysical Sciences, Princeton University.
