Scientists Triangulate Location of Dark Matter For First Time

An international team of astronomers led by Ohio State University has examined dark matter in the outer reaches of our galaxy in a new way.
For the first time, they were able to employ triangulation to estimate the location of dark matter and calculate its mass.

The results, reported May 30 at the meeting of the American Astronomical Society in Honolulu, suggest that this technique could help astronomers detect dark matter of a particular mass range for which there were previously no reliable tests.

To study dark matter, Gould and his team used triangulation a little differently. Over the summer of 2005, they watched a lensing event from two locations: Earth, and NASA's Spitzer Space Telescope, which is orbiting the sun some 25 million miles away.

This is pretty cool, as it expands our knowledge of Dark Matter and the Universe in general.

Hopefully this will help us learn even more about the enigma that is Dark Matter.
