How fast is the universe expanding?
The Universe is expanding, but how quickly is it expanding? How far away is everything getting from everything else? And how do we know any of this anyway?
Dark Energy Camera unveils small objects in solar system
The 570-megapixel Dark Energy Camera, built at DOE's Fermilab and mounted on the 4-meter Victor Blanco Telescope in Chile, delivers some of the most detailed images of celestial objects. While about a third ...
No Big Bang? Quantum equation predicts universe has no beginning
Planck mission explores the history of the universe
Hot gas, dust and magnetic fields mingle in a colorful swirl in this new map of our Milky Way galaxy. The image is part of a new and improved data set from Planck, a European Space Agency mission in which ...
Is the universe actually shrinking?
Whoa, here's something to think about. Maybe the Universe isn't expanding at all. Maybe everything is actually just shrinking, so it looks like it's expanding. Turns out, scientists have thought of this.
Bubbles from the galactic center: A key to understanding dark matter and our galaxy's past?
Compared to other galaxies, the Milky Way is a peaceful place. But it hasn't always been so sleepy. In 2010, a team of scientists working at the Harvard-Smithsonian Center for Astrophysics discovered a pair ...
Square Kilometre Array: Astronomers prepare to map the Universe with largest radio telescope ever built
An international team of scientists including Hans-Rainer Klöckner from the Max Planck Institute for Radio Astronomy in Bonn and Dominik Schwarz from the University of Bielefeld have joined forces to lay ...
Astronomers seek widest view ever of the universe with new telescope
At the annual meeting of the American Astronomical Society last week, the booth devoted to a revolutionary new telescope called the LSST got a lot of traffic.
Video: What is the biggest thing in the universe?
Think big. Really big. Like, cosmic big. How big can things in the Universe get? Is a galaxy big? What about a supercluster? What is the biggest thing in the Universe?
Study finds possible alternative explanation for dark energy
(Phys.org)—Dark energy is an unknown form of energy that is proposed to drive the accelerated expansion of the universe. A new study by University of Georgia professor Edward Kipreos suggests that changes ...
Researchers use real data rather than theory to measure the cosmos
For the first time researchers have measured large distances in the Universe using data, rather than calculations related to general relativity.
Berkeley algorithms help researchers understand dark energy
Scientists believe that dark energy—the mysterious force that is accelerating cosmic expansion—makes up about 70 percent of the mass and energy of the universe. But because they don't know what it is, ...
Physicists suggest new way to detect dark matter
For years physicists have been looking for the universe's elusive dark matter, but so far no one has seen any trace of it. Maybe we are looking in the wrong place? Now physicists from University of Southern ...
Three CfA Researchers Share in $3 Million Breakthrough Prize
Harvard researchers Robert Kirshner, Christopher Stubbs, and Peter Challis have been named co-recipients of the $3 million Breakthrough Prize in Fundamental Physics for their role in the 1998 discovery of dark energy and ...
