New Data Suggests We Don’t Live in a Void, and Supports Dark Energy
Hubble extends stellar tape measure 10 times farther into space
(Phys.org) —Using NASA's Hubble Space Telescope, astronomers now can precisely measure the distance of stars up to 10,000 light-years away—10 times farther than previously possible.
Baryon Oscillation Spectroscopic Survey measures the universe to one-percent accuracy
Today the Baryon Oscillation Spectroscopic Survey (BOSS) Collaboration announced that BOSS has measured the scale of the universe to an accuracy of one percent. This and future measures at this precision ...
Physicists propose Higgs boson 'portal' as the source of this elusive entity
One of the biggest mysteries in contemporary particle physics and cosmology is why dark energy, which is observed to dominate energy density of the universe, has a remarkably small (but not zero) value. This value is so small, ...
Hubble telescope breaks record for farthest supernova
(Phys.org) —The supernova, designated SN UDS10Wil, belongs to a special class of exploding stars known as Type Ia supernovae. These bright beacons are prized by astronomers because they can be used as a ...
