Dark Energy Survey Reveals Rare Superluminous Supernova

The Dark Energy Survey has revealed a rare, ‘superluminous’ supernova that erupted in a galaxy 7.8 billion light years away. The first images taken by the Dark Energy Survey (DES) after the survey began in August 2013 have revealed a rare, ‘superluminous’ supernova that erupted in a galaxy 7.8 billion light years away. The stellar […]

Fermi Discovers New Clues To Dark Matter

New maps from the Fermi-LAT Collaboration show that the galactic center produces more high-energy gamma rays than can be explained by known sources, suggesting that this excess emission is consistent with some forms of dark matter. A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that […]

New Research Suggests Dark Energy Hides Behind Phantom Fields

New theoretical research suggests that quintessence and phantom fields, two of the many theories that try to explain the nature of dark energy, are only a mirage in the observations and it is the quantum vacuum which could be behind the energy that moves our universe. Cosmologists believe that some three quarters of the universe […]

Xrays from Other Galaxies Could Emanate from Dark Matter

Two new studies report that x-rays emanating from the hearts of nearby galaxies and galaxy clusters could be signs of particles of dark matter decaying in space. X-rays of a specific wavelength emanating from the hearts of nearby galaxies and galaxy clusters could be signs of particles of dark matter decaying in space, two independent […]

Researchers Shed New Light on Dark Energy

Dartmouth researchers shed new light on dark energy and eliminate the possibility that our planet, solar system and galaxy are at the center of the universe. In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion. While the findings don’t explain the cosmic speed-up, […]

Dark Energy Survey Mission Begins

After 10 years of planning, building and testing, the Dark Energy Survey (DES) has officially begun. Tonight, as the sun sinks below the horizon, the world’s most powerful digital camera will once again turn its gleaming eye skyward. Tonight, and for hundreds of nights over the next five years, a team of physicists and astronomers […]

Scientists Propose Higgs Boson Portal to Help Explain Dark Energy

A newly published study explores how the recently discovered Higgs boson may provide a possible “portal” to physics that will help explain some of the attributes of dark energy. 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 […]

Physicists have been able to create an atomic gas that can attain a temperature below absolute zero, -273.15˚C. They were able to create this gas using negative-Kelvin materials and new quantum devices. The scientists published their findings in the journal Science¹. The absolute temperature scale dates back to Lord Kelvin, who created it in the […]

Scientists Use Quasars to Probe Dark Energy & Measure its Role in the Eevolution of the Universe

An international team of scientists are measuring the role of dark energy in the evolution of the universe by using a new mapping technique that uses quasars to probe dark energy over 10 billion years in the past. BOSS, the Baryon Oscillation Spectroscopic Survey, is mapping a huge volume of space to measure the role […]
