Astronomers Solve Cold Cosmic Mystery

April 20, 2015 7:00 am | by Univ. of Hawaii at Manoa | News | Comments

In 2004, astronomers examining a map of the radiation leftover from the Big Bang discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in the infant universe, but a spot this large and this cold was unexpected. Now, a team may have found an explanation for its existence.

Dark Matter Might Not Be

April 15, 2015 7:00 am | by Durham Univ. | News | Comments

Astronomers believe they might have observed the first potential signs of dark matter interacting with a force other than gravity. They saw a dark matter clump that appeared to be lagging behind the galaxy it surrounds. Such an offset is predicted during collisions if dark matter interacts, even very slightly, with forces other than gravity.

‘Fingerprint’ Sheds Light on Moon’s Explosive Past

April 9, 2015 7:00 am | by Univ. of Maryland | News | Comments

Within the first 150 million years after our solar system formed, a giant body struck and merged with Earth, blasting a cloud of debris into space. This cloud eventually formed the moon. Or so we thought, the expectation has long been that the moon should carry the isotopic "fingerprint" of the foreign body. But, new research shows its fingerprint is very close to Earth’s.

Sun Has Seasons

April 8, 2015 7:00 am | by National Center for Atmospheric Research | News | Comments

The Sun undergoes a type of seasonal variability, with its activity waxing and waning over the course of nearly two years, according to a new study by a team of researchers. This behavior affects the peaks and valleys in the approximately 11-year solar cycle, sometimes amplifying and sometimes weakening the solar storms that can buffet Earth’s atmosphere.

A number of spaceflight endurance records will be broken during the mission.

Telescopes Explain Mysterious 17th Century Explosion

March 24, 2015 7:00 am | by ESO | News | Comments

New observations made with telescopes reveal that the star that European astronomers saw appear in the sky in 1670 was not a nova, but a much rarer, violent breed of stellar collision. It was spectacular enough to be easily seen with the naked eye during its first outburst, but the traces it left were so faint that very careful analysis using submillimeter telescopes was needed before the mystery could be explained.

Jupiter's Journey Shaped Our Strange Solar System
