Astronomers spy most distant galaxy cluster ever observed. A young galaxy cluster 11.1 billion light-years from Earth is the most distant ever observed, astronomers say. Multiple space telescopes were used to spot CL J1001+0220, where nine of its 11 […]

Faraway galaxy made mostly of dark matter . A Milky Way-sized galaxy made up almost entirely of dark matter has been spotted 300 million light years away, and now researchers are looking for one similar to Dragonfly 44 that’s closer […]

Zika could also target adult brains, study of mice suggests. The Zika virus may be even more harmful than once thought, and it may attack adult brains, according to a study of mice brains. Researchers found that adult mice […]

Canyons on Titan carved by rivers of methane. Canyons on Saturn’s moon Titan were carved by rivers of methane in much the same way that water carved the Grand Canyon on Earth. Scientists examined radar images taken by the […]

Evidence of ancient flood uncovered in China . Scientists have uncovered evidence that the myth that an enormous flood spawned China’s Xia dynasty isn’t just legend. Geologists, historians and archaeologists worked together to determine a massive flood occurred around 1,922 […]
