Around five years ago, NASA’s Fermi Gamma-ray Space Telescope detected high-energy gamma rays coming from TXS 0128+554, an elliptical galaxy located some 500 million light-years away in the constellation of Cassiopeia. Purdue University’ Professor Matthew Lister and colleagues have since taken a closer look using NSF’s Very Long Baseline Array (VLBA) and NASA’s Chandra X-ray Observatory.
Now we just need to find a galaxy shaped like an X-wing fighter.

An international team of archaeologists has found and studied 104 enigmatic stone structures called ‘mustatils’ in the southern part of the Nefud Desert in northern Arabia. They’ve also provided the first chronometric age estimate for this type of structure — a radiocarbon date of 5000 BCE — and described their landscape positions, architecture and associated culture.
