Egyptian boy mummy was buried with a ‘second heart’ made of gold

X-rays have been used to digitally unwrap the mummy of a teenage boy dating back about 2300 years, revealing 49 precious protective amulets, including a gold scarab signifying the heart

NASA image release November 9, 2010 Using data from NASA's Fermi Gamma-ray Space Telescope, scientists have recently discovered a gigantic, mysterious structure in our galaxy. This never-before-seen feature looks like a pair of bubbles extending above and below our galaxy's center. But these enormous gamma-ray emitting lobes aren't immediately visible in the Fermi all-sky map. However, by processing the data, a group of scientists was able to bring these unexpected structures into sharp relief. Each lobe is 25,000 light-years tall and the whole structure may be only a few million years old. Within the bubbles, extremely energetic electrons are interacting with lower-energy light to create gamma rays, but right now, no one knows the source of these electrons. Are the bubbles remnants of a massive burst of star formation? Leftovers from an eruption by the supermassive black hole at our galaxy's center? Or or did these forces work in tandem to produce them? Scientists aren't sure yet, but the more they learn about this amazing structure, the better we'll understand the Milky Way.

This composite image of X-rays from Chandra (colored light blue) and optical data from the Canada-France-Hawaii Telescope (yellow, red, white, and blue) shows a beautiful new look at the compact group of galaxies known as Stephan???s Quintet. One galaxy is thought to be passing through the others at almost two million miles per hour. This generates a shock wave that heats the gas and creates the ridge of X-ray emission detected by Chandra.
