Scientists discover the highest energy gamma-rays ever from a pulsar
Scientists using the H.E.S.S. observatory in Namibia have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about 10 trillion times the energy of visib.....»»
What"s the link between gamma ray bursts and supernovae? It might be binary stars
Gamma-ray bursts (GRBs) are some of the most violent events in the universe. Some have a power output equivalent to all of the other stars in the observable universe, at least in the spectrum of gamma rays. But we know very little about them. A new p.....»»
Chinese astronauts may build a base inside a lunar lava tube
Caves were some of humanity's first shelters. Who knows what our distant ancestors were thinking as they sought refuge there, huddling and cooking meat over a fire, maybe drawing animals on the walls. Caves protected our ancient ancestors from the el.....»»
How fast are Arctic glaciers melting? Engineers explored the north with a robot and cameras to find out

New recipes for origin of life may point way to distant, inhabited planets
Life on a faraway planet—if it's out there—might not look anything like life on Earth. But there are only so many chemical ingredients in the universe's pantry, and only so many ways to mix them. A team led by scientists at the University of Wisc.....»»
SLAC fires up the world"s most powerful X-ray laser: LCLS-II ushers in a new era of science
The newly upgraded Linac Coherent Light Source (LCLS) X-ray free-electron laser (XFEL) at the Department of Energy's SLAC National Accelerator Laboratory successfully produced its first X-rays, and researchers around the world are already lined up to.....»»
Possible hints of life found on distant planet. How excited should we be?
Data from the James Webb Space Telescope (JWST) has shown that an exoplanet around a star in the constellation Leo has some of the chemical markers that, on Earth, are associated with living organisms. But these are vague indications. So how likely i.....»»
