Radio astronomy took another step forward recently, with the completion of Phase III of the Murchison Widefield Array (MWA) in Western Australia. We’ve reported before on how the MWA has investigated everything from SETI signals to the light from the earliest stars. With this upgrade, the MWA will continue to operate with much needed improvements […]

Using ESA’s INTEGRAL spacecraft, astronomers have detected exceptionally bright X-ray flares from the Cygnus X-1 X-ray binary system. This is the first time that such strong flaring activity has been observed in this system although it has been monitored for decades. The new findings were detailed in a paper published August 28 on the pre-print […]

University of Bristol astrophysicists are helping shed new light on an Earth-sized exoplanet 40 light years away where liquid water in the form of a global ocean or icy expanse might exist on its surface. That would only be possible if an atmosphere is present—a big mystery that the scientists are attempting to unravel and […]

Scientists have discovered that Mars has an interior structure similar to Earth’s. Results from NASA’s InSight mission suggest that the red planet has a solid inner core surrounded by a liquid outer core, potentially resolving a longstanding mystery.
