NASA’s MAVEN detects first evidence of lightning-like activity on Mars

While sifting through the extensive data collected by NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft over the last decade, scientists discovered a familiar type of electromagnetic signal commonly caused by lightning. This rare find represents the first direct indication of lightning activity on Mars. The team recently published their findings in Science Advances, where […]

Get ready for the Rubin Observatory’s deluge of discoveries

It’s been about eight months since the Vera Rubin Observatory (VRO) saw first light. Now the telescope is scanning the night sky to detect transient changes and sending alerts to astronomers and observatories around the world so they can perform follow-up observations. This alert system is one of the last milestones before the VRO starts […]

Laser-within-a-laser delivers MeV X-ray radiography in picoseconds

Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) is the hottest place on Earth for the briefest of moments during an experiment. Now, it can be one of the brightest places thanks to the Advanced Radiographic Capability (ARC), NIF’s laser-within-a-laser. How this is possible and how it’s measured is detailed in a paper in Physics […]

The stars that lit up the early Milky Way

Imagine trying to reconstruct the history of a city by studying only its oldest surviving buildings. You can’t watch it being built, you can’t interview the architects, all you have are the structures themselves, their materials, their arrangement, the subtle clues locked into their very fabric. That is essentially what astronomers do when they study […]
