Proba-2 watches Mercury transit

Proba-2 watches Mercury transit ESA’s Proba-2 had a ring-side seat for the transit of Mercury on 11 November 2019. Proba-2 monitors the Sun from Earth orbit and was able to spot Mercury’s transit as a small black disc – seen here moving from left to right across the face of the Sun. The images in […]

Beyond the Higgs boson: five reasons physics is still interesting

Beyond the Higgs boson: five reasons physics is still interesting Only physics can burn a hole through the sky. European Southern Observatory (ESO) Andrew Steele, King’s College London Would physics be “far more interesting” if the Higgs boson had not been found? Stephen Hawking thinks so. He made this bold claim, possibly with his tongue […]
