Delta rockets retired with launch of US reconnaissance satellite

The U.S. Space Force and a Boeing-Lockheed joint venture sent a secret reconnaissance payload to orbit on Tuesday atop a Delta IV Heavy rocket, the last flight of a workhorse launch vehicle brand that has logged nearly 400 missions dating back to 1960. The United Launch Alliance-owned rocket, standing roughly 23 stories tall, blasted off from Cape Canaveral Space Force Station in Florida around 1 p.m. EDT (1700 GMT), 12 days after a previous launch attempt was scrubbed at the last minute due to a technical glitch.

UK Nobel Prize-winning physicist Peter Higgs dies aged 94

Physicist Peter Higgs, whose theory of an undetected particle in the universe changed science and was vindicated by a Nobel prize-winning discovery half a century later, has died aged 94, the University of Edinburgh said on Tuesday. The discovery of the Higgs boson in 2012 at the CERN research centre near Geneva was widely hailed as the biggest advance in knowledge about the cosmos for over 30 years, and pointed physics towards ideas that were once science fiction.

Total solar eclipse: North Americans celebrate with cheers, music and matrimony

Throngs of skywatchers across North America gazed upward at a blackened sun in the midday dusk on Monday, celebrating with cheers, music and matrimony the first total solar eclipse to darken the continent in seven years.
