Nasa's Parker Solar Probe beams back first insights from sun's edge

Flying closer than any other mission, spacecraft set to unravel the sun's mysteries

Nasa's Parker Solar Probe, which has flown closer to the sun than any spacecraft, has beamed back its first observations from the edge of the sun's scorching atmosphere.

The first tranche of data offers clues to long-standing mysteries, including why the sun's atmosphere, known as the corona, is hundreds of times hotter than its surface, as well as the precise origins of the solar wind.
