Scientists have been aware of these lava lamp-esque blobs for decades, but it's only now we're seeing them direct from the source. They were found via a re-examination of 45-year-old data from German-NASA spacecraft Helios 1 and Helios 2 (probes sent to the sun in 1974 and 1976). Using this data PhD student Simone Di Matteo spotted patterns in data consistent with trails of blobs oozing from the Sun. 

The findings were published in JGR Space Physics.
