NASA SDO: solar prominence, March 2012

The clip shows a dark feature attached to the Sun, recorded in March 2012 by NASA’s Solar Dynamics Observatory. Its title presents the feature as an object the size of Jupiter, but the accompanying explanation identifies it as a solar prominence: dense plasma held above the Sun’s surface by magnetic fields.

The footage therefore shows material connected to the Sun, not a separate object passing nearby. Solar prominences are a known phenomenon; the unusual appearance does not establish that the feature is a Jupiter-sized body.
