LittleSDOHMI | NASA SDO - Planet-sized Bubbles @LittleSDOHMI | Uploaded 12 years ago | Updated 2 hours ago
An intense solar flare observation by yours truly on October 22, 2011. Especially watch the dark "blobs" falling downward into the flare from above. These are not dense blobs of cool matter - they're actually voids
in plasma! Planet-sized bubbles of low density, moving through the 15
million-degree plasma. This warms the cockles of my heart.
