Final answer:
Dr. Tight and Dr. Ramirez are observing solar prominences on Jupiter.
Step-by-step explanation:
The solar activity that Dr. Tight and Dr. Ramirez are observing on Jupiter is Solar prominences.
Prominences are spectacular phenomena that usually originate near sunspots and can be seen as red features rising above the Sun. They reach high into the Sun's corona and can remain nearly stable for many hours or even days. Eruptive prominences appear to send matter upward into the corona at high speeds.
