No, I don't mean Republican members of Congress. Not quite so far away as Ultima Thule -- in fact only a little over halfway to Pluto -- NASA's Juno orbiter has captured images of a volcanic eruption on Jupiter's moon Io:
And once again, this is something that started before the current regime was installed.
Have we reached the point where our major achievements are in the past?

Four instruments onboard Juno — a camera called JunoCam, the Stellar Reference Unit, the Jovian Infrared Auroral Mapper and the Ultraviolet Imaging Spectrograph — observed Io for over an hour, providing a glimpse of the moon’s polar regions as well as evidence of an active eruption.
JunoCam acquired the new images of Io on December 21, 2018, at 12:00, 12:15 and 12:20 p.m. GMT before Io entered Jupiter’s shadow.
The images show the moon half-illuminated with a bright spot seen just beyond the terminator, the day-night boundary.
“The ground is already in shadow, but the height of the plume allows it to reflect sunlight, much like the way mountaintops or clouds on the Earth continue to be lit after the Sun has set,” said Dr. Candice Hansen-Koharcheck, JunoCam lead from the Planetary Science Institute.
And once again, this is something that started before the current regime was installed.
Have we reached the point where our major achievements are in the past?
