Researchers have monitored #Neptune for over 30 years with the #Keck Observatory (since 2002), the Lick Observatory (2018-2019), and the #Hubble Space Telescope (since 1994).

One neat result comes out of this data. The number of clouds on Neptune seems to be correlated with the solar cycle. The sun puts out the maximum amount of ultraviolet light during the solar cycle's peak. Two years later, more clouds appear on Neptune.

Neptune observed with NIRC2 on the Keck telescope at 1.63 microns from 2002 through June 2023. Grid of 15 images of Neptune, a blue, spherical planet with white clouds which form horizontal bands across its surface. The cloud cover in each image varies. The images from 2002 through 2017 have more clouds and the images from 2019 through 2023 have fewer clouds.

When an object falls toward a black hole, it gets horribly stretched and distorted--a process called "spaghettification."
And we can see this process happening right now at the center of our galaxy. https://www.keckobservatory.org/x7/ #BlackHole #space
