The photos were then mapped onto a sphere, which is then rotated in this video. Mars completes one rotation (a Martian day or “sol”) in approximately 24 hours, 37 minutes. Mars looks reddish due to oxidization of iron in the rocks and regolith (Martian “soil”).

This animation was assembled from a combination of Hubble Space Telescope images of Mars taken from December 28th to 30th, 2024. At the midpoint of the Hubble observations, Mars was approximately 61 million miles from Earth.
This video, produced by the Space Telescope Science Institute, showcases a 3D visualization of Herbig-Haro 49/50 (HH 49/50)—an outflow generated by the jet of a young star in the Chamaeleon I Cloud complex, 625 light-years away.

A synodic month is the period between the same phase (e.g. Full Moon to Full Moon). This is longer because the Earth (and Moon) is also orbiting the Sun. We see two full Moons 29.5 days apart.

The James Webb Space Telescope primary mirror is 6.5 meters (21 feet 4-inches) across. The Hubble Space Telescope primary mirror is 2.4 meters (8-feet) across.
tidal forces or planetary migration the tilts have been changed. The reason why larger planets tend to spin faster is because they took on more of the Sun-orbiting mass, adding the mass's orbital motion to their spin in the process"
The Blue Ghost lander is designed to carry up to 150 kg of payload and is powered by 650W of solar energy. Its landing site is the Mare Crisium region on the Moon's near side. Once there, it will conduct various experiments.

"The radio-wave part of the electromagnetic spectrum travels, like all light, at one fixed speed. And since those same radio waves carry television programs, the programs broadcast earliest have traveled farthest" [from the blog post].
