Alan Stern calls these satellite planets, although the term major moon is more common.
For the past few months, Saturn's rings have been appearing thinner and thinner to those using ground telescopes. By March 2025, the rings will disappear entirely from view, according to Earth Sky ...

The Great Attractor is a region of gravitational attraction in intergalactic space and the apparent central gravitational point of the Laniakea Supercluster of galaxies that includes the Milky Way galaxy, as well as about 100,000 other galaxies.

In an image captured by the Hubble Space Telescope, Saturn’s rings display an unexplained phenomenon that looks like spokes moving across its rings.
NASA's Cassini spacecraft, which explored Saturn and its icy moons, including the majestic Titan, ended its mission with a death plunge into the giant ringed planet in 2017. Cassini's radar ...
J1407b is a substellar object, either a free-floating planet or brown dwarf, with a large circumplanetary disk or ring system.It was first detected by automated telescopes in 2007 when its disk eclipsed the star V1400 Centauri, causing a series of dimming events for 56 days.
Gamma rays may be observed directly by satellites such as the Compton Gamma Ray Observatory or by specialized telescopes called atmospheric Cherenkov telescopes. [53] The Cherenkov telescopes do not detect the gamma rays directly but instead detect the flashes of visible light produced when gamma rays are absorbed by the Earth's atmosphere. [60]
