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 ...
Astronomers using the Hubble Space Telescope and the Very Large Telescope have made precise tests of general relativity on galactic scales. The nearby galaxy ESO 325-G004 acts as a strong gravitational lens, distorting light from a distant galaxy behind it to create an Einstein ring around its centre. By comparing the mass of ESO 325-G004 (from ...
The Spitzer Space Telescope is in an Earth-trailing heliocentric orbit drifting away c. 0.1 AU per year. In c. 2013–15 it has passed L 5 in its orbit. Hayabusa2 passed near L 5 during the spring of 2017, and imaged the surrounding area to search for Earth trojans on 18 April 2018. [15]
The ability of gravitational waves to move freely through matter also means that gravitational-wave detectors, unlike telescopes, are not pointed to observe a single field of view but observe the entire sky. Detectors are more sensitive in some directions than others, which is one reason why it is beneficial to have a network of detectors. [47]
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.
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 ...
The moons of the trans-Neptunian objects (other than Charon) have not been included, because they appear to follow the normal situation for TNOs rather than the moons of Saturn and Uranus, and become solid at a larger size (900–1000 km diameter, rather than 400 km as for the moons of Saturn and Uranus).
Viral photo posted to social media upon the conjunction of Jupiter and Saturn was captured via telescope in Massachusetts, using a special technique. Fact check: Images of Saturn, Jupiter are real ...
