A view of Saturn's rings from NASA's Hubble Space Telescope captured on June 20, 2019. ... trapping them between the pull of the planet's gravity and their own orbital velocity that wants to fling ...
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 ...
This article is a list of notable unsolved problems in astronomy. Problems may be theoretical or experimental. Theoretical problems result from inability of current theories to explain observed phenomena or experimental results. Experimental problems result from inability to test or investigate a proposed theory.
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]
So maybe it’s best we leave Saturn exploration to uncrewed probes after all. In 2017, NASA’s Cassini probe sent us our closest view of Saturn to date. If you wanted to take a closer look at ...
Hubble Space Telescope image showing part of the Norma cluster, including ESO 137-002. 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.
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 ...
The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy. As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant , or faint for the Hubble Space Telescope . [ 9 ]
