Discovery of Neptune. New Berlin Observatory at Linden Street, where Neptune was discovered observationally. Neptune as imaged by the Voyager 2 probe in 1989. The planet Neptune was mathematically predicted before it was directly observed. With a prediction by Urbain Le Verrier, telescopic observations confirming the existence of a major planet ...
Neptune has been directly explored by one space probe, Voyager 2, in 1989. As of 2024, there are no confirmed future missions to visit the Neptunian system, although a tentative Chinese mission has been planned for launch in 2024. [1] NASA, ESA, and independent academic groups have proposed future scientific missions to visit Neptune.
ICON (Explorer 96) →. Wikinews has related news: NASA launches exoplanet-hunting satellite TESS. Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA 's Explorer program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission.

The James Webb Space Telescope's first images of Neptune, the mysterious ice giant that orbits in the far reaches of the outer solar system, were so New Neptune photos offer rare views of planet ...
The dipole magnetic moment of Neptune is about 2.2 × 10 17 T·m 3 (14 μT·R N 3, where R N is the radius of Neptune). Neptune's magnetic field has a complex geometry that includes relatively large contributions from non-dipolar components, including a strong quadrupole moment that may exceed the dipole moment in strength. By contrast, Earth ...
Heidi B. Hammel (born March 14, 1960) is a planetary astronomer who has extensively studied Neptune and Uranus. She was part of the team imaging Neptune from Voyager 2 in 1989. She led the team using the Hubble Space Telescope to view Shoemaker-Levy 9 's impact with Jupiter in 1994. She has used the Hubble Space Telescope and the Keck Telescope ...
James Webb Space Telescope. 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 ]
Hippocamp (moon) Hippocamp, also designated Neptune XIV, is a small moon of Neptune discovered on 1 July 2013. It was found by astronomer Mark Showalter by analyzing archived Neptune photographs the Hubble Space Telescope captured between 2004 and 2009. The moon is so dim that it was not observed when the Voyager 2 space probe flew by Neptune ...
