Size comparison of Jupiter with Ditsö̀ WASP-17b has a radius between 1.5 and 2 times that of Jupiter and about half the mass . [ 1 ] Thus its mean density is between 0.08 and 0.19 g/cm 3 , [ 1 ] compared with Jupiter's 1.326 g/cm 3 [ 14 ] and Earth 's 5.515 g/cm 3 (the density of water is 1 g/cm 3 ).
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 ]
WASP-96b's spectrum was one of the images featured in the initial science release from the James Webb Space Telescope in July 2022. [4] The spectrum confirmed the presence of water, as well as providing evidence for "clouds and hazes" within the planet's atmosphere. [3] Prior to this discovery, WASP-96b was thought to be free of clouds. [5] [6]
Astronomers used the James Webb Space Telescope to newly detect a high-speed jet stream over the equator of Jupiter. Webb telescope spots never-before-seen feature in Jupiter’s atmosphere Skip ...
A super Jupiter has been spotted around a neighboring star by the Webb Space Telescope — and it has a super orbit. The planet is roughly the same diameter as Jupiter, but with six times the mass ...
The James Webb Space Telescope’s first images revealed new details of the cosmos, peering farther into space than the Hubble Space Telescope.
An observation of the secondary eclipse of TRAPPIST-1b by the James Webb Space Telescope, announced in March 2023, suggested that the planet does not have any significant atmosphere. [8] [9] Atmospheres containing carbon dioxide with surface pressures greater than 0.1 bar can be ruled out at 3-sigma, and pressures greater than 0.01 bar at 1 ...
LHS 475 b is a terrestrial planet orbiting the star LHS 475 which is about 40.7 light years away, in the constellation of Octans. [2] [3] It was the first extrasolar planet to be confirmed by the James Webb Space Telescope. [4]
