NASA released new glamour shots of our solar system’s outermost planet on Wednesday taken by the James Webb Space Telescope.
The James Webb telescope has captured seven of Neptune’s 14 known moons:Galatea,Naiad,Thalassa,Despina,Proteus,Larissa,and Triton. Neptune’s large and unusual moon,Triton,dominates this Webb portrait of Neptune as a very bright point of light sporting the signature diffraction spikes seen in many of Webb’s images. Webb’s Near-Infrared Camera also revealed the planet’s rings,which have not been seen with this clarity in more than three decades.NASA,ESA,CSA,STScI
The pictures taken in July show not only Neptune’s thin rings,but its faint dust bands,never before observed in the infrared wavelength,as well as seven of its 14 known moons.
Webb showed Jupiter at its best in a series of fresh photos released last month.
Launched less than a year ago,the $10 billion. Astronomers hope to see back to almost the beginning of time when the first stars and galaxies were forming.
NASA’s Voyager 2 was the first spacecraft to see Neptune in all its gaseous glory,during a 1989 flyby.

No other spacecraft have visited the icy,blue planet. So it’s been three decades since astronomers last saw these rings with such detail and clarity,said the Space Science Institute’s Heidi Hammel,a planetary astronomer working with Webb.
Hammel tweeted that she wept when she saw the rings,yelling and making “my kids,my mom,even my cats look”.
,operating 1.6 million kilometres from Earth. It rocketed into space last December.
The observatory is in good health,according to NASA,except for one item.
NASA reported this week that a mechanism on one of Webb’s instruments showed signs of increased friction late last month in one of four observing modes.
Observations are on hold in this one particular observing track,as a review board decides on a path forward.
