What it is : Oursolar system ’s four elephantine outer planets : Jupiter , Saturn , Uranus and Neptune
Where it is : From about 365 million to 2.8 billion miles ( 587 million to 4.5 billion kilometre ) from Earth
A montage of 10 years of Hubble observations of the giant outer planets
When it was partake in : Dec. 9 , 2024
Why it ’s so special :
This iconic collage boast images of Jupiter , Saturn , Uranus and Neptune captured between 2014 and 2024 as part of theHubble Space Telescope ’s Outer Planet Atmospheres Legacy ( OPAL ) project . Through OPAL , scientists calculate to understand the stunned satellite ' weather conditions and how they shift over time by conduct annual reflexion when the planets are close to Earth . These images allow astronomer to track the atmospherical conditions and dynamics on these planets .
Because of their distance from the sun and different rotational leaning comparative to their orbital axes , the outer planets live seasonal change and atmospherical condition unlike those we ’re used to on Earth . Studying these differences can help astronomers ascertain more about the conditions on planets beyond our solar system of rules .

Jupiter has a 12 - Earth - year domain and a 3 - degree tilt , conduct to limited seasonal change . OPAL ’s images from 2015 to 2024 — particularly those from 2015 , 2019 and 2024 highlighted in the collage — showcase shift cloud structures and theGreat Red Spot ’s deepen position . Astronomers use various filter ( not read here ) to analyze cloud heaviness , gravid storms , altitudes and chemical compositions .
Saturn , on the other hand , is tilted 26.7 degrees on its axis , leading to significant seasonal change . Because it is a ringed organisation , Hubble can capture the hoop edge - on . In these views , the superthin rings almost disappear . This go on every 15 year , with the next event set to come in March and November 2025 . Observations have show subtle changes in Saturn ’s cloud height and winds each year . Its 29 - Earth - year orbit results in seasonal shifts roughly every seven years , with more change expected during each transition .

Uranus has a nearly 90 - academic degree tilt , stimulate it to rotate on its side . As a result of the satellite ’s 84 - ground - year orbit , one hemisphere rest in darkness for 42 Earth old age . Hubble has keep the northern polar cap brighten p.a. as it tilts toward the sun . This style is expected to continue , with theUranian closed chain systemappearing face - on in 2028 .
Neptune ’s OPAL observation revealed two substantial findings . First , orphic colored spots were migrating in an strange fashion , before vanish . secondly , there is a connection between Neptune ’s exchange cloudy weather and the11 - yr solar cycle . Despite receiving only about 1/1000 of the sunlight Earth gets , Neptune ’s weather come along to be influenced by the sunshine .
OPAL will continue to supervise the outer hulk , and the database will keep thrive so that scientists can observe the long - terminal figure change in the planets ' atmospheres . Hubble is predicted to stay on operating into the mid-2030s .
