Glossary term: वायुरुप ग्रह (गॅस जायंट)

Description: गॅस जायंट हा एक महाकाय ग्रह आहे जो मुख्यतः हायड्रोजन आणि हेलियमने बनलेला असतो. हे वायू आंतरतारकीय आणि आंतरग्रहीय अवकाशात वायुरूपात आढळतात, म्हणून हे नाव. तथापि, गॅस जायंटमधील बहुतेक हायड्रोजन आणि हेलियम प्रत्यक्षात द्रव स्थितीत आहेत.

गॅस जायंटमध्ये खडकाळ गाभा असतो असे मानले जाते जे हायड्रोजन आणि हेलियमच्या जाड थरांनी वेढलेले असतात. ग्रहाच्या सर्वात खोल भागांमध्ये हे वायू द्रव स्वरूपात संकुचित असतात ज्यामध्ये मेटलिक हायड्रोजनचा (धातूरूपातील हायड्रोजनचा) महासागर असतो असे मानले जाते. बाहेरील थरांमध्ये हायड्रोजन आणि हेलियम वायूच्या स्वरूपात असतात. वातावरणातील इतर घटक ढग आणि पाऊस तयार करू शकतात. सर्वात थंड गॅस जायंटमध्ये वरच्या थरातील ढग पाण्याचे किंवा अमोनियाच्या वाफेचे बनलेले असू शकतात. थंड गॅस जायंटच्या खोल, गरम थरांमध्ये आणि गरम गॅस जायंटच्या बाहेरील थरांमध्ये ढग हे लोह आणि खनिजांचे बनलेले असू शकतात जे साधारणपणे खोलीच्या तपमानावर घन असतात.

सूर्यमालेतील दोन सर्वात मोठे ग्रह, गुरू आणि शनी, हे गॅस जायंट आहेत.

The planet Jupiter with the two of the four Galilean moons (visible as bright dots) orbiting it.

Jupiter's Rotation, by Vishal Sharma, India

Caption: Third place in the 2021 IAU OAE Astrophotography Contest, category Galilean moons: Jupiter’s Rotation, by Vishal Sharma, India. This time-lapse beautifully shows the rotation of Jupiter and the passage of two Galilean moons on the right side of the frame. Jupiter completes one rotation in just under 10 hours and we see as the Great Red Spot makes its way from left to right. The two moons travel a noticeable fraction of their orbit in this short time. This image was taken in 2020 in the North of India.

The planet Jupiter, seen here as a bright disk, is orbited by the four Galilean moons, seen here as bright dots

Jupiter Moons Movie2, by Nicolas Hurez, Paul-Antoine Matrangolo, and Carl Pennypacker, United States of America

Caption: Second place in the 2021 IAU OAE Astrophotography Contest, category Galilean moons. This sequence shows the orbit of the four Galilean moons around the planet Jupiter. Almost two entire orbits of the innermost moon, Io, can be seen, with the other moons (Europa and Ganymede, but in particular Callisto) being further away, orbiting noticeably slower. The images were obtained in 2018 with the Las Cumbres Global Observatory at different locations on Earth, allowing a continuous sequence of images over approximately half a week without gaps during the day. With clear skies and over the course of several nights, the motion of the Galilean moons can also be observed with binoculars (ideally steady your elbows on a surface).

Jupiter with coloured horizontal bands of clouds. The shadow of the moon Io is seen as a dark circle in the top left

Jupiter, Io and its shadow, by Ralf Burkart, Germany

Caption: First place in the 2021 IAU OAE Astrophotography Contest, category Galilean moons. This time-lapse of Jupiter taken in 2017 from Germany beautifully illustrates the transit of one of the Galilean moons, Io, in front of Jupiter. As this is simply a moon casting a shadow on a planet it is equivalent to a lunar eclipse on Earth observed from further away. While the shadow of the moon is clearly visible from the beginning, it might be difficult to spot the moon itself against the background of the beautiful atmospheric bands of Jupiter the first time the video is seen. Watching it repeatedly allows appreciating the rapid motion and rotation in this fantastic observation.

Caption: This full disk view of Jupiter was obtained on 21 April 2014 with Hubble's Wide Field Camera 3 (WFC3). It shows the prominent great red spot, a gigantic cyclone. Cloud ribbons cover the surface, whose colours stem from gases like ammonia and other chemical compounds.

Caption: The NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 observed Saturn on 20 June 2019 as the planet made its closest approach to Earth this year, at approximately 1.36 billion kilometres away. The image shows coloured bands of gas on the planet's surface as well as its prominent rings made of ice and rocky material.
