During eclipses of the Sun, in the moments before the phase of fullness, it appears as a very fine reddish arc, which surrounds the eclipsed disk of the Sun. On its innermost side, it borders the convective zone of the Sun, and on its outermost side, with the chromosphere.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'solar_energy_technology-box-4','ezslot_1',143,'0','0'])};__ez_fad_position('div-gpt-ad-solar_energy_technology-box-4-0'); Observed in the telescope, the photosphere does not appear uniform, but appears to be made up of small, granular-looking cells, called grains of rice. This layer is under constant attack from the X-rays and UV radiation coming from the Sun and the space around us. The sun's atmosphere is made up of several layers, mainly the photosphere, the chromosphere and the corona. The jet stream flows near the border between the troposphere and the stratosphere. Fast winds separate light-colored bands, called zones, from dark-colored bands, called belts. Let us know. The presence of methane in the atmospheres of Uranus and Neptune give the planets their bright blue color.In the lower atmospheres of Jupiter and Saturn, clouds of water, ammonia, and hydrogen sulfide form clear bands. Stratosphere The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. Unlike other layers, which are mostly distinguishable from one another, it is hard to say how far the exosphere is from the surface of the planet. Temperatures in the troposphere decrease with altitude. The greenhouse effect is necessary for life on Earth. Both the stratosphere (next layer down) and the mesosphere are considered the middle atmosphere. The latter value is about halfway to the Moon! Earth's Atmosphere | NASA Space Place - NASA Science for Kids The chromosphere emits a reddish glow as super-heated hydrogen burns off. Explore the sun with NASAs Parker Solar Probe's latest mission news (opens in new tab). An official website of the United States government. That makes it difficult to see without using special instruments. NY 10036. Since the sun is a ball of gas with no solid form, different regions rotate at different rates. That makes it difficult to see without using special instruments. These planets are called gas giants, because they are mostly made of gas and do not have a solid outer crust.Mercury and Mars have some of the right ingredients, but their atmospheres are far too thin to support life.
