This important balance is necessary to maintain life on Earth. Air pressure at the surface of Titan is higher than on Earth! Of the five officially recognized dwarf planets, Pluto has a thin atmosphere that expands and collapses seasonally, and Ceres has an extremely thin and transient atmosphere made of water vapor.īut only Earth's atmosphere has the layered structure that traps enough of the Sun's energy for warmth while also blocking much of the harmful radiation from the Sun. The moons in our solar system typically have thin atmospheres, with the exception of Saturn's moon, Titan. The smaller, rocky planets - Earth, Venus and Mars - each have thinner atmospheres, hovering above their solid surfaces. The gas giant planets in our solar system - Jupiter, Saturn, Uranus and Neptune - each have a thick, deep atmosphere. The atmosphere of Mercury is extremely thin and is not very different from the vacuum of space. Įach of the planets in our solar system has a uniquely structured atmosphere. Scientists use light spectroscopy to observe the atmospheres of planets and moons in other solar systems. Some planets have active atmospheres with clouds, wind, rain and powerful storms. Each of the planets - and even a few moons - in our solar system have an atmosphere. Beyond the thermosphere is the exosphere, which represents the transition from Earth's atmosphere to space.Įarth is not the only world with an atmosphere. And farthest from the surface we have the thermosphere, which absorbs much of the harmful radiation that reaches Earth from the Sun, causing this layer to reach extremely high temperatures. Its image reveals two dominant features, a darkening toward the outermost regions, called limb darkening, and a fine rice-grain-like structure called granulation. There are so few molecules for light to refract off of that the sky also changes from blue to black in this layer. The photosphere is the portion of the Sun seen in ordinary light. The next layer, the mesosphere, is the coldest because the there are almost no air molecules there to absorb heat energy. Some jet aircraft fly in the next layer, the stratosphere, which contains the jet streams and a region called the ozone layer. We live in the troposphere, the layer closest to Earth's surface, where most clouds are found and almost all weather occurs. Each has characteristic temperatures, pressures, and phenomena. There are several unique layers in Earth's atmosphere. However, there are measurable traces of atmospheric gases beyond this boundary, detectable for hundreds of kilometers/miles from Earth's surface. There is no precise top of the atmosphere, but the area between 100-120 km (62-75 miles) above the Earth's surface is often considered the boundary between the atmosphere and space because the air is so thin here. It gradually gives way to the vacuum of space. I've also found but that doesn't seem to work, giving the error "THREE.CanvasRenderer is not a constructor" and the repository clearly states "THIS IS VERY OLD AND YOU SHOULD NOT USE THIS.The atmosphere becomes thinner (less dense and lower in air pressure) the further it extends from the Earth's surface. This region of the Sun is the first part of the Sun that is visible to us and we call it the photosphere. I've tried a share link from Google Photos and I've tried a URL from within my website. Photosphere The material that reaches the top of the convection zone cools by giving of light. I found and although still works, I cannot figure out what URL I should provide for the image. I'm reluctant to contribute it to a "random" location on Earth as it might result in Google removing it. Unfortunately, I can't do that with this particular photosphere because it isn't of a fixed location - it is inside a cruise ship. The usual solution is to contribute the photosphere to Google Maps and then use their embed facility. I'm trying to embed a photosphere onto my website.
