![]() That effect is illustrated in two images of Mars recently released by NASA, which show the planet at its closest and furthest point from the sun. But Mars's orbit is much more eccentric or oval-shaped than Earth's, meaning conditions differ based on when the planet is closer to the sun. Earth has a relatively circular orbit, so the differences caused by it being slightly closer or further from the sun at different points are minimal. However, there's another factor which also affects weather and conditions on some planets, which is their position in their orbit around the sun. The planets in our solar system experience seasons because of the way that they are tilted in their orbits, so one hemisphere is facing the sun more often at some times of year than others. James Webb spots clues to the large-scale structure of the universe Saturn as you’ve never seen it before, captured by Webb telescope One galaxy, two views: see a comparison of images from Hubble and Webb James Webb spots ancient dust that could be from the earliest supernovas James Webb captures vast structure created by newborn stars The clouds of dust around the stars are warmed by their radiation, with bright infrared sources which Webb is able to pick up on thanks to its infrared instruments. There are a total of around 50 young stars shown in the image, each of them similar to our sun. So the systems in this image include not only new stars but also forming planets as well. ![]() ![]() Eventually, the clumps can gain enough mass to form a solid core, creating the basis for a new planet. Clumps start to form within the disk, beginning with tiny particles and building up to become larger and larger over time. These disks of dust and gas form around a star, gradually growing over time due to the star’s gravity. Several of the stars also have shadows around them which indicate the presence of protoplanetary disks. Stars are the only objects being formed in this image though. This wind blows away material from around the young stars, both preventing other stars from being formed too nearby and also sculpting the dust and gas into distinctive shapes. As stars are formed in the swirl of dust and gas, they give off light and radiation in a phenomenon called stellar wind. The region is made up of multiple star systems, with large amounts of gas such as molecular hydrogen, which is shown in red. It is a relatively small, quiet stellar nursery, but you’d never know it from Webb’s chaotic close-up. The subject is the Rho Ophiuchi cloud complex, the closest star-forming region to Earth. The first-anniversary image from the NASA/ESA/CSA James Webb Space Telescope displays star birth like it’s never been seen before, full of detailed, impressionistic texture. ![]() Located just 390 light-years away, Webb was able to capture the region in stunning detail using its NIRCam instrument. The new image shows a star system called Rho Ophiuchi a busy region where new stars are being born amide swirls of dust and gas. Today marks the one-year anniversary of the first images shared from the James Webb Space Telescope, and to celebrate this milestone NASA has shared yet another gorgeous image of space captured by Webb. ![]()
