Ice and carbon dioxide-based frosts also form on Mars, and they can occur farther away from the poles. "Thanks to the Mars Climate Sounder, we can tell these snowflakes would be smaller than the width of a human hair." "Because carbon dioxide ice has a symmetry of four, we know dry-ice snowflakes would be cube-shaped," Piqueux said. Thanks to photographers, we know snowflakes on Earth are unique and six-sided.īeneath a microscope, Martian snowflakes would likely look a little different. Ices can supply planets with carbon, hydrogen, oxygen, nitrogen and sulfur, which could lead to the formation of a habitable planet like Earth, where they are used in planetary atmospheres as well as amino acids, sugars and alcohols. The starlight helped astronomers determine the diverse range of frozen molecules within the Chamaeleon I dark molecular cloud, which is forming dozens of young stars. More orange dots represent light from stars in the background, piercing through the cloud. The journal Nature Astronomy published a study including the image on Monday. A young protostar, called Ced 110 IRS 4, glows in orange to the left. The Webb telescope focused on the Chamaeleon I dark molecular cloud, which appears blue in the new image. Dense clumps within these clouds can collapse to form young stars called protostars. Molecular clouds are interstellar groupings of gas and dust where hydrogen and carbon monoxide molecules can form. In time, the agency may combine more mission raw images in a central place like this page.The James Webb Space Telescope peered inside a wispy molecular cloud located 630 light-years away and spied ices made of different elements. Others are posted on mission websites, such as the Mars rovers Curiosity and Perseverance. Some raw images from NASA missions are posted here. In order to enable everyone to have access to these unprocessed space images soon after they arrive on Earth – sometimes within a couple hours – NASA makes what we call "raw" versions of these images available online. This process usually takes six months to a year from the time images are sent to Earth. They go through a rigorous process called validation, in which they are carefully checked for quality and packaged in a standardized electronic format. However, archival image data products don't show up in the PDS immediately. That means researchers present and future, as well as anyone else, anywhere in the world, can access the data themselves. (You can search for data in the PDS here.) This includes every bit of the original science-quality space image data from NASA missions. For example, a long-lived mission like Cassini could return hundreds of thousands of images over its lifetime.Īll the science data returned by NASA's space missions is permanently archived in the Planetary Data System, or PDS, as a public resource. NASA space missions return lots of images to Earth – far more than featured images the agency posts on the web and in social media. Processed images from these missions are available at the Psyche mission website and Cassini mission website. This image and two others, taken in green and blue light, were combined to create the color view at right. The image was taken using a filter that lets red wavelengths of light pass through to the camera's sensor. At left is an unprocessed, or raw, image from NASA's Cassini spacecraft.
