The gas rings that form the birthplace of planets also light up in the infrared. The Carina Nebula – stars will form in the dust filled orange region below JWST’s infrared observations will provide new detail about star formation in these objects. Infrared light, however, has a longer wavelength than optical or ultraviolet so it can pass through this obscuring dust unaffected. ![]() However, these regions are often very dusty which scatters visible and UV light, hiding potential clues about how star formation occurs in these nebulae. ![]() This stellar nursery is home to countless stars, many of which are several times larger than the Sun. Located at around 7600 light years from Earth in the Carina constellation, the Carina Nebula is one of the largest and brightest nebulae in the sky. Stephan’s Quintet flowing with red coloured gas and dust By studying objects like Stephan’s Quintet, JWST will help us understand how galaxies, and the supermassive black holes at their centers, form and grow. Interactions like these are one of many factors that can shape how galaxies change across cosmic time. Four out of the five galaxies in this group are caught in a cosmic dance of repeated close encounters. A particularly dramatic example of this, located at around 290 million light years away, is Stephan’s Quintet. Galaxies can exist in many different environments. Exploiting this process of gravitational lensing is one of several ways that JWST will image the conditions of the early Universe and try to understand more about how the first stars and galaxies formed. The sheer density of matter distorts space and magnifies light originating from distant galaxies that are behind it but lie along the same line of sight. These massive objects are useful in observing the conditions in the early Universe. Unveiled by President Biden yesterday, this snappily named object is a nearby galaxy cluster. Infrared images of five objects have been shared in the initial public release highlighting the many scientific problems that JWST will address. This was taken on the Fine Guidance Sensor, the instrument built by the Canadian Space Agency which allows JWST to point precisely and take high-quality images. It covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground.Īlso, the Canadian Space Agency shared a teaser image last week, showing numerous stars and galaxies observed for over 32 hours. Centered on the galaxy cluster SMACS 0723, the cluster contains thousands of galaxies – including the faintest objects ever observed in the infrared – which have appeared in Webb’s view for the first time. Last night, US president Joe Biden unveiled the first image: a false-colored infrared view of Webb’s First Deep Field. ![]() This comes after a week of preview images being released. After nearly three decades in the planning, NASA have published the first images from the James Webb Space Telescope (JWST).
