![]() The James Webb Space Telescope will use its infrared cameras to see through dust in our universe. Firefighters use infrared cameras to see and rescue people through the smoke in a fire. ![]() This light is called infrared radiation, and we can feel it as heat. The James Webb Space Telescope sees the universe in light that is invisible to human eyes. Infrared cameras can see through dust and smoke. The James Webb Space Telescope is about the same size as a tennis court and about as tall as a 3-story building! Credit: NASA/JPL-Caltech The telescope will unfold, sunshield first, once in space. The Webb telescope is as tall as a 3-story building and as long as a tennis court! It is so big that it has to fold origami-style to fit inside the rocket to launch. Here are some fun facts about the James Webb Space Telescope: It will also be able to observe objects in our solar system from Mars outward, look inside dust clouds to see where new stars and planets are forming and examine the atmospheres of planets orbiting other stars. The telescope will be able to capture images of some of the first galaxies ever formed. It will allow scientists to look at what our universe was like about 200 million years after the Big Bang. The James Webb Space Telescope is the largest, most powerful space telescope ever built.

The research was based on some of the first images taken by JWST in July 2022, as part of the Early Science Release Program CEERS, with imaging processing by Dr Gabriel Brammer (Niels Bohr Institute’s Cosmic Dawn Center at the University of Copenhagen). This initial discovery may just be the start of a transformation in how we make sense of the world around us,” Associate Professor Labbé says. “The James Webb Space Telescope has been a revolution in astronomy, allowing us to see back to the beginning of time. The galaxies were identified using some of the first observations from the USD$10 billion James Webb Space Telescope, the game-changing telescope which was launched in December 2021 and has been in operation since July 2022.Īssociate Professor Labbé is one of two Swinburne researchers leading projects awarded precious time in JWST’s first observation cycle, alongside Distinguished Professor Karl Glazebrook. The power of the James Webb Space Telescope “One alternative, equally fascinating, is that some of the objects belong to a new class of emerging supermassive black holes, never seen before,” Associate Professor Labbé says. “This discovery could transform our understanding of how the earliest galaxies in our Universe formed.”įollow up measurements are being carried out to confirm the galaxies and rule out alternative explanations. This is too big to even exist within current models. “The six galaxies we found are more than 12 billion years old, only 500 to 700 million years after the Big Bang, reaching sizes up to 100 billion times the mass of our sun. “We’ve never observed galaxies of this colossal size, this early on after the Big Bang,” says lead researcher Associate Professor Ivo Labbé from Swinburne University of Technology. The research, published today in Nature, could upend our model of the Universe and force a drastic rethink of how the first galaxies formed after the Big Bang. Using the powerful James Webb Space Telescope, they have observed massive candidate galaxies at the beginning of time, up to 100 billion times the mass of the Sun which, if confirmed, would contain more mass than was thought to exist in the whole Universe at that time.
