Webb, who oversaw the creation of the Apollo program in the 1960s, according to NASA. The telescope is named after one of NASA's early administrators, James E. The James Webb Space Telescope, known as Webb (like "Hubble"), is operated primarily by NASA, which is providing the bulk of the funding, with the European Space Agency (ESA) and the Canadian Space Agency (CSA) as partners.

When you peel back the veil of time as only this new telescope can, these unknown unknowns are certain to be fascinating.Ĭolin Jacobs, Postdoctoral Researcher in Astrophysics, Swinburne University of Technology and Karl Glazebrook, ARC Laureate Fellow & Distinguished Professor, Centre for Astrophysics & Supercomputing, Swinburne University of Technology Just as exciting are the discoveries and questions we can not yet foresee. Over the coming years, JWST’s ability to look so deep and far back into the universe will allow us to answer many questions about how we came to be.

In a patch of dark sky no larger than a fraction of the full Moon there are umpteen thousands of galaxies, really bringing home the sheer scale of the universe we inhabit. The sheer number and variety of sources that the JWST can detect is mind boggling with the exception of a handful of foreground stars, every spot of light represents an entire galaxy. This image ( click here for full view) is a mosaic (many individual images stitched together) centered on the giant Abell 2744 galaxy cluster, colloquially known as “Pandora’s Cluster”. Let’s have a look at ten images that have demonstrated the staggering power of this new window to the universe. But the Webb telescope can see much further into the infrared with greater sensitivity and sharpness. The Hubble telescope continues to be a great scientific instrument and can see at optical wavelengths where the JWST cannot. The JWST is able to probe such sources of light right back to the earliest times, nearly 14 billion years ago. At great enough distances, the light from a galaxy is shifted entirely out of the visible part of the electromagnetic spectrum to the infrared. This ability, when combined with the JWST’s larger mirror, state-of-the-art detectors, and many other technological advances, allows astronomers to look back to the universe’s earliest epochs.Īs the universe expands, it stretches the wavelength of light travelling towards us, making more distant objects appear redder. From this position, away from the interference of our planet’s reflected heat, it can collect light from across the universe far into the infrared portion of the electromagnetic spectrum.
However, while Hubble is in orbit around Earth at an altitude of 335 miles (540 kilometers), the JWST is nearly 1 million miles (1.5 million km) distant, far beyond the Moon.

Like the Hubble Space Telescope, the JWST is in space, so it can take pictures with stunning detail free from the distortions of Earth’s atmosphere.
Launched on Dec, 25, 2021, and fully operational since July 2022, the telescope offers glimpses of the universe that were inaccessible to us before. It is no exaggeration to say the James Webb Space Telescope (JWST) represents a new era for modern astronomy.
