It is the largest near-infrared image of the sky available to astronomers until the next generation of telescopes launch in the next decade, such as the Nancy Grace Roman Space Telescope and Euclid. This record is likely to remain unbroken by Hubble’s successor, JWST, which is instead built for sensitive, close-up images to capture fine detail of a small area. “It gives us a sneak peek of future scientific discoveries and allows us to develop new techniques to analyze these large datasets.”ģD-DASH covers a total area almost six times the size of the moon in the sky as seen from Earth. “3D-DASH adds a new layer of unique observations in the COSMOS field and is also a stepping stone to the space surveys of the next decade,” says Ivelina Momcheva, head of data science at the Max Planck Institute for Astronomy and principal investigator of the study. DASH creates an image that is eight times larger than Hubble’s standard field of view by capturing multiple shots that are then stitched together into one master mosaic, similar to taking a panoramic picture on a smartphone.ĭASH also takes images faster than the typical technique, snapping eight pictures per Hubble’s orbit instead of one picture, achieving in 250 hours what would previously have taken 2,000 hours. To image such an expansive patch of sky, the researchers employed a new technique with Hubble known as Drift And SHift (DASH). Lamiya Mowla, Dunlap Fellow at the Faculty of Arts & Science’s Dunlap Institute for Astronomy & Astrophysics at the University of Toronto and lead author of the study. Named 3D-DASH, this high-resolution survey will allow researchers to find rare objects and targets for follow-up observations with the recently launched James Webb Space Telescope (JWST) during its decades-long mission. 3D-DASH will allow scientists to find rare objects that the brand new Webb Space Telescope can target for close-up study.Īn international team of scientists recently released the largest near-infrared image ever taken by NASA’s Hubble Space Telescope, enabling astronomers to map the star-forming regions of the universe and learn how the earliest, most distant galaxies originated. For the first time, a complete near-infrared survey of the entire COSMOS field, imaged by the Hubble Space Telescope, is being provided to researchers via 3D-DASH.Īlthough Hubble launched in 1990, a series of five servicing missions have kept it on the cutting edge of technology for the last 30 years. There is a patch of the sky known as the COSMOS field, a region rich with galaxies, that was chosen for the Cosmic Evolution Survey (COSMOS) project.
