Hubble Space Telescope Captures World’s Largest Near-infrared Image to Detect Universe’s Farthest Galaxies

An international team of scientists has released the Hubble Space Telescope’s largest-ever near-infrared image ever, allowing astronomers to map the star-forming regions of the universe and learn how the oldest, How did the most distant galaxies form? This high-resolution scan, called 3D-DASH, will allow researchers to detect unusual objects and targets for follow-up studies with the James Webb Space Telescope, which was recently launched on a decade-long mission . 3D-DASH provides researchers with, for the first time, a complete near-infrared survey of the entire COSMOS region, one of the richest data fields for extragalactic probes outside the Milky Way.

Near-infrared instrument astronomers can detect sooner galaxies which is farthest because it is the longest and reddest wavelength observed with Hubble, Until now, such a large image could only be obtained from the ground, and the resolution was poor, limiting what could be seen.

The Hubble Space Telescope, which was launched more than 30 years ago, has sparked a renaissance in the study of the change of galaxies over the past 10 billion years of the universe, according to study lead author Lamia Movala. The 3D-DASH initiative builds on Hubble’s wide-field imaging legacy, allowing researchers to begin unraveling the mysteries of galaxies beyond themselves.

“I’m curious about the monster galaxies, which are the most massive in the universe formed by the merger of other galaxies,” Told Maula.

The researchers used Hubble and a new technique called ‘Drift and Shift’ (DASH) to image such a large part of the sky. DASH captures multiple photographs, which are then stitched together into a master mosaic, which is comparable to shooting a panoramic picture on a smartphone, to create an image eight times larger than Hubble’s regular field of view.

Study lead investigator Evelina Momacheva said that 3D-DASH added a new layer of unique observations to the COSMOS region and was also a step space Surveys of the next decade. This allows researchers to build new tools to examine these vast datasets and gives them a glimpse into future scientific breakthroughs.

Until the next generation of telescopes, such as the Nancy Grace Roman Space Telescope and Euclid, it is the largest near-infrared image of the sky available to astronomers.
