Scientists have captured Hubble's largest near-infrared image by using a technique called DASH and combining multiple images together.
A group of researchers working with 3D-Dash will publish their findings in. What makes Hubble’s largest near-infrared image so astonishing is that it captures more than Hubble can typically show in a single image.
With DASH, researchers take up eight pictures per Hubble’s orbit, instead of the standard one image. This allowed them to capture 2,000 hours’ worth of images in just 250 hours. They then combined these images into a single mosaic to create Hubble’s largest near-infrared image ever captured.3D-Dash combines hundreds of images captured by Hubble together to map the entire COSMOS field.
