An international team of scientists has released the largest near-infrared image taken by the Hubble Space Telescope.. It will help scientists mark regions of star formation in the universe, as well as figure out how the earliest, most distant galaxies formed, according to Phys.. org.

Hubble's research is called 3D-DASH. It will allow scientists to detect rare objects and targets for the latest James Webb telescope..

So far, 3D-DASH has been able to obtain a complete near-infrared survey of the COSMOS field, one of the most data-rich fields for exploring galaxies outside the Milky Way..

This wavelength allows you to see a little more than what is visible to the human eye.. Thanks to this, astronomers can see the most ancient galaxies that are farthest away..

In order to find rare objects in the universe, scientists need to explore large expanses of the night sky.. While such images were obtained from the Earth and suffered from poor resolution, the range of observable objects was limited as a result.. The 3D-DASH project will detect unique phenomena such as the most massive galaxies in the universe, supermassive black holes and galaxies on the threshold of a merger.

In order to get such large images, scientists have applied a new technique known as Drift And SHift (DASH). It allows you to get an image eight times larger than the standard Hubble field of observation.. This is achieved by combining multiple shots similar to the panorama mode of a smartphone photo..

DASH also captures images faster than the standard technique, taking eight photos instead of just one.. Thus, in 250 hours you can get what used to take two thousand.

The Hubble telescope was launched into orbit on April 24, 1990 by the crew of the Discovery space shuttle and has since transmitted millions of unique images to Earth, greatly expanding scientists' understanding of the structure and origin of the Universe.. For a quarter of a century, the device carried out 1.2 million targeted observations of 38 thousand space objects, on the basis of which about 13 thousand scientific papers were prepared. According to experts, "
