. A stunning image captured by scientists at The Australian National University (ANU) and Australias nationwide science company, CSIRO, reveals one of the Milky Ways closest neighbors in brand-new detail.
Lead author of the research study, Dr. Nickolas Pingel, says it is the clearest ever image of hydrogen emitted from the Small Magellanic Cloud.
” The clearness of this image is unmatched,” he said.
” Were able to see all of the small structures for the very first time. Its a crucial action in understanding the role hydrogen plays in the advancement of galaxies.
” For example, you can see holes within the gas. This reveals us that hydrogen interacts with supernovae.”
This research study focused on the Small Magellanic Cloud– the nearest satellite galaxy of the Milky Way.
The group utilized CSIROs ASKAP radio telescope and modern software application to record and process 100 hours of information.
Now they intend to take the project an action further.
” This particular image belonged to a pilot survey,” Dr. Pingel stated.
” Over the next year we are going to gather more observations. Ultimately, well have the ability to connect them and make a huge mosaic which will demonstrate how this galaxy links to its nearby next-door neighbors.”
The research study has actually been released online.

The project becomes part of the Galactic ASKAP (GASKAP) Survey, among several top priority projects to be undertaken with the ASKAP radio telescope. ASKAP is a radio telescope located in Western Australia. It has 36 dish antennas which work together as one telescope and can generate more raw data at a faster rate than Australias whole internet traffic..
CSIRO acknowledges the Wajarri Yamatji as the standard owners of the Murchison Radio-astronomy Observatory website where ASKAP lies.
