NASA/ESA’s Hubble Area Telescope has launched a hanging new image of the big galaxy cluster Abell 209, 2.8 billion light-years from us within the Cetus constellation. The large cluster comprises over 100 galaxies held collectively by gravity, however what’s seen is simply half the story. Beneath the shining galaxies is a tangled net of unseen scaffolding—sizzling, diffuse fuel and an enormous quantity of darkish matter. Though invisible, these components outline the universe via their gravitational pull. The robust lenses of Hubble allow scientists to review these invisible components and the twisted spacetime that they create.Technological advancementAccording to NASA web site, the brand new picture was taken with Hubble’s Superior Digital camera for Surveys (ACS) and Extensive Subject Digital camera 3 (WFC3). Twelve exposures taken via totally different shade filters had been mixed to make the complete view. The ultimate image has a golden glow from dozens of vivid elliptical galaxies clustering on the middle, together with a number of blue spiral galaxies on the edges. , Hubble avoids Earth’s blur to make distant galaxies seem pinpoint-sharp . In seen mild, the most important galaxies seem as easy golden orbs, whereas the spiral galaxies shine a faint blue. Hubble demonstrates a technological brilliance by merging optical and infrared knowledge into one hanging cosmic portrait.Scientific revealationsHubble scientists say photos like this might help reply basic questions on darkish matter and darkish power. The area between Abell 209’s galaxies is laced with X-ray–sizzling fuel and dominated by darkish matter. Solely about 5% of the cosmos is strange matter; roughly 25% is darkish matter and 70% is darkish power.An enormous cluster acts like a pure lens: its gravity barely warps the sunshine from extra distant galaxies. Within the Hubble picture, a number of faint background galaxies seem stretched into curved streaks. By measuring these distortions, scientists can map the cluster’s complete mass (together with darkish matter). This lets them check theories about how the universe has grown below the affect of darkish matter and darkish power
