Dark matter has always been a perennial mystery to scientists. A new study has unraveled the enigma behind galaxy NGC1052-DF2، as the Technical Times said.
The DF2 or the "galaxy without dark matter" is about the same size as Milky Way but appears as an ultra-diffuse one with fewer stars (100 to 1،000 times lesser) compared to Earth's galaxy.
Apparently، the DF2 is closer to Earth than what was previously thought by astronomers. When the galaxy was discovered last year، scientists estimated its distance at about 65 million light-years away in the constellation Cetus.
Researchers from the Instituto de Astrofísica de Canarias in Tenerife، Spain now claim that the previous assumptions and estimates were anomalous. New calculations and more accurate estimates reveal that the galaxy would be around 42 million light years away.
This significant information places the distance of DF2 as normal and within "the observed trends traced by galaxies with similar characteristics."
