A team of researchers led by Zili Shen and Pieter van Dokkum used Hubble Space Telescope to measure the distance of ultra-diffuse galaxy NGC1052-DF2, confirming it lacks dark matter. The results are based on 40 orbits of the telescope and provide crucial implications for estimating the physical properties of the galaxy.
