Medicine & TechnologyThe most accurate distance measurement yet of ultra-diffuse galaxy NGC1052-DF2 confirms beyond any shadow of a doubt that it is lacking in dark matter.
Because it dwells in the galactic plane, where it may easily be covered by the Milky Way's 400 billion stars, the stellar stream has stayed hidden from astronomers for a long time.
Space agencies NASA and ESA released a new image taken by the Hubble Space Telescope of the spiral galaxy NGC 691, the eponymous galaxy for the galaxy group where it belongs.
"Downtown" space is just about 25,800 light-years away, a short hop in cosmic distances. A light year is the number of years that light travels, in this case to reach the Earth.
Scientists have traced the locations of multiple mysterious fast radio bursts back to their origins – particularly the spiral galaxy arms – with help from the Hubble Space Telescope.
Vast halo of dark matter around Tucana II is said to be five times larger than previously estimated. The dwarf galaxy is 163,000 light years from Earth.
According to scientists, a lost galaxy believed to be gone is not really lost. Will Roman Space Telescope capture such photos better than NASA's Hubble Space Telescope?
NASA satellites detected a giant flare was detected in April as it swept past Mars. Experts say it came from a powerful neutron star 11.4 million light-years away.
