The plentiful but enigmatic material that does not emit light or energy is called dark matter. Even though it is invisible, it is considered as a fundamental part of all galaxies including our own Milky Way.

Why is mysterious dark energy leading to expansion of the universe?

The National Aeronautics and Space Administration has said that the Hubble Space Telescope returned to full science operations and captured images of two unusual galaxies.

The Hubble Space Telescope is damaged, and NASA is scrambling to figure out what's wrong with the workhorse observatory's most significant problem in almost a decade.

Down for a month: NASA faces Hubble Space Telescope's most serious glitch in years

The Hubble Space Telescope, which has been peering into the universe for more than 30 years, has been down for the past few days, NASA said Friday. The problem is a payload computer that stopped working last Sunday, the US space agency said.

Astronomers have discovered cosmic dust that holds the ingredients for star birth throughout the universe, in the latest study. The study published in 'The Astrophysical Journal' on Friday highlights how NASA's Hubble Space Telescope has photographed a concentration of elements that are responsible for the formation of stars in our galaxy and throughout the universe.

The National Aeronautics and Space Administration (NASA) on Tuesday captured the 'magnetic fingerprint' of a galaxy across 24,000 light-years. The mesmerising image depicts magnetic fields in galaxy NGC 1068 or M77, streamlining over visible light and X-ray composite image of the galaxy from the Hubble Space Telescope, NuSTAR or the Nuclear Spectroscopic Array, and the Sloan Digital Sky Survey.

The National Aeronautics and Space Administration (NASA) has captured the largest and one of the most complete Einstein rings ever discovered in our universe. Named GAL-CLUS-022058s, the Einstein ring is located in the southern hemisphere constellation of Fornax (the Furnace) and was captured by Hubble Space Telescope.
