The NASA/ESA Hubble Space Telescope has imaged the majestic spiral galaxy UGC 2885, which may be the largest known in the local universe. It is 2.5 times wider than our Milky Way and contains 10 times as many stars.
The NASA/ESA Hubble Space Telescope has once again captured comet 2I/Borisov streaking through our Solar System on its way back into interstellar space. At a breathtaking speed of over 175 000 kilometres per hour, Borisov is one of the fastest comets ever seen.
New observations from the NASA/ESA Hubble Space Telescope have investigated the nature of the gamma-ray burst GRB 190114C.
Astronomers using the NASA/ESA Hubble Space Telescope have observed a galaxy in the distant regions of the Universe which appears duplicated at least 12 times on the night sky. This unique sight, created by strong gravitational lensing, helps astronomers get a better understanding of the cosmic era known as the epoch of reionisation.
In celebration of Halloween, this new image from the NASA/ESA Hubble Space Telescope captures two galaxies of equal size in a collision that appears to resemble a ghostly face. This observation was made on 19 June 2019 in visible light by the telescope's Advanced Camera for Surveys.
On 12 October 2019, the NASA/ESA Hubble Space Telescope provided astronomers with their best look yet at an interstellar visitor – Comet 2I/Borisov – which is believed to have arrived here from another planetary system elsewhere in our galaxy.
The NASA/ESA Hubble Space Telescope has produced a new resource for astronomers: the Hubble Catalog of Variables (HCV), which is the first full, homogeneous catalogue of variable sources based on archival data from the iconic observatory.
The NASA/ESA Hubble Space Telescope's Wide Field Camera 3 observed Saturn on 20 June 2019 as the planet made its closest approach to Earth this year, at approximately 1.36 billion kilometres away.
With data from the NASA/ESA Hubble Space Telescope, water vapour has been detected in the atmosphere of a super-Earth within the habitable zone by University College London (UCL) researchers in a world first.
Just as people of the same age can vary greatly in appearance and shape, so do collections of stars or stellar aggregates. New observations from the NASA/ESA Hubble Space Telescope suggest that chronological age alone does not tell the complete story when it comes to the evolution of star clusters.
