Galaxy cluster ACT-CLJ0102-4915, or “El Gordo” contains the mass of a staggering three million billion suns. It is the largest, hottest, and brightest X-ray galaxy cluster ever discovered in the distant Universe.
The Hubble Space Telescope was used to capture imagery of NGC 5256 (also known as Markarian 266). The interacting galaxies are 350 million light-years from Earth, in the constellation of Ursa Major.
The Very Large Telescope in Chile has taken the deepest spectroscopic survey of space ever, with astronomers focusing on the Hubble Ultra Deep Field.
The results suggest that the outer planets of the system might still harbour substantial amounts of water. This includes the three planets within the habitable zone of the star.
Scientists have discovered the strongest evidence to date for a stratosphere on a planet outside our solar system.
Analyzing a galaxy through a gravitational lens, astronomers obtained images 10 times sharper than Hubble could see on its own.
The next generations will be fed a steady diet of images and discoveries stemming from the Super Telescopes. And the LUVOIR will be front and centre among those ‘scopes.
The aging space observatory, which launched into low Earth orbit on April 24, 1990, kicked off this year's birthday celebration with some dazzling new views of a pair of spiral galaxies.
By using a space-time quirk first predicted by Einstein, the Hubble Space Telescope has also made it clear that our theories to explain the evolving universe are far from complete.
A stunning new image captured by the Hubble Space Telescope shows a galaxy that's being strangled by tentacles of gas and dust. The strange and intricate shape of this celestial object is caused by a supermassive black hole.
Astronomers have performed an accurate census of the number of galaxies in the universe. There are at least 10 times as many galaxies in the observable universe as previously thought.
NASA's Hubble Space Telescope took direct ultraviolet images of the icy moon Europa transiting across the disk of Jupiter. Out of ten observations, Hubble saw what may be water vapor plumes on three of the images.
Two red dwarfs and their accompanying gas giant were discovered through a microlensing event -- but their true nature could only be confirmed by Hubble.
An international team of astronomers crack the case of a mysterious galaxy,Markarian 1018, that has suddenly dimmed after shining brightly for 30 years.
Computer simulations of a spherical collection of stars known as 'NGC 6101' reveal that it contains hundreds of black holes, until now thought impossible.
