An effect called strong gravitational lensing has allowed the NASA/ESA Hubble Space Telescope to see the same remote galaxy twelve times. Called PSZ1 G311.65-18.48, the galaxy is almost 11 billion light-years from Earth and has been lensed by a massive foreground galaxy cluster 4.6 billion light-years away.
Although once invisible to us in the vast reaches of the universe, 39 massive ancient galaxies have been discovered by astronomers using multiple space and ground-based observatories. This is the first discovery of its kind, the researchers said.
New measurements from NASA’s Hubble Space Telescope confirm that the Universe is expanding about 9% faster than expected based on its trajectory seen shortly after the big bang, astronomers say.
Astronomers using the NASA/ESA Hubble Space Telescope to study some of the oldest and faintest stars in the globular cluster NGC 6752 have made an unexpected finding. They discovered a dwarf galaxy in our cosmic backyard, only 30 million light-years away. The finding is reported in the journal Monthly Notices of the Royal Astronomical Society: Letters.
A few years ago, the Hubble Space Telescope did something amazing: over the course of 841 orbits and hundreds of exposures, it imaged a tiny region of space in the constellation of Fornax, peeling back the layers of time by 13 billion years, to just a few hundred million years after the Big Bang.
One of the premier cameras on the Hubble Space Telescope is no longer working and NASA has shut it down while the issue is investigated.
The space telescope orbiting Earth has been studying red dwarf flares
New Neptune-sized exomoon candidate has been observed around a star some 8,000 light years away
An unusual infrared emission from the neutron star RX J0806.4-4123 detected by the NASA/ESA Hubble Space Telescope could indicate new features never before seen: one possibility is that there is a disk of material surrounding the neutron star; another is that there is an energetic wind coming off RX J0806.4-4123 and slamming into gas in interstellar space the neutron star is plowing through.
The study, carried out by two researchers at the Instituto de Astrofísica de Canarias, shows that the “change in position” observed in the nucleus of the galaxy M87 is not due to a displacement of its supermassive black hole, but to variations in the emission of light in the centre of the galaxy caused by outbursts coming from its jet, a flow of relativistic material along a narrow beam, emitted from just outside the black hole itself.
