The Hubble Space Telescope has treated us to another spectacular view of two enormous galaxies locked in a cosmic embrace. The image shows an early stage of a galactic encounter, and the chaotic effect that gravity can have on a grand scale
-
NASA has released an enormous mosaic of the southern sky, stitched together from images captured by the agency’s Transiting Exoplanet Survey Satellite (TESS) over the course of its first year of science observations.
-
The Hubble Space Telescope has captured a creepy cosmic face emerging from the remnants of colliding galaxies. The gleaming eyes represent the central regions of the dueling galaxies, while other features are formed from their tortured disks.
-
Nowadays, the Milky Way is a pretty quiet galaxy – but just a few million years ago its central black hole sent off huge flares of radiation.
-
Hubble has captured a new portrait of the ringed planet Saturn while the gas giant was at its closest point to Earth in its orbit.
-
A new way of bending X-rays raises the prospect of smaller, more powerful X-ray space telescopes. Based on technology originally developed for medical imaging machines, the new design replaces conventional mirrors with a network of micro-engineered plastic prisms.
-
The Hubble Space Telescope has a knack for making us feel incredibly small. The latest image, named the Hubble Legacy Field, is a mosaic of thousands of exposures over the years and constitutes the largest and most comprehensive image ever put together by the Hubble science team.
-
NASA has selected the newest space mission for its Explorer program: the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx). The spacecraft will search for the ingredients of life in the Milky Way, and peer as far as 10 billion years back in time.
-
Astronomers from the Instituto de Astrofísica de Canarias (IAC) have re-processed an old Hubble Ultra-Deep Field (HUDF) image to find new details. The end result is the deepest image ever taken of the universe from space.
-
Hubble appears to be back in working order, with full science operations scheduled to resume by the end of this week. The Wide Field Camera 3 on the aging space telescope was struck by a technical fault on January 8, and NASA engineers now believe they’ve fixed the problem.
-
One of Hubble's cameras has automatically suspended operations due to a fault. While Hubble will continue to scan the skies with its three remaining active cameras, NASA can’t be sure when the telescope will be repaired, due to the ongoing US government shutdown.
-
NASA is poised to send larger and larger telescopes into space over the next couple of decades and a team of researchers at MIT is working out how to use laser-equipped CubeSats to keep them fixed on target.
