Hubble captures unique ultraviolet view of a spectacular star cluster
Roughly 210,000 light-years away, the Small Magellanic Cloud (SMC) is one of our Milky Way galaxy's closest neighbors. In fact, this small galaxy is one of the Milky Way's "satellite" galaxies, which orbit our home spiral galaxy......»»
Watch a star get destroyed by a supermassive black hole in the first simulation of its kind
Giant black holes in the centers of galaxies like our own Milky Way are known to occasionally munch on nearby stars......»»
New simulations shed light on stellar destruction by supermassive black holes
Monash University astronomers have contributed to a breakthrough in understanding the dramatic fate of stars that wander too close to supermassive black holes at the centers of galaxies......»»
Researchers discover smarter way to recycle polyurethane
Researchers at Aarhus University have found a better method to recycle polyurethane foam from items like mattresses. This is great news for the budding industry that aims to chemically recover the original components of the material—making their pr.....»»
Dark Energy Camera probes the Coma Cluster, an inspiration for the theory of dark matter
The Dark Energy Camera has captured an image of the dazzling Coma Cluster, named after the hair of Queen Berenice II of Egypt. Not only significant in Greek mythology, this collection of galaxies was also fundamental to the discovery of the existence.....»»
Astronomers find galaxies in denser environments are as much as 25% larger than those in less dense regions
A team of astronomers using a Yale supercomputer have determined for the first time that galaxies in denser environments are as much as 25% larger than their counterparts in less dense regions of the universe......»»
Are Andromeda and the Milky Way doomed to collide? Maybe not
Scientists discovered the Andromeda galaxy, known as M31, hundreds of years ago, and around a century ago, we realized that it had negative radial velocity toward the Milky Way. In other words, eventually, the two galaxies would merge spectacularly......»»
NASA Retires Asteroid-Hunting Telescope
NASA’s NEOWISE telescope has searched for asteroids, brown dwarfs and luminous galaxies. The spacecraft will soon burn up in Earth’s atmosphere.....»»
Hubble images a pair of tiny dwarf galaxies
A pair of new Hubble images show small dwarf galaxies, one of which is thought to be the result of a historical merger......»»

Researchers reveal parsec-scale radio emission properties of dual AGNs by multi-phase-center VLBI observations
Galaxy mergers play a crucial role in the cosmological evolution of galaxies. During galaxy merging, tidal torques can trigger the accretion and feedback of the central black holes in merging galaxies, forming dual active galactic nuclei (AGNs)......»»
Surprising ring sheds light on galaxy formation
The question of what triggers the extremely rapid star formation within Hyper Luminous Infrared Galaxies (HyLIRGs), as yet unknown, is of much interest to guide our understanding of the formation and evolution of galaxies in the universe. A new photo.....»»
It Will Soon Be Easier for Americans to Recycle Batteries
Improperly discarded batteries leak toxic chemicals and are prone to exploding. A new program funded by the Department of Energy will prop up battery drop-off sites across the US......»»
Webb Space Telescope"s latest cosmic shot shows pair of intertwined galaxies glowing in infrared

Vivid portrait of interacting galaxies marks Webb"s second anniversary
A duo of interacting galaxies commemorates the second science anniversary of NASA's James Webb Space Telescope, which takes constant observations, including images and highly detailed data known as spectra. Its operations have led to a "parade" of di.....»»
Hubble measures the distance to a supernova
Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it's a difficult one to complete......»»
