Hubble captures throng of spiral galaxies
This Hubble Picture of the Week features a richness of spiral galaxies: the large, prominent spiral galaxy on the right side of the image is NGC 1356; the two apparently smaller spiral galaxies flanking it are LEDA 467699 (above it) and LEDA 95415 (v.....»»
Upgraded atomic force microscope captures 3D images of calcite dissolving
Understanding the dissolution processes of minerals can provide key insights into geochemical processes. Attempts to explain some of the observations during the dissolution of calcite (CaCO3) have led to the hypothesis that a hydration layer forms, a.....»»
Hubble traces star formation in nearby nebula NGC 261
NGC 261 blooms a brilliant ruby red against a myriad of stars in this new image from NASA's Hubble Space Telescope. Discovered on Sept. 5, 1826 by Scottish astronomer James Dunlop, this nebula is located in one of the Milky Way's closest galactic com.....»»
Researchers start first low frequency search for alien technology in distant galaxies
The SETI Institute, the Berkeley SETI Research Center and the International Centre for Radio Astronomy Research announced a study using the Murchison Widefield Array (MWA) in Western Australia. Led by Dr. Chenoa Tremblay of the SETI Institute and Pro.....»»
Astrophysicists use AI to precisely calculate universe"s "settings"
The standard model of the universe relies on just six numbers. Using a new approach powered by artificial intelligence, researchers at the Flatiron Institute and their colleagues extracted information hidden in the distribution of galaxies to estimat.....»»
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......»»
Dual-screen laptops make more sense with this spiral notebook-like hinge
Having two laptop screens needn't mean foregoing a built-in keyboard. On the left is Screen B, on the right is Screen A. [credit:.....»»
These colorful diagrams show how air quality has changed in more than 100 countries since 1850
Air pollution is an unseen menace that poses a major threat to human health and the climate. We have created the air quality stripes, a visual tool that captures global air pollution trends, to bring this hidden threat into sharp focus......»»
Hubble spots the Tucana Dwarf in the dark
A splatter of stars glows faintly at almost 3 million light-years away in this new image from NASA's Hubble Space Telescope. Known as the Tucana Dwarf for lying in the constellation Tucana, this dwarf galaxy contains a loose bundle of aging stars at.....»»
Astronomers explore the nature of galaxy NGC 891 with JWST
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby spiral galaxy known as NGC 891. Results of the observational campaign, published August 15 on the preprint server arXiv, provide more insights int.....»»
Study finds European attitudes shifted after Ukraine invasion
An ongoing survey captures how the Russian invasion of Ukraine affected attitudes in European countries not directly involved in the conflict......»»
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......»»
Hubble spots a cluster of emission nebulae within the Large Magellanic Cloud
A bubbling region of stars both old and new lies some 160,000 light-years away in the constellation Dorado. This complex cluster of emission nebulae is known as N11, and was discovered by American astronomer and NASA astronaut Karl Gordon Henize in 1.....»»
New AI tool captures how proteins behave in context
A fish on land still waves its fins, but the results are markedly different when that fish is in water. Attributed to renowned computer scientist Alan Kay, the analogy is used to illustrate the power of context in illuminating questions under investi.....»»
Hubble rings in a new galactic view
The subject of this NASA/ESA Hubble Space Telescope image is situated in the Perseus Cluster, also known as Abell 426, 320 million light-years from Earth. It's a barred spiral galaxy known as MCG+07-07-072, seen here among a number of photobombing st.....»»
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.....»»
New analysis of Webb data measures universe expansion rate, finds there may not be a "Hubble tension"
We know many things about our universe, but astronomers are still debating exactly how fast it is expanding. In fact, over the past two decades, two major ways to measure this number—known as the "Hubble constant" —have come up with different ans.....»»
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......»»
Webb captures new image of gassy baby stars
NASA's James Webb Space Telescope has captured a phenomenon for the very first time. The bright red streaks at top left of this June 20, 2024, image are aligned protostar outflows—jets of gas from newborn stars that all slant in the same direction......»»
