Hubble views a glistening red nebula Westerhout 5
Just in time for the fall foliage season, this image from the NASA/ESA Hubble Space Telescope features a glistening scene in red. It reveals a small region of the nebula Westerhout 5, which lies about 7,000 light-years from Earth. Suffused with brigh.....»»
Growing in molasses: Cosmic large-scale structure caught growing slower than expected
The large-scale structure of the universe—the gigantic, hierarchical cosmic web of structures bound by gravity—is mostly made up of dark matter. The growth of the large-scale structure, from individual galaxies to galaxy clusters, cosmic voids an.....»»
Hubble snaps an autumnal nebula glowing orange from young, hot stars
A new image from the Hubble Space Telescope shows a nebula in the gorgeous colors of autumn, just in time for leaf-changing season......»»
Hubble investigates the gorgeous remnants of a supernova
Scientists are using data from Hubble data of the famous Cygnus Loop supernova remnant to study how these remnants change over time......»»
Saturday Citations: Volcano vs. asteroid; NASA"s supernova time lapse; immortal chemicals
This week, we're highlighting a study involving toxic chemical contaminants, and just for fun, a second study involving other toxic chemical contaminants. But NASA made a cool time-lapse video using the good old Hubble space telescope, and a group of.....»»
NASA"s Perseverance captures dust-filled Martian whirlwind
The lower portion of a Martian dust devil was captured moving along the western rim of Mars' Jezero Crater by NASA's Perseverance rover on Aug. 30, 2023, the 899th Martian day, or sol, of the mission. The video, which was sped up 20 times, is compose.....»»
Living on the edge: Supernova bubble expands in new Hubble time-lapse movie
Though a doomed star exploded some 20,000 years ago, its tattered remnants continue racing into space at breakneck speeds—and NASA's Hubble Space Telescope has caught the action......»»
DECam captures the stunning layers of shell galaxy NGC 3923 and nearby gravitational lensing
Much like humans, galaxies are shaped by the environment in which they form. While no two are exactly alike, they can be divided into three main types: spiral, elliptical and irregular. Of these types, elliptical galaxies are the largest and are thou.....»»
Keck Cosmic Web Imager offers best glimpse yet of the filamentous network that connects galaxies
Like rivers feeding oceans, streams of gas nourish galaxies throughout the cosmos. But these streams, which make up a part of the so-called cosmic web, are very faint and hard to see. While astronomers have known about the cosmic web for decades, and.....»»
Pre-pilot survey explores dozens of candidate ultra-diffuse galaxies
By analyzing the data from the WALLABY pre-pilot survey, astronomers from the University of Western Australia and elsewhere, have inspected 78 candidate ultra-diffuse galaxies in the Eridanus supergroup. The study was detailed in a paper published Se.....»»
Growth of "baby galaxies" witnessed with James Webb Space Telescope
Scientists have theorized how galaxies evolve, but details in their early phase of formation remained shrouded in celestial clouds of mystery......»»
The interaction between AGN and starburst activity as viewed with JWST
With excellent sensitivity and spatial and spectral resolutions, the James Webb Space Telescope (JWST) presents an unprecedented opportunity to promote our understanding of the evolutionary processes of galaxies......»»
Astronomers shed light on evolutionary paths of supermassive black holes and their host galaxies
A new paper entitled "Evolutionary Paths of Active Galactic Nuclei and Their Host Galaxies," published on August 17, 2023, in Nature Astronomy, provides critical new insights on the co-evolution of supermassive black holes and their host galaxies......»»
Hubble peers at peculiar Arp 107 pair
This image taken using the NASA/ESA Hubble Space Telescope's Advanced Camera for Surveys (ACS) shows Arp 107, a celestial object that includes a pair of galaxies in the midst of a collision. The larger object (left) is an extremely energetic type of.....»»
How to merge albums of the same person or pet in Photos for iOS 17
Sometimes the Photos app separates the same person or pet into two different collections, but you can merge them without having to individually drag each photo over. Here's how to do so in iOS 17.Merging photo collections togetherThroughout people's.....»»
Study reveals cosmic surprises about star formation from the dawn of time
A groundbreaking international study has unveiled remarkable insights into the early evolution of galaxies, shedding light on the fundamental processes that have shaped our universe. The findings were published in Nature Astronomy......»»
Astronomers discover newborn galaxies with the James Webb Space Telescope
With the launch of the James Webb Space Telescope, astronomers are now able to peer so far back in time that we are approaching the epoch where we think that the first galaxies were created. Throughout most of the history of the universe, galaxies se.....»»
Astronomers find abundance of Milky Way–like galaxies in early universe, rewriting cosmic evolution theories
Galaxies from the early universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the universe, according to new research published today......»»
Galaxies breathe gas, and when they stop, no more stars form
For most of the history of astronomy, all we could see were stars. We could see them individually, in clusters, in nebulae, and in fuzzy blobs that we thought were clumps of stars but were actually galaxies. The thing is, most of what's out there is.....»»
New faint ultra-diffuse dwarf galaxy discovered
An international team of astronomers reports the detection of a new faint ultra-diffuse dwarf galaxy as part of a systematic wide-area search for faint dwarf galaxies using the Dark Energy Survey (DES). The newfound object, designated NGC 55-dw1, is.....»»
