Hubble captures an angelic merging of galaxies
This week's image from the Hubble Space Telescope show two galaxies which are in the process of merging together, in the system VV-689......»»
Webb finds dwarf galaxies reionized the universe
Using the unprecedented capabilities of the NASA/ESA/CSA James Webb Space Telescope, an international team of scientists has obtained the first spectroscopic observations of the faintest galaxies during the first billion years of the universe. These.....»»
How would an AI turn out if you raised it like a child?
Stick a camera on a child, then feed what it captures to an AI, and it almost works. Enlarge (credit: selimaksan) ChatGPT, arguably the most famous chatbot ever, learned its sometimes human-like conversational skills by.....»»
New measurement captures clearer picture of our galaxy and beyond
With unique capabilities to track microwave energy fluctuations, a small observatory in the Andes mountains of northern Chile produced maps of 75% of the sky as part of an effort to measure the universe's origin and evolution more accurately......»»
Image: Hubble views IC 3476, an active star-forming galaxy
This NASA/ESA Hubble Space Telescope image features IC 3476, a dwarf galaxy that lies about 54 million light-years from Earth in the constellation Coma Berenices. While this image does not look very dramatic—we might say it looks almost serene—th.....»»
Further study of bright gamma-ray burst GRB 230307A shows it was caused by neutron stars merging
An international team of astronomers and astrophysicists has found evidence that the bright gamma-ray burst GRB 230307A observed last year was caused by two neutron stars merging, not from a collapsing massive star. In their study, published in the j.....»»
Astronaut captures stunning images of a snowy Grand Canyon
At the end of his space station mission, Andreas Mogensen has taken time out of his science work to snap some striking photos of a snow-covered Grand Canyon......»»
Astronomers observe the effect of dark matter on the evolution of the galaxies
Dark matter comprises around 85% of all the matter in the universe. Although ordinary matter absorbs, reflects and emits light, dark matter cannot be seen directly, which makes its detection difficult. Its existence is inferred from its gravitational.....»»
JWST sees a Milky Way-like galaxy coming together in the early universe
The gigantic galaxies we see in the universe today, including our own Milky Way galaxy, started out far smaller. Mergers throughout the universe's 13.7 billion years gradually assembled today's massive galaxies. But they may have begun as mere star c.....»»
Black hole fashions stellar beads on a string
Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded. This mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive galaxies, resembling be.....»»
Hubble spots a massive star forming amid clouds of dust and gas
A stunning new image from the Hubble Space Telescope shows the birth of a new, massive star at around 30 times the mass of our sun......»»
Image: Hubble views a massive star forming
This image from the NASA/ESA Hubble Space Telescope is teeming with color and activity. It features a relatively close star-forming region known as IRAS 16562-3959, which lies within the Milky Way about 5,900 light-years from Earth in the constellati.....»»
Even if we can"t see the first stars, we could detect their impact on the first galaxies
For a long time, our understanding of the universe's first galaxies leaned heavily on theory. The light from that age only reached us after traveling for billions of years, and on the way, it was obscured and stretched into the infrared. Clues about.....»»
Image: Sentinel-1 captures Tobago oil spill
Before and after satellite images from the Copernicus Sentinel-1 mission show the scale of the oil spill that occurred off the shores of Trinidad and Tobago's coastline earlier this week. The ship, identified as The Gulfstream, ran aground and overtu.....»»
"Beyond what"s possible": New JWST observations unearth mysterious ancient galaxy
Our understanding of how galaxies form and the nature of dark matter could be completely upended after new observations of a stellar population bigger than the Milky Way from more than 11 billion years ago that should not exist......»»
New NASA mission will study ultraviolet sky, stars, stellar explosions
As NASA explores the unknown in air and space, a new mission to survey ultraviolet light across the entire sky will provide the agency with more insight into how galaxies and stars evolve. The space telescope, called UVEX (UltraViolet EXplorer), is t.....»»
Discovery of unexpected ultramassive galaxies may not rewrite cosmology, but still leaves questions
Ever since the James Webb Space Telescope (JWST) captured its first glimpse of the early universe, astronomers have been surprised by the presence of what appear to be more "ultramassive" galaxies than expected. Based on the most widely accepted cosm.....»»
Image: Spiral galaxy NGC 4254"s dazzling swirls
NGC 4254, a spiral galaxy, is resplendent in orange and blue in this Jan. 29, 2024, image from the James Webb Space Telescope. This is one of 19 nearby spiral galaxies recently imaged by the telescope as part of the long-standing Physics at High Angu.....»»
Which came first: Black holes or galaxies?
Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data suggests......»»
Hubble spots a galaxy shrouded by stars
This NASA/ESA Hubble Space Telescope image shows a densely packed field of stars laid upon a background of dust, gas, and light from more distant celestial objects. There are so many stars in this image's field of view that it may be a little tricky.....»»
Hubble spies baby stars being born amid chaos of interacting galaxies
Amid swirling gas and dust pulled by gravitational forces of interacting galaxies, there can be bursts of star formation, creating new generations of stars......»»
