There is a signal, born in the earliest days of the cosmos. It’s weak. It’s faint. It can barely register on even the most sensitive of instruments. But it contains a wealth of information about the formation of the first stars, the first galaxies, and the mysteries of the origins of the largest structures in the Universe. Despite decades of searching for this signal, astronomers have yet to find it. The problem is that our Earth is too noisy, making it nearly impossible to capture this whisper

Observations by the keen-eyed Webb Space Telescope have revealed a huge galaxy in the distant—which is to say early—universe. The galaxy is a vibrant orange disk, dubbed the Big Wheel. Its life began within the universe’s first two billion years of existence; given the cosmos’ near-14-billion-year existence, that’s quite old. The galaxy is remarkably developed for appearing so early in time, raising new questions about how galaxies form. The team’s research, published this week in Nature Astro

What just happened? The European Space Agency's Euclid mission released its first batch of survey data this week, providing a glimpse of hundreds of thousands of galaxies in diverse shapes and sizes, as well as numerous galaxy clusters, active galactic nuclei, and transient phenomena like supernovae and gamma-ray bursts. The data covers a substantial area of the sky in three mosaics, showcasing the mission's capability to explore the large-scale organization of galaxies within the cosmic web. "

Although DR1 is just a fraction of what DESI will eventually produce, the 270-terabyte dataset represents a staggering amount of information, including precise distances to millions of galaxies. The release contains more than twice as many extragalactic objects (those found outside our galaxy) as have been collected in all previous 3D surveys combined. Within its first year of operations, DESI became the single largest spectroscopic redshift survey ever conducted, sometimes capturing data on mo

The Euclid space telescope is on a mission to map more than one third of the entire sky, observing billions of galaxies over a span of six years to gather data about the universe’s dark side. In its first big data release, the telescope produced a beautiful mosaic of millions of distant galaxies with different shapes and sizes, giving us a glimpse of its power to peer into the cosmos. On Wednesday, the European Space Agency (ESA) released the first catalog of data from the Euclid space telescop

A researcher has made a puzzling discovery while analyzing observations taken by NASA's James Webb Space Telescope. While analyzing images for the telescope's Advanced Deep Extragalactic Survey (JADES), Kansas State University associate professor of computer science Lior Shamir found that out of the 263 galaxies examined, two thirds of them rotated clockwise, while only a third rotated counterclockwise, as detailed in a paper published in the journal Monthly Notices of the Royal Astronomical So

One researcher’s analysis of Webb Space Telescope images could indicate that we’re all stuck in a black hole, according to research published in the Monthly Notices of the Royal Astronomical Society. “The main finding of the study is that the vast majority of the galaxies in the universe, as seen from Earth, rotate in the same direction,” explained Lior Shamir, an astronomer at Kansas State University and lead author of the study, in an email to Gizmodo. “That adds another observation that disa

A group of astronomers has discovered the smallest, dimmest satellite galaxy bordering the Milky Way’s nearest galactic neighbor, the Andromeda Galaxy. The itsy-bitsy satellite galaxy is named Andromeda XXXV and sits about 3 million light-years from Earth. The discovery of the galaxy gives astronomers a useful comparative tool for studying satellite galaxies on the outskirts of our own galaxy, the Milky Way. The team’s findings were published this week in The Astrophysical Journal Letters. “It

What just happened? NASA's latest observatory is preparing for a two-year mission to create a 3D map of the entire celestial sky. SPHEREx, which is short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, launched into space aboard a SpaceX Falcon 9 rocket that left Vandenberg Space Force Base in California at 8:10 pm Pacific on March 11. Following a checkout period lasting one month, the observatory – which measures 8.5 feet tall, 10.5 feet across,

A new NASA space observatory is scheduled to launch into orbit this week on a lofty mission to map more than 450 million galaxies. The SPHEREx mission (short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) will map the entire sky four times over two years, offering scientists a chance to study how galaxies form and evolve, and providing a window into how the universe came to be. NASA’s SPHEREx observatory undergoes testing at BAE Systems in Boul

Gravitational lenses are rare in the sky – galaxies bending the light-paths of light from other galaxies behind them to form distorted or even multiple images. Even rarer is a perfect alignment of the two galaxies with us, the obervers, with the light being bent into a so-called Einstein Ring. And the rarest case was now observed by Euclid: this happening in an extremely nearby NGC galaxy. Gravitational lensing is the effect of mass bending space and light following along this bent space.
