NASA Scientists Find New Human-Caused Shifts in Global Water Cycle
2025.01.16
In a recently published paper, NASA scientists use nearly 20 years of observations to show that the global water cycle is shifting in unprecedented ways. The majority of those shifts are driven by activities such as agriculture and could have impacts on ecosystems and water management, especially in certain regions.
NASA’s Hubble Traces Hidden History of Andromeda Galaxy

NASA Celebrates Edwin Hubble’s Discovery of a New Universe
2025.01.15
For humans, the most important star in the universe is our Sun. The second-most important star is nestled inside the Andromeda galaxy. Don’t go looking for it — the flickering star is 2.2 million light-years away, and is 1/100,000th the brightness of the faintest star visible to the human eye. Yet, a century ago, its […]
NASA’s Webb Reveals Intricate Layers of Interstellar Dust, Gas
2025.01.14
Once upon a time, the core of a massive star collapsed, creating a shockwave that blasted outward, ripping the star apart as it went. When the shockwave reached the star’s surface, it punched through, generating a brief, intense pulse of X-rays and ultraviolet light that traveled outward into the surrounding space. About 350 years later, […]
Smoke Streams from Palisades and Eaton Fires

Several plumes billowed from Los Angeles-area fires in the days after their ignition.
New Simulated Universe Previews Panoramas From NASA’s Roman Telescope
2025.01.14
Astronomers have released a set of more than a million simulated images showcasing the cosmos as NASA’s upcoming Nancy Grace Roman Space Telescope will see it. This preview will help scientists explore a myriad of Roman’s science goals. “We used a supercomputer to create a synthetic universe and simulated billions of years of evolution, tracing […]
Newfound Galaxy Class May Indicate Early Black Hole Growth, Webb Finds
2025.01.14
In December 2022, less than six months after commencing science operations, NASA’s James Webb Space Telescope revealed something never seen before: numerous red objects that appear small on the sky, which scientists soon called “little red dots” (LRDs). Though these dots are quite abundant, researchers are perplexed by their nature, the reason for their unique […]
Hubble Reveals Surprising Spiral Shape of Galaxy Hosting Young Jet
2025.01.13
The night sky has always played a crucial role in navigation, from early ocean crossings to modern GPS. Besides stars, the United States Navy uses quasars as beacons. Quasars are distant galaxies with supermassive black holes, surrounded by brilliantly hot disks of swirling gas that can blast off jets of material. Following up on the groundbreaking 2020 discovery of […]
NASA’s Hubble Tracks Down a ‘Blue Lurker’ Among Stars
2025.01.13
The name “blue lurker” might sound like a villainous character from a superhero movie. But it is a rare class of star that NASA’s Hubble Space Telescope explored by looking deeply into the open star cluster M67, roughly 2,800 light-years away. Forensics with Hubble data show that the star has had a tumultuous life, mixing […]
Webb Watches Carbon-Rich Dust Shells Form, Expand in Star System
2025.01.13
Astronomers have long tried to track down how elements like carbon, which is essential for life, become widely distributed across the universe. Now, NASA’s James Webb Space Telescope has examined one ongoing source of carbon-rich dust in our own Milky Way galaxy in greater detail: Wolf-Rayet 140, a system of two massive stars that follow […]
Astronomers Catch Unprecedented Features at Brink of Active Black Hole
2025.01.13
