Astronomers Find an X-Ray Key to the Red Dot Mystery

By Carolyn Collins Petersen - May 10, 2026 08:04 PM UTC | Black Holes
Ever since JWST first began peering out at the early Universe a few years ago, astronomers have been spotting strange "little red dots" (LRDs) in its infrared images. There are hundreds of these compact blobs at very high redshifts at distances of about 12 billion light-years. Astronomers think they began forming some 600 million years after the Big Bang. That makes them players in the infancy of the cosmos. They appear red in optical light and blue in the ultraviolet. So, what are these strange objects?

Hubble Capture a Starry Spiral Cosmic Neighbor

By Matthew Williams - May 10, 2026 05:41 PM UTC | Observing
A spiral galaxy seen close up and tilted at an angle, so that its disc fills the view from corner to corner. Its disc is yellow near to the centre and pale blue farther out, showing cooler and hotter stars, respectively. Thin brown clouds of dust, glowing pink spots of star formation, and sparkling blue patches filled with star clusters swirl through the galaxy. Behind it, small orange dots are very distant galaxies.

"Hypergravity" Rewires Biology Over the Long Haul

By Andy Tomaswick - May 10, 2026 12:51 PM UTC | Space Exploration
There’s a specific sequence in the anime Dragonball Z that for some reason has stuck in my head for over two decades. Goku, the main character of the show, travels to King Kai’s planet and can barely stand up when he arrives because the planet’s gravity is 10 times stronger than Earth’s. Over time, he trains in this gravity, and his body begins to adapt to it. Eventually, after leaving the planet, he’s stronger, faster, and more agile than he ever was before. But would that really happen if you were exposed to 10G over a long period of time? Researchers at the University of California Riverside (UCR) decided to test that idea and report their results in a recent paper in the Journal of Experimental Biology. But instead of using anime characters, they used fruit flies as their test subjects.

Saturn’s Icy Rings Likely Formed from Lost Moon "Chrysalis"

By Laurence Tognetti, MSc - May 09, 2026 10:12 PM UTC | Planetary Science
You’re a long-necked Titanosaurs grazing the plains and chomping away on tree leaves about 100 million years ago in the Early Cretaceous in what would eventually become a future Starbucks location. You look up at the night sky and notice a bright dot that seems slightly larger and brighter than usual since you’ve seen it a bunch. You grunt at your cousin (official dinosaur language) asking if he notices it, too. Your cousin grunts back that it does seem bigger and brighter and wonders what’s up.

When Mars Bites Back

By Mark Thompson - May 09, 2026 02:56 PM UTC | Planetary Science
More than 300 million kilometres from the nearest mechanic, NASA's Curiosity rover found itself in a situation that would make any engineer break into a cold sweat. A rock got stuck to its drill and wouldn't let go. What followed was a week long, long distance rescue operation that says as much about the ingenuity of the people behind the machine as it does about the extraordinary challenges of exploring another world.

The Material Science Behind A Spacecraft's Impact Armor

By Andy Tomaswick - May 08, 2026 02:48 PM UTC | Missions
Aerospace engineers have to consider numerous factors when designing a spacecraft, but one that comes up more and more often is the need to design against Micro-Meteoroids and Orbital Debris (MMOD). While most designers understand the threat, designing structural solutions capable of withstanding the hypervelocity impacts these undercontrolled pieces of material can cause can take a significant bite out of a mission’s mass budget. A new paper from Binkal Kumar Sharma of the University of Bremen and Harshitha Baskar, an independent researcher, provides a detailed review of cutting-edge options for defending against those deadly particles.

“Simplified Proteins” Reveal the Biochemical Dawn of Early Earth

By Andy Tomaswick - May 08, 2026 01:17 AM UTC | Astrobiology
When researchers look up at the sky and wonder if we’re not alone, they also realize the origins of life here on Earth might hold the key to finding out. The chaotic chemical soup of our early world eventually led to the staggering complexity of modern life, but how exactly did it start? Proteins were one of the key ingredients in the early years, but we’re still only just discovering how these marvels of modern biology first managed to fold, function, and survive. A new review paper, The borderlands of foldability: lessons from simplified proteins, published recently in Trends in Chemistry, showcases how scientists are attempting to answer this question - by researching “simplified proteins”.

The Asteroid Hunter

By Mark Thompson - May 07, 2026 11:06 PM UTC | Planetary Science
Somewhere out there, hurtling through space in the darkness, is an asteroid with our name on it. We just don't know which one yet. NASA's answer to that uncomfortable truth is NEO Surveyor, a purpose built infrared space telescope currently taking shape in laboratories across America, and scheduled for launch in 2027. The stakes, quite literally, could not be higher.

How Massive Star Clusters Shape Galaxy Evolution

By Evan Gough - May 07, 2026 06:15 PM UTC | Stars
A team of researchers used the NASA/ESA/CSA James Webb Space Telescope together with the NASA/ESA Hubble Space Telescope to observe almost 9,000 star clusters in four nearby galaxies. They studied younger clusters that were still embedded in their natal gas clouds, and older ones that had dissipated that gas. Their results show that more massive star clusters emerge more quickly from their birth, clearing away gas and filling the galaxy with ultraviolet light. The research presents a better understanding of star formation in galaxies, something lacking in scientific simulations, as well as how and where planets can form.

Ringing the GONG: New Details About the Sun's Far-side Activities

By Carolyn Collins Petersen - May 07, 2026 06:00 PM UTC | Solar Astronomy
For years, when something happened on the far side of the Sun, we didn't know much, if anything about it. Sunspots could form there, flares could lash out and the corona could send masses of material out to space. However, we didn't know about any of this until those active regions rotated around to our view. In the late 1900s, scientists came up with a technique called helioseismology to analyze sound waves created by such activity as they echoed through the Sun.

Data Fusion Provides a High-Definition Look At Mars' Temperature Maps

By Andy Tomaswick - May 06, 2026 04:09 PM UTC | Planetary Science
In-situ Resource Utilization (ISRU) is our best bet for “living off the land” for a future Martian base, but tracking down those resources is no easy task. As of now, we have two options - send a rover to a specific location to scout it, or monitor it from orbit. Since rovers are expensive, and there are an absolute ton of sites that we would eventually want to scout, doing so from orbit would seem a better option. But monitoring for temperature, one of the most important orbital scans we can do, is notoriously blurry - based in part on the fact that most of the main instruments used to collect data on it are a few decades old. Now, a paper from researchers at Curtin University in Australia presented at the International Astronautical Congress meeting last September uses a fancy AI-like algorithm to improve that thermal resolution, and, as a result, provided a much better map to some of the most important resources we’ll be looking for.

To Build a City on Mars, We Might Need to Plunder the Asteroid Belt

By Andy Tomaswick - May 06, 2026 03:02 PM UTC | Planetary Science
Rome wasn’t built in a day, and a city on Mars is likely going to take even longer to build than Rome itself. At the time of the first Martian colonists, it is likely that the entirety of humanity’s industrial capacity, including the infrastructure to make critical materials like metals, will be based in the Earth-Moon system. While Mars has some iron, it also lacks many of the materials needed to make advanced materials, like boron and molybdenum. To alleviate that resource bottleneck, a new study, available in pre-print on arXiv and led by Serena Suriano and a team of researchers, offers a workaround that seems obvious in theory but difficult in practice - mine the necessary material from Main Belt asteroids.
