The forces of rotation caused red hot masses of stones to be torn away from the Earth and to be thrown into the ether, and this is the origin of the stars.

Could Light Alone Get Us to Another Star?

Universe Today - Tue, 04/28/2026 - 5:43am

Using nothing but a laser beam, scientists at Texas A&M University have demonstrated that tiny engineered devices can be lifted and steered in three dimensions without any physical contact. This breakthrough could one day form the basis of a propulsion system capable of reaching our nearest neighbouring stars in decades rather than centuries.

The Ancient Art That Could Transform Space Communication

Universe Today - Tue, 04/28/2026 - 5:36am

Researchers at the Institute of Science Tokyo have developed an origami inspired foldable antenna for CubeSat satellites that weighs just 64 grams yet in orbit, it deploys to two and a half times its stowed size. The antenna folds away neatly for launch and deploys automatically in space, achieving high gain communications performance from a package small enough to fit in your pocket and could one day support missions as far away as the Moon.

Space Travel May Impact Human Fertility and Fertilization

Universe Today - Tue, 04/28/2026 - 12:35am

Space travel has taught us valuable lessons for living and working in outer space, specifically regarding how microgravity (often mistakenly called zero-gravity) impacts the human body during short- and long-term spaceflight. This includes decreased muscle and bone mass, fluid shifts, reduced heart rate, psychological health, compromised immune system, and radiation exposure. But with agencies like NASA aspiring to build a lunar base and establish a long-term presence on the Moon, and eventually Mars, how could space travel impact potentially having babies in space?

Tiny Ultra-Faint Dwarf Galaxies Reflect The Conditions In The Early Universe

Universe Today - Mon, 04/27/2026 - 4:08pm

The Milky Way has a sizable retinue of dwarf galaxies, and they may hold important clues about conditions in the early Universe. However, they're difficult to observe because many of them are so faint. The tiniest ones are called Ultra-faint dwarf galaxies, and a new simulation aimed at how they form is showing how these faint collections of stars and gas mirror the conditions of the early Universe.

NASA’s Perseverance, Curiosity Panoramas Capture Two Sides of Mars

NASA - Breaking News - Mon, 04/27/2026 - 1:02pm
Learn how NASA’s Curiosity and Perseverance Mars rovers are exploring different chapters of the Red Planet’s ancient history. Credit: NASA/JPL-Caltech/ASU/MSSS/ESA/University of Arizona/JHUAPL/USGS Astrogeology Science Center

NASA’s Curiosity and Perseverance rovers have captured two 360-degree landscapes that highlight how the missions are revealing details of the Red Planet’s formation, watery past, and potential for life. Located 2,345 miles (3,775 kilometers) apart from each other on Mars — about the distance from Los Angeles to Washington, D.C. — both rovers are exploring areas that are billions of years old. But as the nearly 15-year-old Curiosity reaches ever-younger terrain in the foothills of Mount Sharp, the 5-year-old Perseverance is venturing into some of the oldest landscapes in the entire solar system. By time-traveling in opposite directions, the rovers are filling in missing details about the planet’s history.

Stitched together from 1,031 images taken between Nov. 9 and Dec. 7, 2025, Curiosity’s 360-degree panorama offers a detailed look into a region filled with a vast network of boxwork formations: Resembling giant spiderwebs in orbiter images, the low ridges were created by groundwater that once flowed through large fractures in the bedrock. The minerals left behind hardened the rock along the fractures, resulting in erosion-resistant ridges.

Perseverance’s panorama focuses on a place nicknamed “Lac de Charmes,” which sits outside the rim of Jezero Crater. Taken between Dec. 18, 2025, and Jan. 25, 2026, 980 images were stitched together for a 360-degree view capturing the Jezero rim and ancient rocks around the crater.

Driven by Curiosity

Today, both of these landscapes are frigid deserts, but evidence of a more dynamic past hides within. When Curiosity landed on the floor of Gale Crater in 2012, it set out to determine whether Mars once had the conditions to support life. Within a year, a sample drilled from an ancient lakebed confirmed those conditions had been present, including the right chemistry and potential nutrients for microbes.

NASA’s Curiosity Mars rover captured this 360-degree view of a region filled with low ridges called boxwork formations between Nov. 9 and Dec. 7, 2025. At 1.5 billion pixels, this is one of the largest panoramas Curiosity has ever taken.

Since 2014, Curiosity has been ascending Mount Sharp. Towering 3 miles (5 kilometers) above the crater floor, the mountain first began forming when layers of sediment were deposited in a series of lakes. Long after those lakes dried up, ponds and streams returned several times, leaving a record in the mountain’s layers that formed in drier eras. Because the lowest layers are oldest and higher layers are youngest, Curiosity is essentially progressing back through geological time as it slowly climbs the mountain.

Last year, Curiosity’s team documented how they found that the mineral siderite might be storing carbon dioxide that once was part of a thicker, early atmosphere. Scientists had long suspected that carbonate minerals such as siderite formed when carbon dioxide dissolved into ancient lakes, but such deposits had only rarely been found.

The mission also announced the detection of three of the largest organic molecules ever found on Mars in a sample it had drilled in 2013. The discovery of these long-chain hydrocarbons — possibly the remnants of fatty acids — are a milestone in the search for more complex, prebiotic chemistry on the Red Planet.

And this year, they announced that a rock Curiosity drilled and analyzed in 2020 includes the most diverse collection of organic molecules ever found on the Red Planet. Of the 21 carbon-containing molecules identified in the sample, seven of them were detected for the first time on Mars.

Persevering for science

Perseverance landed in Mars’ Jezero Crater in 2021 to study the origin of ancient rocks within the crater and to hunt for evidence that microbial life once existed. Billions of years ago, molten rock cooled to form the floor of Jezero Crater. A river then fed a lake in the crater, leaving behind sediments where traces of microbes could have been preserved. In 2024, the mission discovered a rock nicknamed “Cheyava Falls” that was dotted with “leopard spots,” a pattern formed by chemical reactions that microbes are known to create in rocks here on Earth.

While Curiosity pulverizes its rock samples for analysis, Perseverance collects samples as intact rock cores, each about the size of a piece of blackboard chalk, and stores them in metal tubes. Aside from a backup set of 10 tubes Perseverance deposited in a sample depot, the rover keeps all its samples (23 so far) on board in its interior. Scientists hope to get these samples into labs on Earth where they can investigate them more fully with instruments far bigger and more complicated than those that can be sent to Mars.

Meanwhile, Perseverance continues to investigate other aspects of the Red Planet. For instance, this past fall, mission scientists shared the first recordings of electrical sparks in passing dust devils — a phenomenon that had only been theorized before Perseverance’s microphones caught them. A separate study detailed how one of Perseverance’s sensitive cameras was able to capture the first visible light auroras from the surface of another planet.

Both missions are looking forward to the next discoveries as they continue to unravel the secrets of Mars. Curiosity has left the boxwork region behind as it continues to explore a mountain layer enriched in salty minerals called sulfates; Perseverance will keep heading toward locations that hold exceptionally old terrain, including one called “Singing Canyon.”
