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.

Description

NASA’s Curiosity Mars rover used its right navigation camera — one of two on the rover’s mast, or head — to capture the images in this timelapse, which spans six years of driving. The images were snapped between Jan. 2, 2020, and March 8, 2026 (the 2,633rd and 4,830th Martian day, or sol, of the mission, respectively). The images were taken when the mast was looking behind the rover to help the science team choose rocks to study.

Curiosity’s team is using this timelapse to watch for sand grains shifting on the rover’s deck. Distinguishing between sand jostled by each drive and wind gusts can provide new information about seasonal changes in the atmosphere.

Curiosity was built by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California. JPL leads the mission on behalf of NASA’s Science Mission Directorate in Washington as part of NASA’s Mars Exploration Program portfolio.

Astronauts Chris Williams of NASA and Sophie Adenot of the European Space Agency work together in the Kibo laboratory module’s Life Science Glovebox, processing genetic-material samples for the DNA Nano Therapeutics‑3 experiment. The investigation is exploring DNA‑inspired assembly techniques as a way to manufacture treatments—such as chemotherapy and immunotherapy—that can kill cancer cells and activate the immune system.

Tough Fungi Could Survive the Trip to Mars

Universe Today - Tue, 04/28/2026 - 10:03am

NASA and other space agencies spend a lot of time and money considering the cleanliness of their missions. Billions of dollars are spent in and on cleanrooms every year, with the express effort of ensuring both that the equipment operates without interference, but also that we don’t accidentally contaminate our exploration target with life from Earth itself. So far, we have primarily focused on bacteria in our efforts to stop this contamination, but according to a new paper by Atul M. Chander of NASA Jet Propulsion Laboratory and his co-authors, we might be missing an entirely different threat - fungi.

Humanoid robots may be about to break the 100-metre sprint record

New Scientist Space - Cosmology - Tue, 04/28/2026 - 10:00am
Robots can now run a half-marathon faster than humans and are rapidly homing in on the 100-metre sprint record. But why are companies so keen to create speedy robots that have no obvious application in homes or factories?

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?
