NASA developing 1st-ever space-based quantum sensor for gravity measurements

NeRD

Scientists are developing an advanced quantum sensor for low Earth orbit that can detect the tiniest tremors in Earth’s gravity. These barely perceptible shifts — caused by moving water, tectonic activity or shifting rock — offer clues about what lies beneath the planet’s surface. The new device could allow the mapping of underground features like aquifers and mineral deposits — crucial data for navigation, resource management and national security, its developers say.

Science Meets Art: NASA Astronaut Don Pettit Turns the Camera on Science

NeRD

4 Min Read Science Meets Art: NASA Astronaut Don Pettit Turns the Camera on Science NASA astronaut Don Pettit is scheduled to return home in mid-April after a seven-month mission aboard the International Space Station as part of Expedition 72. Throughout his stay, Pettit contributed to research that benefits humanity and future space missions. Pettit also shared what he calls “science of opportunity” to demonstrate how experimenting with our surroundings can help gain a better understanding of how things work. This understanding is perhaps enhanced when art, science, and microgravity…

Vast swarms of hidden galaxies may be secretly bathing the universe in a soft glow

NeRD

A secret population of hidden galaxies suffusing the universe in a soft glow of far-infrared light have been strongly suggested to exist, based on careful detective work into some of the most unique data to come from Europe’s Herschel Space Observatory. The galaxies, if they are real, are not necessarily a surprise. The cosmos is filled with light across all wavelengths — it’s just that the far-infrared component seems to be stronger than can be accounted for by all the galaxies we can see in visible light. In other words,…
