NASA Tests Prototype 3D Printed Titanium Antenna in Space March 3, 2026
With a simple motion, a jack-in-the-box-like spring designed at NASA's Jet Propulsion Laboratory showed the potential of additive manufacturing, also known as 3D printing, to cut costs and complexity for futuristic space antennas. Called JPL Additive Compliant Canister (JACC), the spring deployed on the small commercial spacecraft Proteus Space's Mercury One on Feb. 3, 2026. […]
Adolescence Is Tumultuous, Even For Exoplanets March 3, 2026
Planetary systems such as our solar system take hundreds of millions of years to evolve. But we see most exoplanet systems either very early in their development, or long after the systems have settled down. There's an information gap about what happens in the middle, and a rarely observed "adolescent" system is a valuable opportunity […]
The Coldest "Stars" in the Galaxy Might Actually Be Alien Megastructures March 3, 2026
Ever since physicist Freeman Dyson first proposed the concept in 1960, the “Dyson sphere” has been the holy grail of techno-signature hunters. A highly advanced civilization could build a “sphere” (or, in our more modern understanding, a “swarm” of smaller components) around their host star to harvest its entire energy output. We know, in theory […]
Astronomers Devise a New Way to Measure Cosmic Expansion with Lensed Supernovae March 2, 2026
Researchers in Munich have used the Large Binocular Telescope in Arizona to capture five images of one and the same supernova in a single picture. The gravity of two foreground galaxies has deflected the light from a supernova far in the background along different paths to Earth.
How Saving Earth Could Ruin Orbit March 2, 2026
Satellite imaging is increasingly important to every field from crop monitoring to poverty reduction. So it’s no surprise that there have been more and more satellites launched to try to meet that growing demand. But with more satellites comes more risk for collision - and the debris field that comes after the collision. A new […]
