China's FAST Telescope Discovers 19 New Pulsars: Using archival data, researchers identified pulsars located 5,500 to 54,700 light years away by targeting unexplored sky regions. With spin periods ranging from 0.03 to 5.54 seconds, the findings include two potential "switching" pulsars and set a notable record for highly dispersed signals.

China's FAST telescope has scoured the archives to find 19 pulsars missed by previous searches

China's FAST telescope—the largest on Earth—has scoured the archives to find 19 pulsars missed by previous searches, including rare "transient" ghosts. Pulsars (spinning neutron stars) are lighthouses of the cosmos. Most are found near the Galactic Plane, where stars are dense.

"Unique Challenges and Innovative Solutions—An infographic highlights the behavior of fire in microgravity, showcasing its spherical formation, increased risk with higher oxygen levels, and dense smoke issues. The €14 million FireSpace research program aims to tackle these dangers through advanced solutions like acoustic waves, new flame retardants, and sensor technology, with a significant rocket test planned within four years."

New research aims to tame flames for the journey to Mars.

In space, fire doesn't rise. It forms a ghostly sphere that is harder to detect and harder to kill. New research aims to tame flames for the journey to Mars. On Earth, hot air is lighter than cold air. It rises, pulling fresh oxygen in from below. This convection gives fire its familiar teardrop shape and yellow color (soot).

Using powerful ALMA telescope data, researchers uncover secrets beneath Jupiter's moon's icy surface, including a frigid temperature of 133 Kelvin and a potential subsurface ocean. The JUICE mission aims for further study in 2031.

Jupiter's outermost moon is a battered, icy archive of the early solar system.

Jupiter's outermost moon is a battered, icy archive of the early solar system. New thermal imaging is finally peeling back its scarred surface to reveal what lies beneath. Using the ALMA telescope, researchers analyzed thermal data to peer into the top few centimeters of Callisto's surface (regolith).

The Fermi Paradox and the Search for Cosmic Intelligence

This is the heart of the Fermi Paradox, a term for the profound conflict between the sheer statistical probability that we should be surrounded by evidence of intelligent life and the observed reality of a silent, seemingly empty cosmos. For decades, our telescopes and radio receivers have heard nothing but silence.

M dwarf stars (Red Dwarfs)

When you look up at the night sky, the stars that catch your eye are often giants—luminous, massive beacons similar to, or much larger than, our own Sun. It’s natural to think of these bright points of light as typical. But this perception is a profound illusion.

What New Scar on the Moon Teaches Us?

Despite eons of gazing at the "Man in the Moon," many of us miss the fact that our celestial neighbor is still under construction. While the massive, basin-forming impacts ended billions of years ago, the Moon is still struck by asteroids and comets today. Catching these impacts is a challenge, but thanks to the Lunar Reconnaissance Orbiter Camera (LROC), we can now spot fresh craters that appeared almost overnight.
