This mysterious, starless, gas-rich "failed galaxy" offers a unique glimpse into dark-matter-dominated regions. Situated 16 million light-years away, near Messier 94, Cloud-9 challenges our understanding of galaxy formation, highlighting structures with 5 billion solar masses of dark matter and gas equivalent to 1 million suns, yet lacking stars.
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.
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).
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).
