Asteroids vs Comets vs Meteors vs Meteorites: What Are They and How Are They Different From Each Other?

Asteroids, comets, meteoroids, meteors, and meteorites may seem similar, but each plays a unique role in the Solar System. Asteroids are rocky remnants, comets are icy wanderers, meteors are shooting stars, and meteorites are fragments that survive the plunge to Earth.

Scientists Map Brain Activity Across 95% of the Mammalian Brain in Landmark Study

In a historic collaboration, scientists created the first comprehensive mammalian brain activity map. The project, led by the International Brain Laboratory, analyzed data from 600,000 cells across 139 mice. Findings revealed that decision-making and memory are spread across the brain, not confined to specific regions as previously believed.

Astronomers Discover Stellar Graveyard Filled With Black Hole and Neutron Star Collisions

Astronomers using LIGO-Virgo-KAGRA detected 128 collisions of black holes and neutron stars, including two rare mixed mergers that double previous records. These findings reveal new details of stellar evolution, refine Hubble constant estimates, and test Einstein’s relativity in extreme conditions. The cosmic “graveyard” offers fresh insight into how stars die and black holes grow.
