NASA Is Launching an ‘Artificial Star’ Into Orbit Around Earth. Here’s Why.
NASA is launching a mini satellite called CubeSat into orbit around Earth in 2029. From its orbital distance of about 22,000 miles, it will appear fixed in the night sky like an “artificial star”. The satellite, called Landolt, is about the size of a breadbox. It will fire lasers that astronomers can use to calibrate […]
‘Immortal’ stars at the Milky Way’s center may have found an endless energy source, study suggests
Stars near the Milky Way’s galactic center appear younger than theories predict based on their properties. This puzzling finding is being investigated. A new study simulations that stars in this region could find an endless energy source by capturing dark matter particles. As these collide and annihilate inside the stars, they release energy. This dark […]
