Asteroid deflection technologies

Asteroid deflection technologies are methods and strategies developed to prevent potential impacts of asteroids with Earth. These technologies aim to alter the trajectory of an asteroid to ensure it does not collide with our planet Following the success of NASA's DART (Double Asteroid Redirection Test) mission, discussions about planetary defense and asteroid deflection strategies are increasingly prominent. Here are some principal methods and how they work: 1. Kinetic Impactor:    - How It Works: This method involves sending a spacecraft to collide with an asteroid at high speed. The impact changes the asteroid's velocity and trajectory, ideally enough to avoid a collision with Earth.    - Example: NASA's DART (Double Asteroid Redirection Test) mission successfully demonstrated this technique by impacting the moonlet Dimorphos in 2022. 2. Gravity Tractor:    - How It Works: A spacecraft positioned near an asteroid uses its gravitational pull to...

Dead Stars in Milky Way

It's difficult to determine the exact number of dead stars in the Milky Way galaxy because we can't directly observe all of them. Estimates suggest there are hundreds of billions of dead stars in our galaxy. These dead stars are the leftover remnants after a star has burned through its fuel and undergone a spectacular explosion (supernova) or collapsed in on itself. From vapid findings the numbers are over a million.
