The Solar System Might Not Exist if There Wasn’t a Huge Galactic Collision with the Milky Way Billions of Years Ago27 May 2020, 21:35 UTC The Milky Way has a number of satellite galaxies; nearly 60 of them, depedending on how we define them. One of them, called the Sagittarius Dwarf Spheroidal Galaxy (Sgr d Sph), may have played a huge role when it comes to humans, our world and our little civilization. A collision between the Milky Way and the Sgr d Sph may have created the Solar System itself.
Universe Today 27 May 2020, 01:17 UTC In a few decades, the Breakthrough Starshot initiative hopes to send a sailcraft to the neighboring system of Alpha Centauri. Using a lightsail and a directed energy (aka. laser) array, a tiny spacecraft could be accelerated to 20% the speed of light (0.2 c). This would allow Starshot to make the journey to Alpha Centauri and study any exoplanets there in just 20 years, thus fulfilling the dream of interstellar exploration within our lifetimes.
Universe Today 26 May 2020, 18:10 UTC What would be the best method for exploring planetary atmospheres, such as at Mars, Venus or even Earth? One group of researchers are developing tiny, levitating “nanocardboard” aircraft that could hover in alien skies. They would fly like dust floating in beams of sunlight – but intelligently, and with a purpose.
The New York Times 25 May 2020, 09:51 UTC Strap a rocket to the underside of a plane. Fly it up several miles. Drop it. The engine ignites, and the rocket and its payload zoom to space. That is what Virgin Orbit, one of the multitude of companies started by Richard Branson, plans to do Monday. It is a demonstration of a new rocket system for sending small payloads to orbit.
