Star Betelgeuse - A red supergiant in the constellation Orion

One fascinating star is Betelgeuse, a red supergiant located in the constellation Orion. Here are some intriguing facts about it: 1. Size and Volume: Betelgeuse is immense—if placed at the center of our solar system, it would extend past the orbit of Mars. 2. Variability: It is a pulsating variable star, meaning its brightness changes over time; it has been observed to vary in brightness over several months. 3. Life Cycle: Betelgeuse is nearing the end of its life cycle and is expected to explode as a supernova within the next million years, a relatively short time in astrophysical terms. 4. Distance: It is located approximately 640 light-years away from Earth. 5. Cultural Significance: Betelgeuse has been significant in many cultures and is commonly referred to as the “Shoulder of the Hunter” in the constellation Orion. 6. Color Indicator: Its reddish hue signifies a cooler surface temperature compared to other stars, which gives it a distinctive appearance. Betelgeuse con...

NASA InSight landing on Mars: Milestones

On Nov. 26, NASA's InSight spacecraft will blaze through the Martian atmosphere and attempt to set a lander gently on the surface of the Red Planet in less time than it takes to hard-boil an egg. InSight's entry, descent and landing (EDL) team, based at NASA's Jet Propulsion Laboratory in Pasadena, California, along with another part of the team at Lockheed Martin Space in Denver, have pre-programmed the spacecraft to perform a specific sequence of activities to make this possible.
