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...

New concept for novel fire extinguisher in space

Researchers have developed a new concept of fire extinguishing, named Vacuum Extinguish Method. VEM is based on the 'reverse' operation of the conventional fire extinguishing procedure: It sucks the combustion products, even flame and the firing source itself, into a vacuum chamber to clean up the firing zone. This concept is advantageous for space use, as it prevents the spread of harmful combustible products throughout the enclosed cabin.
