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

Moon rocks could help reveal how life evolved on Earth – and may enable us to resurrect extinct species

Life is the last thing you would associate with the eternally dark craters of the lunar poles. But these craters could hold the key to explaining how complex, multi-cellular organisms evolved on Earth hundreds of millions of years ago, affording unimaginable insights into our planet's biological past.
