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...

Newly discovered giant planet slingshots around its star

Astronomers have discovered a planet three times the mass of Jupiter that travels on a long, egg-shaped path around its star. If this planet were somehow placed into our own solar system, it would swing from within our asteroid belt to out beyond Neptune. Other giant planets with highly elliptical orbits have been found around other stars, but none of those worlds were located at the very outer reaches of their star systems like this one.
