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...

Storms on Jupiter are disturbing the planet's colorful belts

Coordinated observations of Jupiter in early 2017 by six ground-based telescopes and Hubble allowed astronomers to study the evolution of bright plumes and connect them with cloud movements deep in the planet. They show that these plumes originate 80 kilometers below the surface cloud deck and rise up quickly into the stratosphere, where supercooled ammonia freezes to form ammonia ice clouds. The plumes create disturbances in the belts and even change their color.
