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...

Unusual supernova opens a rare window on the collapse of a star

An unusual supernova studied by multiple telescopes, including the SOAR telescope and other telescopes at the National Science Foundation's (NSF) Cerro Tololo Inter-American Observatory (CTIO) and NSF's Kitt Peak National Observatory (KPNO), is thought to herald the birth of a new black hole or neutron star, caught at the exact moment of its creation. Observations made with facilities ranging from X-rays to optical and radio wavelengths were used to understand this remarkable event. These multi-messenger observations give astronomers a rare glimpse into the physics at play during the creation of a black hole or neutron star.
