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 observations of black hole devouring a star reveal rapid disk formation

When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the light from these 'tidal disruption events' (TDEs) for clues to the feeding behavior of the supermassive black holes lurking at the centers of galaxies, and new observations help resolve crucial details of this process.
