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 research looks at neutron star blasts

X-ray bursts are highly energetic releases of radiation from the surfaces of neutron stars, triggered by the explosive burning of material accumulated on the surface. It's the same type of burning that happens in the cores of ordinary stars like the sun, but in this case, happening on the surface. Thus, unlike the sun, where it takes hundreds of thousands of years for this radiation to escape—and in a much weaker form—it happens almost instantly in an X-ray burst. This means that anything surrounding the neutron star is going to get blasted with radiation.
