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...

eROSITA delivers first striking images

Astronomers are excited: The first images by the eROSITA telescope launched in July reveal an impressive performance. After an extended commissioning phase, all seven X-ray telescope modules with their custom-designed CCD cameras have been observing the sky simultaneously since 13 October. The first composite images show our neighboring galaxy, the Large Magellanic Cloud, and two interacting clusters of galaxies at a distance of about 800 million light years in remarkable detail.
