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...

Analyze this: Space station facility enables rapid biomedical analysis

In its role as a unique orbiting laboratory, the International Space Station provides a broad range of equipment for conducting health and life sciences research. However, the equipment available for cellular and molecular biology is limited compared to capabilities found in laboratories on Earth. To address this limitation, the Canadian Space Agency (CSA) commissioned an innovative biomedical device for an upcoming space station expedition. The videogame console-sized Bio-Analyzer enables near real time, onboard analysis using freshly collected biological samples such as blood, urine, saliva, sweat, and cell cultures.
