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...

NASA's Mars perseverance rover gets its sample handling system

With the launch period for NASA's Mars Perseverance rover opening in a little less than four months, the six-wheeler is reaching significant pre-launch milestones almost daily at the Kennedy Space Center in Cape Canaveral, Florida. The rover had some components removed prior to being shipped from NASA's Jet Propulsion Laboratory in Southern California to the Cape in early February. Last week, Perseverance's assembly, test and launch operations team integrated two components that will play key roles in the acquisition, containment and eventual return to Earth of humanity's first samples from another planet: the Adaptive Caching Assembly and the Bit Carousel.
