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...

Astrobee's first robot completes initial hardware checks in space

NASA astronaut Anne McClain performs the first series of tests of an Astrobee robot, Bumble, during a hardware checkout. To her right is the docking station that was installed in the Kibo module on the International Space Station on Feb. 15. Bumble, and another robot named Honey, launched to the space station on Apr. 17, aboard Northrop Grumman's eleventh commercial resupply services mission from NASA's Wallops Flight Facility in Virginia. When needed the robots will be able to return to their docking station on their own and recharge their battery power.
