ABDNHA 2025-26 Activity Calendar is Out!

By Dennis Mammana Week of March 8-14, 2026 If you hear the word "superstar," what immediately comes to mind? Perhaps names like Tom Hanks, Taylor Swift or LeBron James? That's certainly understandable; they are all undisputed superstars who attract the attention of paparazzi and fans alike. If you're an astronomer, however, you may answer this question differently. For example, when I hear the word "superstar," I think of UY Scuti, WOH G64 or RSGC1-F01. Yes, these are superstars, but not quite how people may think. These are some of the largest stars known in our galaxy and, for that reason, are quite intriguing to us celestial paparazzi. Regular readers of this column know that our sun is also a star. It appears big and bright in our daytime sky because not only is it rather close (about 93 million miles away), it's also pretty large (nearly a million miles across). It sounds huge, but our star is rather small on a cosmic scale, and believe it or not, there are stars out there that would dwarf our sun and make it look tiny. These are the true superstars! Until recently, the largest star known was given the hopelessly poetic name of UY Scuti. At a distance of some 9,500 lightyears from Earth, UY Scuti is what is known as a red hypergiant star, with a diameter some 1,700 times that of the sun! All that changed recently, however, when astronomers found a gargantuan star some 2,150 times larger than our sun! It's named Stephenson 2-18, and if you'd like to get a peek at this stellar behemoth, you'll need more than your eyes. At a distance of some 18,900 lightyears, it appears 5,100 times fainter than we can see without a telescope. If you have no telescope but would still like to see a celestial superstar, you're in luck. There's one shining in our night sky right now; it's one of the brightest up there and is named Betelgeuse. Betelgeuse sparkles brightly in the northeastern corner of Orion, the hunter, and you can see its orange light midway up in the southern sky after dark this week. With about 15-20 times more mass than our sun, Betelgeuse is known as a red supergiant star for good reason. While we could align 109 Earths across the face of our sun, we would need at least 700 suns to cross the face of Betelgeuse! Indeed, this star is so immense that if it replaced our sun at the center of our planetary system, Betelgeuse would engulf the orbits of Mercury, Venus, Earth and Mars, and stretch part of the way to Jupiter! Yet it appears as a simple point of light in our night sky because of its tremendous distance from us — some 3,100 trillion miles, or about 520 lightyears. Betelgeuse is easily one of the largest known stars, though its size fluctuates by as much as 60% as the star shudders and pulsates on its way to an eventual supernova explosion, thousands or millions of years from now. Or tonight. We just don't know.  I hope you'll step out under the night sky soon to meet this remarkable superstar for yourself! Visit Dennis Mammana at dennismammana.com.
