Aurora Borealis Visible in Borrego Springs

By Dennis Mammana Week of March 22-28, 2026 Now that spring has sprung, I'm sure that those who have endured a long, cold and snowy winter are rejoicing. Anyone who knows me knows that I'm no winter person. Sure, I used to enjoy the season when I was a kid, but that's only because I could spend entire days building snow forts with my friends and making a few bucks shoveling the white stuff for neighbors. No longer. Today, warmer days of springtime can't come soon enough for me! If we had no calendar, we would still know the seasons are changing. We see it happening all around us: Temperatures are rising, the first flower buds are beginning to appear, and many birds are returning to our part of planet Earth. And, just as our daytime world gives us clues that spring is approaching, the darkness does as well. Nighttime hours are beginning to shorten, and the brilliant stars of winter are descending in the west to make way for those of springtime. And no star grouping heralds the arrival of springtime to our Northern Hemisphere more than Leo, the lion. Head outdoors during early evening hours and cast your gaze midway up in the eastern sky. There, you'll see Leo, one of the few constellations that, with some imagination, actually can be made to look like its namesake — a lion crouching in a regal pose reminiscent of the enigmatic Egyptian Sphinx. Most prominent in this constellation is the bright star Regulus, which shines brightly beneath the lion's majestic head and mane, outlined by a large sickle-shaped grouping of stars. More metropolitan stargazers may recognize this figure not as a sickle but as a backward question mark, with Regulus forming the dot at its base. The star's very name, "Regulus," comes from the Latin word "Rex," meaning "king," and, interestingly, this star was revered throughout the ancient world as a "royal" star. According to astronomy author R.A. Allen, it was known in Arabia as "Malikiyy" (the Kingly One), while the ancient Greeks knew it as "the Star of the King." At the other end of the lion, we find the bright star Denebola, whose name originates from the Arabic "Al Dhanab al Asad," meaning "The Lion's Tail." You can find Leo more easily if you use the two pointer stars of the Big Dipper, farther to the northeast. These stars point toward Polaris (the north star) if you follow them from the bottom to the top of the Dipper's bowl, but if you follow them in the opposite direction, you can find your way toward the back of the lion. If you have trouble tracing this animal's shape among the stars, don't worry. Just turn it around and you'll find it's much easier to find not the mighty king of the jungle but instead a mouse! Quite frankly, I think the figure of a mouse is much easier to trace. Here, the star Denebola forms its pointy nose, the nearby triangle forms his head, and the sickle now outlines its long, curving tail. Either way you look at it — mouse or lion — nothing in the heavens announces springtime more loudly than Leo!  Visit Dennis Mammana at dennismammana.com.

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.
