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.

By Dennis Mammana Week of March 1-7, 2026 Attention, night owls and insomniacs! The sky show this week is just for you! Much of North America is about to see the moon experience one of nature's most beautiful sky shows: a total lunar eclipse. A lunar eclipse occurs when the full moon slips into the Earth's shadow far out in space, either partially or completely, and that's just what will happen during the wee hours of March 3. Skywatchers throughout North America will see the start of this eclipse (weather permitting, of course), but depending on where you live, you may see only a portion of the sky show. In general, the farther west you live, the more of the eclipse you will see before the moon sets behind the western horizon. The eclipse begins at 12:44 a.m. PST (3:44 a.m. EST), when the moon enters the Earth's light outer shadow (known as the penumbra), but this shadow is so thin that no one will notice a darkening of the moon's appearance. Within an hour or so, that will change significantly. As the moon approaches the dark inner shadow of the Earth (known as the umbra), skywatchers will notice the eastern side of the moon beginning to darken slightly. The real show begins at 1:50 a.m. PST (4:50 a.m. EST) when the moon officially enters the umbra. No one gazing skyward will have any doubt that a "bite" has been taken out of the moon — a bite that will grow larger with each passing minute. For the next hour or so, the moon will dim as it slips more deeply into our planet's umbra, until 3:04 a.m. PST (6:04 a.m. EST) when it's completely engulfed and the total eclipse begins. Unfortunately, those in the far eastern part of North America may miss this since the moon will lie quite close to (or even below) the western horizon. During the total phase, the moon will take on a dim coppery hue. This occurs because sunlight passing through our atmosphere is reddened and bent inward toward the darkened surface of the eclipsed moon, now suspended eerily against the stars of Leo, the lion. Only those viewing from the Midwest to the West Coast will see mid-eclipse, which occurs at 3:33 a.m. PST (5:33 a.m. CST). Those in the Midwest may miss the end of totality at 4:02 a.m. PST (6:02 a.m. CST), however, as the moon will be setting in the west. The entire event will end at 5:17 a.m. PST (4:17 a.m. MST) with the moon approaching the western horizon for viewers in western North America. Unlike an eclipse of the sun, a lunar eclipse is perfectly safe to view without protective filters. Your eyes are all you need to enjoy the show, but you'll have even more fun viewing through binoculars or a small telescope. If the sky is cloudy that morning, or if you live where the eclipse won't be visible, you can watch a livestream of the sky show online. Visit timeanddate.com and click on "Sun, Moon & Space" at the top to find details for your location, as well as links to view the eclipse live online. Visit Dennis Mammana at dennismammana.com.

One Course, Many Possibilities Rams Hill Golf Club in Borrego Springs, California , remains one of Southern California’s most reliable golf destinations—offering a championship-caliber experience in a setting that adapts easily to different types of getaways. Whether you're planning a golf-focused weekend or a slower-paced retreat with friends or family, Rams Hill provides the foundation.  It’s not uncommon for guests to return to the same rental, play the same number of rounds, and dine at the same favorite restaurant—yet walk away with a completely different experience. Golf Designed for Everyone Designed by Tom Fazio , Rams Hill’s 18-hole course features dramatic elevation changes, wide landing areas, and expansive views across the Anza-Borrego desert. Multiple tee options suit a wide range of players, from scratch golfers to those still learning the game. Small but memorable touches—like tacos at the turn and post-round cookies—round out the experience. Paired with Stay & Play homes like The Desert Escape, guests can enjoy the convenience of staying on site while having space to relax, cook, or host small gatherings between rounds. Repeat Stays, Fresh Experiences One trip may focus on competitive rounds with fellow golfers. Another might center around a mixed group, some playing full rounds, others enjoying shorter outings or relaxing at the rental. The shared element is consistency: excellent course conditions, helpful staff, and the option to shape your schedule any way you like. Even repeat visitors report that the experience shifts depending on the group, the season, and how the trip is planned—without sacrificing the sense of quality or hospitality Rams Hill is known for. Summer in Borrego: More Than Golf While winter and spring are peak golf seasons, summer in Borrego Springs offers a quieter experience with wide-open skies, minimal traffic, and more room to explore beyond the course. For those interested in art, photography, or stargazing , the summer months offer clear air, high contrast light, and dramatic desert color. Visitors often combine their golf plans with stops at the Borrego Art Institute , which hosts rotating exhibitions and operates a garden-focused ArtPark nearby. Just a few minutes away, The Gallery at The Palms presents contemporary shows in a mid-century modern setting surrounded by native landscaping. These creative spaces offer a thoughtful balance to a golf itinerary and allow non-golfers to enjoy the weekend just as much. Dining in Borrego Springs Borrego Springs also offers a variety of local dining options , from casual cafes to full-service restaurants. Onsite, Rams Hill Restaurant is open to the public and known for elevated fare with sunset views over the course. In town, diners will find locally owned spots offering everything from breakfast staples to seasonal specials—many of which are open year-round. Easy to Reach, Hard to Forget Just under a two-hour drive from San Diego , Rams Hill is a short trip that feels far removed. Guests often return to familiar settings—the same house, same course, even the same server—and still leave with a new favorite moment.
