Meet Betelgeuse: A True Superstar

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!

Originally published on www.kpbs.org Several groups are formally pushing back on San Diego Gas & Electric’s request to raise customer rates by 8.6% in 2028, citing affordability concerns. Under the proposal , an average electric bill would jump about $14 over 2027 estimates, while a natural gas bill would rise about $8. Edward Lopez, executive director of the San Diego-based Utility Consumers’ Action Network, thinks that’s too high. He cited a California Public Utilities Commission report that found SDG&E’s average residential electric rates have already risen 98% over the last decade. “Coming on the heels of the ever-increasing requests, at some point, isn’t enough enough?” Lopez said. “We all feel the pain of these rates. They’re getting out of hand.” About 20% of SDG&E residential customers are at least a month behind on their power bills, according to same report. The Utility Consumers’ Action Network and several other ratepayer advocacy groups filed formal protests against SDG&E’s rate request with the California Public Utilities Commission on Monday. It’s part of a complicated four-year regulatory process, called a general rate case , to determine how much money the utility can collect from customers starting in 2028. Now, organizations “intervening” in the regulatory proceedings on behalf of SDG&E customers are hiring experts to dig into the utility’s thousands of pages of application materials in order to answer some top-line questions. “What is the utility doing? What are they proposing to do more of? Is it reasonable? What are the costs associated with that? Are those costs reasonable?” Lopez said. SDG&E wants to collect about $3.8 billion from customers in 2028, a roughly 8% bump over next year’s estimated revenue requirement. The utility says inflation, rising medical benefit costs and wildfire-related expenses are driving the increase. For SDG&E and other privately-owned utilities in California, shareholder revenue is partially based on the return from infrastructure projects. Malinda Dickenson, executive director of the San Diego-based Protect our Communities Foundation, contends SDG&E could lower its requested rates by prioritizing local power generation. The foundation’s protest filing calls for greater consideration of small-scale solar generation and storage in order to reduce costs tied to hardening grid infrastructure against wildfire risk. “You're not going to need these transmission upgrades and new transmission lines to bring power from faraway places to urban centers where the power’s used,” Dickenson said. “So what Protect our Communities will be doing in this proceeding is presenting alternatives to SDG&E’s heavy capital expenditures.” SDG&E has until July 30 to respond to intervening groups’ protests. In a statement, the utility acknowledged affordability is top of mind for customers. “Our proposal reflects a focused, disciplined plan to keep energy safe and reliable while managing costs responsibly on behalf of the customers and communities we serve,” spokesperson Anthony Wagner said. “We support the transparent regulatory process that allows customers, community members and other stakeholders to provide input as the [California Public Utilities Commission] reviews our request.” The commission’s five voting members will ultimately decide whether to grant or adjust SDGE’s rate request.

By Dennis Mammana Week of July 26 - Aug. 1, 2026 In a couple of weeks, I'll be telling you about the annual Perseid meteor shower. It should be a good one this year since moonlight won't reduce our view. Of course, if you've read my column regularly, you already know that stargazers will almost always see more meteors in the hours before dawn than during the evening, so that means we must rise early or stay awake all night. I know either can be quite a challenge for some, so this week I present to you an opportunity to practice getting up early and heading outdoors. Not for meteors — though you will almost certainly spot some early Perseids in the early morning sky — but to see two planets that haven't been visible during the evening hours for quite a while. During early dawn this week, early risers have the chance to see the only two planets of our solar system whose names begin with the letter M: Mars and Mercury. Before sunrise, look midway up in the eastern sky, and you'll spot a fairly bright reddish-orange light. Many people may think that's the Red Planet, but I assure you it's not. It's actually a star named Aldebaran, and it marks the fiery red eye of Taurus, the bull. Betelgeuse, in Orion, the hunter, also appears the same color. It's true that Mars also appears reddish-orange, but at this time, it appears 1.5 times fainter than Aldebaran and can be found to its lower left. Because it's so faint, you may have a tough time seeing its color easily, but aim binoculars or a small telescope in its direction and its ruddy hue will become quite apparent. Mars changes its distance from Earth, and therefore its brightness, quite dramatically over its orbit around the sun. It can go from about 35 million miles from us at its best oppositions; the next of these won't occur until September of 2035, when it will lie just 35.8 million miles from us. That will be a great time to view the planet with a small telescope, but right now, Mars lies nearly 186 million miles from us and appears quite small and faint. The other planet visible in the early morning hours this week is the elusive planet Mercury. I use the word elusive because this planet is the closest to the sun of all our solar system's worlds and, as such, never strays far from its glare. With its orbital motion combined with that of the Earth, Mercury flips from dusk to dawn about every three or four months, but it's always rather tough to spot. It's been said that the great 16th-century Polish astronomer Nicolaus Copernicus, who overturned the long-held notion that the Earth occupied the center of our planetary family, had never actually seen this world with his own eyes. Now I don't know if this is true, but it makes sense given what we know about weather conditions in Eastern Europe and how challenging Mercury is to spot. This week you can achieve something even the great Copernicus never could ... but you've got to get up pretty early to do it! Visit Dennis Mammana at dennismammana.com.

By Karen Pearlman, East County Magazine July 20, 2026 (Ramona) — San Diego County’s aerial firefighting capabilities have been boosted with the reopening of the modernized Ramona Air Attack Base, where state and local officials on Monday morning unveiled nearly $20 million in upgrades designed to get aircraft back into the air faster and expand around-the-clock wildfire response. The renovated base at 2498 Montecito Road now houses a new 4,000-gallon CAL FIRE C-130 Hercules air tanker, a night-capable S-70 CAL FIRE Hawk Helicopter, two S-2 air tankers and an OV-10 Air Tactical aircraft. The group of aircraft is creating what officials called one of California’s most advanced aerial firefighting hubs. The base’s aging infrastructure has been replaced with a modern retardant mixing plant capable of storing 20,000 gallons of fire retardant, redesigned aircraft loading bays that dramatically reduce turnaround times, and expanded ramp space to accommodate additional air tankers during major wildfire incidents. “This base is a regional asset,” CAL FIRE/San Diego County Fire Chief Tony Mecham said at a press conference that was livestreamed on YouTube . “When there is smoke in the sky, the citizens don’t care what color the fire engine is or what patch is on the uniform. They just want people to show up quickly.” The improvements come as California faces increasingly destructive wildfire seasons fueled by hotter temperatures, prolonged drought and more extreme weather conditions. CAL FIRE Director and Fire Chief Joe Tyler said the Ramona facility reflects years of investment in modernizing California’s aerial firefighting fleet. Over the past two years, CAL FIRE aircraft have flown more than 11,500 flight hours annually while maintenance crews logged more than 90,000 hours keeping aircraft mission-ready, Tyler said. Among the most significant additions is the C-130 Hercules air tanker, capable of dropping 4,000 gallons of fire retardant — more than three times the capacity of CAL FIRE’s traditional S-2 air tankers. The aircraft is part of the state’s new fleet of converted military transport planes that entered service beginning in 2024. Also based in Ramona is the county’s new S-70 Firehawk helicopter, which can perform water drops after dark — a capability officials said is already proving invaluable. It has an integrated 1,000-gallon water tank with hoist rescue capability and the ability to transport helicopter crews into remote terrain. San Diego County Board of Supervisors Chair Terra Lawson-Remer pointed to last week’s Thorn Fire, where the Firehawk flew nighttime suppression missions that slowed the fire’s progression and helped prevent flare-ups the following morning. “Our days are getting hotter, our nights are getting warmer, the winds are stronger and fuels are drier,” Lawson-Remer said. “Wildfire does not stop when the sun goes down.” She urged residents to prepare for wildfire emergencies by signing up for emergency alerts, planning evacuation routes and heeding evacuation orders when issued. For East County backcountry communities, the upgrades could mean quicker aerial response to fires threatening homes. Aircraft assigned to Ramona regularly respond throughout the county. Mecham twice shared the importance of coordinated and consolidated efforts between firefighting agencies across the county. “We fight fire without boundaries and without egos,” he said. Mecham said the modernization project focused on improving efficiency as much as expanding capabilities. Previously, air tankers were forced to maneuver awkwardly into a single retardant loading area, creating backups during major wildfire incidents. The redesigned facility features three drive-through loading pits that allow aircraft to taxi in, reload and immediately return to the fire. “The S-2s can reload in about two to three minutes,” Mecham said. “The C-130, under 10 minutes, it’s on the ground here at Ramona before it’s back in the sky responding to the next fire.” The expanded ramp now allows up to six air tankers to stage simultaneously. During last week’s Thorn Fire, officials said 11 air tankers were assigned to the incident, underscoring the need for increased loading capacity. Additional improvements are in the planning stages. Construction is expected to begin next year on a 14-person barracks to support future 24-hour operations, along with further expansion of the helicopter facilities. Monday’s ceremony also highlighted the historical significance of the Ramona Air Attack Base, which opened in 1957 as CAL FIRE’s first aviation base. While the facility received new buildings in 2000, much of its underground infrastructure — including water lines, electrical systems and retardant delivery equipment — had remained unchanged until the recent reconstruction. San Diego County Supervisor Joel Anderson, who lives in the fire-prone area of Alpine, thanked leaders for their understanding of the importance of the Ramona airport site… “not just in San Diego County but for Southern California in general.” “CAL FIRE has been an essential partner for the County Fire, providing joint fire protection in emergency services for more than 1.7 million acres,” Anderson said. “Since CAL FIRE’s creation in 2008, the Board of Supervisors have invested over a billion dollars into fire protection in emergency medical services. “In the years since we created County Fire, we have also expanded our partnership in collaborations. In 2022, CAL FIRE successfully collaborated with the Ramona Municipal Water District to establish the Ramona Airport as a hub for aerial firefighting teams, in addition to replacing fire engines and adding a third ambulance, which was so important to the backcountry and to all my constituents.”
