In the Northern Hemisphere during the spring, the bright star Regulus is easy to spot above the eastern horizon. The alpha star of the constellation Leo, Regulus is the spiky star centered in this telescopic field of view. Regulus is a hot, rapidly spinning star that is known to be part of a multiple star system.   CREDIT: Markus Horn Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent every weekday.

June will feature several opportunities to see Mars and the moon in close proximity to Regulus, the iconic blue star(s) that shine from the heart of Leo, along with two weeks’ worth of excellent opportunities for observing Mercury. And did you know that June 30 is International Asteroid Day? June 1– Crescent Moon Visible Between Mars and Regulus The first evening of June will find the crescent moon sitting squarely between Mars and Regulus, the brightest member of the constellation Leo. Interesting fact: while it looks like a single object, the blue “star” we see as Regulus isn’t just one star. It’s actually four. The largest and brightest, Regulus A, is significantly hotter than our sun and way, way brighter than our sun, and is believed to be in a binary orbit with a much smaller object. This object is most likely a white dwarf, but it has never been observed directly. The other two stars–Regulus B and C–are also dwarf stars, and are also locked in a binary orbit. Anyway, keep Regulus in mind, because we’ll be returning to it later in the month. June 11– Full Strawberry Moon This month, the moon will reach peak illumination in the early hours of June 11. If you’re on EDT, the full moon will be at 3:44 a.m. This month’s moon is called the Strawberry Moon, and of all the lovely names for the full moon, June’s might just be the prettiest. The name refers to the berries that ripen as the summer solstice approaches, not the color of the moon itself, which will remain resolutely silver. Several Native American languages use this term, including Ojibwe, Oneida, and the Mahican dialect of the Stockbridge-Munsee band of Wisconsin. Other languages have similarly poetic names: in the Catawba language it’s the “River Moon” and in Cherokee it’s “They Are Arriving/Plants in Garden are Sprouting Month”, while in Seneca and Tunica it’s simply the “Summer Moon.” Mid-June– Mercury Shows Off Our solar system’s innermost planet can be difficult to observe—it’s small, dim, and a lot of the time, it simply gets lost in the glare of the sun. However, this month marks one of the regular periods when Mercury appears far enough removed from the sun to be visible to the naked eye. Throughout June, Mercury will approach its maximum eastern elongation,the point at which it appears furthest east of the sun. Unfortunately, its magnitude—i.e. its apparent brightness—will decline over the course of the month, and by the time it hits maximum elongation in early July, it’ll be dim enough that you might struggle to spot it without the aid of a telescope or some binoculars. This means that mid-June will offer the best balance of elongation and magnitude. As per the ever indispensable Farmer’s Almanac, Mercury should be visible between 9:00 p.m. and 9:15 p.m. local time, low in the sky to the west-northwest. On June 26, it’ll peek out from slightly below and to the left of the crescent moon.  [ Related: Mercury stuns in incredibly detailed new images. ] June 16-18– The Red Planet Meets the Blue Heart of Leo So, another thing about Regulus: it sits close to the plane of the solar system, which means that it is often seen in close proximity to the moon and the planets. This month brings one such occasion: for the nights of June 16, 17, and 18, Regulus will appear right next to Mars. The proximity of the Red Planet and the blazing blue heart of the constellation Leo should make for a pretty spectacular celestial juxtaposition. June 20– The Summer Solstice In the Northern Hemisphere, June 20 is the day on which the sun is highest in the sky, aka the summer solstice! This is the day on which the North Pole is tilted most directly toward the sun, bringing 24-hour daylight to the Arctic Circle and the longest day of the year to the rest of the Northern Hemisphere. Summer is here, y’all! June 30– International Asteroid Day June 30 marks the anniversary of the Tunguska Event, a frankly terrifying asteroid strike that remains the largest asteroid impact event in recorded history. On June 30, 1908, an asteroid estimated to be  about 160 to 200 feet wide exploded several miles above the surface of a remote area of Siberia. The force of the detonation is estimated to be comparable to  between 3 and 50 megatons of TNT, and registered on seismographs around the world. For comparison, the atomic bombs dropped on Hiroshima and Nagasaki had yields of 0.015 and 0.021 megatons, respectively.) The resultant shockwave flattened an estimated 80 million trees over an area of 830 square miles and broke windows hundreds of miles away. In 2014, a group of scientists proposed that June 30 be designated International Asteroid Day. The UN adopted the idea two years later. The day recognizes the potentially calamitous effect of asteroid impacts—what might have happened had the Tunguska asteroid hit a city instead of a barren part of Siberia doesn’t really bear thinking about—and to raise awareness about the importance of asteroid-tracking endeavors. Anyway, hopefully June’s stargazing endeavors won’t reveal any terrifying asteroids hurtling toward us. Whatever you’re setting your sights on, though, you’ll get the best experience if you get away from any sources of light pollution—and you make sure to check out our stargazing tips before you head off into the darkness. Until next month!

We may earn a commission from links on this page.The only thing I didn’t love about the Mammotion Luba robot lawn mower I tested last summer was its size. It’s a hulking four-wheel-drive robot and I live in the city, where we don’t have huge lawns. Enter the Luba Mini, a halved version of the Luba meant for smaller lawns (and tighter budgets). In fact, if you paid attention this spring, miniaturized versions of some of my favorite technology were everywhere. These mini-me versions seem to be driven, according to the companies themselves, by two market needs. While smart home tech is incredible in terms of functionality and independence, it often comes at a steep cost. But it’s not just price driving the shrinking of our tech; many companies realized was that many folks wanted the automation even when they didn’t have an acre of lawn to mow or a wall of windows to clean. Here’s how a few of my favorite pieces of technology have shrunk themselves to become more accessible and affordable.Mini lawn mowers Yuka full size on the left and mini on the right Credit: Amanda Blum Mammotion released mini models of both the Luba (AWD) and Yuka (2WD) robot mowers, and I’ve been testing them for the last month. In terms of size, they’re perfect for most suburban and urban lawns under ¼ acre and have almost the same functionality as the larger models. That's the point, according to Senior Product Manager David Cheng, who told me, "We weren’t just shrinking our existing models—we were filling a real gap in the market for homeowners seeking smart, perimeter wire-free lawn care that fits smaller outdoor spaces."Mammotion’s mowers require an RTK tower, which is a highly accurate GPS method that allows for triangulation between the mower, the tower and satellites. Using your phone as a remote control, you walk the robot around the perimeter of your lawn to set up zones, and create pathways between zones so the robot can navigate on its own. The minis have a new benefit, which is the ability for them to map spaces on their own, without you walking them around. If your yard has clear borders, I found it worked as well as mapping the area on your own.   The larger Yuka comes with a hopper for grass clippings, which you can teach to dump the clippings anywhere you like—the mini doesn’t have that option. Still, I didn’t find the hopper very usable on the large version, so no loss there.  I did find the minis had trouble, regardless of which version of mapping you used, getting to some edges of the yard. If there were overhanging shrubs casting a long shadow, the AI would interpret that as a no-go zone, avoiding it altogether. Still, that was the only degradation of features I found between the models. The mini has another benefit: It’s a lot less conspicuous parked at the dock, given the size. While you can install a 4g chip in your robot and set up notifications in case someone grabs it and goes, you just know where someone has absconded with it to.  The models use the same app, and the minis mowed as well as the original models. At a dramatically lower price point, this gives you an excuse to invest in a robot mower if the thing holding you back was how large or expensive they are.

Through the fall, winter, and this spring, I have used it extensively because it turns smoking (a merciless task that involves a lot of overnight grill babysitting) into a flawless, hands-off experience. You tell the grill what you want to make, and AI kicks in to tell the grill how to make it, and it will notify you when it's time to flip things over or add a baste; when it's done, the grill turns itself off.You can, of course, edit the smoking program, create one on the fly, or just use the smoker manually as a grill. I went from someone who never rarely smoked on the grill to someone who does so once a week. On my recommendation, a BBQ devotee up the block added a Brisk It to their three-smoker lineup and revealed to me that it has become their favorite. Still, the original Brisk It clocks in just under $600 so I was excited to test the Zelos, a smaller, less expensive Brisk It with all the functionality of the Origin, albeit with less real estate. My experience isn't that unique, according to Christopher Huang, CEO at Brisk It. "Over 70% of U.S. adults say they want to cook more at home, but cite time and effort as their biggest barriers...and while more than half of home cooks express interest in smart kitchen tech, only 15% actually use it regularly." the mini has about 80% of the space of the original, seen here. I fit a whole rack of ribs plus a tray of chicken, but couldn't fit two racks of ribs. Credit: Amanda Blum Even as a highly enthusiastic home cook willing to put in the time, I cannot deny how much utility I get out of smart home automation in the kitchen. A smart grill is out of this world, since the notifications and temperature reporting of the grill and food means I don't have to stand over the grill. Brisk It even helps control the stall that barbecued meats often experience. Last month, I set up the Zelos (a thirty-minute affair) and invited neighbors over. I was worried about the smaller grill space (the Origin has 580 inches of grill space to the Zelos' 450 inches). While I could fit more racks of ribs on the Origin, the Zelos accommodated a full rack, plus a whole tray of chicken thighs, and I used the upper rack to smoke an array of vegetables. It didn't escape my attention that because the smaller grill uses less fuel (both are powered by pellets, although the control unit requires electricity), I'd be more likely to use it more often. Again, the app experience is the same on both models, and is highly functional and, dare I say, pretty fun. The AI the program uses is great for finding new recipes, a function I find underwhelming in practice on other products. At a reduced price, the Zelos makes an awfully appealing Father's Day gift, since it will also free up Dad from watching the grill all day.

The Winbot is about 13 inches square, and works by suctioning itself to your window and then putting it through a four-step wash process. I know people with Winbots, and if you have large square or rectangular windows, particularly those where some portion of the window is out of reach, it seems worthwhile. If you've got arched windows, though, the Winbot struggles with shapes that don't match the design of the robot itself, which has 90-degree angles. The Winbot also isn't for curved glass. These may seem like a lot of limitations, but I spent the winter in Arizona looking at a lot of glass patio doors, patio rooms, and walls of dusty windows and thought, "Ah...this is what the Winbot is for." Except now, there's a Winbot Mini, with an 8.5-inch square footprint. At that size, almost all my windows are fair game, so I'm excited to try it out. That was the point, according to Michelle Jones, U.S. spokesperson for ECOVACS, who said, "We saw an opportunity to bring the power of our larger window-cleaning robots to homeowners in the U.S. who have smaller or segmented window panes and don’t need a fixed cleaning station."But Ecovacs also points to a more specific problem that a lot of smart tech products suffer from, in my opinion: By the time the company has worked out the tech, the solution is often overly complicated. Ecovacs recognized that, as well, and simplified the offering in the Winbot Mini. The Mini ditches the rubber bumpers of the larger model, but that means better edge-to-edge cleaning. The mini also gains more portability by not having a heavy station like the full size model. What the mini lost seems like a worthwhile tradeoff for the price: The large Winbot has twice as many cleaning programs and more safety features (12 to the Mini's 9), but in both cases, what the Mini has seems sufficient. Priced around $250, the WinBot Mini feels like a luxurious piece of tech within reach for most folks.

A small, charegable device, the Shelfy uses a catalyst on a ceramic filter, activated by LED lights in the device to mimic chlorophyll photosynthesis. To simplify, it purifies the air in your fridge to remove ethylene gas that ripens vegetables, and it removes odors and prevents cross contamination.I can confirm that it works to make your fridge smell better, and while I can't confirm the additional twelve days of freshness in vegetables that Shelfy claims, it has definitely added some shelf life to my fruits and vegetables.In particular, I notice the change in fruit. I buy strawberries and blueberries with some regularity year round, so I know traditionally how long they'd last before starting to form mold (two to four days). As long as I have Shelfy charged, I can get a full week out of strawberries and ten days out of blueberries. That's a huge difference that creates savings in my food budget. The CEO of Shelfy, Paolo Ganis, put a number to the savings, explaining that "the average family throws away approximately $1,996 worth of food each year—money that could easily be saved with better food preservation." Vitesy Smart Refrigerator Device | Extends Food Freshness $149.99 at Walmart Learn More Learn More $149.99 at Walmart Shelfy isn't large or particularly expensive (it's just under $150) but Vitesy has just introduced a Kickstarter for the Shelfy Lite, which will only be $66 (the project is already funded). "Through a number of user surveys, we consistently heard that people loved the idea behind Shelfy but wanted a version that was more accessible: smaller, more affordable," Ganis said.The Lite adds multiple modes to the device, one for the general fridge, one for the crisper drawer and a power mode for when someone buys a particularly stinky cheese. The Lite improves on the battery charging and performance over the original model, and comes in some additional accent colors, if you care about that sort of thing. The Lite is only marginally smaller than the original Shelfy, but at less than half the price, that seems immaterial.What I've enjoyed about the Shelfy is that there are no filters to replace; you simply wash and wet the ceramic filter when you recharge the device every few weeks. If you don't recharge it, there are no annoying beeps or notifications—it's been a quiet helper.A smart home hub for lessSometimes even I forget there are smart home hubs outside of Samsung, Amazon, Apple, and Google. But Homey, a hub that keeps all your connections local, has gained traction over the last few years since its introduction. Homey has a specific focus on automation through its "Flow" platform, which is a version of routines or automatons in any other platform. Homey fans claim Flow has far more flexibility, and although I've never found Alexa or Google Home difficult, Homey is noted for its appeal to beginner smart home fans. Still, at just under $400, the Homey Pro hub was an expensive way to dive into smart home tech, compared to other platforms. Jasper Foppele, head of marketing at Homey, was transparent about their strategy, explaining that their usage data and feedback made clear they had to rethink their offering. Instead of trying to offer everything (the Homey Pro supports 60 apps), the Homey product team chose the core technology they saw being used in the U.S. market (Matter, Thread, Zigbee) and winnowed the app coverage to the most common 25. "This approach allowed us to significantly reduce cost and complexity," Foppele said, "a privacy-first, locally running smart home hub priced at $199."The Homey Pro Mini still prioritizes local first connection, including backups, but it has an option for cloud backup. The Mini is on pre-order and will ship sometime this month.

Everything is more expensive this year, and that likely includes utilities like your water bill. While growing vegetables in your yard can be enchanting and empowering, it isn’t very efficient (compared to farms) in terms of water usage. There are a number of ways to become more efficient and sustainable, including using drip irrigation, but another way is to only plant vegetables that don't need too much water to begin with. Watering at the root is keyBefore I get to the specific vegetables, it's important to go over a few general watering tips.Remember that vegetables get hydration through their roots, which live underground. Watering from above, like a hose or sprinkler, has problems: you’re getting the plants wet more than the roots, which creates conditions for disease spread; you’re watering less precisely, therefore wasting water; and the impact of the water against the dirt causes droplets to bounce back up with whatever fungus or viruses are in the dirt, also spreading disease. Watering gently and consistently at ground level with drip irrigation is the best option for both the plant and your wallet. To ensure you’re watering efficiently, group plants with similar watering needs together in your garden, so you can set the drip appropriately to water less. But even more important is remembering that roots grow over time. A new seedling has shallow roots, whereas an end-of-season plant has deeply established roots. More roots means that the plant can absorb more water from deeper underground. Less roots means less hydration from the soil, so more water is needed at a shallower depth. (Though some vegetables, like corn and lettuce, will always be shallow rooted, and thus aren’t good candidates for less water.)Hothouse plantsAccording to Oregon State University, a tomato plant's need for watering is negated by the deep roots the plants establish over the season. As above, you want to water sufficiently early in the season as roots are established while taking care not to over water, which will result in those roots staying close to the surface. If the plant needs water, those roots will grow deeper in search of moisture. Reducing water greatly, if not cutting it off entirely mid-season, shouldn’t harm your harvest. The lack of surface water will reduce disease spread, and tomatoes will ripen if you reduce their watering. It’s not only tomatoes, either: Squash, which includes zucchini, summer and winter squash, as well as melons, eggplants, and hot peppers all behave the same in terms of water needs and roots. Beans Credit: Amanda Blum Most beans, particularly pole beans, have adapted to drought conditions over time. As such, they can survive and produce flowers and fruit with minimal moisture. Beans require water to germinate, so if you direct sow, ensure the seeds have consistent moisture levels. Once germinated, you can reduce (but not eliminate) water. Since beans have such a short season (usually 60 days or less), they require less water simply by existing for less time. Less moisture is going to reduce common bean problems like powdery mildew, a quickly spreading surface fungus.Chard and okra Credit: Amanda Blum For some heat hardier vegetables like chard and okra, they still require water, but do better with weekly or every-other-weekly deep watering, as opposed to daily drip. Okra is native to drier climates and prefers less water. The deep roots of the plant allow it to draw enough water from the soil to sustain itself. Chard and kale can use their huge leaves to shade the ground, which is an effective form of moisture retention. Occasional deep waterings will be enough for the plant to continue growing.Blueberries prefer less moistureI know, blueberries are a fruit and not a vegetable, but I felt compelled to include the advice here anyway. Consider it a bonus tip. A few years ago, Micah Geiselman, a blueberry farmer from Morning Shade Farm in Canby came to inspect my many bushes, and he had surprising advice: “People over-water their blueberries,” he explained to me. They appreciate good drainage and do better with less water. I’ve since changed the elevation of my blueberries to ensure better drainage and moved watering lines further away—the results were astounding. I experienced better yields, but the berries themselves were plumper and better tasting. This isn’t conclusive, of course, since there are too many variables to account for, but I take the advice of a blueberry expert seriously.
