Look Up Tonight! The Lyrids Meteor Shower Is Set to Stun!

Look up tonight and you’ll see a waning crescent Moon, and, every few minutes, shooting stars falling from the sky. The Lyrids meteor shower peaks on April 21, and if light pollution is low in your area, you can expect to see around 10 meteors per hour—maybe more if you escape to the countryside.

WHAT IS GOING ON UP THERE?

The Lyrids—named for the constellation Lyra from which they seem to originate—are the happy result of the Earth slamming into the debris of the comet C/1861 G1 Thatcher (named after its discoverer, not the former British prime minister). But don’t worry: Thatcher isn’t a danger! As it flies about its four-century-long orbit around the Sun, particles fall away. It’s perfectly normal shedding, resulting in an annual evening-time spectacular.

Thatcher is a long-period comet; such comets have orbits longer than 200 years. At aphelion—that is, its farthest point from the Sun—Thatcher is at a distance of 110 astronomical units (AU). To put this in perspective, the distance from the Sun to the Earth is 1 AU. The distance from the Sun to Pluto is about 40 AU. The very farthest-known natural, observable object in the solar system, V774104, is presently 103 AU. So Thatcher has put in a lot of work to make tonight's light show happen. I hope you appreciate it. This meteor shower is 415 years and 21,225,138,770 miles in the making. If that’s not good enough for you, nothing is.

HOW DO I SEE THE LYRIDS?

Sometimes, the Lyrids deliver a mind-blowing show. Its first reported occurrence was reportedly so bright and busy that it drowned out the stars. In 1982, it reached 90 meteors an hour. Ordinarily, however, the meteor shower produces five to 20 meteors every hour. Don’t miss this chance to see them, because when it comes to dust-sized cometary particles vaporizing in Earth’s atmosphere at 30,000 miles per hour, you just never know how good the show will be.

The best time to see the Lyrids will be after midnight until just before dawn. While you wait, check out Jupiter, bright and unblinking in the south. If you have a telescope handy, or even a reasonably powered set of binoculars, you’ll easily see four of its moons: Europa, Ganymede, Io, and Callisto. You can also see Saturn to the southeast (though this isn’t the best time for viewing it). As dawn approaches, look east and you’ll see Venus up there, as bright as ever. (It reaches greatest brilliancy on April 30.)

To enjoy the Lyrids meteor shower, you won’t need binoculars or a telescope or anything, really, but a blanket and patience. Since it’s a Friday night, bring a bottle of wine. You’re not going to live forever. Because the Moon will be but a sliver, it won’t wash out the sky with moonlight. So Thatcher and the Moon are doing the heavy lifting here. All you have to do is show up and wait.

Ig Nobel Prizes Honor Self-Colonoscopies and Kidney Stone-Dislodging Roller Coasters

Not all science awards are reserved for discoveries that revolutionize their fields. As the Ig Nobel Prize recognizes, sometimes a largely pointless, but wildly creative, study is just as worthy of accolades. On September 13, the Ig Nobel Prize continued its tradition of honoring achievements "that make people laugh, and then think" with its 28th annual ceremony.

The Ig Nobel Prize recognizes work across a variety of fields. This year, the medicine prize was awarded to Marc Mitchell and David Wartinger for their investigation of whether or not riding a roller coaster can dislodge a kidney stone. The answer: It can, at least if you're riding in the back car of the Big Thunder Mountain coaster at Walt Disney World. Other notable winners include a study detailing a self-administered colonoscopy and one that asks if using a voodoo doll of your boss is an effective way to manage workplace aggression (it is).

Drones Rearrange This Canopy Prototype So You're Always in the Shade

When they're not rebuilding the environment or exploring Mars, the drones of the future may help us avoid some of life's minor inconveniences. A group of masters students at the University of Stuttgart envisioned a fleet of drones that does just that for their thesis project: As New Atlas reports, the drones are part of a roaming canopy, responding to sunlight above and movement below to ensure you're always in the shade.

Without the drones, the prototype, dubbed Cyber Physical Macro Material, resembles a normal stationary structure. Tall black poles support panels that fit together magnetically, protecting whoever's beneath them from the sun's rays. But this design is only effective when the sun is in a certain part of the sky: As the day progresses, the canopy's shadow shifts, and people are forced to move with it if they want to stay out of the light.

But these panels don't stay in the same spot for long. They come equipped with special sensors that keep track of the orientation of the sun and a communications system that corresponds with autonomous drones nearby. If a panel is no longer keeping the ground beneath it shady, a drone will glide over, lift it up, and snap it into a different part of the canopy like a puzzle piece. Drones can also rearrange the panels in response to the size and location of the crowd beneath them, which means the same structure that shades a few pedestrians can also keep a larger party cool.

There are legal and logistical hurdles the project would need to overcome before becoming a system in a real-world, but the researchers behind it say that for now it's meant to get people thinking about the potential applications for drones. A press release from the university reads, "With its ability to continuously reconstruct during use, the system challenges pre-conceived ideas of robotic digital fabrication and sophisticated pre-fabrication for architecture."

You can see how the drone-powered canopy works in the video below.
