If you've grown tired of Zoom meetings, Netflix parties, and livestreams, take a break from staring at your screens to look up at the sky. Starting in April, the Lyrid meteor shower will make its annual appearance. Here's what you need to know to see the spectacle from wherever you're quarantined.

What are the Lyrids?

With written evidence of the event dating back to , the Lyrids are one of the oldest meteor showers on record. The light show occurs when our planet passes through the tail of the comet , causing its to burn up in the atmosphere.

From Earth, the Lyrids appear to originate from the constellation Lyra, which rises above the northeastern horizon after dusk, and the meteor shower borrows its name from the constellation. The Lyrids aren't as active as some other annual showers, usually maxing out at just 20 shooting stars per hour on peak nights. But patient spectators are sometimes rewarded: The event has been known to have outbursts of up to 100 meteors in a single hour. Such surges are rare and random, so all sky-gazers can do is look up at peak times and hope to get lucky.

How to See the Lyrid Meteor Shower

The Lyrids start every year around April 16, but your best chance at seeing them comes later in the month. Late April 21 through early April 22, the meteor shower is predicted to reach peak activity. Following that period, the shooting stars from the shower will become less frequent before finally fizzling out around April 25.

The Lyrids may be easier to spot in 2020 than in recent years. Since businesses closed and people started sheltering in their homes, there has been a slight dip in . Those darker, clearer skies will create better conditions for spotting shooting stars in some parts of the country. As always, waiting until skies are darkest—in the hours around midnight, typically—is the best way to boost your chances of seeing as many meteors as possible.

Even if you’ve heard that money or career success won’t necessarily make you happier, it’s still hard to resist the impulse to correlate your own well-being to external factors like those. Why are we so bad at predicting what will make us happy, and how can we figure out what actually does the trick?

美女视频黄频大全视频These are just a couple questions you’ll be able to answer after completing “The Science of Well-Being,” a Yale University course currently being offered for on Coursera. According to , the 10-week course consists of about two to three hours of reading and videos per week, and you can work at your own pace—so you can definitely take advantage of a free weekend to fly through a few weeks’ worth of material at a time, or postpone a lesson if you’re swamped with other work.

The class is taught by Yale psychology professor Laurie Santos, who will lead students through relevant research on how we’re wired to think about our own well-being and teach you how to implement that knowledge to increase happiness in your life. Since the coursework is task-oriented and the course itself is aimed at helping you build more productive habits, it’s an especially good opportunity for anyone who feels a little overwhelmed at how vague a goal to “be happier” can seem.

美女视频黄频大全视频As for proof that this is definitely an undertaking worth 20 hours of your time, we’ll let the previous students speak for themselves: From 3731 ratings, the course averages 4.9 out of 5 stars.

Though the course is free, an official certificate to mark your completion—which you can then add to your LinkedIn profile—will cost you $50. Enroll on the Coursera , and check out 23 other science-backed ways to feel happier here.

During this event, Venus is nine times brighter than Jupiter and 20 times brighter than —the brightest true star in the night sky. The only celestial objects that outshine Venus are the sun and the moon. Venus also has its atmosphere to thank for its high visibility. The planet is surrounded by a reflective,  made of sulfuric acid. An object's reflectivity level is called its bond albedo, and Venus has a bond albedo of .77, . In comparison, the moon's is .
