Sign Up for Free Livestreams from Space Telescopes Just in Time for the Solar Eclipse

Don’t have plans to watch the upcoming solar eclipse in person? As long as you have an internet connection, you’ll be able to watch it live from home by signing up for the celestial event streaming service Slooh.

As The Verge reports, Slooh provides livestreams of full moons, comets, and even exploding galaxies, observed through its seven telescopes on the Canary Islands and three more in Chile, for what’s normally a monthly membership fee of $4.95. It also periodically provides free streams of celestial events like meteor showers, planets in opposition, and the occasional super beaver moon.

But starting August 7, Slooh will waive the cost of its basic services. All you have to do is register with the website. Registration includes up to 20 hours a day of prime space views. In the coming weeks viewers will be able to witness the Perseids meteor shower, Cassini’s descent into Saturn, and of course the North American solar eclipse on August 21.

Members willing to pay $4.95 a month to become a Slooh Apprentice will have the power to reserve short periods of time on its telescopes five times a month and point them at different parts of the sky. There's also the Slooh Astronomer package at $24.95 a month which includes unlimited telescope reservations. But whether you're an Apprentice, an Astronomer, or just a casual stargazer, the service is an affordable replacement for a high-powered telescope of your own.

Eclipses Belong to Families That Span Millennia

If you’re lucky enough to see the solar eclipse when it passes over America on August 21, you’ll bear witness to a centuries-long legacy. That’s because total eclipses of the sun aren’t isolated incidents that occur at random. They belong to interconnected eclipse families that humans have been using to track the phenomena since long before the first telescope was invented.

In the latest installment of StarTalk on Mashable, Neil deGrasse Tyson chats with meteorologist Joe Rao about the science behind eclipse families. According to Rao, eclipses follow Saros cycles which repeat every 18 years, 11 days, 8 hours. Astronomers keep track of many different Saros cycles. The eclipse on August 21, for example, is a member of the family Solar Saros 145. Every 18 years a Saros 145 eclipse falls over a different third of the Earth. In 1999, the great American eclipse’s “cousin” appeared in the skies over Europe and south Asia, and 18 years before that another relative could be seen over modern Russia. The Solar Saros clan can be traced all the way back to 1639 and it will keep going until 3009.

Today, scientists have space-age technology that allows them to track the moment of totality down to a fraction of a second. But thousands of years ago, before such satellite-tracking equipment was invented, ancient Babylonians only knew what they could observe from Earth. Their eclipse calculations ended up serving them pretty well: They were able to predict the same 18-year cycle we know to be true today.

Saros 145 isn’t the only family of eclipses making its way around the Earth. There are enough solar eclipse cycles to make the event a fairly common occurrence. If you’re curious to see how many will happen in your lifetime, here’s where you can calculate the number.

‘Total Eclipse of the Heart’ Could Have Been a Meat Loaf Song

Imagine a world in which Bonnie Tyler was not the star performer on the Royal Caribbean Total Eclipse Cruise. Imagine if, instead, as the moon crossed in front of the sun in the path of totality on August 21, 2017, the performer belting out the 1983 hit for cruise ship stargazers was Meat Loaf?

It could have been. Because yes, as Atlas Obscura informs us, the song was originally written for the bestselling rocker (and actor) of Bat Out of Hell fame, not the husky-voiced Welsh singer. Meat Loaf had worked on his 1977 record Bat Out of Hell with Jim Steinman, the composer and producer who would go on to work with the likes of Celine Dion and Barbra Streisand (oddly enough, he also composed Hulk Hogan’s theme song on an album released by the WWE). “Total Eclipse of the Heart” was meant for Meat Loaf’s follow-up album to Bat Out of Hell.

But Meat Loaf’s fruitful collaboration with Steinman was about to end. In the wake of his bestselling record, the artist was going through a rough patch, mentally, financially, and in terms of his singing ability. And the composer wasn’t about to stick around. As Steinman would tell CD Review magazine in 1989 (an article he has since posted on his personal website), "Basically I only stopped working with him because he lost his voice as far as I was concerned. It was his voice I was friends with really.” Harsh, Jim, harsh.

Steinman began working with Bonnie Tyler in 1982, and in 1983, she released her fifth album, Faster Than the Speed of Night, including “Total Eclipse of the Heart.” It sold 6 million copies.

Tyler and Steinman both dispute that the song was written specifically for Meat Loaf. “Meat Loaf was apparently very annoyed that Jim gave that to me,” she told The Irish Times in 2014. “But Jim said he didn’t write it for Meat Loaf, that he only finished it after meeting me.”

There isn’t a whole lot of bad blood between the two singers, though. In 1989, they released a joint compilation album: Heaven and Hell.
