You Could Be One of the First People to See the Upcoming Solar Eclipse With New Airbnb Contest

Airbnb
Airbnb

Airbnb is going to help two lucky people become some of the first in the nation to see the cross-continental total solar eclipse when it journeys across the U.S. on August 21. As Travel + Leisure reports, the company is holding a contest to send two guests on a deluxe eclipse-viewing mini-vacation in Oregon.

First, the winner and their guest will head to Bend, Oregon on August 20 to stay in a geodesic dome under the stars, looking up at the night sky from the observation deck with multiple telescopes, according to the press release. They’ll hang out and chat about the stars with with astrophysicist Jedidah Isler, who studies black holes, and learn how to shoot great nighttime photos with Babak Tafreshi, a National Geographic photographer.

The next day, Isler will accompany the winners on a private jet for a two-hour flight over the Pacific Ocean. The plane will fly along the path of totality, potentially extending the amount of time the guests have to view the Moon completely covering the Sun by up to a minute compared to what people will see from the ground.

Even if you don’t win, plenty of people are trekking out to the path of totality, and you can probably find another place to crash. Airbnb estimates that it has around 3800 listed houses along the path of totality. (This one in Oregon is going for $10,000 a night that weekend.) But you might have more trouble finding a private plane to fly you to a viewing spot atop the clouds. The next total solar eclipse won't be visible from the U.S. until 2024, so this is your last chance for a while.

You have until August 10 to send Airbnb your best argument for why you should get to go on a great eclipse adventure.

Why Do Astronauts Use Space Pens Instead of Pencils?

by Alex Carter

It's often said that NASA spent millions of dollars developing a pen that could write in zero gravity, while the Russians just used pencils. It was a warning about looking for a high-tech solution to a mundane problem, of American excess vs. Russian sensibility.

It's also entirely false.

To understand why NASA was so keen on a workable space pen, you have to understand that the pencil is not suited for space travel. The problem is that they have a habit of breaking, shattering, and leaving graphite dust behind. The wood, too, can make it a serious fire risk in the pressurized, oxygen-rich capsule. All of these common issues become life-threatening hazards in space.

Still, there were attempts to bring pencils into space. In 1965, the agency famously ordered 34 specially designed mechanical pencils in hopes of finding the perfect writing tool for astronauts. But at $128 each, they weren't exactly cheap, and it only got worse when the public got wind of the price. Thankfully, an alternative was not too far behind.

The Space Pen was invented by Paul Fisher, head of Fisher Pen Company. Unlike a typical pen, the Fisher Space Pen uses compressed nitrogen to force ink out of the nozzle, instead of using gravity to make it flow. This made it the ideal device for writing in space, while upside down, or submerged underwater. It wrote crisp and clean, without the safety concerns of a pencil.

Fisher contacted NASA to give his pens a try in 1965 and in 1967, after months of testing, they were impressed enough to bulk buy 400 of them for future missions. Contrary to those urban legends, NASA didn't commission the pen or contribute any funding to it. The Soviets soon ditched their grease pencils and were eventually buying the same Fisher pens as NASA, too. The price? After a 40 percent discount from Fisher, both space agencies were paying $2.39 a pen.

The Fisher Space Pens made their debut in 1968 on the Apollo 7 mission and have been involved in all manned missions since.

So, the short reason is that astronauts only used pencils when they were waiting for something better to come along. As soon as it did, they switched and never looked back. Even the Russians thought it was a good idea.

New Study Says We Could Be Alone in the Universe

There's a good chance that humans are the only intelligent life in the galaxy, according to a new study submitted to the journal Proceedings of the Royal Society of London A. As Quartz reports, researchers at Oxford University's Future of Humanity Institute applied existing knowledge of biology, chemistry, and cosmology to the Drake equation (below). It was created by astronomer Frank Drake in 1961 as an attempt to calculate the number of intelligent civilizations that could be in our galaxy. He included factors like the average rate of star formation and the average lifespan of intelligent civilizations.

They estimate there’s a 53 to 99.6 percent chance we’re alone in the galaxy, and a 39 to 85 percent chance we’re the only intelligent life to be found in the entire universe.

“Where are they?” the researchers ask, referring to the classic Fermi Paradox, which asserts that intelligent extraterrestrial beings exist and that they should have visited Earth by now. “Probably extremely far away, and quite possibly beyond the cosmological horizon and forever unreachable.”

Seth Shostak doesn’t buy it. Shostak is senior astronomer at the SETI Institute, a research organization that analyzes radio signals for signs of extraterrestrial intelligence. Part of the challenge with mathematical modeling like this, Shostak says, is that the data are limited; scientists just haven’t looked at very many star systems.

“I could walk outside here in Mountain View, California and not see too many hippos strolling the streets,” he tells Mental Floss. “But it would be incorrect for me to say on that rather limited basis that there’s probably no hippos anywhere. It’s a big conclusion to make on the basis of a local observation.”

Moreover, they may not even know what to look for in the solar systems they have reviewed. The SETI Institute examines radio communications and light signals, but there’s always the possibility that an intelligent civilization has attempted to contact us using means we may not have developed or even considered yet.

The Fermi Paradox itself may be naïve in its understanding of the universe, Shostak says. “You could have said the same thing about Antarctica in the 1700s. A lot of people wondered, ‘Is there a continent down there?’ On the one hand, you could argue there was [a continent], and on the other hand, you could say, ‘Look, there’s an awful lot of water in the Pacific and the Atlantic, and there’s no continents there, so why should there be one at the bottom of the ocean?’”

In other words, any conclusions about the existence of extraterrestrial intelligence are likely to be presumptive, made before any solid data is released or discovered. The truth may be out there, Shostak says. We just haven’t found it yet.
