This Newspaper Article Was Hyping the 2017 Eclipse All the Way Back in 1932


If you’ve turned on a news station or browsed the internet recently, you’ve likely learned of the total solar eclipse set to pass over the U.S. on Monday, August 21. Many outlets (Mental Floss included) have been talking up the event for months, but the earliest instance of hype surrounding the 2017 eclipse may have come from The New York Times.

Meteorologist Joe Rao presented this news clip at a recent panel on the solar eclipse at the American Museum of Natural History, and fuel analyst Patrick DeHaan shared the image on Twitter earlier this year. It shows a New York Times article from August 1932, selling that year’s eclipse by saying it will be the "best until Aug. 21, 2017."

The total solar eclipse on August 21 won’t be the first to fall over U.S. soil in 85 years. The next one to follow the 1932 eclipse came in 1970, but an author at the time apparently predicted that "poor skies" would be likely for that date. That early forecast turned out to be correct: There were clouds over much of the path of totality in the southeastern U.S. The next total eclipse visible from America, which the article doesn’t mention, happened in 1979. Overcast skies were a problem for at least some of the people trying to view it that time around as well.

The upcoming total eclipse will hopefully be worth the decades of hype. Unlike the previous three, which only skimmed small sections of the lower 48 states, this next eclipse will be visible throughout day as it travels from coast to coast.

Even if you stare closely at this seemingly grainy image, you might not be able to tell there’s anything to it besides visual noise. But it's not static—it's a sliver of the distant universe, and every little pinprick of light is a galaxy.

As Gizmodo reports, the image was produced by the European Space Agency’s Herschel Space Observatory, a space-based infrared telescope that was launched into orbit in 2009 and was decommissioned in 2013. Created by Herschel’s Spectral and Photometric Imaging Receiver (SPIRE) and Photodetector Array Camera and Spectrometer (PACS), it looks out from our galaxy toward the North Galactic Pole, a point that lies perpendicular to the Milky Way's spiral near the constellation Coma Berenices.

Each point of light comes from the heat of dust grains between different stars in a galaxy. These areas of dust gave off this radiation billions of years before reaching Herschel. Around 1000 of those pins of light belong to galaxies in the Coma Cluster (named for Coma Berenices), one of the densest clusters of galaxies in the known universe.

The longer you look at it, the smaller you’ll feel.

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.
