The Longest Total Lunar Eclipse of the 21st Century Lights Up the Skies This Weekend

This weekend's blood moon will be hard to miss: The event will light up the sky for one hour and 43 minutes on July 27, making it the longest total lunar eclipse of the 21st century, according to Space.com.

A blood moon occurs when the Moon passes beneath Earth's shadow, giving it an eerie rust-colored appearance. Just how long the effect lasts depends on the the position of the Moon in relation to the Sun. For this upcoming lunar eclipse, the Moon will pass close to the center of Earth's umbra, or the darkest part of the planet's shadow, extending the duration of the eclipse. The Moon will also be at a point in its orbit where it's farther from us, which means it will spend even more time in Earth's shadow.

The time the Moon spends in the actual umbra will amount to one hour and 43 minutes. It will also spend considerable time in Earth's penumbra, which is the lighter part of its shadow. Including this portion, the eclipse will last 3 hours and 55 minutes in total.

Sky-gazers in North America are out of luck this time around: The blood moon will only be viewable from Africa, the Middle East, southern Asia, and the Indian Ocean region starting at 3:30 p.m. EDT and ending at 5:13 p.m. If you won't be in the right part of the world to catch this particular show, check out this space calendar to see what events are occurring over your neighborhood this summer.

Two Harvard Scientists Suggest 'Oumuamua Could Be, Uh, an Alien Probe

An odd, cigar-shaped object has been stumping scientists ever since it zoomed into our solar system last year. Dubbed 'Oumuamua (pronounced oh-MOO-ah-MOO-ah), it was first seen through the Pan-STARRS 1 telescope in Hawaii in October 2017. 'Oumuamua moved at an unusually high speed and in a different kind of orbit than those of comets or asteroids, leading scientists to conclude that it didn't originate in our solar system. It was the first interstellar object to arrive from somewhere else, but its visit was brief. After being spotted over Chile and other locales, 'Oumuamua left last January, leaving lots of questions in its wake.

Now, two researchers at Harvard University bury a surprising suggestion in a new paper that analyzes the object's movement: 'Oumuamua could be an alien probe. Sure, why not?

First, astrophysicists Shmuel Bialy and Abraham Loeb argue that 'Oumuamua is being driven through space by solar radiation pressure, which could explain its uncharacteristic speed. But for that theory to work, they calculate that the object must be unusually thin. Bialy and Loeb then analyze how such a slender object might withstand collisions with dust and gases, and the force of rotation, on its interstellar journey.

Then things get weird.

"A more exotic scenario is that 'Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization," they write [PDF]. They suggest that ‘Oumuamua could be be a lightsail—an artificial object propelled by radiation pressure—which also happens to be the technology that the Breakthrough Starshot initiative, of which Loeb is the advisory committee chair, is trying to send into space. "Considering an artificial origin, one possibility is that 'Oumuamua is a lightsail, floating in interstellar space as a debris from an advanced technological equipment,” they write.

Their paper, which was not peer-reviewed, was posted on the pre-print platform arXiv.

Loeb is well known for theorizing about alien tech. He previously suggested that intense radio signals from 2007 could be the work of aliens who travel through space on solar sails. However, Loeb acknowledged that this theory deals more with possibility than probability, The Washington Post noted. “It’s worth putting ideas out there and letting the data be the judge,” Loeb told the paper last year.

A Team of Young Women Wants to Send Kyrgyzstan's First Satellite to Space

Kyrgyzstan is one of 123 countries that doesn't have a national space agency. That could soon change, thanks to a group of young programmers and engineers taking the matter into their own hands.

As The Next Web reports, the Kyrgyz Space Program is made up of 12 women ranging in age from 17 to 25 years old. They met in 2017, when journalist and TED fellow Bektour Iskender started a free course in his home country of Kyrgyzstan teaching young women there how to build robots and satellites.

The team has since made it its mission to build a cube satellite (CubeSat)—a smaller type of satellite that costs about $150,000 to put together. If they are able to construct the spacecraft, launch it into orbit, and send it to the International Space Station as planned, the project will mark the first time Kyrgyzstan has sent a satellite into space.

The Kyrgyz Space Program now meets twice a week in the offices of Kloop, a media outlet that's known for its support of feminist causes in a country where women still have a long way to go to reach parity. Even as more women start to get involved in Kyrgyzstan's politics, domestic violence, child marriage, and bride kidnappings are still rampant.

In order to accomplish their goal of sending a Kyrgyz satellite to orbit, the program has launched a crowdfunding campaign. Reaching the $2500-a-month marker means they can construct the CubeSat with guidance from the team who launched Lithuania's first satellite. If they reach the $10,000-a-month threshold, they will be able to send the CubeSat to the International Space Station. You can join the 120 people who've already supported their Patreon page by pledging today.
