SaintWacko, w After 30 years, I'm finally going to see a total solar eclipse. Also, Potato World is a thing.

I’m camping in the middle of nowhere southeast Oklahoma, praying this cloud cover lifts in time

Unrelated, but I just wanted to say that rotating Mars icon for the channel looks pretty slick.

VubDapple, w After 30 years, I'm finally going to see a total solar eclipse. Also, Potato World is a thing.

Store the memory of this wonderful milestone in your life where you can reflect on a life well spent and be embedded in the feeling of belonging to a loving family. That shit is GOLD and will protect your mental health like a Patronus Charm from Harry Potter.

GammaGames, w Fake Vs Counterfeit Eclipse Glasses. Did You Get Any?

Pretty much every gas station I’ve been to the past week had a box of glasses

RememberTheApollo_, w [Eric Berger] Seeing this eclipse is probably the highest-reward, lowest-effort thing one can do in life

I can imagine the traffic jams anywhere along the path of totality. It’s gonna be a mess. We already booked a place in the path, but it’s in the sticks and I’m not looking forward to the lengthy drive back to civilization.

Develop the fucking US economy.

Man, we were warned not to go to Europa!

It’s interested that they say “oxygen could travel below the ice and support life.”

I would expect life on Europa to be anaerobic, given the obvious lack of photosynthesis.

kat_angstrom, w The mathematically perfect exoplanet system — a great place to search for alien tech

Damn, the article never actually defined what they meant by “mathematically perfect” :(

The first link leads to an older article that does explain it. What they mean is that the planets’ orbits are in resonance, which means that their orbital periods are related by integer ratios. (For example one planet completing exactly three orbits in the time it takes another to complete two)

There goes the real estate market.

Here’s the Ponzo illusion that they describe instead of just including:

Tristaniopsis, w A sleuthing enthusiast says he found the US military’s X-37B spaceplane

If he’s an American or ally, why doesn’t he STFU?

vzq,

Because in a democracy we have a right to do research and publish our results.

Shittyretar_,

Despite the secrecy, it’s difficult to imagine the US military’s adversaries in China and Russia didn’t already know where the spaceplane was flying.

From the article.

OsrsNeedsF2P,

If he’s an American

Because many Americans realize their army terrorizes most of the world?

Our navy terrorizes most of the world. The US Army just figured out Class A uniforms. There is no reason why the Bundeswehr should outshine us in uniform design. It’s a tailoring gap we must overcome before we can conquer ze world. So you have nothing to worry about, except coming up with better comments.

danl,

It’s not a secret, just hard for amateurs to do. No doubt states with space monitoring equipment always knew. He just did it with a camera in his backyard and his laptop.

Also, he’s Finnish.

Amateur observations of the spaceplane indicate it is flying in a highly elliptical orbit ranging between 201 and 24,133 miles in altitude (323 and 38,838 kilometers). The orbit is inclined 59.1 degrees to the equator.

This is not far off the predictions from the hobbyist tracking community before the launch in December. At that time, enthusiasts used information about the Falcon Heavy’s launch trajectory and drop zones for the rocket’s core booster and upper stage to estimate the orbit it would reach with the X-37B spaceplane.

Tristaniopsis,

Ok fair enough.

Love this story.
