We have not yet emerged from mourning

I've still got the ninth planet galaxy's most famous iceball on the brain today, partially because I can't stop thinking about our fabulous commemorative t-shirt (have you pre-ordered yours yet? email us at tips-at-mentalfloss-com or leave a comment with your email address), and partially because of all the crazy things I learned last week while reporting this article on the solar system. Here are some assorted tidbits I found that didn't end up in the final story:

  • Europa, a moon of Jupiter, has a saltwater ocean which is probably 100 km deep, much deeper than the Pacific. There may also be volcanoes, which could be heating up the water at the bottom of the ocean -- providing similar conditions to those that support life in deep-water ocean vents here.
  • Scientists first figured out that the moon must have been a chip off the Earthly block by comparing the types of oxygen found in lunar rocks with the types found here at home. The oxygen istotope ratios (how much O16 there is compared to O18) are identical.
  • The Earth has its axis tipped by 23.5 degrees, probably because of the same impact that broke off the Moon. Mars is also tipped by about the same amount. Uranus is tipped by a whopping 90 degrees, and no one knows why.

Also, here's a great new mnemonic for the planets, courtesy of our latest contest winner, Wendell Wittler:

Many very easy mnemonics just seem unnecessarily nonsensical.

Netflix's Most-Binged Shows of 2017, Ranked

Netflix might know your TV habits better than you do. Recently, the entertainment company's normally tight-lipped number-crunchers looked at user data collected between November 1, 2016 and November 1, 2017 to see which series people were powering through and which ones they were digesting more slowly. By analyzing members’ average daily viewing habits, they were able to determine which programs were more likely to be “binged” (or watched for more than two hours per day) and which were more often “savored” (or watched for less than two hours per day) by viewers.

They found that the highest number of Netflix bingers glutted themselves on the true crime parody American Vandal, followed by the Brazilian sci-fi series 3%, and the drama-mystery 13 Reasons Why. Other shows that had viewers glued to the couch in 2017 included Anne with an E, the Canadian series based on L. M. Montgomery's 1908 novel Anne of Green Gables, and the live-action Archie comics-inspired Riverdale.

In contrast, TV shows that viewers enjoyed more slowly included the Emmy-winning drama The Crown, followed by Big Mouth, Neo Yokio, A Series of Unfortunate Events, GLOW, Friends from College, and Ozark.

There's a dark side to this data, though: While the company isn't around to judge your sweatpants and the chip crumbs stuck to your couch, Netflix is privy to even your most embarrassing viewing habits. The company recently used this info to publicly call out a small group of users who turned their binges into full-fledged benders:

Oh, and if you're the one person in Antarctica binging Shameless, the streaming giant just outed you, too.

Netflix broke down their full findings in the infographic below and, Big Brother vibes aside, the data is pretty fascinating. It even includes survey data on which shows prompted viewers to “Netflix cheat” on their significant others and which shows were enjoyed by the entire family.
