If aliens exist, this moon is where we'll probably find them.

NASA is making plans to send a probe to Europa — one of Jupiter's more than 60 moons — and you wanna know why we should all be excited about this?

There's a chance (probably a good one) they're gonna find aliens there.

He's not mad, he's just excited about so much science happening. GIF from "Star Wars: A New Hope."

Here's the thing — while Europa's surface might look like a big, dusty rock, it's actually ice. And below that ice might be a gigantic ocean.

Seriously, Europa's ocean is huge. Even though Earth is more than four times larger in diameter than Europa, it is estimated that Europa has more than twice as much ocean water.

That's important because liquid water and life are totally in love with each other. In fact, just about every place on Earth where we've found liquid water, we've found life.

High in the atmosphere? Check. Buried under miles of rock? Is there water? Then there's life! There's even bacteria inside nuclear waste disposal dumps!

Life, uh, finds a way. Image from Michael Daly/Uniformed Services University/Wikimedia Commons.

So, if there is liquid water under Europa's icy surface, it is extremely likely that there are signs of life below.

OK, yes, we know, we know — if the entire moon is covered in ice, then how is that alien life getting energy? Doesn't it need sunlight?

And that's very astute of you to wonder — but here's your answer: On Earth, deep-sea vents are capable of powering entire alien ecosystems.

Yes, Europa's icy surface probably means the oceans are completely dark, and yes, most food chains on Earth are based around the sun, but let us introduce you to our little friend: thehydrothermal vent.

On Earth, these vents exist deep under the ocean where sunlight never penetrates. Instead the life around them gets its energy from the superheated water and chemicals that erupt up from vents.

Europa is constantly being squeezed by Jupiter's gravity like an giant stress ball, which means it probably has an active, molten core just like Earth's.

A molten core means vents, and vents may mean life. In fact, there's even a theory that suggests life on Earth first developed around similar vents on Earth!

To find out if there is life under Europa's icy surface, scientists are sending a probe into orbit around Jupiter that will also make close passes by Europa.

This will give the probe a chance to examine the moon, using tools like radar and spectrometers to learn more about its geology, it's stress-ball relationship with Jupiter, and what kinds of processes might be going on under the ice.

But that's not even the coolest thing about the probe — the coolest thing is the taste test the probe will conduct on one of its trips past Europa.

Images from the Hubble Telescope hint that giant plumes of water sometimes blast out of Europa's ocean like geysers, shooting some of its ocean water high into space.

The scientists are planning to add a bunch of robot tongues — essentially — to the front of their spacecraft and send it diving through the spray from these geysers to "taste" all that water and see what kinds of chemicals or possible lifeforms it can detect.

If there are aliens to be found, it's likely we'd find some trace of them on Europa. Meaning this mission could be the single biggest scientific discovery ever.

OK, so if they do find aliens, they're probably not going to look as pretty as Spock...

GIF from "Star Trek."

...or as be as suave as Chewie.

In fact, they'll probably look more like bacteria or algae. But alien algae would be totally cool too – because anything we find down there that's alive would totally revolutionize our concept of life in the universe. If life is so common that it could arise twice around a single star, then imagine what an entire galaxy's worth of planets and moons and stars could look like.

And even if they don't find any aliens, this mission is still worth celebrating because it's an awesome chance for us to explore our solar system and learn more about the universe we live in.

Watch NASA's animation about their mission to Europa below. And get excited! This could be the first step to finding aliens — real aliens — in our lifetime.

Easy (and free!) ways to save the ocean

The ocean is the heart of our planet. It needs our help to be healthy.

Ocean Wise

Volunteers at a local shoreline cleanup

True

The ocean covers over 71% of the Earth’s surface and serves as our planet’s heart. Ocean currents circulate vital heat, moisture, and nutrients around the globe to influence and regulate our climate, similar to the human circulatory system. Cool, right?

Our ocean systems provide us with everything from fresh oxygen to fresh food. We need it to survive and thrive—and when the ocean struggles to function healthfully, the whole world is affected.

Pollution, overfishing, and climate change are the three biggest challenges preventing the ocean from doing its job, and it needs our help now more than ever. Humans created the problem; now humans are responsible for solving it.

#BeOceanWise is a global rallying cry to do what you can for the ocean, because we need the ocean and the ocean needs us. If you’re wondering how—or if—you can make a difference, the answer is a resounding YES. There are a myriad of ways you can help, even if you don’t live near a body of water. For example, you can focus on reducing the amount of plastic you purchase for yourself or your family.

Another easy way to help clean up our oceans is to be aware of what’s known as the “dirty dozen.” Every year, scientists release an updated list of the most-found litter scattered along shorelines. The biggest culprit? Single-use beverage and food items such as foam cups, straws, bottle caps, and cigarette butts. If you can’t cut single-use plastic out of your life completely, we understand. Just make sure to correctly recycle plastic when you are finished using it. A staggering 3 million tons of plastic ends up in our oceans annually. Imagine the difference we could make if everyone recycled!

The 2022 "Dirty Dozen" ListOcean Wise

If you live near a shoreline, help clean it up! Organize or join an effort to take action and make a positive impact in your community alongside your friends, family, or colleagues. You can also tag @oceanwise on social if you spot a beach that needs some love. The location will be added to Ocean Wise’s system so you can submit data on the litter found during future Shoreline Cleanups. This data helps Ocean Wise work with businesses and governments to stop plastic pollution at its source. In Canada, Ocean Wise data helped inform a federal ban on unnecessary single-use plastics. Small but important actions like these greatly help reduce the litter that ends up in our ocean.

Ocean Wise, a conservation organization on a mission to restore and protect our oceans, is focused on empowering and educating everyone from individuals to governments on how to protect our waters. They are making conservation happen through five big initiatives: monitoring and protecting whales, fighting climate change and restoring biodiversity, innovating for a plastic-free ocean, protecting and restoring fish stocks, and finally, educating and empowering youth. The non-profit believes that in order to rebuild a resilient and vibrant ocean within the next ten years, everyone needs to take action.

Become an Ocean Wise ally and share your knowledge with others. The more people who know how badly the ocean needs our help, the better! Now is a great time to commit to being a part of something bigger and get our oceans healthy again.

Family brings home the wrong dog from daycare until their cats saved the day

A quick trip to the vet confirmed the cats' and family's suspicions.

Family accidentally brings wrong dog home but their cats knew

It's not a secret that nearly all golden retrievers are identical. Honestly, magic has to be involved for owners to know which one belongs to them when more than one golden retriever is around. Seriously, how do they all seem have the same face? It's like someone fell asleep on the copy machine when they were being created.

Outside of collars, harnesses and bandanas, immediately identifying the dog that belongs to you has to be a secret skill because at first glance, their personalities are also super similar. That's why it's not surprising when one family dropped off their sweet golden pooch at daycare and to be groomed, they didn't notice the daycare sent out the wrong dog.

See, not even their human parents can tell them apart because when the swapped dog got home, nothing seemed odd to the owners at first. She was freshly groomed so any small differences were quickly brushed off. But this accidental doppelgänger wasn't fooling her feline siblings.

This woman's powerful 'before and after' photos crush myths about body positivity

"Body positivity is about saying that you are more than a body and your self-worth is not reliant on your beauty."



Michelle Elman, a body positivity coach, helps people who are struggling to find confidence in their own skin.

After persevering through numerous medical conditions and surgeries in her own life, Elman realized a few years ago that body positivity wasn't just about size or weight. Things like scars, birthmarks, and anything else that makes us feel different of self-conscious have to be a part of the conversation, and she tries to make the movement accessible to everyone.

Sharing her own journey has been one of her most effective teaching tools.

You can't not sing this song.

The music of Queen has a profound visceral effect on everyone. Few pieces of art can cause complete strangers to put aside their differences and come together in song, but by golly, “Bohemian Rhapsody” is one of them. It would be cheesy if it weren’t so absolutely beautiful.

This pertains even to non-English-speaking countries, it appears. Recently, thousands of Harry Styles concertgoers in Warsaw, Poland, began cheering as those iconic beginning piano notes penetrated the air.

You know that feeling you get when you walk into a classroom and see someone else's stuff on your desk?

OK, sure, there are no assigned seats, but you've been sitting at the same desk since the first day and everyone knows it.

So why does the guy who sits next to you put his phone, his book, his charger, his lunch, and his laptop in the space that's rightfully yours? It's annoying.

The 25-year-old money-saving 'bible' that millennials and Gen Zers absolutely need to read

This book has saved me thousands of dollars and changed my entire perspective on "frugality."

"The Complete Tightwad Gazette" offers timeless money-saving advice.

Let me start by saying that young adults these days absolutely do have economics stacked against them. There's no question that stagnant wages, the unaffordability of housing, outrageous college costs, post-pandemic inflation and good ol' American corporate greed have all combined to create a tough financial reality for us all, but particularly for the millennials and Gen Zers who are starting off their adult lives feeling already underwater.

If you're in that boat, allow a Gen X auntie to give you some sage advice. Absolutely, rail against the man and shake your fist at the skyscrapers and vent on TikTok if it makes you feel better. But also, none of that is going to change super soon, so you've got to own what you actually have control over, and that's managing the money that you do have (however little it may be).

When my kids were little back in the early 2000s, my husband and I were living on one not-at-all-amazing income. I had been raised quite frugally, so I was comfortable penny-pinching as needed, but I was looking for more creative ways to stretch our dollars.

I had no idea how much one book would change my entire view of saving money—or how much money it would actually save me over the years.
