A recent scientific study found that life on Earth will survive nearly anything
Life could survive pretty much anything the universe is going to throw at us.

Earth faces many challenges moving forward except maybe inhabiting life.

Scientists have calculated what it would take to sterilize the planet. No wait, stay with me! It's not as morbid as it sounds!
Three scientists from Oxford and Harvard universities were interested in just what it would take to sterilize the Earth — not just wipe out humanity, but get a really deep scrub in there and completely wipe out life.
What they found is that life could survive pretty much anything the universe is going to throw at us for at least 7.6 billion years.
To figure this out, they looked at the greatest survivors ever.
Not humans. Not sharks. Tardigrades.
Big, impressive life — humans and whales and Tyrannosaurus rexes — are actually kind of fragile. We depend on very specific environments to survive. But there are much tougher creatures out there, wriggling around, like tardigrades.

After doing a bunch of math about radiation and pressure and other factors, the scientists determined the only way to wipe out these little buggers would be to boil the entire ocean. Let me repeat that: The only way to get rid of them is to boil the ocean.
And boiling the ocean just isn't likely to happen anytime soon. You'd have to slam the planet with a truly gigantic asteroid, or hit it with a supernova or an ultra-powerful gamma ray burst. The scientists did the math, and they say all of those are just too rare or too far away to matter to a tardigrade.
"Life, once it gets going, is hard to wipe out," study co-author Dr. David Sloan said in a press release.

GiphyBasically, life on Earth is probably going to survive as long as the sun does.
Unfortunately, there is an end point. In about 7.6 billion years, the sun's going to evolve into a red giant star. At that point, it'll either devour the Earth or be bright enough to, yes, boil the oceans.
That's a long way away. Life has only been on Earth for about 3.8 billion years — multicellular life even less. In only about 600 million years, we went from worms to dinosaurs to Carl Sagan. Imagine what another 7.6 billion years will get us. Life on Earth hasn't even hit middle age yet.
The researchers say this gives hope to the possibility of finding life on other planets.
Perhaps the deep soils of Mars or the volcanic oceans of Europa or Enceladus have their own little microscopic Terminators too.
"If tardigrades are Earth's most resilient species, who knows what else is out there," said Dr. Rafael Alves Batista, a co-author of the study.
That doesn't mean we humans should take our sturdy little home for granted, though.
Remember that tardigrades are little Terminators. We're not. Humans, it turns out, really like Earth the way it is now.
If we want to last as long as the tardigrades do, we have some work ahead of us — like preparing for climate change, protecting the biosphere, and maybe keeping an eye out for some of those smaller asteroids.
But if these scientists are correct, no matter what, life on Earth is going to survive a long, long time.
So take that, universe, you're stuck with us.

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
