Over the weekend, NASA teased some very big news.
More specifically, all weekend long, the agency teased that a major Mars mystery was solved.
This morning's press conference, broadcast live from NASA headquarters in Washington, D.C., on NASA Television and on the agency's website, did not disappoint.

At 11:30 a.m. Sept. 28, 2015, NASA announced that, for the first time, they have evidence of flowing water on Mars.
They're called Recurring Slope Lineae, or RSL. They appear as dark streaks that begin in late spring, grow in the summer, and disappear by fall. Until now, NASA researchers couldn't explain what the streaks were.
Turns out, the streaks are evidence of salty water intermittently moving across the surface of the planet.

But this isn't the first time water's been found on Mars.
(Wait, what?) Yep. Researchers discovered water frozen in small, salty puddles on the planet's surface at night and permafrost at Mars' poles.

But this latest announcement and discovery marks the first time that flowing water has been found on the incredibly cold, harsh planet.
Evidence of moving water could be a huge step forward in the search for life, and it opens up possibilities when it comes to the red planet's ability to sustain human life.
So ... are we sending humans to Mars? Not just yet.

Even with the discovery of moving water, inhabiting the red planet — or even sending humans for a visit — is still a long way off. (Sorry, Matt Damon).
So for now, NASA and other international space agencies are conducting dry runs here on Earth.
Last October, six strangers (three men and three women) were picked to live in a dome on a Hawaiian volcano for eight months to simulate a stay on Mars. NASA backed the study to see if people isolated from civilization can work together and get along. It was essentially "Real World: Red Planet."
Even with successful simulations, NASA estimates the first human-manned mission to Mars won't happen until the 2030s.
That may seem like a long time to wait, especially after today's announcement. But as Dr. Jim Green, director of planetary science at NASA, told the crowd at today's announcement, it's all about safety.
"NASA's approach to exploration is not 'Star Trek.' It's not 'go where no man has gone before,'" he said. "It's really a very methodical approach for which we learn everything about the environment that we're going to subject humans to that we possibly can. ... And I anticipate continuing to do that for many years before humans even get in the vicinity of Mars."
But! This is a major breakthrough, and it lays the groundwork for many missions to come.
While you can't drink the water on Mars (it's much too salty) and you can't grow crops with it (the atmosphere on Mars is too thin), finding moving water on Mars is truly unprecedented and opens a lot of doors for exciting missions and exploration to come.
As astronaut John Grunsfeld said at this morning's announcement, "We are on a journey to Mars, and science is leading the way."

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.
