NASA Chief Predicts Evidence of Aliens by 2025

Recent discoveries regarding water on other planets have scientists optimistic that we’re not alone in the universe.

At a panel discussion yesterday, NASA chief scientist Ellen Stofan predicted that humans would discover evidence of alien life by 2025. According to the NASA website, Tuesday’s hour-long event focused on “the recent discoveries of water and organics in our solar system, the role our sun plays in water-loss in neighboring planets, and our search for habitable worlds among the stars.” The LA Times reports that the organization draws its newfound optimism about E.T.s from a number of new revelations regarding water on Mars and Ganymede, a moon of Jupiter. The Times quotes Stofan:


“I believe we are going to have strong indications of life beyond Earth in the next decade and definitive evidence in the next 10 to 20 years,” she said. “We know where to look, we know how to look, and in most cases we have the technology.”

“I think we're one generation away in our solar system, whether it's on an icy moon or on Mars, and one generation [away] on a planet around a nearby star,” added John Grunsfeld, associate administrator for NASA's Science Mission Directorate and a former astronaut.

These statements come at a time when wild claims about extraterrestrial life are flying hard and fast around us—have we already found aliens in our own stratosphere? (Eh…) Are other intelligent life forms apt to be 650-pound space monstrosities? ( ¯\\_(ツ)_/¯ ) Does Arizona have a UFO problem? (Likely.) Although Stofan’s timeline is still speculative, NASA’s willingness to weigh in at a forum like Tuesday’s panel reflects an increasing confidence that we are just around the corner from discovering something big. Just don’t expect any ALFs or Morks any time soon.

“We are not talking about little green men,” said Stofan. “We are talking about little microbes.”

Anyone who has ever worked in retail knows that the worst thing about the job, right after the pay, are the unreasonable cheapskates who "want to talk to your manager" to get some money off an item.

They think that throwing a tantrum will save them a few bucks and don't care if they completely embarrass themselves in the process. Sometimes that involves belittling the poor employee who's just trying to get through their day with an ounce of dignity.

Twitter is rallying around a gal named Tori who works at a Target in Massachusetts after she was tweet-shamed by irate chapekate, journalist, and Twitter troll, David Leavitt.

Childbirth is the number one reason American women visit the hospital, and it ain't cheap. In fact, it's getting more and more expensive. A new study published in Health Affairs found that the cost of having a baby with employer-sponsored health insurance increased by almost 50% in the past seven years.

The study evaluated "trends in cost-sharing for maternity care for women with employer-based health insurance plans, before and after the Affordable Care Act," which was signed into law in 2010. The study looked at over 657,061 women enrolled in large employer-sponsored health insurance plans who delivered babies between 2008 and 2015, as these plans tend to cover more than plans purchased by small businesses or individuals.

A meteorite crashed into Earth nearly 800,000 years ago. The meteor was 1.2 miles wide, and the impact was so big, it covered 10% of the planet with debris. However, scientists haven't been able to find the impact site for over a century. That is, until now. A study published in the Proceedings of the National Academy of Sciences journal believes the crash site has been located.

Tektites, which are essentially rocks that have been liquefied from the heat of the impact and then cooled to form glass, help scientists spot the original impact site of a meteor. Upon impact, melted material is thrown into the atmosphere, then falls back to the ground. Even if the original crater has disappeared due to erosion or is hidden by a shift in tectonic plates, tektites give the spot away. Tektites between 750,000 to 35.5 million years old have been found in every continent except Antarctica.
