Mysterious Transmissions From Deep Space Have Astronomers Speculating

Some say it’s extraterrestrial life forms

For the past six decades, astronomers have pointed radio telescopes into space, hoping that some day, something, somewhere will make contact. Last Friday, a report by Paul Gilster at Centauri Dreams announced that a radio telescope in Russia received faint transmissions from deep space, leading some to speculate that our call into the cosmos has finally been returned. The RATAN-600 telescope in Zelenchukskaya, Russia received a signal from a star system 95 light years away in the constellation Hercules. The signal came from the same direction we sent our first postcard to the stars, the Aricebo Message, back in 1974.

The mysterious signals came from the direction of HD164595, a star very similar to our own. Although HD164595 is about 100 million years younger and its average temperature is 12 kelvin hotter. The star system is known to have one Neptune-like planet in its orbit and possibly others. Given the power of the signal, Gilster believes it could have been sent from a civilization that is technologically advanced enough to harness the entire power of its own star.

Dr. Andrew Siemion, director of the Berkeley SETI research center believes there are three distinct possibilities. “The first is that it is a natural astrophysical phenomenon—a variable radio source of some kind,” he told The Daily Mail. “Another possibility is that it is some kind of terrestrial interference...Or could be an instrumental artifact, like a problem with the data reduction. The third possibility is that it is a bonafide signal from an advanced technology from a distant star.” Since the announcement last Friday, radio telescopes at the Allen Telescope Array in California and the Green Bank Telescope in West Virginia have been pointed in the direction of HD164595, but have yet to detect any new transmissions.

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.
