The Truth About Tabby


UFO and alien conspiracy theory buffs are going to enjoy this post by the gringa, or not. I guess it depends on if you enjoy a healthy dose of conspiracy debunking or truth. You see, dear readers, there has been a bit of hubbub about an interesting space object that is orbiting a nearby star and was detected by the Kepler telescope late last year.

The SETI Institute (Search For Extraterrestrial Intelligence) calls KIC 8462852 “mysterious”. NASA believes the mystery is resolved with the theory that the strange signals are the result of cosmic dust, probably from multiple impacts of a comet swarm, and causes the star’s light to flicker erratically. Vanderbilt University researchers, who affectionately call the star Tabby, debunk theories by those who believe it to be home of aliens who are very, very busy. The astrophysicist contributors to the respectable Astrophysical Journal agree with Vanderbilt’s point of view while at the same time agreeing with theories from other scientists who propose an extraterrestrial origin theory. So, who’s got it right? Who’s got it wrong? Just what the heck is the truth about Tabby?

Who Is Tabby

Tabby is officially designated star KIC 8462852 and shines brighter than our own Sun about 1400 light years from Earth in the Cygnus constellation. It is a subject of study by NASA’s Kepler space telescope which reveals that from time to time it dims about twenty percent in brightness.

SETI’s Conclusion

The cause of the dimming light could possibly be because of material or objects orbiting the star. SETI researchers believe they have evidence to determine that these objects are not planets. SETI considers the possibility that Tabby could be home to a technologically sophisticated society that has constructed a swarm of solar panels that orbit the star which would account for the light fluctuations.

SETI uses its own Allen Telescope Array to study radio signals that originate from that part of outer space. They attest that these radio signals are of artificial origin, calling them “non-natural”. They search for narrow-band signals and broadband that might possibly be produced by a large and powerful spacecraft. They also search for evidence of laser pulses. SETI’s Panamanian partner, Boquete Optical SETI Observatory, performs the laser pulse research.

Research such as this takes a long time so the gringa will have to practice patience for SETI to conclude their studies and publish their final results. They admit that, historically, cases like this usually result in finding a natural cause for the anomalies but they still must investigate the possibility of it originating from extraterrestrial intelligence. That is, after all, their mission.

NASA’s Conclusion

During four years of observation, the Kepler mission recorded strange happenings in 2011 and 2013 when interesting and dramatic light fluctuations occurred. To help determine what happened, NASA also trained the eye of the Spitzer Space Telescope in Tabby’s direction. Kepler observed the visible light. Spitzer could delve deeper into the invisible infrared light signals and patterns. In November of last year Spitzer paid off with a recording of another light fluctuation.

Although NASA’s theory is that clouds of space dust were formed from a swarm of comets that orbit the star in erratic patterns, Spitzer did not discover evidence to support this theory. This caused NASA to switch to a cold comet theory. One lead comet would be followed by a swarm of smaller comets. If this is true, even if the comets were already out of the telescope’s view as they traveled around Tabby, they should still leave behind a detectable infrared signature. However, this was not the case.

Researchers admit that more observations need to be recorded to determine just exactly what is going on. NASA admits that Tabby is strange, indeed. However, they believe that a natural cause is more likely than “little green men”.

Vanderbilt University’s Conclusion

Vanderbilt studies focused on the 100 day period when the most significant light fluctuations occurred. The manner in which they occurred suggested that a large number of “irregularly shaped objects” passed in front of the star causing its light to be blocked temporarily. Working off a report from an astronomer at Louisiana State University who concluded that the star had diminished in brightness by 20 percent over the past century, Vanderbilt finds a natural cause unlikely as an explanation for this. This has become fodder for the theory that a megastructure has been constructed that is absorbing the star’s energy, the solar panel array theory. This is a theory that was reviewed, accepted and published by the Astrophysical Journal.

Vanderbilt, however, did not stop there. They soldiered on. Partnering with amateur German astronomer, Michael Hippke and NASA scientist Daniel Angerhausen, the team began comparing the 20 percent drop in intensity to other stars. They discovered that this is not an unusual phenomenon. In fact, it’s not a star phenomenon at all. It is simply the result of technological changes and advances of human manufactured instrumentation for observance.

The Gringa’s Conclusion

These are all interesting theories but not yet solid answers. So, the gringa will wait and see if, ten or twenty years down the road, we all find out what the actual, final answer is:

  • Comet Swarms

or

  • Extraterrestrial Solar Array

Until then, Tabby will be the most interesting and mysterious star in our night sky.

The Big Mac Boot


The gringa’s oldest son is doing her proud. Like many millenials, my son has a strong desire to make the world a better place. He has aspirations of doing this by becoming a community organizer and rallying people around important issues of social justice, working together to bring about public awareness and positive change. He has taken his first steps toward achieving his goal by volunteering with a local organization and participated in a press conference.

As a proud and supportive parent, and a bit of a rabble-rouser myself, I simply had to devote a post sharing the good work this organization is doing. Please see their press release below. Links are provided to other media coverage or research documents for your own browsing pleasure!

MEDIA RELEASE

Doctors, dieticians, parents call on Texas Children’s, Ben Taub hospitals to give McDonald’s the boot

Coalition announces campaign to eliminate junk food marketing in hospitals

HOUSTON –Today, as part of coordinated actions in five cities nationwide, doctors from the Baylor College of Medicine, Rice University, and Texas Children’s Hospital joined more than 35 health professionals and community organizations to demand that McDonald’s and other junk food corporations end all marketing inside Texas Children’s and Ben Taub hospitals. The coalition is calling on the CEOs of Texas Children’s Hospital and Harris Health System, which oversees Ben Taub Hospital, to close on-site McDonald’s stores, citing health concerns.

The call comes on the heels of Cleveland Clinic’s decision in August and Allina Health/Abbott Northwestern Hospital’s decision in December to sever ties with the burger giant, due to concerns for their patients’ health. It also amplifies the voices of more than 3,000 health professionals and advocacy organizations like Corporate Accountability International who have called on McDonald’s to stop marketing to kids and 12,000 physicians of the Physicians Committee for Responsible Medicine who have urged hospitals, including Texas Children’s Hospital, to go “fast-food-free.” Increasingly, hospital administrators are equating McDonald’s in hospitals to the tobacco industry’s tactic of selling cigarettes in hospital gift shops decades ago.

“In the midst of an epidemic of diet-related diseases, it makes no sense for kids to be treated on one floor of Ben Taub and Texas Children’s and see a McDonald’s on another—it sends the wrong message,” said Rosalia Guerrero, president of Healthcare for All Texas.

Texas Children’s and Ben Taub hospitals would become the twelfth and thirteenth to sever ties with McDonald’s since 2009, joining the ranks of Children’s Hospital of Philadelphia, Truman Medical Center, Vanderbilt Medical Center, and others.

“I was shocked and disappointed to find McDonald’s in the world’s largest medical center,” said Azeen Anjum, first year Baylor College of Medicine student and member of Choosing Healthy, Eating Fresh (CHEF). “McDonald’s symbolizes the toxic dieta ry climate that contributes to America’s current epidemic of diet-related illness. It should not be allowed to continue damaging health in hospitals that serve our community’s most vulnerable populations.”

Siting stores in hospitals is one of the many ways McDonald’s attempts to “nutriwash” its brand.   Increasingly, health professionals are linking the skyrocketing rates of diet-related diseases like Type 2 diabetes to pervasive junk food marketing. Research from the Institute of Medicine and the National Bureau of Economic Research has found that ending kid-targeted junk food marketing could benefit the health of millions of children.

Dietitians from across Houston also weighed in on the issue.

“We are learning more every day about the roles of preservatives, refined sweeteners, oxidized fats and their role in diabetes, blood pressure, cancer, obesity and more” said Ali Miller, RD, LD, CDE author of Naturally Nourished: Food-as-Medicine for Optimal Health. “As a nutrition expert I am confident in saying processed fast food like McDonald’s has been shown to have harmful deleterious effects not neutral.”

This week, hundreds of people in Boston, Chicago, Minneapolis and Tampa are also calling on McDonald’s and other junk food corporations to end targeted marketing through schools and other institutions. The groups are organizing to support of school boards and hospital administrators to strengthen existing policies and sever ties with junk food corporations.

In the coming months, the Houston coalition will continue to build community support for Ben Taub Hospital and Texas Children’s Hospital to prioritize its patients’ health over corporate profits.
