It's About Space

Sudden Impact

China’s Tiangong-1 spacecraft has been flying above Earth, completely out of control, since September 2016. Since then, agencies around the world have been monitoring the vehicle, trying to project where it will crash -- on or about April 3. Many experts have predicted that it might hit Detroit. 

Of all the places the 8 ton space hulk, filled with toxic chemicals, could hit, a Detroit impact would cause the least damage, and might even help restore the place if it wiped out the city's leadership and their minions.

Sifting out debris from the toxic Chinese space station from the local landscape in the post-Apocalyptic-looking City of Detroit might take some time. There are a lot of Iraqi immigrants living in that area. The toxic strike could make the place feel even more like home for them.

That Pesky Sun

New research from the University of New Hampshire's Space Science Center cautions that the exposure to radiation is much higher than previously thought and could have serious implications on both astronauts and satellite technology.
"The radiation dose rates from measurements obtained over the last four years exceeded trends from previous solar cycles by at least 30 percent, showing that the radiation environment is getting far more intense," said Nathan Schwadron, professor of physics and lead author of the study. "These particle radiation conditions present important environmental factors for space travel and space weather, and must be carefully studied and accounted for in the planning and design of future missions to the moon, Mars, asteroids and beyond."
In their study, recently published in the journal Space Weather, the researchers found that large fluxes in Galactic Cosmic Rays (GCR) are rising faster and are on path to exceed any other recorded time in the space age. They also point out that one of the most significant Solar Energetic Particle (SEP) events happened in September 2017 releasing large doses of radiation that could pose significant risk to both humans and satellites. Unshielded astronauts could experience acute effects like radiation sickness or more serious long-term health issues like cancer and organ damage, including to the heart, brain, and central nervous system.

Update on the worsening particle radiation environment observed by CRaTER and implications for future human deep-space exploration. Space Weather, 2018; DOI: 10.1002/2017SW001803
For most of the space age, the sun's activity ebbed and flowed like clockwork in 11-year cycles, with six- to eight-year lulls in activity, called solar minimum, followed by two- to three-year periods when the sun is more active. However, starting around 2006, scientists observed the longest solar minimum and weakest solar activity observed during the space age.

Despite this overall reduction, the September 2017 solar eruptions produced episodes of significant Solar Particle Events and associated radiation caused by particle acceleration by successive, magnetically well-connected coronal mass ejections. The researchers conclude that the radiation environment continues to pose significant hazards associated both with historically large galactic cosmic ray fluxes and large but isolated SEP events, which still challenge space weather prediction capabilities.

Despite the differences in heat coming off the Sun and striking the Earth, progressives cling to the notion that only man causes changes in the climate -- ignore historical science. 10,000 years ago Detroit was under 4,000 feet of ice...

Tabby's Star

A team of more than 200 researchers, including Penn State Department of Astronomy and Astrophysics Assistant Professor Jason Wright and led by Louisiana State University's Tabetha Boyajian, is one step closer to solving the mystery behind the "most mysterious star in the universe." KIC 8462852, or "Tabby's Star," nicknamed after Boyajian, is otherwise an ordinary star, about 50 percent bigger and 1,000 degrees hotter than the Sun, and about than 1,000 light years away. However, it has been inexplicably dimming and brightening sporadically like no other. Several theories abound to explain the star's unusual light patterns, including that an alien megastructure is orbiting the star.

The mystery of Tabby's Star is so compelling that more than 1,700 people donated over $100,000 through a Kickstarter campaign in support of dedicated ground-based telescope time to observe and gather more data on the star through a network of telescopes around the world. As a result, a body of data collected by Boyajian and colleagues in partnership with the Las Cumbres Observatory is now available in a new paper in The Astrophysical Journal Letters.
"We were hoping that once we finally caught a dip happening in real time we could see if the dips were the same depth at all wavelengths. If they were nearly the same, this would suggest that the cause was something opaque, like an orbiting disk, planet, or star, or even large structures in space" said Wright, who is a co-author of the paper, titled "The First Post-Kepler Brightness Dips of KIC 8462852." Instead, the team found that the star got much dimmer at some wavelengths than at others. 
"Dust is most likely the reason why the star's light appears to dim and brighten. The new data shows that different colors of light are being blocked at different intensities. Therefore, whatever is passing between us and the star is not opaque, as would be expected from a planet or alien megastructure," Boyajian said.
Now there are more answers to be found. "This latest research rules out alien megastructures, but it raises the plausibility of other phenomena being behind the dimming," Wright said. "There are models involving circumstellar material -- like exocomets, which were Boyajian's team's original hypothesis -- which seem to be consistent with the data we have." Wright also points out that "some astronomers favor the idea that nothing is blocking the star -- that it just gets dimmer on its own -- and this also is consistent with this summer's data."

Personality Disorders

Elizabeth "Fake Indian" Warren is now fighting the political battle of her life against those accusing her of faking her ancestry to advance her career. 

In the latest incident, someone suggested she take a DNA test to prove her heritage. She's so sure about her heritage that she's "not going to let someone take it away" with a DNA test. 

She announced that if nominated she would not run and if elected she would not serve as President of the United States -- but what could be more progressive than to have a fake Indian female as president? Actually, I think it would be as fun to watch Sen. Elizabeth Warren (D-MA) run as it would to watch Rep. Nancy (Nasty) Pelosi (D-CA) run. 

About IQ

Rep Maxine Waters (D-CA) is outraged that President Trump suggested that her IQ was somewhere close to the temperature of 'tap waters'. She said that it was, "outrageous for the president to ask an aging woman of color to pee into a cup to prove her IQ."

Then there is that other old negro woman in the House of Representatives who wears that repellant ratty old wig with a cowboy hat perched on top - Frederica Wilson (D-FL). Somebody professional needs to take a close look at that personality disorder.

I realize that she's somebody's daughter and may even be somebody's mother so poking fun at her would be wrong if she didn't poke so much fun at herself.

How can anyone take that seriously?
