The mysterious Red Star Betelgeuse is spinning faster than expected

Astronomer J. Craig Wheeler of The University of Texas at Austin thinks that Betelgeuse, the bright red star marking the shoulder of Orion, the hunter, may have had a past that is more interesting than meets the eye.

Working with an international group of undergraduate students, Wheeler has found evidence that the red supergiant star may have been born with a companion star, and later swallowed that star.

The research is published on Dec. 19th in the journal Monthly Notices of the Royal Astronomical Society.

For such a well-known star, Betelgeuse is mysterious. Astronomers know that it's a red supergiant, a massive star that is nearing the end of its life and so has bloated up to many times its original size.

Someday it will explode as a supernova, but no one knows when. "It might be ten thousand years from now, or it might be tomorrow night," Wheeler, a supernova expert, said.

A new clue to the future of Betelgeuse involves its rotation. When a star inflates to become a supergiant, its rotation should slow down. "It's like the classic spinning ice skater—not bringing her arms in, but opening her arms up," Wheeler said. As the skater opens her arms, she slows down.

So, too, should Betelgeuse's rotation have slowed as the star expanded but that is not what Wheeler's team found.

Infrared images taken of Betelgeuse in 2012 by Leen Decin of the University of Leuven in Belgium with the orbiting Herschel telescope show two shells of interacting matter on one side of Betelgeuse.

No one knows the origin with certainty. But "the fact is," Wheeler said, "there is evidence that Betelgeuse had some kind of commotion on roughly this timescale" - that is, 100,000 years ago when the star expanded into a red supergiant.

Unknown craft caught exiting sub-glacial launch facility in Antarctica

A new discovery in Antarctica. According to Florida Marquis, Google Earth shows a craft that takes off from a secret sub-glacial launch facility in Antarctica.

It is remarkable that the 2019 imagery layer shows the area completely covered with snow. The location that can be seen in the imagery layer of 2010 has been vanished!

Stunning restored authentic footage shows German Flying Discs!

Jeff Rense posted two amazing short clips of German flying saucers restored from old film. the footage also included are many photographs of German flying saucers from the 30s and 40s!


The first clip at the beginning shows a German flying saucer flying over a field while the second clip starts at the 5:30 mark in the video and is labeled “Haunebu Test Flight – Nazi Germany 1939!

This ties in with all the whistleblowers who claim Germany did have antigravity working in the 30s and went on to have bases on the Moon and Mars in the 30s and 40s and created a breakaway civilization. Read full story on German Secret Space Program at UFOcasebook.

Mysterious Humanoid Figure on Air Vehicle appears above Teotihuacan Pyramid of the Moon, New Mexico

Teotihuacan is a vast Mexican archaeological complex northeast of Mexico City. Running down the middle of the site, which was once a flourishing pre-Columbian city, is the Avenue of the Dead. It links the Temple of Quetzalcoatl, the Pyramid of the Moon and the Pyramid of the Sun.


Ancient Teotihucan is surrounded in mysteries. The population with over 150,000 inhabitants vanished without a trace. Teotihuacan‘s layout resembles a computer circuit board with two large processor chips (the Sun Pyramid and the Moon Pyramid) and archaeologists have discovered hundreds of mysterious, metallic spheres buried deep beneath one of the ancient pyramids.

And now a tourist while visiting Teotihuacan on August 28, 2019 captured a very strange object in the sky above the Pyramid of the Moon.


The object can best be described as a humanoid figure sitting on an air vehicle. (the humanoid's position is the same as someone who drives a water scooter).


The photographer has submitted the above original …

Huge Unknown Object Crashes Into The North Side Of The Moon Captured Live

On September 9, 2019 Sky-watcher BruceSeesAll captured a huge unknown space object at the moment it crashes onto the Moons' surface.


Bruce states: "Something huge crashed onto the North Side of the moon... Three explosions after impact and it was smoking on the way down to the moon travelling at high speeds."

Meteorite - Space Junk - UFO?

We may wonder why space agencies remain silence on this impact on the moon!
