Newly-discovered ‘hypervelocity stars’ flee our galaxy

Newly-discovered ‘hypervelocity stars’ flee our galaxy | Space Stuff | Scoop.it
Astronomers have discovered dozens of solitary stars that move fast enough to escape the gravitational grasp of the Milky Way galaxy. The stars travel at over 1.5 million kilometers per hour, but scientists have no idea what force drives them.

Sepp Hasslberger's curator insight, January 11, 2014 12:33 PM

The stars move faster as they are caught in the magnetic vortex of our galaxy.

 

Think of the center of the galaxy, the black hole, as a giant magnet. Its rotation creates a magnetic field formed like a toroid, much like any magnet. Those are giant vortices that are shaped in a kind of fat, round doughnut pattern that encloses the galaxy.

 

Stars also have such a vortex and planets do, too. Think of the earth's magnetic field and its interaction with the sun's.

 

The polar vortices could take those stars with them, throwing them out of the main galactic plane and and accelerate them to the observed high velocities...

NASA Unveils Most Amazing View of Jupiter's Watery Moon Europa (Video 4min)

NASA Unveils Most Amazing View of Jupiter's Watery Moon Europa (Video 4min) | Space Stuff | Scoop.it

An incredible, reprocessed picture of Jupiter's moon Europa shows the mysterious natural satellite's amazing colors as they have never been seen before. 

 

"Hidden beneath Europa's icy surface is perhaps the most promising place in our solar system beyond Earth to look for present-day environments that are suitable for life," NASA officials wrote in a statement.


"The Galileo mission found strong evidence that a subsurface ocean of salty water is in contact with a rocky seafloor. The cycling of material between the ocean and ice shell could potentially provide sources of chemical energy that could sustain simple life forms."


Via Sepp Hasslberger
T. Blank's insight:
Any liquid water ocean that has been there "for most of the duration of the solar system" is bound to produce biological entities, and probably some of them fairly complex, like fish or even more advanced life forms that can live in the water. So, to find out more, just send a capsule there with recording equipment and capability to communicate (perhaps via an orbiter) the data it finds.
Now in the video, it says that the water stays liquid because of tidal forces. The general assumption is that Europa is a solid ball of rock or metal that also has water, and that the water is warmed up by forces of friction. We assume the same of the earth - solid ball with some water - but that may not be quite correct.
We should look at the possibility that Europa has, like very probably all planets and stars, a hollow configuration with a central "sun" that's doing the warming.
That would mean that the "Goldilocks zone" is not so much depending on the distance from the central sun, but on the existence of a central point that provides energy in the form of heat and light, as well as the impetus for rotation.
Hollow rotating bodies generally have a shell, more or less thick, which makes for two planetary (or lunar) surfaces, one on the outside of the shell, which is the one we generally see, and one adhering on the inside of the shell, which has the advantage of being bathed in light and heat from the central "sun" that is the heart of the planet/moon.
We should look for an understanding of the insides of planets and moons that does not start out from a solid, rocky ball configuration...
A whole new world (and a whole new view on where life might generally originate) could come to view.

Scientists now believe; Aliens created our species and manipulated our DNA

Scientists now believe; Aliens created our species and manipulated our DNA | Space Stuff | Scoop.it

Researchers who worked for 13 years in the Human Genome Project indicate that they came across an amazing scientific discovery: They believe that the so-called 97% of non-coding sequences in the human DNA is nothing less than the genetic code of extraterrestrial life forms.

 

Originally referred to as "Junk DNA" its functioned remained a mystery for researchers. Now researchers believe that our DNA is extraterrestrial in origin.

 

After extensive analysis with the help of other researchers in diverse fields such as mathematics, chemistry and programing, Professor Chang ventured out and asked if there is a possibility that, what we call "junk DNA" is actually some sort of extraterrestrial code, created by an "Alien" programmer. 

 

Professor Chang further explained "Our hypothesis is that a more advanced extraterrestrial civilization was engaged in creating new life and planting it on various planets. Earth is just one of them."
