Our home galaxy, the Milky Way, makes for a pretty space picture, and it looks normal at a distance. But a new 3D map reveals a surprise: The Milky Way is being warped and twisted by its stars.
The Milky Way is a spiral galaxy, in which stars and gas clouds exist mainly in its two spiral "arms." Our massive neighbor, the Andromeda galaxy, is also a spiral. Spiral galaxies usually appear very flat and easy to see through a telescope, said the researchers behind the new map, published Monday in the journal Nature Astronomy.
Using 1,339 large, pulsating stars to compile a 3D map of the Milky Way, researchers discovered instead that the galaxy's disk of stars is increasingly twisting, most likely due to the spinning of the disk. And the farther the stars are from the center, the more twisted it becomes.
The stars used to create the map are called classical Cepheids. These are young stars, between four and 20 times the mass of our sun and 100,000 times brighter. Given their mass and brightness, they probably burn through their fuel quickly and die after a few million years -- young for the lifetime of a star.
Previously, astronomers saw evidence of hydrogen clouds becoming warped in the Milky Way. This isn't completely abnormal, because astronomers have noticed the same pattern of progressively twisting spirals in about a dozen other galaxies. But it does help them make more sense of our galaxy.

WE’RE ALL GONNA DIE!!!!!...................again...............
What about the Mars Bars..are they unmolested?
If true, we might be living in one of Arp’s irregular galaxies. Something really big must have merged with the MW, to do this.
“The Milky Way is being warped and twisted, study says”
Must be a bunch of Democrats flying around up there.
Now THAT is funny!!!!
Intergalactic socialist perverts at it again?
That is why I prefer Snickers. The peanuts prevent warpage and twistage by adding just the right amount of rigidity.
Yes it is!
I remember reading an article stating, that if we could see it, the Andromeda galaxy would fill a quarter of the night sky.
Now American Capitalism is actually destroying the universe itself.
Warped and twisted ping.
Kinda like what CNN does with the news ...
Trump’s fault !
An artist's impression of a collision between the Milky Way and a smaller dwarf galaxy, such as that which occurred about eight to 10 billion years ago.
Mars bars have been warped and twisted ever since they took the almonds off the top and ground them up and put them in the nougat.
