A star was recently spotted speeding at 1.4 million miles an hour (2.2 million km/hr), which happened to be the closest and second-brightest of the so-called hypervelocity stars found so far.
LAMOST-HVS1 (as the object is called, after the Chinese Large Sky Area Multi-Object Fiber Spectroscopic Telescope that discovered it) is about three times faster than most other stars found. Its in a cluster of similar hypervelocity stars above the Milky Ways disk and from its motion, scientists suspect it actually came from our galaxys center.
Whats interesting about the star, besides its pure speed, is it is travelling in a dark matter halo surrounding our galaxies, the astronomers said.
The hypervelocity star tells us a lot about our galaxy especially its center and the dark matter halo, stated Zheng Zheng, an astronomy researcher at the University of Utah who led the study.
We cant see the dark matter halo, but its gravity acts on the star. We gain insight from the stars trajectory and velocity, which are affected by gravity from different parts of our galaxy.
The star is about 62,000 light years from the galaxys center (much further than the suns 26,000 light years) and is about four times hotter and 3,400 times brighter than our own sun. Astronomers estimate it is 32 million years old, which makes it quite young compared to the suns 4.5 billion years.

If Obama had a young sun ..
a star was seen moving at 1.4 million miles an hour....relative to what? exactly?
“What difference does it make!?” :-)
But isn't dark matter unseeable? And dark energy undetectable? So...how was this 'dark matter halo' observed?
Dunno. Point a to point b?
It took one look at that black hole and got the hell outta there!
I would too!
Sure they can, right after they unveil aether's and phlogiston's secrets
Bald opinion statements from the left’s “priestly” (so-called scientific) class.
Science so simple, a panda can do it
Us, I would think.
Original link to the story didn’t work for me. Forget about stars going fast. I’m still trying to wrap my head around the visual of a cow going 60 mph.
All penny-ante, compared to the overmastering effects of orgone.
