Milky Way warps like a Mexican wave and a nearby galaxy is to blame 'Still shaking'

 

THE Milky Way is warping around the edges like a Mexican wave rippling through a stadium and astronomers may have finally nailed down the culprit - the Sagittarius Dwarf Spheroidal Galaxy.

 

The Milky Way galaxy is home to hundreds of billions of stars, including our Sun around which we orbit. Since we cannot see what the galaxy looks like from the outside, most people might imagine the Milky Way resembles a flat disk with two arms coiling around its galactic centre*. But new research has found this mental picture is only partially true, as our home galaxy appears to be warped around the edges like the brim of a hat.

 

(Note: The "galactic centre" is the central Sun in astrology and astrotheology.)

 

According to researchers at the University of Virginia, these warped edges are constantly on the move and, in effect, resemble a crowd at a stadium performing a Mexican wave.

 

Xinlun Cheng, an astronomy graduate student in the University of Virginia’s College and Graduate School of Arts and Sciences, said: "If you have ever seen the audience making a wave in a stadium, it's very similar to that concept.

 

"Each member of the audience stands up and then sits down at the correct time and in the correct order to create the wave as it goes around the stadium.

 

"That's exactly what stars in our galaxy our doing."

Mr Anguiano said: "We can still see the disk of our galaxy shaking as a result."

 

The study has also found the warp completes a lap around the galaxy every 450 million years - a 10th of the age of our planet.

 

Mr Anguiano added: "We’re entering an age in astronomy, especially in galactic astronomy, in which we are measuring the movement of the stars at such a level of precision that we can map their past orbital paths and start to understand how they may have been affected at earlier times and how other galaxies approaching our own interacted with stars as they were being born."
