Map Of Stars
Like a misshapen potato chip, our home galaxy is warped. A new 3-D map brings the contorted structure of the Milky Way’s disk into better view, thanks to measurements of special stars called Cepheids, Rather than being flat as a Frisbee, the Milky Way’s star-studded disk is twisted and warped, according to a new three-dimensional map of our home galaxy. If viewed from the side, the spiral arms The map and accompanying study were published Thursday in the journal Science. The stars used to create the map are called classical Cepheids. These are young stars, between four and 20 times the mass
The farther away the star is, the dimmer it should appear to telescopes on Earth. Both papers use Cepheids to map the galaxy, but used different instruments to detect and categorize the stars. Skowron Astronomers have presented a twist on how we see our galaxy, the Milky Way, with a new three-dimensional map. Our galaxy was generally thought to be a flat disc consisting of some 250 billion stars. Our galaxy is filled with hundreds of billions of stars, but plotting where they are in relation to one another is a cosmic cartographical undertaking. But a new study in Science this week uses an old
Map Of Stars – In the new study, researchers sought to directly measure distances between the sun and a large sample of stars to help construct a 3D map of the galaxy. They focused on a specific kind of star known We don’t have a GPS system for our “warped and twisted” galaxy so astronomers have to get crafty when it comes to pinpointing our location among the stars and creating maps of the Milky Way. We’ve The Milky Way’s S-shaped curve is still a mystery. But now scientists have mapped it in detail by measuring the distances of thousands of stars.
