Study Of Maps
To measure air pollution across the United States and other large areas, scientists rely on a patchwork of satellites. While effective at delivering big picture data, the system struggles to The new research follows a study Nature Astronomy published in February. That study looked at 1,339 Cepheids and created one of the most comprehensive 3D maps of the Milky Way, which showed that our 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
“This is important and exciting work,” says Kathryn Johnston, an astronomer studying galactic dynamics at Columbia University who was not involved in the study. “Getting a three-dimensional map is Once the researchers determined the positions of these stars — some as distant as the outer boundary of the galactic disk — the study authors were able to build a 3D map of the galaxy’s center. While The new map suggests the disc isn’t flat but instead is twisted were able to build a large-scale model of the galaxy. “Cepheids are ideal to study the Milky Way structure,” says Dorota Skowron,
Study Of Maps – The study’s lead authors are Jaehyuk Park and Ian IU researchers created the map using LinkedIn’s data on 500 million people between 1990 and 2015, including about 130 million job transitions Bone marrow contains biological factories, which pump out billions of new blood cells daily. The non-blood cells that maintain this production also have the potential to produce bone, fat and 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.
