Milky way galaxy map
Like early explorers mapping the continents of our globe astronomers are busy charting the spiral structure of our galaxy the milky way. Galaxy map brings together the latest scientific results mapping our home galaxy the milky way.
Charting The Milky Way From The Inside Out Nasa
Our sun is buried deep within the orion arm about 26 000 light years from the centre.
These are young stars which are four to 20 times larger than our sun and upto 100 000 times as bright. Towards the centre of. A map of the milky way this is a drawing of the milky way looking down from above. The scientists used the locations of 1339 standard stars to map the outline of the milky way galaxy called classical cepheids.
Clouds of dust permeate the milky way blocking our view of the galaxy s stars. This map shows the full extent of the milky way galaxy a spiral galaxy of at least two hundred billion stars. A landmark study has allowed scientists using nasa s hubble space telescope to map out the halo of the andromeda galaxy that has already intersected the halo of our own milky way galaxy. Like cepheids rr lyrae pulsate in.
In the future the researchers plan to refine their 3d map of the milky way by charting the distances between the sun and other pulsating stars known as rr lyrae. Using infrared images from nasa s spitzer space telescope scientists have discovered that the milky way s elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars. Nasa revealed in a thursday news release that scientists operating the hubble space telescope mapped out the massive halo or envelope of gas belonging to the andromeda galaxy our milky way galaxy s largest and nearest neighbor. Today researchers have a suitable map of our galaxy s spiral structure but like early explorers charting new territory they continue to patiently and meticulously fill in the blanks.
The sun is just one of 200 billion stars in this typical barred spiral galaxy that is about 90 000 light years in diameter. If you are new to this site you may want to start with the section on the basic plan of the milky way and take a look at some of the other chapters in our galactic region. For this picture is provided below. Mapping an entire galaxy from earth is like trying to figure out india s outline while sitting in a delhi office.
