Milky way map of the galaxy
An incredbile new map to the cosmos reveals the precise locations of more than 1 7 billion stars in the milky way galaxy and some 14 000 objects orbiting our sun. But before it was known as a galaxy it was continue reading take a flight through the most detailed 3d map of the.
Charting The Milky Way From The Inside Out Nasa
The milky way is a spiral galaxy comprised of a bar shaped core region surrounded by a flat disk of gas dust and stars about 120 000 light years wide.
The galaxy s two major arms scutum centaurus and perseus can be seen attached to the ends of a thick central bar while the two now demoted minor arms norma and sagittarius are less distinct and located between the major arms. Specifically it s a barred spiral galaxy because it has a central bar bar shaped structure composed of stars. Researchers fine tune maps of our galaxy s spiral arms using data from nasa s wise mission. The sun is just one of 200 billion stars in this typical barred spiral galaxy that is about 90 000 light years in diameter.
The evidence for this picture is provided below. But occasionally you may find alternative names being used for the spiral arms. This is not uncommon. It is easy to drown in the details of any map so it is useful to start with a basic plan of the milky way.
Scientists venture through galaxy using new three dimensional map. Our galaxy the milky way galaxy the major arms consist of the highest densities of both young and old stars. So this is the most real map of the milky way 3d structure of the milky way. This is a drawing of the milky way looking down from above.
This table lists some of. Our solar system is located about 27 000. The current hypothesis is that the bar structure acts as a type of stellar nursery fueling star birth at their centers. A map of the milky way.
Milky way s 250 billion stars are warped and twisted new 3d model suggests. While the milky way appears as an arch to our eyes it is actually a spiral galaxy a sprawling pinwheel of starlight and dust containing 100 to 400 billion stars. The annotated artist s concept illustrates the new view of the milky way. One of the best and surely the prettiest basic plan illustrations currently available was created by the nasa astronomer artist robert hurt and released in 2008.
The map takes only a few minutes. The minor arms are primarily filled with gas and pockets of star forming activity. The andromeda aka m31 is the closest galaxy to our own milky way. Those who want a more detailed although less complete map can visit the face on map overview.
A larger and unlabelled version of the above map is available here. I have used the most common names for the spiral arms on this map. Hurt s illustration was created to highlight scientific conclusions on the inner galaxy from a team of astronomers led by. This map is constructed from 2000 cepheid variable stars and the yellow dot represents our sun.
