The Killington Way is around us, so to shape its shape shape, we would have to map the cellular distributions on either side
From a great distance, the Bugic Slayer would be similar to a tiny disk of stars that move once a hundred hundred million millions around it; main sector. Hundreds of billions of stars present their interesting behavior to maintain them together.
But the trace of diversity is much weaker in a long-term disease. Out there, the hydrogen clouds that make up their & # 39; Most of the seagull's gas disc is restricted to a thin plane. Instead, they are sending a & # 39; goddess looks like S.
Although the Hydrogen Gasfill Festival has surpassed Way on being known for decades, in a research published today Natural History, we found that there is also a huge, big star in the war, and a declined box pattern.

We can confirm its & # 39; This is a busy look after we have been able to improve its & # 39; First detailed three-dimensional photograph of the Milk Route to the far-reaching areas.
Map the sligo trail
Trying to prove the true shape of a galaxy is like to # standing in the Sydney garden and trying to prove Australia's shape. The Killington Way is around us, so to shape its shape shape, we would have to map the cellular distributions on either side.
Although this is not particularly difficult in terms of directions above and lower than the stellar disk engine, it will be harder on a Milk Way plane.
In addition to the stars and the hydrogen gas clouds in the Milky Way of Milk, our vision is heard with lots of dust. The material sciences that contain dust are made up of minibus. It is not too different from the sound that will be built in your home if, for example, your open fire.
Much of the dust will express our opinion on what is further afield, but dust also has a make light look deeper. This is due to the fact that the size of the carbon components is near the light of blue light. So, blue light can be easily embedded with the dust while red and white; go through too much disturbance.
But it's not just a waste that's a? Galaxy problems can map the Way Way galaxy. It is very difficult to set a distance from the Sun to parts of a god outside the Big Slige without a clear indication of what the same is like.
One of the researchers in my international team – Xiaodian Chen of the National Resses Exhibitions (Chinese Academy of Sciences) in Beijing – put together a new catalog of diverse, diverse stars called Cepheids classical. These stars change clearly over time.
These stars are among the best milestones in science: they can be used to set real distances with uncertainty of just 3% to 5%. This is as good as getting into science, and # 39; gives us the right map of our available Milky Way available.
Our new catalog was based on comments made by Explorer Survey Wide-field Infrared Explorer (WISE), spatial telescope with long wave (infrared) waves, suitable for viewing through any obsolete in the Sea Track disc.
The Cepheids are listed from the Firth of the Firth through the Firth to its outermost areas, most of which are beyond the center of galaxy due to attractive constraints.
Classic Cepheids are the stars of 4 to 20 times as big as Sun, and up to 100,000 times are so clear. These high chances mean that these stars are quick and easy. A young dying, which burns through the hydrogen fuel inside them is very fast, sometimes in a few million years.
Cepheids shows a daily-hit hit, which can easily be viewed as changes in their vision. Along with Cepheid's average clarity, a time of his spell can be used to get the right distance.
We are all together
To the extent of our surprise, we find that our collection of 1,339 Pepheis stars and the gas diary of the Seawalks closely follow each other. Until the recent survey, it was not possible to connect young stars in the outlet of the Big Slige, as well as the graph that was gutted and its & # 39; made up of hydrogen gas clouds.
However, perhaps more importantly, we find that the solo disk is covered in a banner pattern that is converted gradually.
The war has many spiritual galax to different types, such as the ESO 510-G13 (pictured roof) disease in the southern Hydra shape, about 150 million light years of Earth. However, it was known that only twelve other galaxies appeared similar patterns to the same kind of external gods.

We put our findings together with those ideas, we decided that a boot icon that is initiated by a war and is easily turned into by a serious torque from a big dash inside a galaxy. The inside disk that moves, in particular, is a & # 39; pulling out the diary forward, but as the awakening outside the back is reduced because the structure that is in the shape of the ridge is reduced; come as a result of his spiritual pattern.
This new map provides a vital update for surveys of the best motions; from the insects and disc sources of the Sligo. This is particularly interesting because our knowledge policy is the result of the Gaia satellite mission at the European Space Agency.
Gaia aims to finally record our Milk Way in unprecedented information based on the hardest causes of the most wealthy stars ever before.
