The Milky Way's X-Shaped Central Cloud of 10,000 Million Stars --New Revelations from the ESO Telescopes
Story on: TheDailyGalaxyNews
One of the most important and massive parts of the galaxy is the X-shaped galactic bulge. This huge central cloud of about 10 000 million stars spans thousands of light-years, but its structure and origin were not well understood.
Unfortunately, from our vantage point from within the galactic disc, the view of this central region — at about 27 000 light-years' distance — is heavily obscured by dense clouds of gas and dust. Astronomers can only obtain a good view of the bulge by observing longer wavelength light, such as infrared radiation, which can penetrate the dust clouds.
The very wide-field view of the Milky Way above shows the extent of the new VISTA infrared image of the center of the galaxy. These data cover the region known as the bulge of the galaxy and have been used to study a much larger number of individual stars in the central parts of the Milky Way than ever before. The region covered by the new VISTA mosaic is shown as a rectangle.
Earlier observations from the 2MASS infrared sky survey had already hinted that the bulge had a mysterious X-shaped structure. Now two groups of scientists have used new observations from several of ESO's telescopes to get a much clearer view of the bulge's structure.

The NEW equation that will estimate the number of detectable, advanced, extraterrestrial civilizations in the Milky Way galaxy.

N = N*FQ*FHZ*FO*FL*FS
Such That:
1: The average number of stars to form per year in the galaxy.
2: The fraction of those stars that form planets.
3: The fraction of those planets that could support life.
4: The fraction of life-supporting planets that form life.
5: The fraction of those living planets that develop intelligent life forms.
6: The fraction of those intelligent life forms that develop technology.
7: The average lifetime of a communicating species; in other words how long a civilisation will use radio technology, leaking signals into space for us to hear.

What is a "Field" in Physics?
George Musser, in this short video, gracefully breaks down the heady topic of what a field actually is.
There are many fields in Physics. Gravitational Field, Higgs Field, Gluon Field, etc. Musser, from Scientific American, explains every particle and force has its own separate field.

Physicists Calculate Number of Universes in the Multiverse | MIT Technology Review
One of the curious developments in cosmology in recent years has been the emergence of the multiverse as a mainstream idea. Instead of the Big Bang producing a single uniform universe, the latest thinking is that it produced many different universes that appear locally uniform.
