This image from the Smithsonian’s Submillimeter Array maps the projected density of molecular gas in the central 30 light-years of W49A. Brighter colors mark denser regions. The brightest region at the image center is less than three light-years across, yet it contains about 50,000 Suns’ worth of molecular gas.

Main Point:
Astronomers got a first-ever clear view of a giant star cluster formation in W49A region located on the opposite side of our galaxy. Read more…
This shows the distribution of massive stars in the new study. Our location within the Galaxy is circled in black. (Image credit: J. Urquhart et al. Background image by Robert Hurt of the Spitzer Science Center.)
Main Points:
Scientists have finally confirmed that our Milky Way galaxy has four spiral arms. This confirmation has been done after a study of massive stars in the Milky Way for about 12-years.

Monthly Notices of the Royal Astronomical Society
Study Further:
We live in Milky Way galaxy and that is the reason, we cannot look at its shape from outside – at last not at this time, perhaps in the future we may be able to see – so, the scientists devised a way to deduce its shape from the study of the stars present in it and their distances from us.
Initially, in 1950s, astronomers used radio telescopes to observe our Galaxy with the help of clouds of gas in which new stars are formed. They noted four major arms of the Milky Way galaxy. Then, NASA’s Spitzer telescope looked at low-mass stars in 2008 and showed only two arms resulting in a debate among astronomers.
In the present study, astronomers used several radio telescopes in Australia, USA and China and looked at about 1650 massive stars that had been identified by the RMS Survey. They reassured that our Milky Way galaxy has four spiral arms. Massive stars have less life, i.e. about 10 million years, than lower mass counterparts resulting in their less common presence in galaxies. Read more…
Facebook Inc. is going to experiment video advertisements with a handful of advertisers on its website that would play automatically in news feeds of users, according to The Wall Street Journal citing people, who know the subject.
Don’t worry the ads would not annoy you as they will play without sounds. Users can view and listen to the video by clicking on the advertisement. Moreover, the company has reported that the new ads will not consume mobile data plans as the videos will only download upon connection to WiFi.
According to the reports, this type of advertising would capture a share of about $66.35 billion TV advertising market annually in the United States. This move could significantly increase the company’s advertising revenue.
Although, it is still unclear but according to the journal Facebook could show ads of up to 15 seconds. Read more…
