More heavy stars in galaxies than imagined

After an eight-year survey, astronomers conclude that there are many more heavy stars than previously assumed. The astronomers, including two scientists from the University of Amsterdam (UvA), publish their results in the journal Science. The researchers have examined stars in a nearby galaxy, the so-called Large Magellanic Cloud about 180,000 light-years away.

This research shows that there are 30 per cent more heavy stars than was assumed on the basis of the Salpeter Act (1955). Heavy stars (which are a few hundred times heavier than the sun), in contrast to the lighter versions, are short and end after a supernova explosion as a neutron star or black hole.

According to one of the researchers Alex de Koter of the UvA "studying stars tells us something about the nature of the universe". Astronomers think that heavy stars are the first objects created after the Big Bang. Possibly they have played a role in the formation of galaxies such as our galaxy.

For the second time in history, scientists are transmitting communications to extraterrestrials.

Image
NASA scientists hope to communicate with extraterrestrials. They've drafted a message that they want to launch into space soon. That message is more than a simple 'hi, how are you?' The goal is to give the aliens as much knowledge about our civilization as possible. "The message incorporates basic mathematical and physical ideas to construct a universal means of communication, followed by information regarding the biochemical makeup of life on Earth," said Jonathan Jiang, the primary author. The so-called Beacon In The Galaxy (BITG) is written in binary code and concludes with a digital image of a man and a woman, as well as an invitation to reply. It's delivered from China's FAST (Five-hundred-meter Aperture Spherical Radio Telescope), the world's largest radio telescope. This is only the second time a message like this has been sent into space. This happened for the first time in 1974. Not everyone, incidentally, is ecstatic. Experts are concerned th...
