A team of scientists from Washington believe that they have managed to establish the exact size of the universe to within 1 per cent accuracy.

In a remarkable development, the researchers, who were working with the Baryon Oscillation Spectroscopic Survey (BOSS), have been able to measure the distances to galaxies that are over 6 billion light years away.

"There are not many things in our daily lives that we know to 1-percent accuracy," said David Schlegel, a physicist at Lawrence Berkeley National Laboratory and the principal investigator of BOSS. "I now know the size of the universe better than I know the size of my house."

Scientists now confirm that there is a high probability that the universe harbours an abundance of habitable planets.

NASA’s Kepler telescope has provided information to indicate that one in every five sun-like stars is orbited by planets comparable to Earth. In broad terms, this means that there could be billions of planets capable of supporting life in our Milky Way galaxy alone. The findings were published recently in the Proceedings of the National Academy of Sciences and aired at a special news conference in California.

Voyager I was launched 36 years ago and it speeds through space at the rate of about 38,000 miles an hour. As it passes the outer limits of the solar system, it seems to be entering a bizarre and mysterious region more than 11 billion miles from Earth that scientists are struggling to make sense of.

NASA says," It’s a region where the fierce solar winds have all but vanished and pieces of atoms blasted across the galaxy by ancient supernovae drift into the solar system." The NASA probe is causing scientists to question some long-standing theories on the nature of our solar system and life beyond its cold dark edge dubbed the "magnetic highway."

We know people can do it, but can PLANTS do it? This is necessary to know if we want to eventually create living space environments, in which people can spend the many years it might take to travel to distant stars and planets.

Researchers have found that changes in gravity affect the reproductive process in plants. Gravity modulates traffic on the intracellular "highways" that ensure the growth and functionality of the male reproductive organ in plants, the pollen tube.
