According to experts, exoplanets can be surprisingly common in our galaxy the milky way, but their number is likely higher than the number of stars. According to the calculations of astronomers, on average, each star has around him 1,6 planets, given that according to current estimates in the milky way there are about 100 billion stars, we can say that in our galaxy there are 160 billion planets.

Scientists were able to do something incredible: they were able to cool the substance is lower than the temperature, which until now was considered as an absolute minimum. In most modern textbooks on physics absolute zero on the Kelvin or minus 273,15 degrees Celsius is the lowest possible temperature, as it is the lightest element, hydrogen - completely loses its mobility, that is, figuratively speaking, freezes.

Simultaneous formation of the star HD 142527, located in the constellation of the Wolf and the surrounding planets recorded ALMA telescope that helped scientists later to find out how matter protoplanetary disk is moved to the star, despite the great distance between them, reported in an article published in the current issue of the journal Nature.

Senseless dreams does not happen. 90% of our dreams reflect anxieties, desires and stress in our lives. Dreams are trying our subconscious to find answers to the questions that it may not get during wakefulness.

American scientists from NASA showed us a photo of the Central peak in the lunar crater Tycho.

Even if the interplanetary flights would be a reality, scientists often say that the human body from a purely biological point of view await increasing threats. One of the main dangers experts call hard cosmic radiation. On other planets, for example the same Mars, this radiation is such that it significantly accelerate the onset of Alzheimer's disease.

Electric networks and systems-GPS on Earth, as the observations of researchers who become from year to year more sensitive and vulnerable to solar activity.

Laser emitter with unattainable for today capacity of 202 terawatt could destroy an asteroid with a diameter of 7.5 kilometers, caused the extinction of the dinosaurs 65 million years ago, which casts doubt on all such projects "asteroid protection", state physics in an article published in journal of Physics Special Topics.

The end of the world according to the Mayan calendar on December 21, never happened. But in the Network walks schedule Apocalypses for each year up to 2020.

As from non-living chemical elements appeared living organisms is an old issue facing scientists. But in a study published in the journal Physical Biology, researchers from Santa Fe offers quite plausible and integral explanation.

Let's see what programs and space, and suborbital launches planned for 2013.

The engineer and programmer Kevin Jill from the USA demonstrated how from space could look like Mars in the past, if it existed on the planet life. With the results of the simulation can be found in the blog engineer, and brief comments to them passes the Universe Today.

In 2013 it is proved the existence of life on another planet, which is most similar to Earth. The opening will transform humanity about their place in the Universe.

The team of scientists titled finally brought resistant cells that are able to fight tumors.

According universetoday, a team of researchers from the medical center of the University of Rochester (URMC) in new York announced the results of their research. Long-term presence of astronavtov in space, for example, during the flight to Mars, can lead to health problems because of galakticheskogo radiation. In particular, to the degeneration of the brain, and perhaps even the onset of Alzheimer's disease.
