Mars and Earth were shaped from the same structure blocks


A team of Carnegie investigated hydrogen liquefy in water from the Martian subsurface, and found that Mars was formed from the same structure blocks as the Earth, and the changes in the chemical composition of the planet began to occur in the course of its subsequent evolution. This indicates that the terrestrial planets, including Earth, the same source of water - chondritic meteorites. However, unlike our planet, Mars rocks, which contain volatile components such as water, can be processed deep in the bowels of the planet.

Temperatures worldwide could rise by 4 degrees

If procedures are not taken to stop climate change by the end of this century, temperatures worldwide could rise by 4 degrees. World Bank does not rule out that even if all the nations of the world to meet the commitments to reduce greenhouse gas emissions is likely to happen at a temperature rise of 3 degrees.

Curiosity discovered "something amazing"


Mars rover Curiosity during the analysis of samples of Martian soil found something very interesting, but scientists refuse to say what the rover found - specialists intend to double-check everything again and eliminate errors, according to the American radio station NPR.

"We receive data from the SAM (Sample Analysis at Mars - chemical laboratory aboard the rover) ... and these data seem to be very interesting.

An amateur astronomer rediscovers an asteroid 'lost'


Between September and October 2008 was observed 2008SE85 potentially hazardous asteroid, but has since lost his track. Until now, when a German amateur observer has re-locate it from an ESA station.

Although not a threat to Earth in the short term, the German amateur astronomer Erwin Schwab has ever seen an asteroid labeled 'potentially dangerous'.

The largest dark spot the moon, known as the Ocean of Storms ("Oceanus Procellarum"), has about 3,000 kilometers in diameter and can be a huge scar cosmic impact, researchers say.

Curiosity found on Mars, radiation is not dangerous for humans


Radiation levels on the surface of the Red Planet is equivalent to environment radiation in low Earth orbit, NASA discovered Martian rover Curiosity.

The first measurements of radiation levels - the first held on the surface of another planet - can cheer those who want to see how once on Mars for the first time set foot on the person: Curiosity rover found that people may well spend some time on the surface of the Red Planet.

supernova nuclear blasts produce a paste


When dying stars detonate as supernovae, spread out a shock wave lead the so-called "rebound" - matter and elementary particles are compressed towards the center of the star to achieve the density that come into play in the nuclear force.

In the development of a supernova nuclear particles can create different and often bizarre forms, such as rods, plates or vials and long threads - which gave the name to this phenomenon, associated with the famous Italian pasta. Creating a "paste" because in the dying star DIURNAL two types of forces - the Coulomb revulsion of the same charges and nuclear forces of attraction.
