A 2013 space: the six more important events
2013 has been a very eventful year in space. Discoveries and milestones expected in some cases for decades have been achieved during the past year. Here are the main innovations of 2013.
1. Voyager 1 is released from the boundaries of the solar system
After 36 years of waiting, the Voyager was able to cross the boundaries of the solar system, becoming the first ever human vehicle to have crossed this threshold and to have achieved interstellar space.
2. Extraterrestrial neutrinos found in Antarctica
To reveal for the first time was the IceCube, a sort of large “camera” underground into the icy depths of the South Pole has found the first evidence of cosmic rays from outside the solar system. Of the billions of neutrinos passing through one square centimeter of the Earth every second, only a few actually interact with matter. Those identified by IceCube are produced by cosmic sources are still unknown.
3. In the past, Mars may have hosted life
The painstaking work of Curiosity rover on Mars may have provided evidence of the past presence of life on Mars. In the past, the planet could accommodate microbes. Within a rock sample collected by the robot at NASA, scientists have identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon, some of the basic chemical ingredients for life.
4. Discovered Earth’s Twin, the exoplanet Kepler- 78b
This celestial body, Kepler- 78b revolves around the parent star Kepler- 78 at a high speed. Its year lasts 8.5 hours in fact, compared to 365 days on Earth. But size is very similar to Earth. What makes it different from us is that its orbit is very close. Do not delude ourselves. On this planet, life is impossible because the distance from its star is slightly more than one million kilometers.
5. The explosion of the meteor in Chelyabinsk
On February 15, in Russia a meteorite crashed near the city of Chelyabinsk. The fragments caused damage and caused injuries to some people. This has raised concerns about the potential threats from space.
6. Ison, the comet of the century, destroyed by the Sun
The whole world held its breath when Ison was been waited for over a year, but it was not the comet of the century. After having managed to survive the perihelion, the ball of ice and dust had gradually faded, disappointing the expectations of the fans. The Sun was stronger than her.
