In physics, radiation is a process in which energetic particles or energetic waves travel through a vacuum, or through matter-containing media that are not required for their propagation. Waves of a mass filled medium itself, such as water waves or sound waves, are usually not considered to be forms of "radiation" in this sense.
Eccentric millionaire Dennis Tito – better known for being the first tourist astronaut in space – announced late last month that he has set-up a manned mission to Mars called Inspiration Mars set to put the first man and woman into Martian orbit by 2018. As audacious as the plan might seem, Tito claims that [...]
A ring of radiation that scientists knew nothing about fleetingly surrounded our planet last year, before being blown away by a powerful interplanetary shock, researchers say. Astronomic intuition Usually, whenever NASA launches a spacecraft, they wait weeks or even months to finely tune all its instruments. It’s a rite of passage that all shuttles (and [...]
In a new monumental find, Curiosity data readings suggest that radiation levels on the surface of Mars are very much similar to those in sub-orbital Earth. This means that astronauts or marsonauts can indeed set foot on the red planet, albeit for a limited amount of time. The findings came after the Curiosity rover, still [...]
Using a new X-raying technique and device, based on synchrotron radiation, scientists have been able to map the pigmentation of creatures dead for million of years just by reading the traces metals in fossils left. “Every once in a while we are lucky enough to discover something new, something that nobody has ever seen before,” [...]
We previously reported about an incredible gamma ray burst triggered by a black hole, so powerful that nothing like this was observed before, or even dimmed possible. A recently published paper in the journal Science sheds more light on the subject. A typical gamma ray burst commonly occurs when massive stars explode due to collisions [...]
We’ve all seen at least one movie in which our planet is destroyed, but most of them were quite repetitive and kind of uninteresting. Our planet deserves so much more! Black holes Well, it seems the more we understand things about black holes, the more we find out things we don’t know, and the more [...]
