Acha que dava para astronauta? Experimente os testes da ESA



A ESA não está à procura de astronautas, mas está à procura de voluntários que ajudem a refinar os métodos para testar candidatos.
Assim, a ESA abriu ao público em geral uma versão inicial de um teste ( que pode ser experimentado aqui) para candidatos a astronautas que serve para avaliar essa capacidade de orientação e manipulação tridimensional de objetos. "Neste momento a EPA não está a selecionar astronautas, mas desenvolver testes para o fazer leva tempo e precisa de ser bem feito", disse Frank De Winne, dirigente do centro de astronautas da ESA.

The competition is open to teams of at least 5 high-school students aged 16 and up and at least one adult supervisor.
Register now for this unique chance to become a scientist at CERN. Read more.

Could You Live on Planet Nine?


Surely you have heard all of the news about Planet Nine? If not, here are a few of the major points:
  • There are many objects in the Kuiper belt (the stuff past Pluto) that have orbits around the Sun but are sort of bunched to one side of the solar system.
  • The motion of these Kuiper belt objects could be explained by the gravitational influence of an unknown planet—Planet Nine. Read more.
e mythical "Planet X" may actually be real, and scientists are calling it "Planet Nine."
Astronomers have found evidence for a planet 10 times more massive than Earth in the far outer solar system, orbiting about 20 times farther from the sun than distant Neptune does.

New Metamaterial Transmits Light With No Energy Loss



Very soon we might be able to say good riddance to the overheating laptops, phones and tablets that we deal with every day. Electrons carry information around circuits but lose energy as heat during transmission. Electrons are the best thing we have right now for computing, but in the near future we could wave goodbye to electronics and welcome photon, or light, communication that will be both faster and cooler. There are still few hurdles before we can get this technology in every home and every pocket, but one of its limitations was just solved by the development of a new metamaterial.
