John Glenn


John Glenn, o primeiro norte-americano a orbitar em torno da Terra, tornou-se símbolo de patriotismo e perseverança. O último sobrevivente dos pioneiros da era do espaço morreu esta quinta-feira. A história dele é uma lenda.

All ESEA training activities are specifically designed for teaching professionals in STEM disciplines (Science, Technology, Engineering, and Mathematics). The common objectives of ESEA training activities are to introduce teachers to implementing inquire based science education, as well as resource based and project-based teaching approaches.
2016 training activities here.

Be a Cassini Scientist for a day



 The 'Cassini Scientist for a Day' competition returns for a 2016/2017 edition. The competition is designed to give the participants a taste of life as a space scientist. Students are invited to submit a 500-word essay explaining their choice of one of three targets imaged by the Cassini spacecraft, in orbit around Saturn, over the past few years.
Be a Cassini Scientist for a day
To enter the competition, school students (10 –18 years old) from participating countries need to find out as much as possible about the beautiful planet Saturn, its fascinating features, and mysterious moons. Students must then choose one of the three targets imaged by Cassini and write an essay to justify their choice to a panel of experts.

The closing date for the competition in these countries is 23:59 CEST, 3 April 2017. More.

Silly putty makes seriously state-of-the-art sensors




Silly putty is more than just child’s play, according to a new paper – it's a key ingredient in a motion sensor precise enough to detect a spider’s tiny footprints.
Conor Boland, a nanophysicist at Trinity College Dublin in Ireland, and colleagues combined the popular children’s play-goo with graphene: single layers of pure carbon atoms bonded in a honeycomb formation. The result, dubbed “G-Putty”, was unveiled in Science.

Scientists are moulding photons into shapes to unlock the secrets of light

Individual particles of light called photons are considered to have no mass, but that hasn't stopped scientists from figuring out to precisely mould them into shapes up to 4 metres (13.1 feet) long.
In testing the ways light interacts with matter, the researchers found that the specific shape of a photon alters its effect on an atom. The discovery not only tells us more about the nature of light, but could also inform the development of the quantum technologies we'll use in the future. More.

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.

Beamline for Schools: be a CERN scientist for a week




Beamline for Schools (BL4S) is a competition for high-school students from around the world to win the chance to create and perform a scientific experiment on a CERN accelerator beamline. 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.
