Família do réptil

Citando:
"they probably originated just before the “Great Dying” – a catastrophic mass extinction event 252m years ago when more than 90% of marine creature and 70% of land vertebrates died. That, Bernardi said, overturns current theories that they arose after the disaster, and reveals that many different species appeared in the wake of the catastrophe due to factors such as a lack of competitors. “It is like the other side of extinctions,” he said. “Squamates, for example, were actually there before the extinction, they went through [it] in some way, and they took the opportunities that opened up just after the extinction,” he said."

Artigos da NASA disponíveis

https://www.sciencealert.com/all-nasa-science-research-available-free-online-pubspace
Citando:
"There's something very special about all the awesome research funded by NASA - it's accessible, for free, to everyone.

It was a particularly special moment when NASA announced this shift to open access back in 2016. Not only would all published research funded by the space agency be available at no cost, the agency also launched a public web portal to make it easy for anybody to gain access."

Estrelas desde cedo

https://zap.aeiou.pt/estrelas-nasceram-big-bang-203017

Citando:
"Para além do brilho do oxigénio capturado pelo ALMA, um sinal ainda mais fraco de emissão de hidrogénio foi igualmente detetado pelo VLT do ESO. A distância à galáxia determinada a partir desta observação é consistente com a distância determinada a partir da observação de oxigénio, o que faz com que MACS1149-JD1 seja a galáxia mais distante observada, com uma medição de distância precisa, e a galáxia mais distante alguma vez observada pelo ALMA ou pelo VLT.

“Estamos a ver esta galáxia quando o Universo tinha apenas 500 milhões de anos de idade e, no entanto, este objeto apresenta já uma população de estrelas bastante madura”"

Galilleo e o Brexit

https://www.ft.com/content/8294b680-4d48-11e8-8a8e-22951a2d8493

Citando:
"It comes after the EU offered a contract to CGI UK to transfer to Thales of France its expertise in the cryptography protecting Galileo’s highly secure navigation arrangement for government users, called the Public Regulated Service.

CGI is the largest supplier of security systems for the Galileo programme but, under current rules, the public regulated service can be accessed only by EU member states.


British officials admit that they cannot legally prevent CGI UK from selling its technology to the EU. However, London was looking at what work could be offered to keep the expertise in Britain if CGI decided not to take the contract with the bloc involving Thales. This could include involvement in the proposed domestic satellite navigation system."
