"The Hubble Space Telescope is the oldest space telescope in operation, having spent the past twenty-eight years in orbit. Nevertheless, this mission is still hard at work revealing things about our Solar System, neighboring exoplanets, and some of the farthest reaches of the Universe. And every so often, it also captures an image that happens to turn up something interesting and unexpected.

Recently, while conducting a study of Abell 370, a galaxy cluster located approximately four billion light-years away in the constellation Cetus (the Sea Monster), Hubble managed to spot something in foreground. While observing this collection of several hundred galaxiess, the image was photobombed by 22 asteroids whose tails created streaks that looked like background astronomical phenomena."

Diamante e missão japonesa

Citando:
”Uma nave espacial japonesa chegou ao seu alvo, esta madrugada. O aparelho atingiu a pedra espacial Ryugu, depois de ter deixado a Terra em 2014.

A nave Hayabusa 2 tem como missão aproximar-se do objeto espacial e recolher amostras do solo para serem analisados no Japão.

"Em primeiro lugar, vamos estudar as características do solo com muito cuidado. Depois vamos escolher a melhor forma para aterrar", disse Makoto Yoshikawa, um dos responsáveis pelo projeto, em declarações à "BBC".

Um projétil de cobre vai, depois, separar-se da nave, flutuando até à superfície do asteroide. Assim que o projétil esteja completamente separado da nave, uma carga explosiva será detonada, levando-o até à superfície da pedra."

Onda azul no planeta vermelho?

https://www.dn.pt/sociedade/interior/ha-uma-duna-azul-em-marte-9516247.html

Citando:
"No site do Mars Renaissance Orbiter, um orbiter da NASA, a câmara HiRISE que este usa é descrita como "a câmara fotográfica mais poderosa alguma vez enviada para outro planeta". Foi ela que captou a imagem de uma duna azul em Marte, o quarto planeta a contar e conhecido pela cor vermelha das suas rochas e areais

Na verdade, como explicou à CNN Alfred McEwen, diretor do Planetary Image Research Laboratory na Universidade do Arizona, a duna em questão é na verdade cinzenta, mas aparece na imagem de um azul forte. Foi esta a conclusão a que chegaram os cientistas depois de um apurado trabalho de edição das imagens captadas pelo Mars Renaissance Orbiter."

"The Britain-built satellite, named RemoveDEBRIS mission, is one of the world's first attempts to tackle the build-up of dangerous space debris orbiting the Earth, the British space agency said in a statement late on 22 June.

The 100-kg RemoveDebris spacecraft will attempt to capture simulated space debris using a net and a harpoon while also testing advanced cameras and radar systems."

O senhor ex-Microsoft, a NASA e as estimativas erradas?

Citando:
"Nasa’s Wise space telescope [Wide-field Infrared Survey Explorer] measured the asteroids in four different wavelengths in the infrared. My main beef is with how they analysed that data. What I think happened is they made some poor choices of statistical methods. Then, to cover that up, they didn’t publish a lot of the information that would help someone else replicate it. I’m afraid they have both over- and underestimated. The effect changes depending on the size of the asteroid and what it’s made of. The studies were advertised as being accurate to plus or minus 10%. In fact, it is more like 30-35%. That’s if you look overall. If you look at specific subsets some of them are off by more than 100%. It’s kind of a mess."

Ai os neutrinos!

Tão difíceis de encontrar:
https://www.theregister.co.uk/2018/06/04/miniboone_sterile_neturinos/
Citando:
"Particle physics is hard: the experiment which possibly detected sterile neutrinos collected 15 years' worth of data from its commissioning in 2002, but the results have only now reached pre-press publication at arXiv.

And to the non-expert, the results look indeed tiny: over 15 years, MiniBooNE detected a few hundred more electron neutrinos than were predicted in Standard Model theory.

That, however, brought the MiniBooNE team tantalisingly close to a “result” – it's a 4.8 sigma result, when “discovery” demands 5 sigma.

What's going on?

The lack of interaction makes the sterile neutrino hard to detect – so much so that a single 1990s observation by the now-decommissioned Los Alamos National Lab's Liquid Scintillator Neutrino Detector (LANL LSND) has never been replicated."
