Mai nou, cercetătorii au descoperit pungi de apă lichidă și în crusta înghețată, la doar 1 kilometru adâncime! Cum? Priviți această imagine cu suprafața satelitului Europa. Vedeți cum ea este brăzdată de crevase? La o privire mai atentă, ele arată ca două linii paralele de tren. Suprinzător, astfel de structuri se găsesc și în Groenlanda, așa cum se vede în această poză.
Cu ajutorul unui radar, cercetătorii au arătat cum, în Groenlanda, ele se formează datorită unor pungi de apă aflate la adâncime. Din acestea scapă apă spre suprafața, care apoi îngheață, se dilată, și împinge în gheață în stânga și în dreapta, formând cele două structuri paralele.
Procesul ar avea loc și pe Europa, trădând existența unor pungi de apă la un kilometru adâncime. Acolo s-ar putea găsi microorganisme, ce sunt astfel mai ușor de găsit decât dacă trebuie să forăm la zeci de kilometri adâncime pentru a ajunge la oceanul subteran.
În 2024 sonda Europa Clipper va pleca spre Europa. Voi ce credeți că va găsi?

Holograme pe care le poți atinge!
#youtubevideos #subscribe Urmareste mai multe #shorts aici
https://www.youtube.com/playlist?list=PLcod69NUBSYiax7w_5cXANwSf5b8I22V0
Bine ați venit în holodeck. Știu, nu vi se pare nimic special. Ați văzut atâtea filme SF cu astfel de holograme că, dacă va arată cineva așa ceva în realitate, nu vă veți mira. Păcat, pentru că nimeni până acum nu a reușit să facă o astfel de hologramă tactilă cât de cât realistă. Motivul este simplu: lumina ce formează holograma are o presiune prea mică pentru a fi simțită de mână. Desigur, dacă se folosesc mănuși speciale, se poate, dar nu asta vrem. Vrem să atingem holograma cu mâna noastră!
Soluția găsită de cercetători este să folosească jeturi de aer, pe care să le trimită către mână, a cărei poziție o determină cu o cameră de luat vederi. Intensitatea jeturilor de aer este corelată cu poziția mâinii în interiorul hologramei, în așa fel încât să simțim jetul ca pe ceva tare dacă holograma arată un perete, sau ca pe ceva ușor dacă holograma reprezintă curgerea unei ape. Echipa universității Glasgow a testat sistemul generând holograma unei mingi de baschetbal. Ei au reușit să atingă mingea virtuală, să o miște și să o învârtă într-un mod realist. Practic, jetul de aer făcea mâna să simtă prezența mingii, iar mișcarea mâinii punea mingea virtuală în mișcare.
Va fi holograma tactilă parte din Multivers? Voi ce credeți?

Water experiments part 2 – olive oil | Cosmic Kiss (In German, English subtitles available)
ESA astronaut Matthias Maurer is currently living and working aboard the International Space Station for his first space mission, Cosmic Kiss. Recently, he experimented with water in microgravity.
In this water experiments video series, Matthias demonstrates the different behavior of water in weightlessness and how this research is applied to life on Earth.In this second clip in the series, Matthias blows air into a floating water sphere and looks at what happens when he tries to mix it with olive oil.
Matthias will live and work in orbit for approximately six months for his Cosmic Kiss mission. During this time, he will conduct and support more than 35 European and numerous other international experiments in microgravity.

Mars confinement tips
In these times of confinement, ESA astronaut support engineer Romain Charles shares nine tips on how to live in isolation – he spent 520 days locked in a mockup spacecraft and is a true expert on the subject.
Mars500 locked six ‘marsonauts’ in a simulated spaceship near Moscow, Russia for 520 days, the time it would take to fly to Mars and back plus 30 days spent exploring its surface. It was the first full-length, high-fidelity simulation of a human mission to our neighbouring planet. The crew went into lockdown on 3 June 2010, and they did not open the hatch until 17 months later on 4 November 2011.
Mars 500 was a success in that it proved that humans can survive the inevitable isolation that is needed for a mission to Mars and back. Psychologically, we can do it!
The crew had their ups and downs, but these were to be expected. In fact, scientists anticipated many more problems, but the crew did very well coping with the monotonous mission, with little variation in food and even a communication delay over 12 minutes one-way.
During their simulated mission, the crew lived in isolation without fresh food, sunlight or fresh air. The participants from Italy, Russia, China and France had no external cues such as the Sun going down at night to remind them when to sleep.
Their bodies are among the most researched in the world. Years of constant monitoring, prodding and taking blood allowed scientists examined how they reacted to the time in confinement with experiments focussing on their bodies, mental states and performance.

Fruit-Power Battery – Sick Science! #080
Read the full experiment at http://www.stevespanglerscience.com/experiment/fruit-power-battery Voltaic batteries of all shapes and sizes are objects that convert chemical energy into electrical energy. You probably use batteries to power your cell phone, iPod, or any number of wireless gadgets. But did you know that you can actually use chemical energy stored within a lemon to power a small LED light? It’s true, and we’ll show you exactly how in the Fruit-Power Battery experiment.

Shrinking Chip Bag – Sick Science! #064
We can’t get our hands on enough stuff to shrink. Faced with the problem of creating tiny chip bags (don’t ask, some things are better left alone), we turned to Steve. “I don’t know. Throw them in the microwave,” was all he had to say. So we tossed a bag in the microwave and now we have this experiment. Is it scientific? Oh you bet your bag of salted potato chips that it’s scientific.
