'Murderous' Worlds Exposed in NASA's 'Galaxy of Horrors' Video

This is a video that NASA created to describe some of the exoplanet that have recently been discovered. Do you find them terrifying?









You can also look at these posters created by NASA about some of the places we could explore one day.

Your prehistoric body

Evolution by natural selection is a curious thing. There are lots of interesting vestiges from other species that can be found in our bodies. Even if they serve no function.
Watch the video below. What parts of the body does it NOT mention?

a) arms
b) eyes
c) ears
d) heart
e) skin

What other part of the body does it mention?

A continent of rubbish

We're learning about the Great Pacific Garbage Patch in 2nd Year of Bachillerato. It's a huge sea of plastic in the middle of the Pacific ocean and it causes a lot of environmental damage. It's quite unbelievable how polluted this planet is getting!

As a complement, we have also watched a TED conference by Charles Moore, the man who discovered it and who is fighting to make things better for our oceans. You can choose the language of the subtitles.





You can find more information about Charles Moore and his foundation at http://www.algalita.org/ More on the life of plastic: https://www.youtube.com/watch?v=_6xlNyWPpB8 Finally, here you can see how the patch has increased and evolved through the years.

Are we alone?

Many people wonder whether we are alone in the universe. Josh Worth's visualization 78 coins gives you a compelling argument to believe that well, there are probably other intelligent beings out there.

There is actually a scientific way to calculate how many civilizations are out there. It's called the Drake Equation. We need to look at how many stars there are in the galaxy, how many habitable planets there are, etc. The problem, of course, is that we really don't know what numbers to use to solve it... yet.

You can play with the equation itself at BBC Future.

You may ask yourself, then, could we ever see other alien civilizations? The answer is, unfortunately, no. Or at least, it would be very, very unlikely. The universe is simply too large.

How large? Well, light, which is the fastest thing that exists, needs to travel more than 5 hours just to get to Pluto. It takes only 8 minutes to reach Earth. (Again, you can check out another great visualization by Josh Worth to see just how large, and, well, empty, the Solar System really is).  

And that's just the Solar System. If you wanted to travel to the nearest star, Proxima Centauri, it would take you 4.22 years at the speed of light. It's 39,900,000,000,000 kilometres away! 

Your life on Earth

Have you ever wondered how old you would be in Saturn? How many kilometers have you travelled around the Milky Way? Or how many times has your heart beaten since you were born? This BBC website gives you a lot of interesting information about your place universe. I'm sure a lot of the facts will surprise you!!

How to motivate kids to learn science

(Borrowed from Saturday Morning Breakfast Cereal, a comic blog. I thought it is absolutely right :-) )

A transparent frog!

Hiroshima scientists create transparent frogs ::: Pink Tentacle

The Japanese scientists that have created them claim that transparent frogs will help them observe different processes like cancer or other changes in internal organs. Besides, the frogs will not be harmed.

What do you think? Do you think it is right to experiment with animals in some cases? How about genetically modifying them? What are the advantages and the disadvantages of it? Do you think the creation of these transparent frogs is going to be useful?
