I want to travel to space

Unfortunately if you want to travel to space today, it will cost you $200,000 USD per person. I guess I’ll have to wait for the price to go down, I just hope it doesn’t take very long.

Meanwhile I can almost see what it’s like to be there with the help of these sites with downloadable applications:

GOOGLE EARTH: http://earth.google.com/Google Earth

With Google Earth you can fly to any part of the Earth to see satelite images, maps, buildings in 3D… from galaxies in space to explore Mars in 3D.

CELESTIA: http://www.shatters.net/celestia/Celestia

It is a free space simulation that lets you explore our universe in three dimensions. You can travel throughout the Solar System, to more than 100,000 stars or even beyond our galaxy.

Did you know that astronauts that have been living in space…

  1. suffer from space sickness, nausea, headaches and difficulty to locate their own limbs? This is space travelcaused by the confusing information that gets to their inner ear where balance is controlled.
  2. snore less when they sleep in outer space than when they slept on Earth?
  3. they season their food with liquid salt and pepper? To prevent the grains reach their nose and obstruct their vents.
  4. when they get back to Earth they report difficulty to move their arms and legs? This is another reason why they call it the “second birth”.
  5. they claim they can’t get used to falling objects when they drop them? Ha.
  6. 18 people have died in space missions, but never in space, it has always been leaving the Earth or returning back.

Raise your hand if you want to eat powder food every day and sleep “standing up” inside a sleeping bag… anyone?, another reason why we should thank the astronauts.

These astronauts weren’t taught that they shouldn’t play with their food, I think that adults become kids again in space Ü.

GOOGLE EARTH: http://earth.google.com/Google Earth

Google Earth te permite volar a cualquier parte de la Tierra para ver imágenes de satélite, mapas, relieves, edificios en 3D… desde galaxias del espacio exterior hasta explorar Marte en 3D. Podrás explorar un rico contenido geográfico, guardar los lugares que visites y compartirlos con otras personas.

CELESTIA: http://www.shatters.net/celestia/

Simulación espacial que te permite explorar el universo en tres dimensiones. Puedes viajar a través Celestiadel Sistema Solar, a cualquiera de más de 100,ooo estrellas o incluso más allá de nuestra galaxia.

Para obtener más detalles de estas aplicaciones, puedes acceder a este número de la revista virtual Piensa Indigo.

Complementando lo anterior, ¿sabías que los astronautas que viven en el espacio…

Cosmic Calendar

I have already mentioned in previous posts that I am a HUGE Carl Sagan fan, not just because of his expertise in several science areas, but also because he loved to share everything he knew with calendariopeople and he did it in a way that was really easy to understand for everyone.

One of my favorite explanations made by him is the cosmic calendar and it is precisely the topic of this post.

The main purpose of the cosmic calendar is to represent the history of the universe in a calendar year (from January to December) since the Big Bang till today. The object is to represent the most important events in a timeline to have a better perspective and understanding of what happened billions of years ago.

Having this in mind, this is how the cosmic calendar looks like:

JANUARY

  • January 1st: The Big Bang. The universe is formed.

FEBRUARY

MARCH

APRIL

MAY

  • May 1st: Origin of the Milky Way.

JUNE

  • Planetary systems are formed.

JULY

  • Planetary systems are formed.

AUGUST

  • Planetary systems are formed.

SEPTEMBER

  • September 9th: Origin of the Solar System.
  • September 14th: Formation of the Earth.
  • September 25th: Origin of life on Earth.

OCTOBER

  • October 2nd: Formation of the oldest known rocks.
  • October 9th: Oldest fossils.

NOVEMBER

  • November 1st: Sexual differentiation.
  • November 12th: Oldest photosynthetical plants known.
  • November 15th: Eukaryotes appear (first cells with a nucleus).

DECEMBER

  • December 1st: Formation of an atmosphere filled with oxygen on Earth.
  • December 18th: First plancton.
  • December 19th: First fish. Vertebrates appear.
  • December 21st: First insects.
  • December 23rd: Reptiles appear.
  • December 24th: First dinosaurs.
  • December 26th: Mammals appear.
  • December 28th: First flowers. Dinosaurs become extinct.
  • December 29th: First primates.
  • December 31st: First human appears.

_________________

Temporary Scale:

Ω A month represents 1.25 billion years.
Ω A day represents 40 million years.
Ω A second represents 500 years.

_________________

When I first read this data I found myself in a universal context in which I had never been.

On the next post I’ll give the detail of what happened on December 31st of the cosmic calendar.

If you want further information about the topic you can find it in the famous Carl Sagan’s TV series “Cosmos” or in his book  “The Dragons of Eden.” In youtube you can also find related content.

Mimas: Saturn Moon

This is Mimas and it’s one of Saturn’s moons.

Mimas

Whatever hit this moon almost destroys it. It’s big crater is called Herschel, after his discoverer Sir William Herschel in 1789.

It has a 130 kilometer diameter and is mainly made up of rocks and ice water.

Death Star

This moon reminds me to the Star Wars’ Death Star, there’s no doubt of its resemblace.

Do you think George Lucas might have been inspired by this satellite to create the space station from Eposode VI?

Online Planetarium

Going through pages and pages in Stumble Upon (most of them are worth it) I found this wonder:

Neave Planetarium

The Neave Planetarium is an online planetarium with which we can know more about the stars, planets and constellations that are found in the sky at any given moment and which we can see with the naked eye.

It’s as simple as choosing our location and the time in the application, and going out to see the stars.

When you want to know something about a given star or planet, locate it on the online planetarium and click it so that information can be displayed about it like its name, its constellation (if it is a star), its brilliance (magnitude) and its distance from Earth.

An excellent tool for those who love to look up and admire what’s in the sky.

Searching for LIFE

Aeronave Kepler

This APOD, shows the trail left by the Delta II rocket which is taking the Kepler sapaceship into space. This picture was taken in Florida 3 miles from Cape Canaveral.

Kepler’s mission is to search earth-like planets with a temperature capable of keeping liquid water in its surface, as we know, an essential element for LIFE.

We’ll be surprised really soon.

The Other Europe

Europa

It is not the old continent, it’s one of Jupiter’s moons. This APOD was taken by the Galileo spaceship during its mission while orbiting Jupiter from 1995 to 2003.

Europa is almost the same size as the Moon, it is only smoother and has less highlands and less craters than our natural satellite.

There’s evidence that underneath its ice surface, liquid oceans may exist. If the ice layer is thin enough, a mission has been planned to find out if there’s life in these oceans.

About Zodiac Signs

Maybe you love to ask people you just met: “What’s your zodiac sign?” And maybe your perception towards that person changes depending on which sign he tells you he is and what you think you know about that particular zodiac sign.

I am sorry to disappoint you. Zodiac signs don’t have anything to do with your life and probably you think your sign is one when it’s actually another. Why?

Well, because your zodiac sign depends on the position of the Sun in relation with the constellations and how they appeared 2,200 years ago!! And that position is NOT the same as TODAY.

Astronomy and Astrology are two very different disciplines. Astrology may have its bases on science but the idea of  being influenced and determined by the alignment of the stars in the universe is a completely different thing…

If you still doubt and believe that the characterisitics of your zodiac sign strongly relate to you or you can’t get out of your house without reading your horoscope first, I recommend this video from Carl Sagan, mmmaaasssttteeerrr, let’s see if he can change your mind.

If on the other hand the zodiac signs don’t influence you in any way, I also suggest you to see it.

On the table below you can look up for your real zodiac sign.

CAPRICORN: Jan 20 to Feb 16 LEO: Aug 10 to Sep 16
AQUARIUS: Feb 16 to Mar 11 VIRGO: Sep 16 to Oct 30
PISCES: Mar 11 to Apr 18 LIBRA: Oct 30 to Nov 23
ARIES: Apr 18 to May 13 SCORPIO: Nov 23 to Nov 29
TAURUS: May 13 to Jun 21 OPHIUCHUS*: Nov 29 to Dec 17
GEMINI: Jun 21 to Jul 20 SAGITTARIUS: Dec 17 to Jan 20
CANCER: Jul 20 to Aug 10
* This sign doesn’t exist in the traditional zodiac.

Did you know…

… that the moon used to be much more closer than it is now?

Yes, a billion years ago, the moon had a smaller orbit so it needed only 20 days to go around the earth and complete a month.

At that time a day only lasted 18 hours!

The moon keeps getting away, 1.6 inches each year.

The Earth’s rotation is changing too. It is getting slower extending our days.

In a distant future, a day will last 960 hours. Not bad for those who need more hours during the day.

Pretty, pretty

NGC 7331

This is the NGC 7331 galaxy, and is about 50 million light years away. It is found in the Pegaso constellation and was discovered by William Herschel in 1784.

It has been considered similar to ours, the Milky Way, because of  its mass, number of stars and rhythm on stellar formation. But it has been proved that this galaxy is much more brilliant and massive than ours.

It is really possible there is life in this galaxy and in many others… or do you think we’re alone in the universe?
