How About...meteors?

What's happening?

A little bit of panic and chaos was caused due to the meteor shower received by Chelyabinsk

How About...Russian meteor? Feb 15th?

How About...ESA TV?

ESA TV 

ESA tv Live  is here!! you may...

How About...our Sun Feb. 2. 13- Feb.12.13

How About...Printing in the Moon?

Seems like 3d-Printing is the new trend for next generation of Moon-walkers

"Industrial partners including renowned architects Foster + Partners have joined with ESA to test the feasibility of 3D printing using lunar soil." (ESA)

How About...Valentine's Asteroid?

THIS ASTEROID WILL NOT HIT EARTH

what's so amazing is how near its orbit will allow this asteroid to flyby.

I could write a thousand words, but I prefer to show you these awesome details brought to you by NASA:

How About...Stars' Fertility?

Stars seem to have a longer fertile life

Recent studies conducted by NASA and ESA scientists, with the help of Herschel space observatory, reveal that stars may have a longer fertile life than previously calculated.

Nuestra Luna, Júpiter y sus 4 lunas

Este artículo  lo he escrito especialmente para mi Abuelito Sigifredo Rodríguez Godina.

Esta es una de las fotografías que tomé el día de hoy con mi telescopio y mi celular Nokia. Así mismo  logré capturar a Júpiter y sus cuatro lunas.

El 21 de Diciembre del 2012...

¿El fin de?

La fecha "del fin del mundo" se acerca cada vez más y más...pero ¿en realidad se va a acabar el mundo? ¿por qué todos dicen eso?

How About...December 21 2012?

End of...?

The date is getting nearer and nearer, many people may star freaking out but, should we really be scared of that?

How About...NASA TV LIVE!

Hola estimados Lectores! sólo quería recordarles que aun tenemos la televisión de la NASA en vivo!

pueden observar lo que los astronautas en la estación espacial internacional están viendo justo ahorita.

Además lo podrán ver en HD alta definición.

en esta publicación podrán ver la tv, pero ademas estará siempre disponible para ustedes en la parte derecha de este artículo.



Hello dear Readers, I just wanted to remind you that we still got NASA TV live!


you can watch what astronauts are experiencing at the moment live! from space  HD!


you can find NASA TV LIVE at the right part of the article---->


still I'm publishing this for you.







Enjoy!



Special thanks to NASA.

How About...Space Fossils

My first video in spanish, I hope you enjoy it .

Yes your read right, universe fossils. Most of you might have heard about the fact that the star upon which you just made a wish is dead. The reason why this fact is so true, is because even though a star died thousands of years ago, its light keeps traveling in space. Thanks to this phenomenon, we get to know more about the past. That’s why these remnants have been described as universe or space fossils.

Now what NASA scientists scientist Marco Ajello a postdoctoral researcher at the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University in California and the Space Sciences Laboratory at the University of California at Berkeley.and his investigation team have done, is measure the amount of space fossils. This means they have measured the exact amount of starlight that has ever existed since the universes origins.

This fossil starlight named by scientists as extragalactic background light (EBL) acts as a cosmic fog.

But how do they do it? Well Scientists used Fermi’s Large area telescope or LAT, to analyze the gamma rays from a 150 blazars, that means galaxies powered by blackholes, and found out energies of around 3 billion electron volts, that means at least 1 billion times the energy of visible light

Blazars are galaxies powered by supermassive blackholes which are fed from matter. When matter is swallowed by this supermassive blackhole, it collides with other particles causing gamma rays and many other rays from the light spectrum (i.e. x-rays ) to be ejected violently in opposite directions, just like this image below.

this is an artist's concept of a quasar, also part of the family of blazars

With these large amount of energy ejected as light (gamma rays) scientists can measure the amount of space fossils and know more about our origins. 

When scientist compare the gamma rays emitted from 150 different blazars and that that has been received they of course find some difference. The reason is because when gamma rays collide against these  "space fossils" or EBL, starlight "cosmic fog", transform into something else. 

image captured by the Fermi's Large Area Telescope. Green dots are blazars, orange line milky way. Image from NASA.

Yes, when gamma rays hit the EBL, they become electrons and its antimatter part called positrons. We no longer have gamma rays but, two different particles. Since not all the gamma rays hit againts cosmic fog, we still receive certain amount of them. 

Comparing these results and measurements scientists have been able to measure not only the amount of cosmic fossils or cosmic fog, but also space's density. 

What scientists have concluded is that the distance between two different stars is around 4,150 light-years.  For you to have a better idea of how much a light-year is you need to know first the distance between the Earth and the Sun.

The distance between the Earth and the Sun is 150 million km. This  distance is commonly known as an Astronomical Unit or AU. Now returning to the light-year, one light year equals 63,000 Astronomical Units. Can you imagine that?

For you to be able to travel only 1 light-year you would need to travel the distance between the sun and the Earth 63,000 times! now imagine 4,150 light years!

More investigations like this one could lead us to more precise data about our origins and the universe first stars that lit their light for the first time.

Thanks for reading.

We have lost one key person, the inspiration of this blog. Requiescat in Pace.

 

I hope this is only a giant leap you've taken into other time-space dimension. I hope we meet later.  

How About...a Storm?

A Solar Storm is expected to hit Earth

Goddard Space Weather Lab detected a Big Sunpot AR1520 that unleashed an X1.4-class solar flare on July 12th.

How About...A fifth moon?

One more moon unveiled

NASA's team of astronomers, with the help of Hubble Space Telescope discovered another Moon orbiting the now Dwarf Planet Pluto.

How About...Earth-size Planets Beyond Our Solar System

Kepler Telescope

Well ladies and gentlemen, here I present you, what I would call the year's greatest discovery.

How About...Torus Clouds?

Water present at Saturn's Atmosphere

This artist's concept shows a glowing patch of ultraviolet light near Saturn's north pole that occurs at the "footprint" of the magnetic connection between Saturn and its moon Enceladus.(Image credit: NASA/JPL/JHUAPL/University of Colorado/Central Arizona College/SSI) I'll talk about this later.

ESA (European Space Agency) with the help of Herschel Space Observatory found out a donut-shaped cloud encircling Saturn.

How About...Blazing Jets?

Astronomers have found that there are several fluctuations on blazing jets at Blackholes.

Nowadays Blackholes are nothing new to you (or at least they shouldn't...and if you have not heard about them, wait for my article: How About...Blackholes? , in which you'll know more information about them)  but now astronomers have seen that they might behave a little bit different than thought.

How About...Stars?

Herschel Telescope has changed what we know about new born galaxies.

Remember that previous article about Filaments, called Sonic Boom? (Well if you haven't read it yet, I'd recommend you to read it. ) Well, now Herschel brought us even better news about how galaxies form.
