Lanzamiento de CLASP (NASA)

Instrumento CLASP (Chromospheric Lyman-Alpha SpectroPolarimeter), lanzado el 3 de septiembre de 2015 en un cohete suborbital de la NASA desde el Campo de Misiles de Arenas Blancas (Nuevo México, Estados Unidos). Midió por primera vez la polarización de la radiación ultravioleta del Sol en las líneas Lyman-alfa del hidrógeno y del Si III a 1206 Angstromsm, que proporciona información sobre el campo magnético y geometría del plasma en la enigmática región de transición entre la cromosfera y corona del Sol. El instrumento realizó las observaciones por encima de 150 km de altura, donde dicha radiación ultravioleta comienza a ser medible, mientras ascendía hasta 300 kilómetros de altura siguiendo una trayectoria parabólica. Los cuatro centros de investigación responsables de esta misión son NAOJ, NASA/MSFC, IAS y el IAC.

How can Stars Billions of Light Years Away Appear to Adam & Eve?

Publicado el 7 ene. 2014

Dr. Humphreys provides a fascinating cosmology for how stars could appear to Adam and Eve.

For biblical creationists this seems to be completely contrary to the Bible's Young Earth perspective. Since some stars are billions of light years away, it seems foolish to believe that the universe is only 6.000 years old. This is a problem for biblical creationists and it is a huge public relations problem since it is easy for moderately educated people to understand the problem and what it means in regard to the age of the Universe.

In recent years creation cosmologists have been thinking about how to solve the problem. Several of them have come up with testable hypotheses. Dr. Humphreys has a scientifically realistic solution to the problem. His PhD is in physics from Louisiana State University in 1972. He has worked for General Electric and Sandia National Laboratories in nuclear physics.

Watch this video to learn about Einstein's theory of relativity, atomic clocks, an event horizon, black holes and red shift. Through this interview you will learn how modern understanding of physics helps us understand that light from the stars was indeed available for Adam and Eve to see.

How Big is God? - Diego Rodgriguez

How Big Is God is an exciting multimedia presentation featuring audio and visual effects, computer animation, and a laser stars display. It will take you on a fascinating journey exploring the size of the Earth, Solar System, Milky Way Galaxy, and ultimately the entire universe! You may never be the same. This presentation has been widely received at Homeschooling Conventions, Christian Camps, and churches by people of all ages.
This video file is a 60 minute seminar by Diego Rodriquez that was recorded during the Seattle Creation Conference ( http://nwcreation.net/conference ), October 2009.

Black Hole Meltdown in the Galactic Center

Black hole extravaganza in 1080p. From ESO-Cast. Not long ago, watching something being ripped apart as it falls towards a giant black hole would be science fiction. This is now reality.

Observers under dark skies, far from the bright city lights, can marvel at the splendor of the Milky Way, arching in an imposing band across the sky. Zooming in towards the center of our galaxy, about 25000 light years away, you can see that it is composed of myriads of stars.
This is a pretty impressive sight, but much is hidden from view by interstellar dust, and astronomers need to look using a different wavelength, the infrared, that can penetrate the dust clouds. With large telescopes, astronomers can then see in detail the swarm of stars circling the supermassive black hole, in the same way that the Earth orbits the Sun.

The Galactic Center harbors the closest supermassive black hole known, and the one that is also the largest in terms of its angular diameter on the sky, making it the... more

Series - El Universo - Super Novas

Las supernovas ocurren cuando una estrella consume todo el hidrógeno. A continuación, comienza la expansión y la destrucción de planetas whaever que están en órbita, en caso de que la estrella es un Sol en el sistema solar. Esta serie tiene la intención de explicar claramente lo que sucede a una estrella cuando pasa a través de ese curso destructivo. Algunos se convierten en estrellas enanas y otros, posiblemente, a los agujeros negro.
