Está de moda un email titulado “dos lunas en el cielo”, que habla de los cálculos de un planetario internacional, determinando que para el 27 de agosto del 2009 Marte se verá grande y brillante como la Luna. No es complicado ver qué tan falsa es la noticia, con aritmética básica.

Recuerdo la primera vez que vi a Marte en el telescopio, fue genial ver este planeta, aunque con todo y aumento no dejaba de ser un punto redondo anaranjado en el campo óptico. Ver planetas del sistema solar a través de un telescopio no es una experiencia común para la mayoría de la gente. Además todos estamos acostumbrados a las hermosas y enormes imágenes que nos muestran a diario los medios de masivos y con las cuales construimos nuestros imaginarios. Es entendible pues, que el "ciudadano de a pie" crea en cualquier información que le llegue a su correo. El ejercicio de la divulgación científica es complejo, sobre todo cuando se compite con la desinformación causada por los grandes medios de comunicación.

Gamma-ray bursts (GRB) are the most powerful explosions known in the Universe; most originate in distant galaxies. A large percentage of bursts likely arise from the explosion of stars over 15 times more massive than our Sun. Experts believe that...

TMT will also cost between 1 and 2 billion dollars when all is said and done. This is not quite at the scale of the world’s biggest science projects, like the Large Hadron Collider or the James Webb Space Telescope, but it’s getting there. In fact, TMT and other proposed observatories of this generation may end up being the biggest telescopes on Earth for all time because the funding required to go even larger would more logically be directed towards putting telescopes in orbit.

Adaptive optics is a big part of TMT’s design. It will work both on Mauna Kea and Armazones, but astronomers expect it will work better on Mauna Kea. This is because the upper atmosphere—the part above the boundary layer—is somewhat less turbulent above Mauna Kea than it is above Armazones. Why? According to Racine it’s partly a function of latitude. Because Mauna Kea is nearer the equator it’s relatively unaffected by the jet streams that flow at higher latitutdes both north and south. Armazones’ upper atmosphere is a bit more turbulent in comparison and so somewhat harder for adaptive optics to deal with.

Why and how did the Thirty Meter Telescope project decide to build at Mauna Kea?
GEMS mission to explore the polarized universe - 0 views
-
An exciting new astrophysics mission led by NASA's Goddard Space Flight Center in Greenbelt, Md., will provide a revolutionary window into the universe. Named the Gravity and Extreme Magnetism Small Explorer (GEMS), the satellite will be the first to systematically measure the polarization of cosmic X-ray sources.

A team of scientists from the California Institute of Technology, Princeton, Drexel University, and the Massachusetts Institute of Technology have formed the first professional scientific organization based entirely in virtual worlds. Meta Institute for Computational Astrophysics (MICA) conducts professional seminars and popular lectures, among other events, for its growing membership.

As modern cosmologists rely more and more on the ominous "dark matter" to explain otherwise inexplicable observations, much effort has gone into the detection of this mysterious substance in the last two decades, yet no direct proof could be found that it actually exists. Even if it does exist, dark matter would be unable to reconcile all the current discrepancies between actual measurements and predictions based on theoretical models. Hence the number of physicists questioning the existence of dark matter has been increasing for some time now.
