To Know Her is To Love Her
Estrella de Hollywood durante el día, inventora durante la noche, la revolución de la transmisión de datos inalambricamente no hubiera sido posible sin su invento de ¨espectro disperso¨ que básicamente hace que cuando usas una frecuencia y esta esta ocupada ó con interferencia la señal se ¨salté¨ a otra frecuencia.

Explanation: What’s that next to the Milky Way? An unusual natural rock formation known as Roque Cinchado or Stone Tree found on the Spanish Canary Island of Tenerife. A famous icon, Roque Cinchado is likely a dense plug of cooled volcanic magma that remains after softer surrounding rock eroded away. Majestically, the central band of our Milky Way Galaxy is visible arcing across the right of the above seven image panoramic mosaic taken during the summer of 2010. On the far right is the Teide volcano complete with a lenticular cloud hovering near its peak.
Explanation: It looks like a double comet, but Comet PanSTARRS (C/2011 L4) is just offering skygazers a Messier moment. Outward bound and fading in this starry scene, the well-photographed comet is remarkably similar in brightness to M31, the Andromeda Galaxy. Tracking through northern skies just below the galaxy, the comet was captured as local midnight approached on April 3. Both comet and galaxy were visible to the eye and are immersed in the faint glow of northern lights as our own Milky Way galaxy arcs over a snowy field near Tänndalen, Sweden. Double star cluster h and chi Persei can be spotted along the Milky Way’s arc high above the comet/galaxy pair. Follow the arc to bright Deneb, alpha star of the constellation Cygnus, at the right edge of the frame.
Calvin: If people sat outside and looked at the stars each night, I’ll bet they’d live a lot differently.
Hobbes: How so?
Calvin: Well, when you look into infinity, you realize that there are more important things than what people do all day.
Comet PANSTARRS Just After Sunset

Explanation: Have you seen the comet? As Comet PANSTARRS fades, careful observers — even with unaided eyes — should still be able to find the shedding ice ball on the western horizon just after sunset. Pictured above, Comet PANSTARRS (C/2011 L4) was pointed out from a hilltop last week on First Encounter Beach in Massachusetts, USA. The comet was discovered by — and is named for — the Pan-STARRS astronomical sky survey that discovered it. As the comet now recedes from both the Earth and the Sun, it will remain visible further into the night, although binoculars or a small telescope will soon to be needed to find it.
