This image really puts into perspective how unbelievably vast our universe is.
Each of the thousands of dots in this image is an entire galaxy containing billions of stars, revealed in a region of space called the Lockman hole, which allows a clear line of sight out into the distant universe, as seen by the Herschel Space Observatory.
Sadly, Herschel’s time has come to an end. http://bit.ly/ZJ2QdY

A day in the year of the life of the solar system …
While the animation above is pretty sweet, you’ll really want to go play with the interactive version of this solar system simulator.
You can punch in any year, and let the orbits proceed fast or slow. Use it to learn how the planets align (and don’t), how different bodies orbit, or as an excuse to stare at your screen with your mouth open in amazement. You can even click the “Tychonian” button to see what an Earth-centric solar system would look like! Go ahead, punch in any year in the past or future, and see what the solar system looked like on a given day.

Awesome! Awesome! Awesome! See what the solar system looked like on any day!! :D

How the Chinese and the Greeks viewed (pretty much) the same sky.
It’s pretty remarkable how differently two cultures can connect the same dots, don’t you think?
(maps via radical cartography)
This is AMAZING. And wonderful because you can click on the pics to flip between the two and compare.
As someone who’s worked in 2 Planetariums, my brain is almost hard wired to see the Ancient Greek version of things, but wow the Chinese one is so much more in depth! They saw so many things! And much more as markers representing ideas than actual images of things.

One of the most beautiful things I have ever seen. I could stare at this for hours, and I used to work in a planetarium! It never gets old! Most gorgeous, humbling view ever.

Sound of Earth
The Voyager Golden Records are phonograph records which were included aboard both Voyager spacecraft, which were launched in 1977. The Voyager spacecrafts are not heading towards any particular star, but Voyager 1 will be within 1.6 light years of the star AC+79 3888 in the Ophiuchus constellation in about 40,000 years.
The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University. Sagan and his associates assembled 116 images and a variety of natural sounds, such as those made by surf, wind, thunder and animals (including the songs of birds and whales). To this they added musical selections from different cultures and eras, spoken greetings in fifty-five languages, and printed messages from President Jimmy Carter and U.N. Secretary-General Kurt Waldheim.
The collection of images includes many photographs and diagrams both in black and white and color. The first images are of scientific interest, showing mathematical and physical quantities, the solar system and its planets, DNA, and human anatomy and reproduction. Care was taken to include not only pictures of humanity, but also some of animals, insects, plants and landscapes. Images of humanity depict a broad range of cultures. These images show food, architecture, and humans in portraits as well as going about their day to day lives. Many pictures are annotated with one or more indications of scales of time, size, or mass. Some images contain indications of chemical composition. All measures used on the pictures are defined in the first few images using physical references that are likely to be consistent anywhere in the universe.

Los discos de oro de las Voyager son discos de vinilo que se incluyeron a bordo de las dos sondas Voyager, las cuales fueron lanzadas el 1977. Las sondas no se dirigen a ninguna estrella en particular, pero el Voyager 1 estará a 1.6 años luz de la estrella AC+79 3888 en la constelación Ofiuco dentro de 40.000 años
Este disco fue ideado por un comité científico de la NASA presidido por el astrónomo Carl Sagan. Contiene una selección de hora y media de duración de música proveniente de varias partes y culturas del mundo, saludos en 55 idiomas humanos, un saludo del presidente Jimmy Carter y del entonces Secretario General de las Naciones Unidas Kurt Waldheim y el ensayo Sonidos de la Tierra, que es una mezcla de sonidos característicos del planeta. También contiene 115 imágenes (+1 de calibración) donde se explica en lenguaje científico la localización del Sistema Solar, las unidades de medida que se utilizan, características de la Tierra, el ADN humano y las características del cuerpo y la sociedad humana.
Se presto mucha atención a no solo incluir imágenes de la humanidad, sino también de animales, insectos, plantas y paisajes. Las imágenes de la sociedad humana muestran un amplio rango de culturas. Estas imágenes muestran comida, arquitectura, retratos de personas así como fotografías de su día a día. Muchas fotografías muestran anotaciones que indican escalas de tiempo, tamaño o masa. Algunas día contienen indicaciones de las composiciones químicas. Todas las medidas utilizadas en las fotografías son definidas en las primeras fotografías utilizando las referencias físicas mas básicas con mas probabilidad de ser consistentes alrededor del universo.
