Angels are believed to be messengers of God in many religious cultures. They guard and guide humans through life. They often appear in literature and art for thousands of years. In art, angels and archangels are usually shown as beautiful and powerful human beings often depicted with wings.
In this collection, I gathered some beautiful angel and archangel artworks and put everything in one place for you. You’ll find here many different positive angels as well as some dark angels that are known as dark messengers, or devils. They also often appear in art so you may see both sides of their nature. So, below you’ll find 57 exquisite angel and archangel artworks! I hope you’ll like them and if so don’t forget to share this collection with your friends!

LookUP, Images and Astrotags
Over time I've added some bells and whistles to help correct spellings ('Did you mean...?') and added thumbnail Digital Sky Survey (DSS) images from Wikisky. One of the things that has bugged me for ages is that solar system objects were never in the DSS thumbnail. That's because the DSS image is a snap-shot at a particular time and Mars, Comet Halley, Vesta etc weren't there at the time. At Science Hack Day I decided to fix this.
With help from Joe Davis, I hacked together a Yahoo YQL request to find the Wikipedia article for the solar system object being searched for. This involved also sending the object type (e.g. 'comet', 'planet', 'moon') otherwise simple searches such as 'Juno' tended to return the wrong article. With that sorted, a second YQL request could be done to extract the image from the infobox in the article. This was also a bit tricky as the infobox sometimes contains a few small images.
Today I properly integrated the thumbnail-image-getter into LookUP. That means that the image details (the image and a link back to where it came from) are also accessible if you prefer your results in XML or JSON formats. That brings me onto more image-based goodness that is possible courtesy of the Royal Observatory Greenwich's Astrotag initiative on Flickr. The ROG are encouraging people to add special tags to their astronomical images to make it easy for machines to find them and do things with them. Here is their video introducing astrotags:

Astrotags are exactly the sort of thing LookUP can benefit from. Tonight I made use of the YQL table created by Jim O'Donnell for astrotags and some nice CSS to make the first 5 returned images look like Polaroid snaps. I quite like the result. - taken from Astronomy Blog (www.strudel.org.uk/blog/astro/)"

Los cinco movimientos de la Tierra
Cuando éramos chicos, en el colegio nos enseñaron cómo pese a que en la antigüedad se creía que la Tierra era plana y el centro del universo, gracias a grandes personajes de la historia, se demostró que la tierra ni era plana, ni era el centro del universo. De hecho, ésta es la que gira en torno al sol, realizando el movimiento conocido como de translación, y mientras gira en torno al sol también gira en torno a sí misma, realizando el movimiento de rotación.
Pero más allá de todo esto, no nos contaron nada más, pese a que sí que lo hay. La Tierra no se mueve únicamente en torno al sol y sobre sí misma, sino que además tiene otros tres movimientos principales adicionales: precesión de los equinoccios, nutación y el bamboleo de Chandler.
I: La Tierra
Además de estos cinco movimientos principales, existen otros movimientos históricamente considerados secundarios como son las variaciones del plano elíptico en el que se describe el movimiento de translación, las variaciones en la excentricidad de la elipse descrita en este movimiento, o los movimientos que realiza la Tierra por estar dentro del Sistema Solar, o por estar dentro de la Vía Láctea.
En Amazings.es dejé una breve descripción sobre cada uno de estos cinco movimientos. No dudéis en echar un vistazo.
