How Planets in Alien Star Systems Stack Up [Infographic]
The following infographic is a comparison of three alien star systems with our own solar system. It shows the distance at which all the known planets orbit around their stars. As of August 10, 2011, 573 extra-solar planets have been identified, but so far the three systems illustrated below are the record holders for having the most planets.
Astronomy Picture of the Week – Nebula in the Large Magellanic Cloud
This composite image of the nebula near the star cluster NGC 2074 was taken by NASA's Hubble Space Telescope on August 10, 2008, in commemoration of completing its 100,000th orbit in its 18th year since the beginning of the mission.
Planets Viewed From Earth as if They Were at the Distance of the Moon [Video]
This amazing video shows how the planets of the solar system would look if viewed from Earth as if they were orbiting around our planet at the distance of the Moon. Jupiter would nearly completely fill the sky. This video is of course not implying that something like this could happen. It merely compares the sizes of the planets and our moon in a quite original way. It also makes us realize how small the Earth really is compared to the gas giants. When a duplicate Earth is shown in the sky, it’s actually how large our Earth really looks from the Moon. That’s what the Apollo astronauts witnessed during…
Monthly Stargazing Calendar for August 2011
This month on the 12 and 13 the Perseids Meteor Shower will peak. It is one of the best meteor showers to observe because it can produce up to 60 meteors per hour at the peak. You may also be able to see some meteors any time from July 23 to August 22.
Astronomy Picture of the Week – Hubble Finds Ring of Dark Matter
This composite image of a ghostly ring of dark matter in the galaxy cluster Cl 0024+17 was taken by the NASA/ESA Hubble Space Telescope in November 2004. A false color map is superimposed on a Hubble image of the cluster in order to make the cluster's dark matter distribution more evident.

How China’s First Space Station Will Work [Infographic]
With the future of the International Space Station uncertain, the Chinese have announced their own space station program, instead of joining forces with the other space powers. China's space station will be named "Tiangong" which means "Heavenly Palace" in Mandarin.
Astronomy Picture of the Week – Pandora’s Cluster
This galaxy cluster commonly known as Pandora's Cluster is officially named Abell 2744. As observed by a team of scientists, the cluster has a complex and violent history. The giant galaxy cluster appears to be the result of a simultaneous pile-up of at least four separate, smaller galaxy clusters.
