Monthly Stargazing Calendar for October 2011
This month we were expecting to see a close approach of the comet Elenin. Unfortunately, the comet has recently lost in brightness and it seems that it is breaking up. Even these news haven't stopped all that doomsday nonsense in the blogosphere about this comet crashing into the Earth…
“Mystic Mountain” in the Carina Nebula – Astronomy Picture of the Week
This close up on the Carina nebula looks like the fantasy "Mystic Mountain" from Tolkien's "The Lord of the Rings". The image was taken on Feb. 1-2, 2010 by NASA's Hubble Space Telescope in celebration of the 20th anniversary of Hubble's launch and deployment into an orbit around the Earth.
Tatooine-Like Planet Discovered Orbiting Two Suns
An exoplanet that orbits around two stars, known as a circumbinary planet, has recently been discovered by astronomers using the Kepler space telescope. The planet dubbed Kepler-16b has been compared to the planet Tatooine from Star Wars, due to the fact that it has two Suns in its sky.
Monthly Stargazing Calendar for September 2011
This month you can witness a supernova with just binoculars or a small telescope. The supernova is called SN 2011fe and has been discovered by astronomers on August 24 within hours of its explosion. It is located within the Messier 101 galaxy 23 million light-years away in the constellation of Ursa Major.
Astronomy Picture of the Week – Starburst Galaxy NGC 1569
This image of a dwarf galaxy called NGC 1569 was taken by NASA's Hubble Space Telescope. It is of one of the most active galaxies in our local neighborhood. NGC 1569 gives birth to stars at a rate that is 100 times faster than the rate observed in our Milky Way Galaxy.
Millennium Simulation – The Gigantic Size of our Universe [Video]
The Millennium Simulation, also known as the Millennium Run, is a giant simulation of the whole known Universe. It clearly shows the distribution of clusters...
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.
Earth’s First Trojan Asteroid discovered by NASA’s WISE
NASA's WISE mission discovered asteroid 2010 TK7, an Earth Trojan, in a stable orbit around a Lagrangian point, possibly a future space destination.
