Preparing For Launch: An Update on JWST
Move over, Hubble! NASA's currently in the middle of building Hubble's successor as we speak. The James Webb Space Telescope (JWTS) will help astronomers understand the history of the universe using infrared technology and a mirror coated in 24-karat gold! To discover how these function, read on, and prepare to launch!
Antennae Galaxies – Astronomy Picture of the Week
This beautiful image of two colliding galaxies has been released by NASA's great observatories. The Antennae galaxies are located about 62 million light-years from Earth. They take their name from the long antenna-like "arms," which were produced by tidal forces generated in the collision.
15 Things You Didn’t Know About Outer Space [Infographic]
Since the dawn of history, outer space has always caught the imagination of people across the continents and different cultures. However most of what we currently know about space has been discovered since the beginning of the space age over half a century ago.
Dark Matter Map in Galaxy Cluster Abell 1689 – Astronomy Picture of the Week
This image represents the inner region of galaxy cluster Abell 1689 and the distribution of dark matter around it. Abell 1689 is an immense cluster of galaxies located 2.2 billion light-years away. Dark matter cannot be photographed, but its presence can be inferred by observing the light from background galaxies…
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 and super-clusters of galaxies as well as giant voids. It is the largest and most precise model of the Universe ever conceived. The simulation was run in 2005 by the Virgo Consortium, an international group of astrophysicists from Germany, the United Kingdom, Canada, Japan and the United States. One thing that really strikes you as you watch this video is how those galactic clusters are arranged in a pattern that looks like the neurons in our brains. It’s interesting that the Universe takes this form in…
Astronomy Picture of the Week – Galaxy Cluster MS0735
This image of galaxy cluster MS 0735 is actually a composite of three separate images in different wavelengths. The cluster's full scientific designation is MS0735.6+7421. It is located about 2.6 billion light-years away in the constellation of Camelopardalis.
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.
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.
