If you have not visited the Hubble  astro site you have probably  seen one of the incredible pictures interpreted from the mass of data coming from the Hubble telescope. Just in case you have not seen any -take a look at these recent images  based on Hubble data. You may also like to celebrate 20 years of HUBBLE and marvel, that data is  coming from’the edge of the known universe‘ -something to think about!

NGC4911

3 AUGUST 10, 2010: A long-exposure Hubble Space Telescope image shows a majestic face-on spiral galaxy located deep within the Coma Cluster of galaxies, which lies 320 million light-years away in the northern constellation Coma Berenices. The galaxy, known as NGC 4911, contains rich lanes of dust and gas near its center. These are silhouetted against glowing newborn star clusters and iridescent pink clouds of hydrogen, the existence of which indicates ongoing star formation. Hubble has also captured the outer spiral arms of NGC 4911, along with thousands of other galaxies of varying sizes. The high resolution of Hubble’s cameras, paired with considerably long exposures, made it possible to observe these faint details.

This natural-color Hubble image, which combines data obtained in 2006, 2007, and 2009 from the Wide Field Planetary Camera 2 and the Advanced Camera for Surveys, required 28 hours of exposure time.

AUGUST 5, 2010: A beautiful new image of two colliding galaxies has been released by NASA’s Great Observatories. The Antennae galaxies, located about 62 million light-years from Earth, are shown in this composite image from the Chandra X-ray Observatory (blue), the Hubble Space Telescope (gold and brown), and the Spitzer Space Telescope (red). The imaging data were taken in 1999, 2003, 2004, and 2005. The Antennae galaxies take their name from the long antenna-like “arms,” seen in wide-angle views of the system. These features were produced by tidal forces generated in the collision.

star leaves milky way

JULY 22, 2010: A hundred million years ago, a triple-star system was traveling through the bustling center of our Milky Way galaxy when it made a life-changing misstep. The trio wandered too close to the galaxy’s giant black hole, which captured one of the stars and hurled the other two out of the Milky Way. Adding to the stellar game of musical chairs, the two outbound stars merged to form a super-hot, blue star.

This story may seem like science fiction, but astronomers using NASA’s Hubble Space Telescope say it is the most likely scenario for a so-called hypervelocity star, known as HE 0437-5439, one of the fastest ever detected. It is blazing across space at a speed of 1.6 million miles (2.5 million kilometers) an hour, three times faster than our Sun’s orbital velocity in the Milky Way. Hubble observations confirm that the stellar speedster hails from our galaxy’s core.

and now some dark energy..

I think if you want young people to be interested in science or just to marvel at the space beyond our seemingly ‘shrinking world’ then it is certainly worth getting them to explore hubble images and just imagine….
