To the Edge of Time: Celebrating 25 Years of Hubble Science (Part 4)

By Leonidas Papadopoulos, on May 2nd, 2015

The breathtaking image of the Hubble eXtreme Deep Field, which was created from data that had been collected with the Hubble Space Telescope in 2003 and 2004. In order for the image to be created, the space telescope pointed towards a small patch of the sky for a total of 50 days, while […]

Spitzer Space Telescope Discovers Distant Exoplanet Across the Milky Way

By Leonidas Papadopoulos, on April 16th, 2015

Utilising NASA’s Spitzer Space Telescope, astronomers have discovered a distant exoplanet located 13,000 light-years away, through gravitational microlensing. The red cone in the map above our Solar System, depicts the extend in the galaxy of the thousands of known exoplanets that have been discovered by NASA’s Kepler space telescope, while the red circle […]

Hubble and Chandra Unveil Mysteries Concerning Dark Matter

By Emily Carney, on April 1st, 2015

From HubbleSite: “This collage shows images of six different galaxy clusters taken with NASA’s Hubble Space Telescope and Chandra X-ray Observatory. The clusters were observed in a study of how dark matter in clusters of galaxies behaves when the clusters collide. Seventy-two large cluster collisions were studied in total. Using visible-light images from […]

Hubble Observes the 'Ghost Light' of Orphaned Stars Inside Galaxy Cluster

By Leonidas Papadopoulos, on November 1st, 2014

The massive galaxy cluster Abell 2744 takes on a ghostly look in this view by the Hubble Space Telescope, where the total starlight from the cluster has been artificially colored blue. This reveals that not all the starlight is contained within the galaxies, which appear as bright blue-white blobs in the image. A […]

Looking Beyond: NASA's Frontier Fields Possibly Finds One of the Youngest Galaxies in the Early Universe

By Leonidas Papadopoulos, on February 25th, 2014

This image of the galaxy cluster Abell 2744 was obtained with NASA’s Hubble Space Telescope, as part of the Frontier Fields program, designed to push the limits of how far we can see into the early universe. The zoomed image shows the region around the galaxy Abell2744_Y1, one of the most distant galaxy […]

Probing the Dawn of Time: Hubble Frontier Fields Releases First Views of Distant, Previously Unseen Galaxies

By Leonidas Papadopoulos, on January 9th, 2014

A long-exposure image of galaxy cluster Abell 2744, obtained by the Hubble Space Telescope, as part of the Hubble Frontier Fields program. The long blue streaks surrounding the cluster in the image come from the light of much more distant galaxies, located as far as 13 billion light-years away behind the cluster. Image […]

Hubble Space Telescope Reveals Evidence of Farthest Known Planet From Its Star

By Emily Carney, on June 14th, 2013

A gap in the protoplanetary disk of dust and gas whirling around TV Hydrae uncovered evidence of an unseen, growing planet, according to astronomers studying Hubble data. Image Credit: NASA, ESA, J. Debes (STScI), H. Jang-Condell (University of Wyoming), A. Weinberger (Carnegie Institution of Washington), A. Roberge (Goddard Space Flight Center), G. Schneider […]
