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 candidates [...]
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 Credit: [...]

It was announced this week at the 222nd meeting of American Astronomical Society that Proxima Centauri, a red dwarf and the closest star to the Sun, is predicted to pass in front of two unnamed background stars, one in [...]
The newly discovered galaxy, named MACS0647-JD, is very young and only a tiny fraction of the size of our Milky Way. The object is observed 420 million years after the big bang. The inset at left shows a close-up of the young dwarf galaxy. This image is a composite taken with Hubble’s WFC 3 [...]
