Peering ever further back in space and time, the Hubble Space Telescope has glimpsed the largest known group of the faintest and youngest primordial galaxies ever—over 250—some of which are estimated […]

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

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 the […]

Spitzer Space Telescope Discovers Distant Exoplanet Across the Milky Way

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 represents […]

Hubble and Chandra Unveil Mysteries Concerning Dark Matter

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, […]

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

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 fraction […]

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

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 […]

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

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's an Alien Blue World—But Nothing Like Earth

The planets and moons in our Solar System come in a wide variety of colors, and the natural beauty can be breathtaking. Now, the true color of a much more distant […]

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

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.

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 […]
