In the ongoing hunt for the universe’s earliest galaxies, NASA has wrapped up its observations for the Frontier Fields project. This ambitious venture has combined the power of all three of NASA’s orbital observatories — the Spitzer Space Telescope, the Hubble Space Telescope and the Chandra X-ray Observatory — to delve as far back in time and space as current technology can allow.
The TV series “Star Trek” captured the public’s imagination with the signature phrase, “To boldly go where no one has gone before.” The NASA/ESA Hubble Space Telescope doesn’t “boldly go” deep into space, but it is “boldly peering” deeper into the universe than ever before to explore the warping of space and time and uncover some of the farthest objects ever seen.
This incredible image from the NASA/ESA Hubble Space Telescope reveals thousands of colourful galaxies in the constellation of Leo, components of cluster known as MACS J1149.5+2223. This vibrant view of the early universe was captured as part of the Frontier Fields campaign, which aims to investigate galaxy clusters in more detail than ever before.
MACS J0717, some 5.4 billion light-years away from Earth in the constellation of Auriga (The Charioteer), is the result of four galaxy clusters colliding. This image is a combination of observations in visible light, X-rays and radio waves from the NASA/ESA Hubble Space Telescope, NASA’s Chandra X-ray Observatory, and the NRAO Jansky Very Large Array.
Galaxy clusters are enormous collections of hundreds or even thousands of galaxies and vast reservoirs of hot gas embedded in massive clouds of dark matter. To learn more about clusters, including how they grow via collisions, astronomers have used some of the world’s most powerful X-ray, optical and radio telescopes. The name for this galaxy cluster project is the “Frontier Fields”.
Peering deep into the early universe, this picturesque parallel field observation from the NASA/ESA Hubble Space Telescope reveals thousands of colourful galaxies swimming in the inky blackness of space in the constellation Sculptor. This spectacular skyscape was captured during the study of the giant galaxy cluster Abell 2744, otherwise known as Pandora’s Box.
