The discovery provides new and exciting information that could better our understanding of some astrophysics, including how certain galaxies obtain their shapes [4]; how intergalactic space becomes enriched with heavy elements [5]; and even from where unexplained cosmic infrared background radiation may arise [6].

Along with the familiar cosmic microwave background — the afterglow of the big bang — the distant universe is suffused with an infrared background, thought to come from galaxies and stars too faint and far away to see.

They found that about 63 percent of the background radio emission comes from galaxies with gorging black holes at their cores and the remaining 37 percent comes from galaxies that are rapidly forming stars.

The telescope has helped researchers detect such clusters by exploiting a phenomenon known as the Sunyaev - Zel «dovich effect, which causes massive galaxy clusters to leave an impression on the cosmic microwave background: a faint, universe - spanning glow of light left over from the big bang.

ALMA picked up on the distorted infra - red light from an unrelated background galaxy, revealing the location of the otherwise invisible dark matter that remained unidentified in their previous study.

The purported swirls in the cosmic microwave background could in fact be a spurious signal from within our galaxy, a rumor suggests.

Thanks to the dry, clear atmosphere at the South Pole, SPT is better able to «look» at the cosmic microwave background — the thermal radiation left over from the Big Bang — and map out the location of galaxy clusters, which are hundreds to thousands of galaxies that are bound together gravitationally and among the largest objects in the universe.

One cool detail: Our home galaxy, the Milky Way, and our sister galaxy, Andromeda, move at 1.4 million miles per hour relative to the ubiquitous background energy left over from the Big Bang, a standard frame of reference for astronomers.

In the background are the blue and red elongated shapes of many other galaxies, which lie at vast distances from us — but which can all be seen by the sharp eye of Hubble.

The small white boxes, labeled «a,» «b,» and «c,» mark multiple images from the same background galaxy, one of the farthest, faintest, and smallest galaxies ever seen.

According to standard physics, cosmic rays created outside our galaxy with energies greater than about 1020 electronvolts (eV) should not reach Earth at those energies: as they travel over such vast regions of space they should lose energy because of collisions with photons of the cosmic microwave background (CMB), the radiation left over from the big bang.

The cluster is so massive that its powerful gravity bends the light from galaxies far behind it, making background objects appear larger and brighter in a phenomenon called gravitational lensing.

[4] Gravitational lensing magnifies the light from fainter, background objects, allowing Hubble to spy galaxies it would otherwise not be able to detect.

«We had expected we would see faint emissions right on top of the quasar, and instead we saw strong bright carbon emission from the galaxies at large separations from their background quasars,» said J. Xavier Prochaska, professor of astronomy and astrophysics at UC Santa Cruz and coauthor of the paper.

The sharp Hubble and Keck Observatory images allowed the research teams to separate out the background source star from its neighbors in the very crowded star field in the direction of our galaxy's center.
