LENSED QUASAR

LENSED QUASAR Satellite: Hubble Space Telescope Depicts: RXJ1131-1231 Copyright: ESA/Hubble, NASA, Suyu et al. RXJ1131-1231 is among the five best-lensed quasars discovered to date. The foreground galaxy smears the image of the background quasar into a bright arc (left) and creates a total of four images – three of which can be seen within the arc.                 LENSED QUASAR  | Hubble Space Telescope HE0435-1223 is among the five best-lensed quasars discovered to date. The foreground galaxy creates four almost evenly distributed images of the distant quasar around it.   Awesome Nature |galaxy |spiral galaxies |

Sunny Side Up

Sunny Side Up What may first appear as a sunny side up egg is actually NASA/ESA Hubble Space Telescope’s face-on snapshot of the small spiral galaxy NGC 7742. But NGC 7742 is not a run-of-the-mill spiral galaxy. In fact, this spiral is known to be a Seyfert 2 active galaxy, a type of galaxy that is probably powered by a black hole residing in its core. The core of NGC 7742 is the large yellow ‘yolk’ in the center of the image. The lumpy, thick ring around this core is an area of active star birth. The ring is about

Spiral Galaxy a Key to the universe expansion rate

Spiral Galaxy a Key to the universe expansion rate This view from the NASA/ESA Hubble Space Telescope shows the beautiful spiral galaxy NGC 5584. This galaxy has played a key role in a new study that measures the expansion rate of the Universe to greater accuracy than ever before. NGC 5584 was first spotted as a faint glow in the constellation of Virgo by the great visual observer E. E. Barnard, back in 1881, using just a 12.5-cm telescope. But, by bringing the power of Hubble to bear, the galaxy can be resolved into thousands of separate stars. Some of

Saturn in Infrared from Cassini | NASA

Saturn in Infrared from Cassini Image Credit: NASA, JPL-Caltech, SSI.   Explanation: Many details of Saturn appear clearly in infrared light. Bands of clouds show great structure, including long stretching storms. Also quite striking in infrared is the unusual hexagonal cloud pattern surrounding Saturn’s the North Pole. Each side of the dark hexagon spans roughly the width of our Earth. The hexagon’s existence was not predicted, and its origin and likely stability remain a topic of research. Saturn’s famous rings circle the planet and cast shadows below the equator. The featured image was taken by the robotic Cassini spacecraft in 2014

dusty spiral galaxy amazing Picture | Hubble Heritage Team

dusty spiral galaxy amazing Picture In 1995, the majestic spiral galaxy NGC 4414 was galaxy pictures, by the Hubble Space Telescope as part of the HST Key Project on the Extragalactic Distance Scale. An international team of astronomers, led by Dr. Wendy Freedman of the Observatories of the Carnegie Institution of Washington, observed this galaxy on 13 different occasions over the course of two months. galaxy pictures were obtained with Hubble’s Wide Field Planetary Camera 2 (WFPC2) through three different color filters. Based on their discovery and careful brightness measurements of variable stars in NGC 4414, the Key Project astronomers were

Galaxies Merging Creates Tails of Star Birth

Not surprisingly, interacting galaxies have a dramatic effect on each other. Studies have revealed that as galaxies approach one another massive amounts of gas are pulled from each galaxy towards the center of the other until ultimately, the two merge into one massive galaxy. NGC 2623 is in the late stages of the merging process, with the centers of the original galaxy pair now merged into one nucleus, but stretching out from the center are two tidal tails of young stars, a strong indicator that a merger has taken place. During such a collision, the dramatic exchange of mass and
