HTTP:: Hubble Captures Massive Galactic Mash Up
--------
The Hubble Space Telescope has recently imaged a very weird-looking galaxy, which appears to be a two-armed spiral one at first glance. However, upon closer inspection, astronomers discovered that the formation was, in fact, the result of a massive, high-speed collision, taking place approximately 250 million light-years away from the Earth. The experts also noticed blue-colored areas of intense stellar formation in the resulting arms, hinting at huge amounts of stellar dust and gas being generated, and then collapsing onto themselves to form new stars.The resulting galaxy, dubbed NGC 2623, or Arp 243, is located in the constellation Cancer, and it is extremely active in infrared wavelengths. As such, it has been included in the luminous infrared galaxy (LIRG) group, scientists explain. It has been extensively studied as the part of the Great Observatories All-sky LIRG Survey (GOALS), which combines data from a large number of ground- and space-based telescopes, including t!
he Hubble. When dealing with cosmic objects such as active galactic nuclei and nuclear star formation, data from X-ray and infrared observatories are also included.The reason why so many stellar nurseries appear in the two trailing arms is because, as the galaxies approach each other, massive amounts of gas are ...
