![]() ![]() This hot gas was created when ejected material from the supernova smashed into surrounding gas and dust at speeds of about ten million miles per hour.Ī comparison of the infrared and X-ray images of Cas A should enable astronomers to better understand how relatively cool dust grains can coexist in the superhot gas that produces the X-rays. Chandra shows hot gases at about 10 million degrees Celsius. Spitzer reveals warm dust in the outer shell with temperatures of about 26 degrees Celsius (80 degrees Fahrenheit), and Hubble sees the delicate filamentary structures of warmer gases about 10,000 degrees Celsius. Each Great Observatory image highlights different characteristics of the remnant. Infrared data from the Spitzer Space Telescope are colored red optical data from the Hubble Space Telescope are yellow and X-ray data from the Chandra X-ray Observatory are green and blue.Ĭas A is the 300-year-old remnant created by the supernova explosion of a massive star. This stunning picture of the supernova remnant Cassiopeia A (Cas A) is a composite of images taken by three of NASA's Great Observatories. ![]() On Twitter, Facebook, Google News, and Instagram.Credit: X-ray: NASA/CXC/SAO Optical: NASA/STScI Infrared: NGC 1566's flaring center makes the spiral one of the closest and brightest Seyfert galaxies, likely housing a central supermassive black hole wreaking havoc on surrounding stars and gas.įollow HT Tech for the latest tech news and reviews, also keep up with us Some of these images, stored online in the Hubble Legacy Archive, were freely downloaded, combined, and digitally processed by an industrious amateur to create the featured image. Numerous Hubble Space Telescope images of NGC 1566 have been taken to study star formation, supernovas, and the spiral's unusually active center. Classified as a grand design spiral, NGC 1566 shows two prominent and graceful spiral arms that are traced by bright blue star clusters and dark cosmic dust lanes. An island universe containing billions of stars and situated about 40 million light-years away toward the constellation of the Dolphinfish (Dorado), NGC 1566 presents a gorgeous face-on view. If not perfect, then this spiral galaxy is at least one of the most photogenic. It has certainly proved fruitful as most of Hubble's images have been captured by the ACS. The Advanced Camera for Surveys (ACS) was primarily designed to survey large areas of the sky at visible and red wavelengths with 10 times greater efficiency than the earlier premier Hubble camera. To capture such objects, Hubble has advanced optical instruments such as the Advanced Camera for Surveys and Wide Field Camera 3. Despite being nearly 3 decades old, it still amazes us with stunning images of far-off celestial objects. This stunning discovery by the Hubble Telescope further proves the capabilities of the Hubble Space Telescope. According to NASA, several images of this galaxy have been captured to study star formation, supernovas, and the spiral's unusually active center. Within the galaxy are blue star clusters and dark cosmic dust lanes which follow two prominent spiral arms. Today's NASA Astronomy Picture of the Day is a snapshot of NGC 1566, also known as the Spanish Dancer Spiral Galaxy, located about 40 million light-years away towards the constellation of Dorado. Moreover, some of these galaxies have unusual shapes like a hamburger, toothpicks, rings and more. These galaxies exhibit an array of sizes, ranging from diminutive dwarf galaxies with a meager population of a few billion stars to colossal elliptical galaxies with trillions of stars. Some of these include Centaurus A Galaxy, Hamburger Galaxy, Rubin's Galaxy, Arp 78 and more. NASA, with the help of its various advanced telescopes such as Spitzer Space Telescope, the Hubble Space Telescope, and the newly launched James Webb Space Telescope, has published fascinating images of galaxies thousands and even millions of light-years away. ![]()
