WISE Shows us Infrared Views of Time and Space

The Sculptor Galaxy heats up

 

 

WISE uses four infrared detectors to view the Sculptor Galaxy

Wise takes us to the Sculptor Galaxy NGC 253 

Astronomy News – In the next leg of the human “Journey to the Beginning of Space and Time” we travel 11.4 million light years, give or take a few hundred thousand, to the Sculptor Galaxy NGC 253 (the Silver Coin Galaxy) to view an infrared mosaic of images taken by NASA’s Wide-field Infrared Survey Explorer (WISE). Part of the Sculptor group of galaxies (South Polar Group), the 7.6 magnitude Silver Coin Galaxy has infant stars in duty cocoons heating up the galaxies core and broadcasting infrared light into the universe and is the brightest member of the Sculptor group of galaxies. Young emerging stars in the infrared images shown here are concentrated in the galaxies core and along the spiral arms. The green areas are tiny dust or soot particles left after the formation of these emerging stars that have absorbed the ultraviolet light from these young stars, which makes these particles glow with infrared light the four infrared detectors on WISE can detect. The blue image on the top was taken in the short wavelengths, about 3.4 and 4.6 microns, this photo has stars of all ages scattered all over the Sculptor Galaxy. 
 
NGC 253 is considered a starburst galaxy, and an intermediary type of spiral galaxy, with stars forming and exploding at unusually high rates in an intense star-forming period. First recorded by Caroline Herschel, the sister of astronomer William Herschel, on September 23, 1783, the Sculptor Galaxy can best be seen in the Sculptor constellation in the southern night sky in late September by stargazers using a time-machine-to-the-stars. Stargazers with good eyes and a dark sky can even view NGC 253 during this time, just be prepared to spend a little time in the search for the Silver Coin Galaxy.

Astronomy News – The Milky Way use to be thought of as a spiral galaxy, but recently collected data seems to suggest to astronomers that the Milky Way could, in fact, be a barred galaxy. Either way, the human “Journey to the Beginning of Space and Time” has revealed to astronomers a seeming infinity of galaxies beyond the celestial horizon we view from Earth. Spiral galaxies abound in amazing numbers in the universe, elliptical and barred galaxies have been viewed in endless numbers beyond the celestial horizon, and none of these galaxies look exactly the same. Beyond the horizon we view from Earth, the universe astronomers view goes on and on, without an end in sight, but everything we humans have experienced has an ending and beginning. Can the universe truly go on forever, or is it conceivable that somewhere beyond the celestial horizon there exists boundaries beyond which the known universe ends and another reality exists?

Astronomers using the Hubble Space Telescope recently journeyed to spiral galaxy NGC 3982 to look for clues to these questions and others that have fascinated humans since the time of the first-star gazers. A face-on spiral galaxy first discovered by William Herschel on April 14, 1789, NGC 3982’s spiraling arms are lined with pink star-forming regions of space and time glowing with hydrogen, newborn blue star clusters, and star dust capable of providing the raw material for future generations of stars. Astronomers believe hidden in the nucleus of NGC 3982 is a generation of older stars, which become more densely packed as the distance to the center of the nucleus of NGC 3982 lessens. NGC 3982 is an amazing 68 million light-years distant in the constellation Ursa Major and is currently speeding away from the center of the Milky Way Galaxy at a recession velocity of 1187 km/s. NGC 3982 is also a smaller spiral galaxy and spans about 30,000 light years, which is only about one-third the size of our own Milky Way Galaxy.

Astronomers use the Hubble Space Telescope

Astronomers are looking at spiral galaxy NGC 3982, and other similar galaxies, in the hopes of viewing a celestial event of amazing intensity and power, a supernova. They’re currently using the instruments on the Hubble Space Telescope to look for a supernova in the spiral and other galaxies, but soon the James Webb Space Telescope will add its star gazing ability to this job. They want to check current theories on how supernova occur and possibly the types of stars that end their lives in these spectacular explosions. Their search will be primarily in the bright blue knots in NGC 3982’s spiral arms, but they’ll certainly expand their search as the human “Journey to the Beginning of Space and Time” continues to expand.

The Messier Catalogue

Astronomy News – Astronomers looking upward into the night sky realised centuries ago that deep-sky objects are distributed unevenly about the night sky. French comet hunter Charles Messier (1730-1817) looking upward into the night sky through his time-machine-to-the-stars compiled a popular catalog of deep-sky objects. His catalogue contains high concentrations of deep-sky objects within the Milky Way above you, where open star clusters and star-forming areas that form them congregate.

Messier’s catalogue also contains entries on 16 objects he located near the border between the constellations Virgo and Coma Berenices. Star gazer William Herschel (1738-1822) and his son, John Herschel (1792-1871), recorded more than 200 celestial objects in this same region of the night sky. It would be in the 1920s and 1930s that astronomers would determine that these nebulous objects are in fact galaxies as big, or larger than, the Milky Way galaxy that constitute a cluster of galaxies far beyond the Milky Way.

Our Local Group of galaxies

Two decades later, French-born astronomer Gerard de Vaucouleurs (1918-1995) noted that the halo of galaxies surrounding what astronomers referred too as the Virgo cluster actually extends all the way to our Local Group of galaxies, which the Milky Way calls home. Today astronomers refer to this Local Group of galaxies as our Local Supercluster of galaxies.

Presently, astronomers believe our Local Supercluster extends 50 million light-years, from the center of the Virgo cluster. We’ll journey from the center of our Local Group to slightly beyond the Virgo cluster. Along the way we’ll stop at all of the galaxy groups and clusters containing at least three reasonably large galaxies and see what astronomers have determined about these distant celestial bodies in the night sky above you.

The first celestial object in the night sky we’ll journey to see is called the Ursa Major North Group, next we’ll travel to Ursa Major South Group, and then make our way to each of the galaxy groups and clusters in the Milky Way’s Local Group of neighbors.
