APOD: M33: The Triangulum Galaxy (2019 Dec 31)

Post by APOD Robot » Tue Dec 31, 2019 5:05 am

Image M33: The Triangulum Galaxy

Explanation: The small, northern constellation Triangulum harbors this magnificent face-on spiral galaxy, M33. Its popular names include the Pinwheel Galaxy or just the Triangulum Galaxy. M33 is over 50,000 light-years in diameter, third largest in the Local Group of galaxies after the Andromeda Galaxy (M31), and our own Milky Way. About 3 million light-years from the Milky Way, M33 is itself thought to be a satellite of the Andromeda Galaxy and astronomers in these two galaxies would likely have spectacular views of each other's grand spiral star systems. As for the view from planet Earth, this sharp image shows off M33's blue star clusters and pinkish star forming regions along the galaxy's loosely wound spiral arms. In fact, the cavernous NGC 604 is the brightest star forming region, seen here at about the 7 o'clock position from the galaxy center. Like M31, M33's population of well-measured variable stars have helped make this nearby spiral a cosmic yardstick for establishing the distance scale of the Universe.

Lovely, colorful picture. M33 does look like a spinning pinwheel with fireworks going off everywhere.

<<Cotton candy is a spun sugar confection that resembles cotton. It usually contains small amounts of flavoring and/or food coloring. The candy is made by heating and liquefying sugar, spinning it centrifugally through minute holes — and finally allowing the sugar to rapidly cool and re-solidify into fine strands. It is often sold at fairs, circuses, carnivals, and festivals — served on either a stick, paper cone or in a plastic bag.

Several places claim the origin of cotton candy, with some sources tracing it to a form of spun sugar found in Europe in the 19th century. At that time, spun sugar was an expensive, labor-intensive endeavor and was not generally available to the average person. Others suggest versions of spun sugar originated in Italy as early as the 15th century.

Machine-spun cotton candy was invented in 1897 by dentist William Morrison and confectioner John C. Wharton, and first introduced to a wide audience at the 1904 World's Fair as "Fairy Floss" with great success, selling 68,655 boxes at 25¢ (equivalent to $6.97 in 2018) per box. Joseph Lascaux, a dentist from New Orleans, Louisiana, invented a similar cotton candy machine in 1921. In fact, the Lascaux patent named the sweet confection “cotton candy” and the "fairy floss" name faded away, although it retains this name in Australia.>>

¡Cuidado con la foto del día de mañana! La nueva década no se iniciará mañana, sino el 01 de enero de 2021. Igualmente, el primer año de este siglo y de este milenio fue 2001, no 2000. El primer año fue el año 1, no el año cero, el cual ni siquiera existió. :shock:

I wonder how many other teeth rotting schemes where invented by dentists? It's enough to make one an antidentite! :lol2:

Back to astronomy. From the explanation,
In fact, the cavernous NGC 604 is the brightest star forming region, seen here at about the 7 o'clock position from the galaxy center.
The link on "cavernous NGC 604" says that it is nearly 100 times larger than our galaxy's Orion nebula. Wow.

<<NGC 604 is roughly 1,520 light years, over 40 times the size of the visible portion of the Orion Nebula (~24 light years across). It is over 6,300 times more luminous than the Orion Nebula, and if it were at the same distance (1,344 light years) it would outshine Venus. Its gas is ionized by a cluster of massive stars at its center with 200 stars of spectral type O and WR, a mass of 100,000 M [M42 has a mass of 2,000 M], and an age of 3.5 million years; however, unlike the Large Magellanic Cloud's Tarantula Nebula central cluster (R136) [90,000 M, 1.5 million years old], NGC 604's one is much less compact and more similar to a large stellar association.>>
