Majestic on a truly cosmic scale, M100 is appropriately known as a grand design spiral galaxy. It is a large galaxy of over 100 billion stars with well-defined spiral arms that is similar to our own Milky Way Galaxy. One of the brightest members of the Virgo Cluster of galaxies, M100 (alias NGC 4321) is 56 million light-years distant toward the constellation of Berenice's Hair (Coma Berenices). This Hubble Space Telescope image of M100 was made in 2009 and reveals bright blue star clusters and intricate winding dust lanes which are hallmarks of this class of galaxies. Studies of variable stars in M100 have played an important role in determining the size and age of the Universe. If you know exactly where to look, you can find a small spot that is a light echo from a bright supernova that was recorded a few years before the image was taken.

NASA's Hubble Space Telescope has captured an exoplanet's true color. HD 189733b has an azure color that's similar to Earth's, but there is no chance the planet holds life as it orbits extremely close to its host star.

1925 - what were you doing on h'alloween 1925- i had tickets to a houdini show at the moulin rouge but missed it because i was on the titanic hanging out with the cast of downton abbey. #history

2020 - this is the biggest gap between halloween full moons (almost 46 years)

2039 - if you plan on trick-or-treating on this day in 25 years, watch out for werewolves and/or weremice (bats) because the full moon activates their powers

2058 - the full moon on 10/31/2058 will mark the start of armageddon which will conclude on november 5th of the same year

Dusty emission in the Tadpole nebula, IC 410, lies about 12,000 light-years away in the northern constellation Auriga. The cloud of glowing gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893. Formed in the interstellar cloud a mere 4 million years ago, bright cluster stars are seen all around the star-forming nebula.
