About Me
"There is a theory which states that is ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable.
There is another theory which states that this has already happened.”

Messier 83
This galaxy is located in the southern constellation Hydra (The Water-Snake) and is also known as NGC 5236; the distance is about 15 million light-years.

Crystal Ball Nebula
NGC 1514 is a planetary nebula that was discovered by William Herschel on November 13th, 1790, describing it “A most singular phaenomenon” and forcing him to rethink his ideas on the construction of the heavens. Up until this point Herschel was convinced that all nebulae consisted of masses of stars too remote to resolve, but now here was a single star “surrounded with a faintly luminous atmosphere.”
He went on to conclude “Our judgement I may venture to say, will be, that the nebulosity about the star is not of a starry nature”. It has since been conjectured that the nebula in fact envelops a tightly orbiting double star with a period of up to 10 days. Gas is presumably expanding away from the larger star of the pair.

Dust Sculptures in the Rosette Nebula
What creates the cosmic dust sculptures in the Rosette Nebula? Noted for the common beauty of its overall shape, parts of the Rosette Nebula, also known as NGC 2237, show beauty even when viewed up close. Visible above are globules of dark dust and gas that are slowly being eroded away by the energetic light and winds by nearby massive stars.

Protostellar
NGC 7538 - The Home of The Largest Known Protostar
A protostar is a large mass that forms by contraction out of the gas of a giant molecular cloud in the interstellar medium. The protostellar phase is an early stage in the process of star formation. —Susan Hewitt

Cygnus X
In The Heart Of Cygnus, NASA’s Fermi Reveals A Cosmic-ray Cocoon
Cygnus X hosts many young stellar groupings, including the OB2 and OB9 associations and the cluster NGC 6910. The combined outflows and ultraviolet radiation from the region’s numerous massive stars have heated and pushed gas away from the clusters, producing cavities of hot, lower-density gas. In this 8-micron infrared image, ridges of denser gas mark the boundaries of the cavities. Bright spots within these ridges show where stars are forming today.

Hubble’s Variable Nebula - NGC 2261
The fan-shaped reflection nebula is made up of dust particles that relfect and scatter mostly blue light from the nearby star R Monocerotis, located in the tip of the nebula at bottom. The shape of the nebula varies over short time periods, believed to be caused by moving opaque clouds of dust and gas between the star and the nebula.

How to See the Stars on the Longest Winter Nights
We are now only a few weeks away from the winter solstice Dec. 22. Anyone who lives in northern latitudes might have noticed how late the sun is rising and how early the sun is setting lately, especially since the end of Daylight Saving Time earlier this month.
Most people think of the winter solstice as the shortest day of the year, but stargazers tend to see it as the longest night of the year. On this date, the sun is above the horizon roughly 9 hours, varying with latitude. Subtracting twilight, the night is fully dark for almost 12 hours.
One result of this long night, combined with the southern position of the sun, is that a very large part of the night sky can be seen in one night. As evening twilight ends, the autumn constellations Cygnus, Pegasus and Aquarius fill the sky.
Then, as morning twilight begins, the spring constellations are visible: Hercules, Boötes, and Virgo. About the only constellations not visible at some point during the night are the ones very close to the sun, such as Ophiuchus, Sagittarius and Scorpius.
