•Galactic Broken Star•

[tethrasing-deactivated20170803]

to believe in a universe as young as six or seven thousand years old is to extinguish the light from most of the galaxy, not to mention from all the hundred billion other galaxies in the observable universe

In the Heart of the Rosette Nebula by Don Goldman

In the heart of the Rosette Nebula lies a bright open cluster of stars that lights up the nebula.

The stars of NGC 2244 formed from the surrounding gas only a few million years ago.

The above image taken in January using multiple exposures and very specific colors of Sulfur (shaded red), Hydrogen (green), and Oxygen (blue), captures the central region in tremendous detail.

NGC 4631 (also known as the Whale Galaxy or Caldwell 32) is a barred spiral galaxy in the constellation Canes Venatici. This galaxy’s slightly distorted wedge shape gives it the appearance of a herring or a whale, hence its nickname. It contains a central starburst, which is a region of intense star formation. The strong star formation is evident in the emission from ionized hydrogen and interstellar dust heated by the stars formed in the starburst.

Barnard 68 is a molecular cloud, dark absorption nebula or Bok globule, towards the southern constellation Ophiuchusand well within our own galaxy at a distance of about 400 light-years, so close that not a single star can be seen between it and the Sun. Because of its opacity, its interior is extremely cold, its temperature being about 16 K (−257 °C). Its mass is about twice that of the Sun and it measures about half a light-year across.

The Crescent Nebula is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It is formed by the fast stellar wind from the Wolf-Rayet star colliding with and energizing the slower moving wind ejected by the star when it became a red giant. The result of the collision is a shell and two shock waves, one moving outward and one moving inward.

The Solar System is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly.The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud.The vast majority of the system's mass is in the Sun, with the majority of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The two largest, Jupiter and Saturn, are gas giants; the two outermost planets, Uranus and Neptune, are ice giants

The Horsehead Nebula (also known as Barnard 33) is a dark nebula in the constellation Orion. The dark cloud of dust and gas is a region in the Orion Molecular Cloud Complex where star formation is taking place. The red or pinkish glow originates from hydrogen gas predominantly behind the nebula, ionized by the nearby bright star Sigma Orionis.

The Iris Nebula is a bright reflection nebula in the constellation Cepheus, actually the cluster within the nebula. It lies 1,300 light-years away and is six light-years across.

Swirling bands of light and dark clouds on Jupiter are seen in this image made by citizen scientists using data from our Juno spacecraft. Each of the alternating light and dark atmospheric bands in this image is wider than Earth, and each rages around Jupiter at hundreds of miles (km) per hour. The lighter areas are regions where gas is rising, and the darker bands are regions where gas is sinking. This image was acquired on May 19, 2017 from about 20,800 miles (33,400km) above Jupiter’s cloud tops. Learn more

Betelgeuse, also designated Alpha Orionis, is the second-brightest in the constellation of Orion. Is a very large, luminous but cool star classified as a red supergiant, belonging to the M spectral class.

Maybe the time is not quite yet. But those other worlds, promising untold opportunities beckon. Silently, they orbit the Sun, waiting.
