Watch Queue Queue It’s so cold that most of the carbon monoxide and nitrogen gases have frozen onto the cloud’s dust grains. The extreme cold is vital to the black cloud’s starry future. News.

These dark clouds may also be the precursors of an isolated and sparsely populated association of low-mass Sun-like stars.Doppler shifts show the cloud’s central parts to be moving inward while its outer layers are moving outward. North is up and East is left. Barnard 68 is classified as a Bok globule, a dark cloud of dense cosmic dust and gas that could collapse and form a dense and hot, low-mass star. Jan 30, 2018 - Image Credit: ESO Barnard 68 (named after the American astronomer Edward Emerson Barnard) is a molecular cloud, dark absorption nebula or Bok globule of about half a … It isn’t sucking in matter that comes too close to it. The difference is that, in the previous image, the blue, green, and red channels showed light in the visible (or very nearly visible) part of the spectrum.

If so, it’s the first Bok globule found to quiver. Figure 20.14 Barnard 68 in Infrared.

Contrary to what your first instinct might tell you upon viewing this image, this is not a black hole. Why this object is interesting: This object will require dark skies (no moon), and will benefit from large aperture.

Barnard 68 (named after the American astronomer Edward Emerson Barnard) is a molecular cloud, dark absorption nebula or Bok globule of about half a light-year across and a mass about twice that of the Sun, located within our Milky Way galaxy, only 400 – 500 light-years away in the southern constellation of Ophiuchus (the Serpent-bearer).

When it contracts, the interior temperature rises. Barnard 68 (named after the American astronomer Edward Emerson Barnard) is a molecular cloud, dark absorption nebula or Bok globule of about half a light-year across and a mass about twice that of the Sun, located within our Milky Way galaxy, only 400 – 500 light-years away in the southern constellation of Ophiuchus (the Serpent-bearer). One of the most famous of these absorbent nebula is a cloud that is paraded to the Ophiuchus constellation known as Barnard 68, seen in the picture.

Using the ESA’s Herschel Space Telescope and evaluation techniques more commonly encountered in Hollywood film productions, the researchers produced a three-dimensional map of the dark cloud Barnard 68, a [continue reading]


Not in the conventional sense anyway. The temperature inside is a mere Astronomers are less than certain about the cloud’s birth and its ultimate fate, but it’s quite likely that the cloud will eventually collapse sometime within the next 100,000 years, giving life to a new, sun-like star.
