PIX4617491: Bok's cells in NGC 281 (Cassiopee) - Bok globules in NGC 281 - View of a detail of the nebula NGC 281 in Cassiopee center on Bok's Globules. A Bok's blood cell is a dark interstellar cloud of gases and dust that absorb light. If it condenses enough, it gives birth to new stars. Near these blood cells shine blue stars; they belong to the young cluster of stars IC 1590. Image obtained by the Hubble Space Telescope in October 2005. These opaque, dark knots of gas and dust are called “” Bok globules,””” and they are absorbing light in the center of the nearby emission nebula and star - forming region. Bok hypothesized that giant molecular clouds, on the order of hundreds of light - years in size, can become perturbed and form small pockets where the dust and gas are highly concentrated. These small pockets become gravitationally bound and accumulate dust and gas from the surrounding area. If they can capture enough mass, they have the potential of creating stars in their cores; however, not all Bok globules will form stars. Some will dissipate before they can collapse to form stars. That may be what's happening to the globules seen here in NGC 281. Near the globules are bright blue stars, members of the young open cluster IC 1590. The cluster is made up of a few hundred stars. The club's core, off the image towards the top, is a tight grouping of extremely hot, massive stars with an immense stellar wind. The stars emit visible and ultraviolet light that energizes the surrounding hydrogen gas in NGC 281. This gas then becomes super heated in a process called ionization, and it glows pink in the image. The Bok globules in NGC 281 are located very close to the center of the IC 1590 cluster. The heavy fracturing of the globules may appear beautifully serene but is in fact evident of the harsh / Bridgeman Images
