Destiabr Nebula

The Destiabr Nebula is a planetary nebula located on the coreward edge of Chiep Zhez Sector.

• It is an astrographic feature and a nebula.
• It lies within Charted Space.

Description (Specifications)

The Destiabr nebula is the remnant of a supernova event. In the distant past a giant star reached the end of its life and exploded, scattering the material that it was made up of into interstellar space.

• The core of the nebula is a glowing, gradually expanding cloud measuring around 0.25 parsecs (0.8 light years) in diameter and centered on two extremely hot white dwarf stars.
• It is surrounded by a vast cloud of interstellar gas and dust measuring some 3 parsecs coreward-rimward by 4 parsecs spinward-trailing.

The structure is classified as a planetary nebula and is primarily formed of ionized gases, thrown off by the giant stars that used to exist at its center many millennia ago.

• The gases consist of about 90% molecular hydrogen (H₂), with the remainder made up of varying concentrations of helium (He), oxygen (O₂), nitrogen (N₂), and other elements. The clouds have a mean density of 10²–10⁶ particles/cm³.

The nebula is centered on the Destiabr system.

• Two white dwarf stars -- the glowing hot cores of the former giant stars -- and a few orbiting rocks are all that remains of the former star system.
• A miasma of molecular particles sleets through the system. This interferes with communications and sensors.

History & Background (Dossier)

The densest parts of the nebula, with concentrations of particles in excess of a million per cm³, are called molecular cores. The quantities of dust and ionized gases within a core is sufficient to block light from background stars so that it appears as a darker region within the nebula. Each core generally measures a few thousand AU in diameter.

• Occasionally, a particularly dense pocket of material may gain enough static charge to trigger a powerful plasma discharge.
• Radiation levels within the molecular cloud are significantly elevated, rising to as high as 200 Rads per hour.
