An interstellar cloud is generally an accumulation of gas, plasma, and dust in our and other galaxies. But differently, an interstellar cloud is a denser-than-average region of the interstellar medium , the matter and radiation that exists in the space between the star systems in a galaxy.
The Local Interstellar Cloud (LIC), also known as the Local Fluff, is an interstellar cloud roughly 30 light-years (9.2 pc) across, through which the Solar System is moving. This feature overlaps with a region around the Sun referred to as the solar neighborhood. [2] It is unknown whether the Sun is embedded in the Local Interstellar Cloud, or ...
English: Map showing the Sun located near the edge of our local interstellar cloud (LIC) and alpha centauri about 4 light-years away in the neighboring G-Cloud. V Sun is our Sun's velocity. VLIC is the velocity of the local interstellar cloud.
A nebula that is visible to the human eye from Earth would appear larger, but no brighter, from close by. [6] The Orion Nebula, the brightest nebula in the sky and occupying an area twice the angular diameter of the full Moon, can be viewed with the naked eye but was missed by early astronomers. [7]
The cloud in the top left corner is LBN 1093 and Sh2-1 with the bright star being Pi Scorpii and the yellowish cloud in the middle on the left being Sh2-7 with Dschubba at its center. A starchart of the Galactic Center area, with the Rho Ophiuchi cloud complex marked as large green area in the middle of the right half of the chart.
Solar System dust includes comet dust, planetary dust (like from Mars), [4] asteroidal dust, dust from the Kuiper belt, and interstellar dust passing through the Solar System. Thousands of tons of cosmic dust are estimated to reach Earth's surface every year, [ 5 ] with most grains having a mass between 10 −16 kg (0.1 pg) and 10 −4 kg (0.1 ...
The Sun's location near the edge of the local interstellar cloud and Alpha Centauri about 1.3 pc away in the neighboring G-Cloud. The Sun is located 8,300 pc from the center of the galaxy on the inner edge of the Orion Arm within the diffuse Local Interstellar Cloud (LIC) of the Local Bubble.
The Solar System, and the other stars/dwarfs listed here, are currently moving within (or near) the Local Interstellar Cloud, roughly 30 light-years (9.2 pc) across. The Local Interstellar Cloud is, in turn, contained inside the Local Bubble, a cavity in the interstellar medium about 300 light-years (92.0 pc) across.
