In astronomy, the Great Rift (sometimes called the Dark Rift or less commonly the Dark River) is a dark band caused by interstellar clouds of cosmic dust that significantly obscure ( extinguish) the center and most radial sectors of the Milky Way galaxy from Earth 's perspective. In dark, clear night skies, the rift appears as clear as the ...
The Large Sagittarius Star Cloud is the innermost galactic structure that can be observed in visible wavelengths, and the most distant portion of the Milky Way that can be seen with unaided eyes. Being depleted of the gas and dust from which new stars form, the region contains no young blue stars. Instead, the brightest stars are K-type orange ...
The Serpens–Aquila Rift (also known as the Aquila Rift) is a region of the sky in the constellations Aquila, Serpens Cauda, and eastern Ophiuchus containing dark interstellar clouds. The region forms part of the Great Rift, the nearby dark cloud of cosmic dust that obscures the middle of the galactic plane of the Milky Way, looking inwards ...
Color–color diagram. A color–color diagram is a means of comparing the colors of an astronomical object at different wavelengths. Astronomers typically observe at narrow bands around certain wavelengths, and objects observed will have different brightnesses in each band. The difference in brightness between two bands is referred to as color.
Composite image showing young stars in and around molecular cloud Cepheus B.. This is a list of star-forming regions located in the Milky Way Galaxy and in the Local Group.Star formation occurs in molecular clouds which become unstable to gravitational collapse, and these complexes may contain clusters of young stars and regions of ionized gas called H II regions.
Zodiacal light is a faint glow of diffuse light in the sky scattered by interplanetary dust, particularly a zodiacal cloud, along the ecliptic, and therefore the zodiac. It is mostly only visible in very dark conditions across the night sky along the whole ecliptic as the zodiacal band, [2] backscattered slightly brighter from an oval area of ...
Cosmic dust – also called extraterrestrial dust, space dust, or star dust – is dust that occurs in outer space or has fallen onto Earth. [1] [2] Most cosmic dust particles measure between a few molecules and 0.1 mm (100 μm ), such as micrometeoroids. Larger particles are called meteoroids. Cosmic dust can be further distinguished by its ...
The exoplanet closely orbits its host star, and the intense heat and radiation received from that sun-like star — more than 4,000 times the amount of radiation that Earth gets from our sun ...
