A star-forming region in the Large Magellanic Cloud. A star is a luminous spheroid of plasma held together by self-gravity. [ 1] The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night; their immense distances from Earth make them appear as fixed points of light.
Star formation is the process by which dense regions within molecular clouds in interstellar space, sometimes referred to as "stellar nurseries" or " star -forming regions", collapse and form stars. [ 1] As a branch of astronomy, star formation includes the study of the interstellar medium (ISM) and giant molecular clouds (GMC) as precursors to ...
This is a list of flags, arranged by design, serving as a navigational aid for identifying a given flag.Uncharged flags are flags that either are solid or contain only rectangles, squares and crosses but no crescents, circles, stars, triangles, maps, flags, coats of arms or other objects or symbols.

The night sky is the nighttime appearance of celestial objects like stars, planets, and the Moon, which are visible in a clear sky between sunset and sunrise, when the Sun is below the horizon . Natural light sources in a night sky include moonlight, starlight, and airglow, depending on location and timing. Aurorae light up the skies above the ...
A "blue moon" refers to a second full moon that falls within the same month span. "A blue moon is really a rare phenomenon," explains Lisa Stardust, astrologer and author. "A blue moon occurs ...
Astronomical object. An astronomical object, celestial object, stellar object or heavenly body is a naturally occurring physical entity, association, or structure that exists within the observable universe. [ 1] In astronomy, the terms object and body are often used interchangeably. However, an astronomical body or celestial body is a single ...
Stellar classification. In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines.
