Rho Ophiuchi is the small group of stars in the blue nebulosity (IC 4604). The central pair is known as Rho Ophiuchi AB. It consists of at least two blue-colored subgiants or main-sequence stars, designated Rho Ophiuchi A and B, respectively. [11]

The Rho Ophiuchi cloud complex is a complex of interstellar clouds with different nebulae, particularly a dark nebula which is centered 1° south of the star ρ Ophiuchi, which it among others extends to, of the constellation Ophiuchus.

2020年9月13日 · Rho Ophiuchi (ρ Oph) is a multiple star system located at an approximate distance of 360 light years from Earth in the constellation Ophiuchus. The main pair in the system, Rho Ophiuchi AB, has a combined apparent magnitude of 4.63 and, while it is visible to the unaided eye, it is not among the 20 brightest points of light in Ophiuchus.

2023年7月28日 · The Rho Ophiuchi cloud complex is a large complex of bright and dark nebulae located 460 light-years away in the constellation Ophiuchus. It surrounds the star system Rho Ophiuchi and is one of the nearest star-forming regions to the Sun.

2023年3月16日 · The Rho Ophiuchi region lies along the edge of the Milky Way galaxy as seen from Earth. The Northern Hemisphere gets its best view of Ophiuchus, Scorpius and this general region of the Milky Way...

2023年7月12日 · The first anniversary image from the NASA/ESA/CSA James Webb Space Telescope displays star birth like it’s never been seen before, full of detailed, impressionistic texture. The subject is the Rho Ophiuchi cloud complex, the closest star-forming region to Earth.

2008年3月23日 · Newborn stars peek out from beneath their natal blanket of dust in this dynamic image of the Rho Ophiuchi dark cloud from NASA's Spitzer Space Telescope. Called "Rho Oph" by astronomers, it's one of the closest star-forming regions to our own solar system. Located near constellations Scorpius and Ophiuchus, the nebula is about 407 light years away.

2017年7月9日 · The Rho Ophiuchi nebular complex is a beautiful, gigantic cloud of colorful cosmic dust and gas located 460 light-years from Earth in the constellation Ophiuchus. It's one of the closest stellar...

Though a pretty sight through a small telescope, and an interesting hot double in its own right, Rho is far more famed for its setting within dusty clouds of the Milky Way, the luminous band that is caused by the combined light of the stars in the disk of our Galaxy. Surrounding Rho is a bright "reflection nebula" caused by starlight that is ...
