Analyzing deep-infrared images obtained by the Spitzer Space Telescope and Gemini North telescope, astronomers discovered that one of the stars in the cluster, HD 23514, which has a mass and luminosity a bit greater than that of the Sun, is surrounded by an extraordinary number of hot dust particles. This could be evidence for planet formation ...
Star map with the Pleiades (upper right) and the Hyades (centre, V-shaped head of the constellation Taurus with its main star Aldebaran, γ Tauri und ε Tauri (Ain)) at both sides of the ecliptic line (dashed red). The Golden Gate of the Ecliptic is an asterism in the constellation Taurus that has been known for several thousand years.
V838 Monocerotis (Nova Monocerotis 2002) is a cataclysmic binary star in the constellation Monoceros about 19,000 light years (6 kpc) from the Sun.The previously unremarked star was observed in early 2002 experiencing a major outburst, and was one of the largest known stars for a short period following the outburst.

Their year began when priests first remarked the asterism heliacal rising in the east, immediately before the Sun's dawn light obliterated the view of the stars. Aztecs called the Pleiades Tiānquiztli (Nahuatl pronunciation: [tiaːŋˈkistɬi]; Classical Nahuatl for "marketplace". Compare tianguis). [41]
NGC 2261 was imaged as Palomar Observatory's Hale Telescope's first light by Edwin Hubble on January 26, 1949, [4] some 20 years after the Palomar Observatory project began in 1928. Hubble had studied the nebula previously at Yerkes and Mt. Wilson. [4] Hubble had taken photographic plates with the Yerkes 24-inch (60.96 cm) reflecting telescope ...
The pillars shown in the image are 5 light-years tall, which means that the distance from one end to the other is roughly 300,000 times as far away as Earth is from the sun.
Now, new pictures taken by the Earth-orbiting Hubble space telescope show Jupiter's red spot is smaller than it has ever been, measuring just under 10,250 miles (16,100 kilometers) in diameter. It ...
Galileo's sketches of the Moon from Sidereus Nuncius. Sidereus Nuncius contains more than seventy drawings and diagrams of the Moon, certain constellations such as Orion, the Pleiades, and Taurus, and the Medicean Stars of Jupiter. Galileo's text also includes descriptions, explanations, and theories of his observations.
