To represent Aphrodite and Cupid fleeing the approach of the sea monster Typhon (nearby Cetus). Alrescha is a good double star through a moderate telescope, while Zeta Piscium is another double that can be resolved into its components through even the smallest instrument. The “First Point of Aries,” marking the northern vernal equinox where the ecliptic crosses from the southern to the northern hemisphere of the sky (see here) lies near the constellation’s southern edge. It marks the origin.
Brilliant Orion, the large “W” of Monoceros provides a much fainter observing prospect. Fortunately, Procyon, the brightest star of Canis Minor, lies directly to its north. Monoceros is Greek for unicorn, the legendary beast with a single horn on its head. Monoceros stretches across a bright region of the Milky Way, which makes its pattern all the more difficult to distinguish. It is widely thought to have been invented by Dutch theologian Petrus Plancius around 1613, although some early.
6530, overlays the nebula’s eastern half and is thought to have emerged in the last 2 million years. R.A. 18h 04m, DEC. -24º23’ MAGNITUDE 6.0 DISTANCE 5,000 light years Sagittarius The Galactic Center High Contrast This beautiful long-exposure view of the region around Sagittarius and Scorpius captures the blaze of light from countless stars in the Milky Way, contrasting with the spine of dust that runs along the Sagittarius/Carina spiral arm. The bright knots of the Lagoon and Trifid.
Small patch of apparently empty sky in Ursa Major. Combining the multiple exposures using computerized image processing, NASA scientists produced the Hubble Deep Field (HDF)—a view that reveals some 3,000 galaxies stretching across billions of light years of space and offers a new perspective on the Universe. R.A. 12h 37m, DEC. +62º12’ MAGNITUDE < 28 DISTANCE Up to 12 billion light years Bode’s Galaxy Messier 81 This tightly wound spiral galaxy, 12 million light years from Earth, bears the.
Around 600 million years ago. The repercussions of this event are still being felt as disrupted material continues to fall onto the galaxy’s central supermassive black hole, fueling its ongoing activity.
