SpaceRanger13, 3 dni temu w M51: The Whirlpool Galaxy angielski M51: The Whirlpool Galaxy Image Credit & Copyright: Michael Sleeman Explanation: The Whirlpool Galaxy is a classic spiral galaxy. At only 30 million light years distant and fully 60 thousand light years across, M51, also known as NGC 5194, is one of the brightest and most picturesque galaxies on the sky. The featured deep image is a digital combination of images taken in different colors over 58 hours with a telescope from Lijiang, China. Anyone with a good pair of binoculars, however, can see this Whirlpool toward the constellation of the Hunting Dogs (Canes Venatici). M51 is a spiral galaxy of type Sc and is the dominant member of a whole group of galaxies. Astronomers speculate that M51’s spiral structure is primarily due to its gravitational interaction with the smaller galaxy just above it.

200ok, 2 dni temu w Plato and the Lunar Alps About one-third the length of the range from the southeast is Mons Blanc, a peak rising to a height of 3.6 km. This compares to a typical height of peaks in this range of 1.8 to 2.4 km. ~ en.wikipedia.org/wiki/Montes_Alpes Those are a lot taller than I imagined! The actual Alps in Europe are just taller than 4km so I can understand the reference.
