Venus is a landscape of valleys and high mountains dotted with thousands of volcanoes. Its surface features – most named for both real and mythical women – include Ishtar Terra, a rocky, highland area around the size of Australia near the north pole, and an even larger, South-America-sized region called Aphrodite Terra that stretches across ...

2024年5月16日 · Venus is the second planet from the Sun, and the sixth largest planet. It’s the hottest planet in our solar system.

NASA’s real-time science encyclopedia of deep space exploration. Our scientists and far-ranging robots explore the wild frontiers of our solar system.

Venus was the first planet explored by a spacecraft and was intensely studied early in the history of space exploration. Venus was also the first planet whose surface was reached by a spacecraft from Earth. The intense heat means landers have only survived for a couple of hours.

It is unlike the terrestrial planets (Mercury, Venus, Earth, Mars), or the gas giants (Jupiter, Saturn), or the ice giants (Uranus, Neptune). Charon, its huge satellite, is nearly half the size of Pluto and shares Pluto's orbit.

Over the course of one Venus rotation (243 Earth days), the Magellan spacecraft will map most of the surface with detail that exceeds that of the best previous radar images. The resultant maps will reveal the traces (if they exist) of many fundamental planetary forces: volcanism, wind, water, and meteorite impacts -- in short, all the processes ...

2019年3月12日 · Twenty-five years ago, scientists discovered that Earth orbits the Sun within a giant ring of dust. Others uncovered a similar ring near Venus’ orbit, first using archival data from the German-American Helios space probes in 2007, and …

These three perspective images show the structure of Venus at the surface, in the crust and in the mantle. The upper plane shows surface features seen by Magellan's imaging radar "draped" over a three-dimensional representation of surface topography seen by the altimeter.

An imaginary tour around the planet evokes memories of some of the most notable women of history and mythology. Continent-sized highland areas (terrae) are named for counterparts of Venus, the Roman goddess of love (see Figure 8-1). The northern highland, Ishtar Terra, honors the Babylonian goddess of love (and war).

2025年1月9日 · After successfully delivering its payload at Venus, Vega 1 flew on to a close encounter with comet Halley, transmitting hundreds of image as it through through the comet's gas cloud, or coma. Vega 1 collected valuable data on Halley's nucleus, dust production rate, chemical composition and rotational rate.
