Venus

  • Venus: Hothouse Planet
    Before spaceprobes could photograph Venus up close, the second planet from the Sun was often compared to a sister world, much like the Earth. Planetary scientist, David Grinspoon, discusses with Astrobiology Magazine how that view evolved to consider the extremes encountered on the Venusian surface.

  • Venus Transit Casts Earth Shadow
    New satellite data suggest the June blocking of the Sun by Venus reduced our star's available radiance. The same principle makes possible detection of new planets around other stars, as scientists perfect measurements of regular dimming and brightening cycles for our neighbors.

  • Morning Star, Ripped from the Headlines
    The biggest event on the internet for June 2004 was not a sports or political event. The big story was a specialized eclipse that did not even dim the afternoon brightness here on Earth. What was the big deal about Venus?

  • Morning Star Crosses Star
    When Venus eclipsed the Sun, its peculiar atmosphere showed itself briefly. Among rocky bodies like Earth, only Mars, Venus and Saturn's moon, Titan, have much of an atmosphere. But the thick shroud of Venus makes up for others' shortcomings-particularly after a greenhouse took over the

  • Rarest of All Eclipses
    No one alive today could have witnessed the kind of astronomical events to transpire on June 8, when the rarest solar eclipse by Venus will be visible to seventy-five percent of Earth. In 1882-the last time a Venusian transit happened--astronomers recorded first accurate measurements of

  • Venus Above the Clouds
    Venus is a sister planet shrouded by heavy cloud cover. Next week during its milestone transit in front of the Sun, scientists hope to look more carefully at the venusian atmosphere. If this world has water vapor at high altitudes, how did the surface of

  • Planetary Panoramas: The Other Neighbor
    As stunning martian panoramas captivate the world's attention, some interplanetary scientists are also glancing back over time to other surface landers on exotic horizons. Visiting Venus up-close however is not something to do without a camera and flame-retardant gear handy.

  • Planetary Primer: Mars and Venus
    The terrestrial neighborhood is rich with both extremes of hot and cold, depending on whether one looks to Venus or Mars. Whether Venus has too much atmosphere or whether Mars has too little determines whether they rank as hospitable or hostile.

  • Mighty Aphrodite
    Earth's twin, Venus, offers life as we know it few safe places on its faint red-glowing surface, which is hot enough to melt lead. But higher in the clouds, small amounts of water and strange ultraviolet absorbers make for a balmy 107 F abode.

  • Venusian Cloud Colonies
    Thick Venusian clouds mask a dense greenhouse atmosphere that is inhospitably hot. But 30 miles up from the surface, conditions suggest a more temperate zone. Some scientists wonder what strange equilibrium sustains a reactive gas mixture that shouldn't co-exist there: exotic biology or not?
