Dawn on Saturn is greeted across the vastness of interplanetary space by the morning star, Venus, in this image from NASA's Cassini spacecraft.

Every so often, our cameras on Cassini digitally record, either intentionally or incidentally, other celestial bodies besides those found around Saturn. The Cassini Imaging Team is releasing a pair of images that did just that. Venus, a lovely shining beacon of light and Earth's `twin' planet, was recently sighted amidst the glories of Saturn and its rings.
Along with Mercury, Earth, and Mars, Venus is one of the rocky "terrestrial" planets in the solar system that orbit relatively close to the sun. It has an atmosphere of carbon dioxide that reaches nearly 900 degrees Fahrenheit (500 degrees Celsius), a surface pressure 100 times that of Earth's, and is covered in thick, white sulfuric acid clouds, making it very bright. Despite a thoroughly hellish environment that would melt lead, Venus is considered a twin of our planet because of their similar sizes, masses, rocky compositions and close orbits.
Think about Venus the next time you find yourself reveling in the thriving flora, balmy breezes, and temperate climate of a lovely day on Earth, and remember: you could be somewhere else!

Since Daguerre’s first images of the moon in 1839, we have sought to capture the essence of the heavens above us through photography. We built observatories equipped with bigger mirrors and better cameras in the hopes that we will be able to see farther and yet more clearly. When those proved to be insufficient, we […]
NASA issued a public $30,000 bounty “for fecal, urine, and menstrual management systems to be used in the crew’s launch and entry suits over a continuous duration of up to 144 hours.” From the competition brief: Current space suits are worn for launch and entry activities and in-space activities to protect the crew from any […]
Cold is easier to deal with than the raging heat of Venus. The Moon and Mars are bathed in dangerous radiation. This means Titan is humanity’s best existential insurance policy. Charles Wohlforth and Amanda Hendrix, authors of Beyond Earth: Our Path to a New Home in the Planets, explain: It’s cold on Titan, at -180°C […]

The ARMOR-X Mini Flexible Phone Tripod is a smartphone tripod that is designed with flexible legs to rest on virtually any type of surface. Other tripods have proved useless unless I conveniently have a flat surface in front of me, which is why this particular tripod was appealing enough to try out. The ARMOR-X is compact and easy […]
You don’t need to get an advanced degree and take out massive loans to become a coder. This bundle of 10 courses was designed to teach anyone to code at home for less than it costs to go out for dinner. I was particularly impressed with this new 2017 bundle because it includes courses on […]
