Yummy! ISS Astronauts Eat First Space-Grown Food

Going where no astronauts have gone before, a trio of "space farmers" living aboard the International Space Station (ISS) have just become the first humans ever to eat food grown in space!

The gleeful munchers downed the freshly harvested crop of blood red colored “Outredgeous” red romaine lettuce salad during a live webcast today, Monday, August 10, direct from the (...)

See Venus at Her Most Ravishing

Venus is HUGE right now but oh-so-skinny as it approaches inferior conjunction on August 15. Like crescents? You’ll never see a thinner and more elegant one, but first you’ll have to find it. Here’s how.

Mysterious Bright Spots and Pyramidal Mountain Star in Dawn's Daunting Flyover of Ceres: Video

 

Video caption: Take a tour of weird Ceres! Visit a 2-mile-deep crater and a 4-mile-tall mountain in the video narrated by mission director Marc Rayman. Get your red/blue glasses ready for the finale – a global view of the dwarf planet in 3D. Credits: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA/LPI/PSI

Mysterious bright spots and a pyramidal shaped mountain star in a daunting new flyover video of dwarf planet Ceres created from imagery gathered by NASA's history making Dawn mission – the first ever to visit any dwarf planet which simultaneously ranks as the largest world in the main asteroid belt residing between Mars and Jupiter.

Ceres was nothing more than a fuzzy blob to humankinds most powerful telescopes like the Hubble Space Telescope (HST), until the probe swooped in this year and(...)

Every year in mid-August, Earth plows headlong into the debris left behind by Comet 109P/Swift-Tuttle. Slamming into our atmosphere at 130,000 mph, the crumbles flash to light as the Perseid meteor shower. One of the world’s most beloved cosmic spectacles, this year’s show promises to be a real crowd pleaser.(...)

Turns out, our seemly placid star had a criminal youth of cosmic proportions.

A recent study out from Leiden Observatory and Cornell University may shed light on the curious case of one of the solar system's more exotic objects: 90377 Sedna.(...)

The Moons of Saturn

Saturn is well known for being a gas giant, and for its impressive ring system. But it would it surprise you to know that this planet also has the second-most moons in the Solar System, second only to Jupiter? Yes, Saturn has at least 150 moons and moonlets in total, though only 53 of these moons have been given official names.

Most of these moons are small, icy bodies that are little more than parts of its impressive ring system. In fact, 34 of those moons that have been named are less than 10 km in diameter, and another 14 are between 10 and 50 km in diameter. However, some of its inner and outer moons are among the largest and most dramatic in the Solar System, ranging from 250 to over 5000 km.

Moon Transits Earth in Eye-poppingly EPIC View from 1 Million Miles Away

See YouTube version and EPIC camera below

An eye-poppingly 'EPIC' view of the sunlit far side of the Moon transiting the sunlit side of Earth was recently captured by NASA's Earth Polychromatic Imaging Camera (EPIC) camera from one million miles away. "Wow!" – is an understatement!

The stunning animation of the Moon crossing in front of the Earth, shown above, and seemingly unlike anything else, was created from a series of images taken in July by NASA's EPIC camera flying aboard the orbiting Deep Space Climate Observatory (DSCOVR), a space weather monitoring satellite, according to a NASA statement.(...)
