On February 23rd, I reluctantly attended the showing of a film called “Is Genesis History?”
IS GENESIS HISTORY? is a comprehensive documentary featuring creationist scientists and scholars looking at the world and explaining how it intersects with the history recorded in Genesis. From rock layers to fossils to lions to stars, this film attempts to challenge and change the way you see the world.

We hope the flat-earthers are paying attention. Humanity has one again passed your imaginary ‘firmament’.
Today, humanity once again left this tiny fragile world. Photo at right shows Soyuz spacecraft on final approach to the International Space Station carrying Jeff Williams, Alexey Ovchinin and Oleg Skripochka. Let us wish them well as they begin their adventure on the ISS.

Eric Hovind 5 Part IV: Abstract Thinking In this video, we analyze Eric's thoughtful equation 'Confusion, Confusion, Confusion, THEREFORE God'
It's about time we explained why Science Denier Hall of Shame exists. Here's the short answer.
Buster the Pug asks: Is Eric Dubay an idiot, or a liar? Decide for yourself. #FlatEarth #EricDubay
Eric Hovind is at it again. Following in his father Kent Hovind’s footsteps, he happily dismisses the theory of evolution, the Big Bang theory, the geologic column and just about everything else modern science has discovered. The alternative he (and Kent) offer? ‘GODDIDIT! In this episode, Eric uses one of his dad’s best tricks;…

This week, we’re setting out on an ambitious quest: our first mission to retrieve a sample from an asteroid and return it to the Earth.
1. Take It from the Beginning
Some asteroids are time capsules from the very beginnings of our solar system. Some meteorites that fall to Earth originate from asteroids. Laboratory tests of materials found in meteorites date to before the sun started shining. OSIRIS-REx’s destination, the near-Earth asteroid Bennu, intrigues scientists in part because it is thought to be composed of the primitive building blocks of the solar system.
Meet asteroid Bennu
Take a tour of asteroids in our solar system.
2. Creating the Right Ship for the Journey
At the heart of the OSIRIS-REx mission is the robotic spacecraft that will fly to Bennu, acting as the surrogate eyes and hands of researchers on Earth. With its solar panels deployed, the craft is about 20 feet (6 meters) long and 10 feet (3 meters) high. Packed into that space are the sample retrieval system, the capsule for returning the sample to the ground on Earth, plus all the hardware for navigation and communicating with home.
Explore the instruments and how they work
3. School of Hard Rocks
If you’re a teacher or a student, the OSIRIS-REx mission and exploring asteroids make for some engaging lesson material. Here are some of the things you can try.
Find dozens of lesson plans
4. Standing (or Flying) on the Shoulders of Giants
OSIRIS-REx is not the first time we have explored an asteroid. Several robotic spacecraft led the way, such as the NEAR Shoemaker probe that orbited, and even landed on, the asteroid Eros.
Meet the asteroid pioneers and see what they discovered
5. The Probability of Successfully Navigating an Asteroid Field is…Pretty High
How much of what we see in movies about asteroids is fact, and how much is fiction? This video lays out the basics. (Spoiler alert: even though there are millions of them, the average distance between asteroids in the main belt is something like 1.8 million miles, or about three million kilometers.)

This unprocessed image shows features in Saturn’s atmosphere from closer than ever before. The view was captured by our Cassini spacecraft during its first Grand Finale dive between the planet and its rings on April 26, 2017.
As Cassini dove through the gap, it came within about 1,900 miles (3,000 kilometers) of Saturn’s cloud tops (where the air pressure is 1 bar – comparable to the atmospheric pressure of Earth at sea level) and within about 200 miles (300 kilometers) of the innermost visible edge of the rings.
