Explore the vast reaches of space and mankind’s continuing efforts to conquer the stars, including theories such as the Big Bang, the International Space Station, plus what the future holds for space travel and exploration.
Hundred of meteors fly across the sky every night, but only a few make it to Earth. Meteors are best known for the brilliant streaks of light they make as they burn up in the atmosphere. Learn about 10 memorable meteor crashes that left an impression.
Less than 100 miles from Las Vegas, is the most famous secret military installation on the planet: Area 51. For decades, the U.S. government refused to acknowledge it existed. But now, the secret is out.
Bill Cooke, NASA scientist, is regularly shooting marbles into carefully arranged piles of soil. Why is NASA paying this man to do something most of us would do for free? It's all about our return to the moon.
From a distance, a space shuttle looks pretty sturdy. It's enormous and solid, and it can withstand extreme temperatures when it enters the Earth's atmosphere. But in some ways, a space shuttle is delicate.
But can a commercial spacecraft take off on its own from the ground, travel into outer space and land again on a runway? That's the goal of XCOR Aerospace, and it starts with the EZ-Rocket. In this article, we'll learn about the technology behind the EZ-Rocket and see how XCOR plans to expand on this technology in the future.
NASA needs a vehicle capable of carrying crew and payloads to Earth orbit, the moon and Mars. Learn about the technologies of the new Crew Exploration Vehicle and find out how it will help us explore the moon and beyond.
Some of the most interesting objects in our solar system are also the smallest or largest. In addition to the sun, planets, and moons, our solar system has a variety of small objects such as asteroids, comets, stars, meteors, and moons. These have affected what has happened on Earth in many ways.
Jupiter is the largest planet and is fifth from the sun. It is the third-brightest spot in our skies--after the sun and Venus. Jupiter is made up almost entirely of gas, which means it doesn't have a solid surface like Earth does.
Mercury is the closest planet to the sun, and it is the second smallest. It is the fastest-moving planet, so it was named after the Roman god of speed. Like Earth, it is a terrestrial planet, meaning it has a solid surface that you could land on.
Our planet Earth is part of a solar system that consists of nine (and possibly ten) planets orbiting a giant, fiery star we call the sun. For thousands of years, astronomers studying the solar system have noticed that these planets march across the sky in a predictable way.
Neptune is the eighth planet from the sun, the fourth largest, and a gas planet. It is named after the Roman god of the sea. Neptune is four times the size of Earth, and its day lasts a little more than16 hours. Its year is about 165 Earth years. Neptune's orbit is a perfect circle. The last stop on spacecraft Voyager's epic trip through the solar system was the gas giant Neptune.
