What is a solar system? Which planets consist of our solar system? Get the facts about the solar system and all the planets in it here. Jupiter, Earth, does Pluto still count? Find out here.
The Hubble Space Telescope has given us spectacular images of deep space objects that not only have expanded our knowledge of the Universe but shown us its beauty. Here are a few of the most spectacular deep space images HST has given us.
How knowledgeable you are about Neptune, now our eighth and last planet since Pluto was demoted? Take the challenge and test how well you know your facts!
To the ancients, planets were merely wandering points of light against a backdrop of fixed stars. The only moon they knew was that of our own Earth. With modern technology, we have seen each of these wanderers up close in all their grandeur and beauty.
Planets and planetoids, asteroids called Trojans and Centaurs, dwarf planets and plutoids, meteors, comets, extra terrestrial volcanoes and volcanoes made of ice! Moonscapes beautifully pockmarked with craters and valleys, and course, our endlessly interesting Sun! Let’s explore the solar system!
How many moons does Mars have? Generally the answer to this query is a relatively simple one: two. While investigating these two satellites, speculation of sinister artificial origins rose, along with intriguing scientific exploration. No matter what, Phobos and Deimos have fascinated generations.
Small but solid, our Earth is not only a paradise for life but also a place with remarkable physical properties. Despite its small volume, it holds the record of the densest planet in the Solar System, giving us a great opportunity to investigate the meaning of density in earth science.
John Couch Adams was a brilliant scientist who made numerous significant contributions to the field of astronomy. We will look at his life and his contributions to the field of astronomy, particularly to planetary science, the Moon and the Leonid meteor shower.
From the effects of meteorites and asteroids, to the tides and even the bizarre origin of the Moon itself – all of these are significant answers to the question: “How does studying the Moon help us learn more about Earth?".
Sedna, a very distant planetoid with a very long, eccentric orbit around the Sun, has much to tell us about the origins of the Solar System.
NASA’s Solar Probe Plus will become the first spacecraft to plunge into the Sun. It won’t enter the Sun’s surface, but its strange outer atmosphere, the corona, where the temperature is millions of degrees and the solar wind is accelerated to supersonic speeds. Perhaps Plus will tell us why.
