“Formation of the Planets” uses the nebular hypothesis to explain how the planets in our solar system developed.

Scientists have found at least three cycles in nature that can be traced back to the alignment of the planets. And while they won’t tell you anything about your love life or personality, by studying them, we can learn about our planet’s...

Last week we talked about the orbits of the Earth and our Moon. But today we're going to go a little bigger... well, a lot better. Did you know that there is a massive Black Hole at the center of our Galaxy? Or that Pluto's orbit is...

If you're in the market for a planet and size is your top priority, there's only one game in town, and that's Jupiter. Jupiter is significantly larger than all the other seven planets combined. The Romans didn't know how big it was when...

The Planets Song for kids is a science song that teaches young children all about the planets in our solar system. The Planets song helps children remember the names of the planets and their order in our solar system. The Planets Song is...

PLANETS OF OUR SOLAR SYSTEM- What are the names of the planets in our solar system? What makes each planet different? In this video, students will learn about the eight planets and the Sun.

While there is a little wiggle room, the planets in our solar system really are orbiting on mostly the same level. Why do they do that?

Meet one of the newest celestial bodies to be discovered: rogue planets, worlds that hurtle around the galaxy without any parent star. Caitlin Hofmeister explains how we found them, and where we think they might have come from.

When and how did the universe begin? A global group of astronomers wants to answer that question by peering as far back in time as a large new telescope will let us see. Wendy Freedman headed the creation of the Giant Magellan Telescope,...

How the orbit of the planets is dictated by mass and the force of gravity. Physics - Our Solar System - Learning Points. The curved path of one object around another is its orbit. Objects orbit due to the effects of gravity. The...

Learn The Planet Song about Ganymede the largest known moon in our solar system.

Between the orbits of Mars and Jupiter is a mysterious dwarf planet called Ceres. Its surface is dark and muddy, but has hundreds of patches of bright material.

This video examines details relating to the planets Jupiter, Saturn and their moons.

Let's learn about the 8 planets of the solar system!

Astronomer Jill Tarter, Director of the Search for Extraterrestrial Intelligence Institute, highlights the link between recent discoveries of numerous exoplanets and the search for extraterrestrial life.

Earth has seasons, but what about the rest of the planets in the solar system? Let’s take a tour from Mercury to Pluto and see what seasons would be like on all our planetary neighbors. Bring a sweater!

Upon viewing the Our Distant Neighbors video series, students will be able to do the following: Create a simple diagram of the sun and the orbital paths of each planet around the sun. Label each of the eight planets. Explain that the sun...

NASA is planning a new mission to Mars with the Mars Reconnaissance Orbiter, the largest spacecraft sent to the Red Planet since the 1970s. Equipped with a powerful telescopic camera, the orbiter will provide high-resolution images of...

Learn about the planets in our solar system! This video proves some fun facts about each planet that children will love. Preschoolers and toddlers can enjoy pictures and video of the planets while learning about these...

After Pluto's demotion to dwarf planet in 2006, our solar system went from having nine planets to eight. But about a decade later, some astronomers proposed there was another planet, larger than Earth, hiding in the Kuiper Belt. And in...

In this video Paul Andersen explains the parts of the Solar System; including the planets, dwarf planets, moons and asteroids. He explains how everything orbits around the Sun and how a proper understanding of this heliocentric model...

Now that we’re done with the planets, asteroid belt, and comets, we’re heading to the outskirts of the solar system. Out past Neptune are vast reservoirs of icy bodies that can become comets if they get poked into the inner solar system....

Hank regales us with the history of the telescope, and then introduces us to some folks from the team who are working on the newest telescope in the chronology - the James Webb Space Telescope, an infrared telescope due to launch in 2018.
