The Space Between Planets

The Space Between Planets

Have you ever really sat down to think about how much space there is in the universe? It’s pretty inconceivable, but there are some useful tools that can help put things in perspective. You’ve already seen a scale model of our solar system by mass, so here is a model of the space between our

The Geminid Meteors

The Geminid Meteors

Nothing is more exciting than looking up and seeing a shooting star streak across the night sky. But we all know it’s not really a star falling from the heavens, but rather a giant ball of rock, ice and dust skimming through the atmosphere. This December we will be able to witness one of the

A Planet Size Comparison

A Planet Size Comparison

A planet is an astronomical body orbiting a star or stellar remnant that: is massive enough to be rounded by its own gravity, not massive enough to do fusion, and has cleared its neighboring region of planetesimals. Our star (the sun) has 8 planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Though these

Look up and Constellations

Look up and Constellations

A constellation is a group of stars that are considered to form imaginary outlines or meaningful patterns on the celestial sphere. They typically represent animals, mythological people, gods or creatures. There are 88 modern constellations, but just because those are the ones that are recognized doesn’t mean that one you make up is less valid.

Looking Back At Cassini

Looking Back At Cassini

NASA’s Cassini orbiter will be ending its mission with a grand finale dive into Saturn’s atmosphere on September 15, but it’s accomplished so much in its nearly 20 years of operation. When it was first launched on October 15, 1997, it was the first mission to be an in-depth study of Saturn and its moons.

The Life and Death of Stars

The Life and Death of Stars

Did you know that stars live and die just like other living things?…Okay, maybe not just like them. But they do have a beginning, middle, and end. All stars start out the same way, from a nebula. A nebula, otherwise known as a “star nursery”, is a cloud of gas and dust out in space. Nebulae

Gravitational Lensing

Gravitational Lensing

Most of us have experienced using a lens in some way, whether it was using glasses, cameras, or our favorite, telescopes. A lens is a piece of glass or other transparent substance with curved sides for concentrating or dispersing light rays. They have the ability to bend light! Did you know that gravity can bend light

You Are Here: Our Place In Space

You Are Here: Our Place In Space

Spend a clear night outside and you might notice something strange about the sky: the stars migrate from horizon to horizon. It’s not quite as obvious as the sun’s motion, but it’s true. Our home star isn’t the only one that appears to rise in the east and set in the west. Image credit: Pearson

The Greatest Telescope That Almost Wasn’t

The Greatest Telescope That Almost Wasn’t

Why put a gigantic telescope in space? It’s a common misconception that Hubble was placed in orbit to be closer to the stars. Really, the difference in distance between our planet’s surface and low Earth orbit is negligible compared to how far away Hubble’s research targets are. The great advantage of a space telescope is

How Many Stars are Out There?

How Many Stars are Out There?

The numbers used in Astronomy are truly staggering.  For starters, the Earth is about 25,000 miles around. The nearest star to us is–obviously–the sun, which is 93 million miles away. To travel that distance, you would have to circle the Earth nearly 4000 times! The larger the numbers get, the harder it gets to understand
