What Are We Learning From Looking Out To Space? | Ever Wondered | Spark

In this week’s explosive episode we’re looking upwards, way, way up, beyond the clouds, the stars and our very own galaxy, into the wide blue yonder to unearth just what it is that we already know and what we are yet to discover about the science of space.

If everyone would just put more in the recycling bin instead of the trash can, the world would be a better place. Right? Well, that’s not exactly true. For many items that end up in the recycling bin, you’ve actually created more trash by trying to recycle them. You’ve also made it harder to recycle the stuff that CAN be saved, and basically demonstrated that recycling is broken… at least the way we do it today. Here’s how we can fix it.

What can you recycle? Some helpful links:

Superfetation: When You Get Pregnant… Even Though You’re Already Pregnant

The process of human baby making seems pretty straightforward: egg+sperm+time=baby. But hold on to your ovaries, folks! It’s pretty rare, but sometimes, days or weeks after a person gets pregnant, they can get pregnant again in a process called superfetation.

Alien Planet Count Passes a Thousand Documentary – What are Exoplanets and How do We Find Them

Our Milky Way Galaxy is teeming with exoplanets—statistically speaking at least one for each of the hundreds of billions of stars in the galaxy. Thousands of planets have been discovered, with thousands of more planet candidates identified. Several different planet-finding techniques have matured and contribute to our present knowledge of exoplanets. Each technique has different sensitivities that favor a planet-star separation and planet mass or size range limits. Because of the selection effect, none of the current exoplanet-finding techniques can find solar system copies. Astronomers have nonetheless found a completely unexpected diversity of exoplanets, a veritable “zoo” containing many astonishing planet types.

Take A Journey Into The Center Of The Galaxy – How Do You Find Exoplanets?

We live in the Milky Way Galaxy, which is a collection of stars, gas, dust, and a supermassive black hole at it’s very center. Our Galaxy is a spiral galaxy, which are rotating structures that are flat (disk-like) like a DVD when looked upon edge-on. There is also a bulge in the middle that consists of mostly old stars. When you look at a spiral galaxy face-on, you can see beautiful spiral arms where stars are being born. Our solar system is in the Orion arm, and we are about 25,000 light years (2.5 X 10^17 miles) from the very center of the Galaxy.
