APOD #2: Venus in Retrograde

Occasionally, Venus appears to be moving backwards in the sky. "Appears" is the key word here, because, technically speaking, no planet actually moves backwards in their orbits around the Sun. In fact, they don't even slow down. Retrogrades are essentially illusions that result from our point of view from Earth, simply because the Earth is also orbiting the Sun at a different speed than the other planets. Venus is Retrograde approximately 40-43 days every 18 months.

If you believe in astrology, be careful of what you try to do when Venus is in retrograde! 

APOD #1!

"This new Hubble image is centered on NGC 5793, a spiral galaxy over 150 million light years away in the constellation of Libra. This galaxy has two striking features: a beautiful dust lane, and an intensely bright center." - phys.org

APOD, or astronomy photo of the day, takes a look at what is happening in the universe around us through photos. Submissions ARE WELCOME AND ENCOURAGED. A photo that qualifies is anything having to do with outside our atmosphere. Photos can be current, but don't have to be.

EXTRA EXTRA!! IS THERE LIFE AT THE MID-OCEAN RIDGES??

A hydrothermal vent found near Antarctica. (source) 

MID-OCEAN RIDGES are located all across the Earth's crust, but majority of them are found deep in the ocean. They are the points where HOT LAVA  is escaping from the mantle, and new crust is slowly being formed. But, the question is, can life be found at these extremely hot, dark points in the earth's oceans?? 

Watch all or some of this TED TALK, and then answer the following questions in the form of a paragraph: 

1. What is a hydrothermal vent and where are they found? 

2. What marine species can be found at the mid-ocean ridges? 

3. Describe the surface of the bottom of earth's oceans. 

share your paragraph with me anytime before the end of the trimester: emily.elpuente@gmail.com 

Class 11/18

Today we began exploring HOW convection currents move in the mantle.

 

What is constantly in motion in this diagram? See if you can identify the variables first, before clicking on the link here and seeing if you are correct!
