These Spectacular Wave-like Clouds Are The Result Of The Kelvin-Helmholtz Instability. When Two Layers

These spectacular wave-like clouds are the result of the Kelvin-Helmholtz instability. When two layers of air move past one another at different velocities, an unstable shear layer forms at their interface. Disturbances in this shear layer grow exponentially, creating these short-lived overturning waves that quickly turn turbulent. The strong resemblance of these clouds to breaking ocean waves is no coincidence–the Kelvin-Helmholtz instability occurring between the wind and water is what generates many ocean waves. Kelvin-Helmholtz patterns are also common on other planets, like Jupiter, Saturn, and Mars. (Image credit: Breckenridge Resort; submitted by jshoer)

I always get asked if I’m pro-choice. And I say yes. Then I get asked if I would ever have an abortion and again I say yes. And people are usually shocked by how open I am about it. But I am a children’s advocate. I’ve seen kids whose parents have had them too young. I’ve seen kids who are in foster care and children’s homes because of neglect and abuse. I’ve seen teen moms struggle and single dad’s. If I am not financially stable, mentally stable, or emotionally stable. I should not and I will not have children. I believe in the morning after pill, condoms, pulling out, and birth control. I can tell you when I am ovulating and can get pregnant and when I am not.

I am responsible. I am prepared. And if I were to get pregnant I am pro-choice.

My aunt put her child up for adoption. Her stance was basically to let her have a chance at a happy life even though she herself couldn't give it to her. I don't think there's anything wrong with that at all.

I mean good for her, but you do realize that we have an issue of not enough kids being adopted. So they end up in the foster care system.

10 “Out of This World" Facts About the James Webb Space Telescope

Wouldn’t it be neat to see a period of the universe’s history that we’ve never seen before? That’s exactly what the James Webb Space Telescope (JWST) will be able to do…plus more!

image

Specifically, Webb will see the first objects that formed as the universe cooled down after the Big Bang. We don’t know exactly when the universe made the first stars and galaxies – or how for that matter. That is what we are building Webb to help answer.

Here are 10 awesome facts about this next generation space telescope:

1. The James Webb Space Telescope is the world’s largest and next premier space observatory. It will extend the discoveries of the Hubble Space telescope and observe the birthplaces of stars, galaxies, planets and life over billions of years.

image

2. It is named after James Webb, NASA’s second administrator and champion of our science.

image

3. At 3 stories high and the size of a tennis court, it will be 100 times more powerful than Hubble!

image

4. It is so big that it has to fold origami-style to fit in the rocket, which is only 5.4 meters wide…And then it will unfurl, segment by segment, once in space.

image

5. The telescope will observe infrared light with unprecedented sensitivity. It will see the first galaxies born after the Big Bang over 13.5 billion years ago.

image

6. Webb’s infrared cameras are so sensitive they must be shielded from light from the sun, Earth, and moon. The 5-layer sunshield is like having sunblock of SPF 1 million.

image

7. Webb will orbit the sun 1 million miles from Earth, where the telescope will operate at temperatures below -390 F (-235 C).

image

8. Webb’s mirrors are coated with a super thin layer of gold only about 1000 atoms thick to optimize their reflectivity in the infrared.

image

9. Webb will launch from French Guiana in 2018. It is launched near the equator because the faster spin of Earth there gives the rocket an extra push.

image

10. Webb is an international mission, with contributions from the European Space Agency and Canadian Space Agency. Once operational, scientists from all over the world will be able to use Webb to explore our solar system, planets outside our solar system, stars and galaxies.

“Pro-lifers” should be forced into adopting one of the many foster children already in need of a home. This puts them into the same position as the women they try to force into pregnancy/birth.
