Questions & answers maybe swapped around
tyy
"A" is for answer...
1. What causes a supernova?
A. force of gravity
Well, when a star just can't hold it together anymore and gravity makes it go "ka-boom," that's what we call a supernova. It's like the ultimate star explosion, fireworks on a cosmic scale!
2. How are nebulae and stars related? Select the three correct answers.
A. Stars form from nebulae.
A. Stars explode to form nebulae.
A. Nebulae form from stars.
It's a little bit like the circle of life, but in space. Stars can actually form from those beautiful, colorful nebulae. And sometimes, when stars reach the end of their stellar journey, they explode, creating new nebulae. It's like a stellar recycling program up there!
3. How can a planetary nebula be identified? Select the two correct answers.
A. central star remnant
Imagine this, a star reaching the end of its life and shedding its outer layers. What's left in the middle is a core so dense and hot that it glows, making it the telltale sign of a planetary nebula. Who needs GPS when you have a central star remnant to guide you, right?
4. What does it mean to characterize a nebula as diffuse?
A. Its edges do not have clear boundaries.
When we say a nebula is "diffuse," what we really mean is that it's a bit messy. It's like when you try to color inside the lines, but you end up going all over the place. Those edges just don't have clear boundaries, so it looks like someone had a painting party in space!
