About Emma

I'm a college student, astronomer, writer, Democrat, global warming activist, hardcore trekkie, daring adventuress, and dreamer. I have four blogs to date. The primary one is Science at Your Doorstep, but I also post to The Sojourns of Star Trek, Common Sense Politics (US), and Toleventures. I guest post to A Momma's View. I write for different reasons. Sometimes because I want to share my process of discovery with others. Sometimes because I think a story is too incredible to keep it to myself. Sometimes just because I want to be heard. Regardless, I hope you enjoy it!

Radio Astronomy: Limitations

Radio Astronomy

Ever seen one of these before? Yeah, it’s a bit bigger than your average radio antenna. That’s because its job isn’t to direct radio signals to your house. It’s a radio telescope, and its job is to collect as many radio … Continue reading

Interferometry

Imagine you have an image like this. This object is faint and faraway, so you can’t make out much more detail. You know that other stars like it—closer, brighter stars—have looked like this and turned out to be two stars, … Continue reading

A Telescope Tour

For the past few days, I’ve done a lot of talking about differences between types of telescopes and mounting systems. On occasion, I’ve mentioned some of their parts, though I haven’t focused on that. Today, I will. This post is … Continue reading

Improved Telescope Mounting

So, any idea what this handy-dandy thing is? Okay, so maybe I sort of gave it away in the post title… I know what you’re about to say next. Why are we looking at a mount? What’s so special about a … Continue reading

Improved Telescope Mirrors

When it comes to telescopes, bigger is always better. Bigger means more light-gathering power and better resolution. And a longer telescope—meaning, a longer focal length—can actually do wonders for your magnification power. Light-gathering power, by the way, just means how much … Continue reading

Improved Reflecting Telescopes

Can you tell the difference between these two telescopes? I’ll give you a hint. They are both reflectors. I know I wrote before that you’ll normally find the eyepiece (the little bit tacked onto the telescope tube) on the side with … Continue reading

Light Pollution

This photo was taken at night. Seriously. At night. But…it looks too bright for the night. I’ll bet I wouldn’t even have to shine a flashlight to see my way around here. Need proof? Here’s New York City during the … Continue reading
