Scientists Profiles
What do all scientists have in common? No, it is not that they wear pocket protectors or are geeks. It is that they all ask questions. Lots and lots of questions, since asking questions about what you see is one way to figure out how things work. Here at NASA's Goddard Space Flight Center, there are lots of people working towards a better understanding of the Universe around us. However, it is not always clear how particular observations can shed light on how our Universe works. Have you ever wondered how scientists work to understand the things in the skies around us? Have you ever wondered what the rocket scientists at NASA DO at work all day? Or how they spend their weekend?
To give you an idea about the people who are the scientists here and the kinds of research they are pursuing, we have put together some profiles for you. There will be a new scientist featured about once a year...but old scientists never die, they just move to the archive!

<p>As a vocal advocate for diversity in the space industry, Luckey emphasizes the importance of community and mentorship within NASA and beyond. “I try to reach out to people and build that community because it is important,” she said. “That’s one of the things that keeps people coming to work &#8211; no matter where you work. It’s not the work, it’s the people that keep you coming back. I work with a lot of great people that have built that NASA community.”&nbsp;</p>

These objects aren’t really holes. They’re huge concentrations of matter packed into very tiny spaces. A black hole is so dense that gravity just beneath its surface, the event horizon, is strong enough that nothing – not even light – can escape. The event horizon isn’t a surface like Earth’s or even the Sun’s. It’s a boundary that contains all the matter that makes up the black hole.There is much we don’t know about black holes, like what matter looks like inside their event horizons. However, there is a lot that scientists do know about black holes.Unable to render the provided sourceFinding Black HolesBlack holes don’t emit or reflect light, making them effectively invisible to telescopes.

How Many Solar Systems Are in Our Galaxy?

The Short Answer:

	Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy.
	

Our solar system is just one specific planetary system—a star with planets orbiting around it. Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy. That’s just how many we’ve found so far. There are likely to be many more planetary systems out there waiting to be discovered!
Our Sun is just one of about 200 billion stars in our galaxy. That gives scientists plenty of places to hunt for exoplanets, or planets outside our solar system. But our capabilities have only recently progressed to the point where astronomers can actually find such planets.

In this illustration, you can see three young planets tracing orbits around a star called HR 8799 that lies about 130 light-years from Earth. Image credit: Gemini Observatory Artwork by Lynette Cook

Why is it hard to find planets outside our solar system?
Even our closest neighboring stars are trillions of miles away. And all stars are enormous and extremely bright compared to any planets circling them. That means that picking out a planet near a distant star is like spotting a firefly right next to a brilliant lighthouse miles away.

Spotting an exoplanet around a faraway star is like spotting a firefly next to a lighthouse. The light from the lighthouse is so bright that you would have a hard time spotting the flicker of a firefly. In the same way, all stars are bigger and staggeringly bright compared to the planets orbiting them.

What is it like in other planetary systems?
So far, the planets outside our solar system have proven to be fascinating and diverse.
