Star Systems and Types of Galaxies
We've learned a lot about stars! We know how they form, and we know that most of them exist in galaxies. But how are they arranged within galaxies? And are there different types of galaxies or are they all the same? There is a lot to...

NASA | Swift Finds 'Missing' Active Galaxies
Most large galaxies contain a giant central black hole. In an active galaxy, matter falling toward the supermassive black hole powers high-energy emissions so intense that two classes of active galaxies, quasars and blazars, rank as the...

Gravitational Lensing: What It Is And How It Is Helping Us Discover New Galaxies
Gravitational lensing occurs when a huge amount of matter, like a star, galaxy, or cluster of galaxies, creates a powerful gravitational field around it, strong enough to bend the light coming from distant galaxies (behind them). Roots...

NASA | NASA's Fermi Shows How Active Galaxies Can Be
Active galaxies called blazars make up the largest class of objects detected by Fermi's Large Area Telescope (LAT). Massive black holes in the hearts of these galaxies fire particle jets in our direction. Fermi team member Elizabeth Hays...

How is it possible to measure the distance to stars and galaxies?
We can't use tape measures, rulers or lasers to measure the astronomical distances to stars and galaxies, so how do we do it?

Quasars and Early Galaxy Formation
One type of object that some astronomers study is called a quasar. When these were first discovered, it was a bit confusing as to precisely what they are, which is why quasar stands for quasi-stellar object, since we thought they looked...
