There are three primary techniques for studying binary star systems. The first technique, direct imaging, allows astronomers to visually resolve both stars in the binary system when they are sufficiently separated.

Active Galactic Nuclei (AGNs) represent some of the most energetic phenomena in the cosmos. Their understanding is pivotal for astronomers, as they shed light on the dynamics at play in distant galaxies.

Black holes fascinate us all with their incredible masses, jets of X-ray radiation and "feeding" on everything they can find - including other black holes.
