The Small Magellanic Cloud - also known as the SMC - is one of the closest galaxies to the Milky Way.

Our Sun is a star. In fact, it is the closest star we'll ever see. The Sun is about 5 billion years old and will live for about 5 billion more. But not all stars live this long.

Over 400 years ago, Johannes Kepler and many others witnessed the appearance of a new "star" in the sky.

In 1604, a new star appeared in the night sky. It shone brighter than all the other stars, and for three weeks, it was even visible during the day!

Neutron stars are the ultra-dense cores that are often left behind after massive stars run out of fuel and collapse.

Stars appear to be permanent fixtures of the night sky. However, stars are like people. They are born, live a lifetime, and ultimately die.

The supernova remnant known as W49B is, let's say, a bit unorthodox looking. Many supernova remnants appear rather spherical in shape.

One star, eight planets, and a myriad of moons, comets and asteroids. This is the Earth's local neighborhood, known as the Solar System.

While astronomers know that Cassiopeia A, or Cas A for short, is the aftermath of a massive star that exploded, it is unclear exactly when the explosion took place.

DEM L50 is what astronomers call a superbubble. These objects are found in regions where massive stars have formed, raced through their evolution, and exploded as supernovas.
