For those who contemplate the cosmos, each year is another exciting spectacular space show. In January, NASA's New Horizon's spacecraft flew by Ultima Thule, an object in the Kuiper Belt some 4 billion miles (6.4 billion kilometers) from Earth, and sent back pictures of a bizarre miniature world shaped like a bowling pin. In the days and months ahead, we'll be gazing in wonder at more images and other data from New Horizon, as it continues its exploration of that mysterious realm, which may contain secrets about the origin of the solar system. Not quite two days later, a Chinese probe, Chang'e-4, became the first spacecraft to ever land on the far side of the moon.
But that was just the start. Here are some of the key events, from meteor showers to space exploration milestones, that we can expect this year.
