A bright comet visible in December provides an excellent viewing opportunity for night sky lovers – even potentially with the naked eye.
The other galaxies are there, but they are hiding a very long way away.
We are in the Milky Way. If you travelled on an extremely fast spaceship for more than two million years, you would reach our neighbour, the Andromeda galaxy. All other galaxies are even further away.
About a century ago, we didn’t even know that galaxies existed.

Pretty much as soon as we understood what galaxies were, we realised they are all moving away from each other. And the ones that are further away are moving faster. In short, the universe is expanding.
The ISS sees us on Earth, but look up at night and you may see it, too.
A couple thousand satellites are orbiting Earth right now. Under the right conditions, your naked eye can spot these human-made objects in the night sky.
As long as clouds don’t get in the way, the view should be spectacular.
A bunch of uncommon things all happening at the same time mean this full moon will have some special attributes.

A Darwin mechanic's success in the hunt for new exoplanets shows how amateur and professional scientists can work together on new research.
Astronomers predict the existence of Planet 9 based on data collected in the outer Solar System.
To help find Planet 9, you just need a computer and a little astronomy knowledge. Already, 120,000 images have been processed by citizen scientists in just 3 days.
Enjoy the full moon’s glow.
Full moons are good reason to look up – and the one on Nov. 14 is no exception. But here’s why you likely won’t see something shockingly different from other full moons you've observed over the years.
All is not calm in the cosmos.

Stargazing seems such a quiet, calm activity. But whether our eyes can see or not, those stars out there are in constant flux. Time-domain astronomy studies how cosmic objects change with time.
A telescope can open up on the wonders of the heavens.

Stargazing in your back yard or on a camping trip can amaze and inspire. If you're thinking of buying a telescope, here are a few key things you should look out for.
