Stunning pictures posted online show Comet ISON lit up like a beacon as it edges ever closer to the sun.
And keen astronomers are continuously catching glimpses of the bright, icy rock with telescopes and binoculars.
Appearing as a fiery ball of bright blue and green, it leaves a long wispy tail behind it in the starry sky.
The comet is expected to pass as close as 1 million km from the sun's fiery surface on November 28, and if it isn't destroyed, be visible to the naked eye from early December.
But it is already shining brightly and some people may be able to see it as a tiny speck on a clear night.
Karl Battams, of Nasa’s Comet ISON Observing Campaign, wrote on his blog: "The problem is that we don’t yet know why ISON has so suddenly and dramatically changed in brightness and production rates."
If the 2,760 degrees C temperatures don't melt it away, or the strong gravitational field doesn't pull it apart, people in the Northern Hemisphere will get the best view.
