Comet ISON 2013: If you miss Pan-STARRS, don't worry, Comet ISON is coming

After last night, Comet PAN-STARR is only be visible by telescope.

But don't worry. If you miss Pan-STARRS, we might get to see a better comet later in 2013: Comet ISON.

ISON was discovered by Russian astronomers Vitali Nevski and Artyom Novichonok in September 2012. It is named after their night-sky survey program, the International Scientific Optical Network.

On November 28, it is expected to dive into the sun's atmosphere. If it survives, it might glow as brightly as the moon and be briefly visible in daylight. Its tail might stretch far across the night sky. Or it could fall apart.

Scientists say they won't know until late summer what to expect from ISON.
