The comet made its first documented pass by Earth this month and is likely to disappear from our night sky for 80,000 years -- that is, if it survives its voyage around the solar system.

A Supermoon is gracing our skies on Thursday night, and it's going to be a showstopper. The Hunter's Moon, the largest full moon of the year, will shine brightest after sunset.

An icy comet that will take 80,000 years to return – if it survives the trip – is streaking across the sky this October. 

A rare comet that won’t be seen for another 80,000 years is visible in the night sky through part of October.

Look up this week - the moon is set to appear full most nights. Here's why.

Comet Tsuchinshan-Atlas made its closest pass to Earth this weekend, but weather permitting, it should be visible to the naked eye until the end of October. Here's what to know.

The geomagnetic storm this week helped make the aurora incredibly vibrant, and brought Northern Light displays to much of the northern U.S.

A severe geomagnetic storm is forecast at the same time Hurricane Milton is forecast to strike Florida.

The X9.0 flare takes the crown from the previous strongest flare of Solar Cycle 25, which was an X8.7 flare on May 14.

A massive solar flare could trigger auroras in the coming days. Here are the chances of seeing them in the United States.
