Scientists have updated their forecast for the current solar cycle, which usually lasts about 11 years. Solar activity is now expected to peak earlier and to be stronger than previously thought.

In Alburgh, atop a hill in an orchard of plum and apple trees, dozens of people peer through giant telescopes during this annual — and spur-of-the-moment — event.

Three rockets will launch from the desert of New Mexico this Saturday as part of a NASA mission to better understand the upper atmosphere.

The annual Perseid meteor shower graces the night sky this time of year. Its peak is coming up, and meteorologist Mark Breen shares his meteor-gazing tips.

Jack Duranceau’s senior thesis studied the existence of two new planets 257 light years away.

Over the next couple of nights, five planets are expected to align in the sky. And you won't even need a telescope to see them (although binoculars will help).

The two brightest planets in Earth's night sky are millions of miles apart. But due to an astronomical quirk, they appear to be engaging in a cosmic dance tonight. Now that's a moment of awe.

There was no reason for alarm, as a NASA engineer called it "one of the closest approaches by a known near-Earth object ever recorded." It was only 2,200 miles above the Earth's surface.

Comet C/2022 E3 was first spotted last year. Its path will bring it within 26 million miles of the Earth on Wednesday, allowing it to be visible to the naked eye for perhaps the last time ever.

Jupiter will be some 367 million miles from Earth on Monday, the closest it's been since 1963. It coincides with Jupiter being on the opposite side of Earth from the sun — when it'll be its brightest.
