Watch out, moon! On March 4 at precisely 7:25 am ET, a piece of rocket junk will slam into the moon.

Ready for an exotic vacation? How about…really exotic? Tired of tropical beaches or snow-covered mountains? Let’s go…out of this world.

We’ve all seen the movies. Tunnels cut through the red rock. Giant glass domes stretching from one end of a crater rim to another. Hydroponics. Lots and lots of hydroponics. But Mars is… a challenge.

First, take a bunch of matter. It doesn’t matter what kind – a piece of paper, some leftover gum. Then, press it, and press it, and press it some more. Don’t stop now! We’ve got a long way to go.

At first, the planet Mercury isn't much to look at. It has a surface only a mother could love, as desolate and empty as the Moon and pock-marked with crater after crater. But this planet has a secret, which has folks wanting to know more.

Even though NASA’s latest flagship instrument, the James Webb Space Telescope, is touted as the successor to the venerable Hubble, it has one major difference.

Excited by the prospects of the “UFO Report”? As a scientist, I have my doubts. But you can watch UFOS DECLASSIFED: LIVE on Discovery and Science June 30 at 8P where experts discuss what can and can't be explained.

You know that feeling--They close their eyes, purse their lips, and lean in. So you go for it. You feel the spark, the magic, and the fire of that first kiss. It’s one of the best things in the Universe.Except, of course, if you’re a star.

Sometimes you just know. Something clicks, you have a realization that this relationship isn’t right, and it’s simply time to go. It can happen to anyone, at any time, even to planets, and even billions of years ago.

That was worth the wait. Just a quick handful of months since its historic launch on Christmas Day, the James Webb Space Telescope has flown to its observing position, unfolded its delicate instruments and ultra-sized mirror, and run through a suite of checks and alignments and calibrations. The team at NASA behind the telescopes released their first batch of images from the science runs, and besides being gorgeous, they're powerful.

A long time ago, our universe was dark.It was just 380,000 years after the big bang. Up until that age, our entire observable cosmos was less than a millionth of its present size. All the material in the universe was compressed into that tiny volume, forcing it to heat up and become a plasma. But as the universe expanded and cooled, eventually the plasma changed into a neutral gas as the first atoms formed.

Something happens once you see the world from a different perspective. It's called the "Overview Effect". But what does that mean?

Exoplanets are planets orbiting stars outside the solar system, and every month seems to bring in a new batch of weird, wild, and wonderful worlds.

On behalf of Blue Origin, the opportunity of a lifetime is currently being auctioned off: the last seat on New Shepard, heading to space.

There was a time, a time long, long ago, before the first stars appeared. The universe was young then and less than a billion years old. But will the fall of light be the end of the universe?
