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

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.

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.

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.

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.

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.

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

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.

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.

Long ago, our universe was without stars. When that first generation ignited, it completely transformed the cosmos, ripping away the veil of neutral gas that had persisted for hundreds of millions of years. This process, called reionization, is largely mysterious to astronomers. But new research is revealing that the smallest of galaxies may have played the biggest of roles.

According to NASA, "A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying." But what happens when a black hole dies?

All Stars die. Some stars go out with a bang. Some stars go out with a big bang — a supernova. And some stars are capable of something so spectacular, so rare, we don't even have a name for it yet.

Every star you see in the sky, including the sun, will someday die. It’s best to get used to that idea now, before things start to get heavy.

All planets with evidence of life please take a step forward. Not so fast, Venus.

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