First-Ever Map of Titan Reveals That Saturn’s Moon Is a Lot Like Earth

If there's any life in this solar system outside Earth, we likely won't find it on Mars or even on another planet. Saturn's moon Titan is the place in our celestial neighborhood that's most similar to our own home, and it's where scientists think we have one of the best chances of discovering life. Now, as Nature reports, newly visualized data shows just how much Titan has in common with Earth.

Between 2004 and 2017, the NASA spacecraft Cassini performed more than 100 fly-bys of Saturn's moon. Titan is unique in that it's the only moon in the solar system with clouds and a dense, weather-forming atmosphere. This has made it hard to study from space, but by flying close to the surface, Cassini was able to capture the landscape in an unprecedented level of detail.

NASA's new map of Titan, published in the journal Nature Astronomy, reveals a varied world of mountains, valleys, plains, and sandy dunes that starkly contrast with the desolate wastelands we've seen on neighboring planets. It's also home to seas and lakes, making it the only place in the solar system other than Earth with known bodies of liquid. But instead of water, the pools mottling the moon's surface consist of liquid methane.

Even with its Earth-like geology and atmosphere, chances of finding life on Titan are still slim: Temperatures on the surface average around -300°F. If life does exist there, it's likely limited to microbes in the moon's craters and icy volcanoes.

It will be a while before NASA is able to study Titan up close again: NASA's next drone mission to the body is set for 2034. Until then, scientists have plenty of data recorded by Cassini to teach them more about how the moon formed and continues to change.

LEGO Is Launching an Official International Space Station Set

Not everyone can live out their childhood dreams of floating around in space aboard the International Space Station, but now you can at least construct a toy version of it for your own house.

Next month, LEGO is releasing an impressive model of the International Space Station as part of its Ideas program, which produces designs that were suggested by fans. This one was submitted three years ago by Christoph Ruge.

According to TechCrunch, the kit includes the ISS, a dockable space shuttle, two astronaut figurines, and a satellite that you can “deploy” with the robotic Canadarm2 (which is used to capture and repair satellites on the ISS). It also comes with a display stand, so you can make it the eye-catching centerpiece of your coffee table if it happens to match your living room decor.

The ISS might not look as formidable as the life-size model of astronaut Buzz Aldrin that LEGO builders created last year, but that doesn’t mean it’s not difficult to construct—the 864-piece set is labeled for kids ages 16 and older.

Having said that, it doesn’t mean that younger kids can’t help out with the assembly, or at least play with it once it’s complete. At about 7 inches high, 12 inches long, and 19 inches wide, the station could inspire the next generation of space explorers.

The $70 kit will be available on February 1 in LEGO stores or the LEGO website.

A Snow Moon Will Light Up February Skies

February is the snowiest month of the year in many parts of the U.S., but on February 9, consider braving the weather outside to look up at the sky. That Sunday morning, the only full snow moon of the year will be visible. Here's what you need to know about the celestial event.

What is a snow moon?

If you keep track of the phases of the moon, you may already know that the full moon of each month has its own special name. Following January's wolf moon lunar eclipse is a snow moon in February. The name snow moon is said to have originated with Native American tribes, and it refers to the heavy snowfall that hits many parts of North America in February.

According to The Old Farmer's Almanac, different tribes had different names for February's full moon. The Wishram people named it the shoulder to shoulder around the fire moon and the Cherokee people called it the bone moon because animal bones were sometimes their only source of nutrition in the dead of winter. Snow moon is the name that's most commonly used by almanacs today.

When to See the Snow Moon

The moon will enter its next full phase the morning of Sunday, February 9. The snow moon will be at its fullest at 2:34 a.m. EST, but if you're not willing to stay up that late, it's still worth looking up. The previous evening—Saturday, February 8—the moon will be 99 percent illuminated on the East Coast. Check your local weather forecast and find a spot with clear skies to get the best view of the wintertime spectacle.
