NASA Debuts ‘Galaxy of Horrors’ Exoplanet Posters, Just in Time for Halloween

If the many Hollywood blockbusters about extraterrestrial life and space exploration gone wrong haven’t already scared you into believing that the universe is truly terrifying, these Halloween-themed NASA posters just might do the trick.

The “Galaxy of Horrors” digital posters, styled like horror film advertisements from the 1950s, feature different exoplanets—planets that orbit stars other than the sun—and highlight what exactly makes them so frightening.

Space.com reports that on HD 189733 b, for example, sharp shards of silicate blow through the air faster than 5400 mph, which the poster describes as “Rains of Terror” and adds “It’s death by a million cuts on this slasher planet!” for emphasis.

The planets Poltergeist, Draugr, and Phobetor, found on the "Zombie Worlds" poster, orbit an undead star called a pulsar, whose core emits constant pulsing beams of radiation and makes Chernobyl seem like Disneyland.

You can also browse other inhospitable exoplanet posters on the site, including “Monster Mash,” a very hungry star that's slowly gobbling up pieces of a nearby planet; “The Twilight Zone,” featuring a planet with a surface covered in boiling lava; and “Eternal Darkness,” the darkest planet ever discovered orbiting a star—it’s less reflective than coal.

NASA’s Exoplanet Exploration Program created the posters and even paired them with a vintage-themed film trailer to further illustrate the "Galaxy of Horrors."

“I think for many people the posters are an entryway,” Gary Blackwood, the Exoplanet Exploration Program’s manager, said in a statement. “They make exoplanet science cool, and that opens a door for many members of the public—especially students—to learn more about the science behind the posters.”

You can read more about the exoplanets and download the posters in a few different sizes and formats here.

A Rare ‘Full Cold Moon Kiss’ Is Coming This Week—Here’s How to See It

Every year ends with a cold moon—the name given to a full moon that appears in December. The full cold moon that's lighting up skies in 2019 will come with a bonus spectacle for sky-gazers. As Forbes reports, a planetary "kiss" between Saturn and Venus will coincide with the last full moon of the year. Here's what you need to know about the astronomical events.

What is a Full Cold Moon Kiss?

The full moon of each month has a unique nickname associated with the time of year it occurs. A cold moon happens as temperatures drop and winter settles in, hence the name. December's full moon has also been called the long nights moon by some Native American tribes and the moon Before Yule in Europe, according to Travel and Leisure.

This year's moon will be visible the night of December 11 through the morning of December 12. On this same night, the planets Venus and Saturn will appear closer than usual in the night sky. The celestial bodies will be less than 2° apart and share a celestial longitude, a phenomena known as a conjunction or a planetary "kiss."

How to See the Full Cold Moon Kiss

During twilight on Tuesday, December 10, the bright planet Venus and the dimmer planet Saturn will arrive at their closest conjunction, 1.8° apart, above the southwestern horizon. The following evening, they'll be just .01° further away. Stick around the night of Wednesday, December 11 to catch the full cold moon, which reaches peak illumination at 9:12 p.m. on the West Coast and at 12 minutes after midnight on the East Coast.

Not planning on staying up late to see the moon reach its fullest state? Moonrise on December 11 will be just as spectacular. When the moon surfaces around sunset, it will appear larger and more reddish in color in the sky. Meanwhile, Venus's and Saturn's kiss will be visible 180º away.

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.
