Those bright women and men at NASA have done it again. This time they’ve discovered 7 exoplanets all revolving around the same distant star. The cool news is that on the cosmological distance scale it’s relatively close, only around 40-light years away — a mere 230 trillion miles or so. And, even more fascinating, three of the system’s planets are within the so-called “Goldilocks” habitable zone.
The system is named TRAPPIST-1 (Transiting Planets and Planetesimals Small Telescope). The TRAPPIST telescope in Chile originally discovered 3 exoplanets. Now, using NASA’s Spitzer Space Telescope and the European Southern Observatory’s Very Large Telescope, researchers have upped the total to 7 exoplanets.
I’m ready. Now, just need a spacecraft, and a quick one at that.
NASA’s Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.
The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water – key to life as we know it – under the right atmospheric conditions, but the chances are highest with the three in the habitable zone.
“This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life,” said Thomas Zurbuchen, associate administrator of the agency’s Science Mission Directorate in Washington. “Answering the question ‘are we alone’ is a top science priority and finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.”

You may well have noticed that my writing schedule here at theDiagonal has become a little more sporadic of late. Yes. I’ve been distracted by the needs of my post-truth project — Post*factua!ly.
The Oxford Dictionary recently made “post-truth” the word of the year, for 2016. A timely addition. They define post-truth as follows:
“Relating to or denoting circumstances in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief.”
I do agree. But, for 2017 I suspect we’ll need an even more important collection of related words: post-factual and postfactually. My definition goes as follows:
“Describing circumstances where only lies matter and all fact is meaningless.”
Please stay tuned for this important post-truth, post-factual project; and, normal service at theDiagonal will resume shortly.
What to believe about Area 51? Over the decades it has inspired hundreds of conspiratorial theories — extra-terrestrial spaceship landings, alien abductions, illegal governmental experimentation. Indeed, an entire tourist-based industry has arisen to attract myth-seekers to the Nevada desert. One thing does seem to be true: there’s a lot going on behind the barbed wire fences and security gates, and it’s probably all military.
In the middle of the barren Nevada desert, there’s a dusty unmarked road that leads to the front gate of Area 51. It’s protected by little more than a chain link fence, a boom gate, and intimidating trespassing signs. One would think that America’s much mythicized top secret military base would be under closer guard, but make no mistake. They are watching.
Beyond the gate, cameras see every angle. On the distant hilltop, there’s a white pickup truck with a tinted windshield peering down on everything below. Locals says the base knows every desert tortoise and jackrabbit that hops the fence. Others claim there are embedded sensors in the approaching road.
What exactly goes on inside of Area 51 has led to decades of wild speculation. There are, of course, the alien conspiracies that galactic visitors are tucked away somewhere inside. One of the more colorful rumors insists the infamous 1947 Roswell crash was actually a Soviet aircraft piloted by mutated midgets and the wreckage remains on the grounds of Area 51. Some even believe that the U.S. government filmed the 1969 moon landing in one of the base’s hangars.
For all the myths and legends, what’s true is that Area 51 is real and still very active. There may not be aliens or a moon landing movie set inside those fences, but something is going on and only a select few are privy to what’s happening further down that closely-monitored wind-swept Nevada road. “The forbidden aspect of Area 51 is what makes people want to know what’s there,” says aerospace historian and author Peter Merlin who’s been researching Area 51 for more than three decades.
“And there sure is still a lot going on there.”

Scientists have finally learned what book lovers have known for some time — reading fiction makes you a better person.
From Readers Digest:
Anyone who reads understands the bittersweet feeling of finishing a good book. It’s as if a beloved friend has suddenly packed her things and parted, the back cover swinging closed like a taxicab door. Farewell, friend. See you on the shelf.
If you’ve ever felt weird for considering fictional characters your friends or fictional places your home, science says you no longer have to. A new body of research is emerging to explain how books have such a powerful emotional pull on us, and the answer du jour is surprising—when we step into a fictional world, we treat the experiences as if they were real. Adding to the endless list of reading benefits is this: Reading fiction literally makes you more empathetic in real life.
Not all fiction is created equal, though—and reading a single chapter of Harry Potter isn’t an instant emotion-enhancer. Here are a few key caveats from the nerdy scientists trying to figure out why reading rules.
Rule #1: The story has to “take you somewhere.”
How many times have you heard someone declare that a good book “transports” you? That immersive power that allows readers to happily inhabit other people, places, and points of view for hours at a time is precisely what a team of researchers in the Netherlands credit for the results of a 2013 study in which students asked to read an Arthur Conan Doyle mystery showed a marked increase in empathy one week later, while students tasked with reading a sampling of news articles showed a decline.
