The annual Geminid meteor shower dazzled Earthlings around the world late Saturday and early Sunday.
Pieces of gravel and dust from a "rock comet" called 3200 Phaethon shot across the sky and lit up discussion boards from NASA.gov to Twitter — for those who could tear their eyes away long enough to type.

An online contest for data scientists has produced a great leap forward in efforts to predict when someone with epilepsy is going to have a seizure. The winning team used data on electrical activity in the brain to develop an algorithm that predicted seizures 82 percent of the time.

Signs of water currents and sediments are seen in the latest photos NASA's Curiosity rover sent home from Mars, the space agency said Monday. The images suggest "ancient Mars maintained a climate that could have produced long-lasting lakes," NASA says.
In the huge Gale Crater where Curiosity has been exploring, the water and sediment flow might have been massive enough to build a mountain — the 3-mile-high Mount Sharp — NASA researchers say. But they acknowledge that they're still working to solve the mystery of how the mountain formed in a crater.
Repair and boost the bacteria in the gut with the right food, prebiotics and probiotics, and you'll feel better and lose weight. That's the theory of Dr. Raphael Kellman of New York, author of The Microbiome Diet.

Cancer doctors want the best, most effective treatment for their patients. But it turns out many aren't paying attention to evidence that older women with early stage breast cancer may be enduring the pain, fatigue and cost of radiation treatment although it doesn't increase life expectancy.

NASA's unmanned Orion spacecraft has successfully splashed down about 400 miles west of La Paz, Mexico, in the Pacific Ocean after a liftoff, two orbits and re-entry that lasted just under 4 1/2 hours.
Orion, which could one day take astronauts to Mars, made a "bull's-eye splashdown" at 11:29 a.m. ET, mission control said, after the spacecraft endured a searing 4,000-degree Fahrenheit re-entry and was carried to the ocean surface under four giant red-and-white parachutes.

NASA's Orion spacecraft, which could one day send astronauts to Mars, is stuck on terra firma for at least another day after the space agency's mission control was unable to satisfactorily resolve a number of issues before a 9:45 a.m. ET launch window closed.

The search for the massive star explosions called supernovae is about to get a big boost. Astronomers at Caltech in Pasadena are building a new camera that will let them survey the entire night sky in three nights.
The problem with looking for supernovae is you can't really be sure when and where to look for them. Most telescope cameras can only capture a small patch of sky at a time. But the new camera, to be mounted on a telescope at the Palomar Observatory, has a much larger field of view.
If you're looking for life elsewhere in the universe, there's a lot to look at, and computers are pretty good at it. At least, they're good at analyzing the stuff you tell them -- for example, the brightness of stars in our sky.
That's what we learned from neuroscientist Dr. Seth Horowitz of Brown University; true silence is non-existent. "In truly quiet areas," he writes in his book, The Universal Sense, "you can even hear the sound of air molecules vibrating inside your ear canals or the fluid in your ears themselves."

It's now Goliath versus Goliath in the quest for an Ebola vaccine.
Until now, the two leading candidates for a vaccine to protect against the Ebola virus were being led by global pharmaceutical giant GlaxoSmithKline on the one hand, and a tiny company in Ames, Iowa, that was virtually unknown, on the other.
Reportedly, younger women of child-bearing age are paying $10,000 to freeze their eggs, hoping to preserve their viability until the women find mates, or their careers and finances allow them to become pregnant. That's just one issue addressed by Faith's guests, regular contributor Dr. Mary Jane Minkin and new guests Dr. Erin Wysong Hofstatter and Dr. Elena Ratner, all affiliated with Yale's School of Medicine.

It was the first ever landing on a comet, and it was perfect.
Unfortunately, that wasn't the end of the journey for the European Space Agency's unmanned Philae lander. After touching down on Comet 67P/Churyumov–Gerasimenko, the lander bounced off the surface and flew a kilometer back up into space.
Let's play a game. I'm going to name five things and you tell me what they are - "An Unnecessary Woman," "All the Light We Cannot See," "Redeployment," "Station Eleven," "Lila." They are the five fiction finalists for this year's National Book Award which will be given out this week. Don't feel bad if you didn't get the answer - I wouldn't have either. My connection to the nominees begins and ends with having picked up one of the five books from a table at - of all places - Whole Foods.

Everyone has days in which we wonder if much of anything works. Websites crash. Screens blink, go blank, or taunt: I'm sorry. Try later. We have an unusually high volume of calls. Download to update. Click here if you've forgotten your password.
But for a couple of hours on an afternoon this week, people got glimpses of excellence.

The European Space Agency's Rosetta mission made history this week by putting a lander on a comet. But at the same time, one of its leading scientists drew wide criticism for wearing a shirt featuring lingerie-clad women – a decision for which he apologized Friday.

Philae, the lander currently on comet 67P/Churyumov–Gerasimenko, may not be able to perform its extended mission — scientists at the European Space Agency worry that the probe may have landed in a spot too shadowy for solar panels to recharge its batteries. The ESA says it may not be able to contact the craft after Friday night.
Worries over the robotic lander's power supply prompted engineers to take the risky step of activating its drill, an operation that had been shelved out of fears that it would sap the remaining charge.

As you may be aware, there's a hot new space movie now in theaters — Interstellar. Here's the premise: It's just a little bit in the future, conditions have become pretty horrible on Earth and some astronauts head out in search of a new planet for humans to inhabit.
Polar vortex is a phrase you've probably heard a lot, but what does it actually mean?
"I think, sometimes, people sort of misunderstand the polar vortex and they think it's this giant amoeba of cold that sits over the North Pole that just gets dislodged and heads right over Chicago," said Ryan Hanrahan, meteorologist at NBC Connecticut. "That's not really what happens."
