This Super-Efficient Lightbulb Uses Tesla Tech For An Incandescent Glow

Despite their inefficiency, old-school incandescent lightbulbs sure did put out a pleasant, natural-looking light. The folks at Finally Light Bulb missed that light, so they brought it back with an efficient, affordable bulb using technology Nikola Tesla once patented. The team visited our offices to show us the light.


How NASA Uses The Full Moon To Calibrate Its Earth-Gazing Satellite

The full moon — like this weekend’s glorious Super Moon event — is a great show for us here on Earth. But for NASA, it also plays a critical role in keeping its Landsat 8 satellite working properly. How? By using the moon exactly like a photographer uses a light meter.


Scientist Find That 80% Of All Light In The Universe Is Missing

According to observations made by the Cosmic Origins Spectrograph on board the Hubble Space Telescope, the Universe is missing 80 per cent of all its light. Astronomers are completely baffled: “We still don’t know for sure what it is, but at least one thing we thought we knew about the present day universe isn’t true.”


This Is How Light Travels Through The Layers Of The Sun

NASA’s Goddard Space Flight Center released this pretty neat animation back in 2012, which shows how light streaming up from inside the sun through its many layers. Did you know that the light that shines on our Earth takes some 40,000 years to travel through the sun’s layers? I did not, and now I am amazed.


The Breathtaking Beauty Of Los Angeles At Night

Has Los Angeles finally found an answer to the title sequence of Woody Allen’s Manhattan? Revealing the beauty of nighttime Los Angeles in all its glory, Colin Rich’s mesmerising time lapse video “City Lights” plays off the interaction between two kinds of night light: the twinkling stars above the horizon and the pulsating city below.


Magic Material Is Both A Reflecting Mirror And A See Through Window

No, it’s not a one way mirror. It’s much cooler than that. MIT scientists have invented a new invisible mirror that can show reflections like a typical mirror but also be see through like a window. The magic is in the alternating 84 ultra thin layers typical glass and tantalum oxide. It’s a mirror but when you spin it, it becomes transparent. Some light passes through, some light gets reflected.


Using X-Rays To Peer Inside Ancient Art Objects

Photographer David Maisel — widely known for his incredible aerial work, including a breath-taking project recently shot in Spain — has opened a new show in New York exploring the otherwise invisible insides of culturally important art objects. Called History’s Shadow, it is on display at the Yancey Richardson Gallery until 10 May 2014.


Walk On A Magic Carpet Of Light In This Moroccan Cathedral

Watch out, the ground will change beneath your feet at the Sacré Coeur in Casablanca. As part of the installation Magic Carpet 2014, an interactive light show swirls, swarms and shimmers under the cathedral’s vaunted arches. It’s even more thrilling to watch the lights in action in the video below.


A Simple Photographic Trick Lets You See Invisible Things

The world is full of things you can’t see: the heat coming off your hand, the spray of a sneeze, even the sound of two hands clapping. But a simple camera trick called Schlieren flow visualisation turns those invisible waves of light into beautiful plumes of movement. With this trick you can literally see invisible things.


Weird, Bright Light Spotted On Mars

Do you see it? There’s a little beacon of light in the photograph of Mars above. It’s on the left side of the photo, and it’s pretty darn bright. What could it be? More importantly, what do we want it to be? A Martian signal keeping track of the Curiosity rover? An alien laser beam? A key to a secret portal in the universe? A superhero?
