This is where I post about all the things in Science that I find interesting.

 

Upper atmosphere sprites. 
Sprites are the result of a thundercloud discharging upwards into the Thermosphere. They are triggered by positively charged lightning between a thundercloud and the ground.

The “Wow!” signal. 
On August 15th, 1977, the Big Ear Telescope of the Ohio State University was working on a SETI (Search for Extra-Terrestrial Intelligence) project, listening in on the frequency of Hydrogen.
As hydrogen is the most abundant element in the Universe it would make sense to assume that any other alien civilization attempting to contact our own would broadcast at this frequency.
For 72 seconds on that night, from a location 122 light years away, near the star Tau Sagitarii, a signal was interpreted by that telescope at this frequency.
The signal was unlike any other that could be created in nature, and to this day scientists have been unable to explain what it was.

Atlas rocket launched from the Kennedy Space Centre breaking the sound barrier.
As an object breaks the sound barrier the different pressure differentials surrounding the object can actually bend light, which is what creates the ripples surrounding the rocket in the gif above.

By using simple household equipment and a speaker playing a constant 24Hz frequency, it is possible to make water form itself into a Sin Wave.

Tonight (August 20th) is a blue moon.
Despite the name (and my picture) the moon itself doesn’t turn blue, but is instead the 4th full moon in a 3 month period.

As one of the meteors from the Perseid Meteor Shower entered the atmosphere it ionized the air molecules, making them glow.
Resulting in these rainbow traces across the sky

A team of researchers from the Colorado Boulder University have got closer to what is considered the Holy Grail of renewable energy, splitting water with sunlight. 
If discovered it would hold the potential to split hydrogen atoms away from the oxygen atoms in a water molecule to fuel hydrogen cells. 
This discovery could lead one day to massive Hydrogen farms as shown in the concept photo above.

The Carina Nebula, as photographed here by the ESO VLT Telescope is a large bright nebula located between 6500 and 10000 light years away from Earth. 
4 times larger and brighter than the much more famous Orion Nebula it contains multiple massive and luminous stars, such as the hypergiant star - Eta Carinae.

Footage from the side mounted camera on board the Huygens probe that in 2005 landed on Titan, the largest moon of Saturn. 
The smooth rocks from this alien world show that erosion has occurred, a sure sign of running liquids.
In fact Titan has its own water cycle much like Earth, but with liquid methane instead of water. Massive lakes of liquid methane feed methane clouds, which in turn rain massive raindrops on to the small, distant, moon.
