Strange Flames on the International Space Station - June 21, 2013

Fire, it is often said, is mankind's oldest chemistry experiment.

For thousands of years, people have been mixing the oxygen-rich air of Earth with an almost endless variety of fuels to produce hot luminous flame.

Flames are hard to understand because they are complicated. In an ordinary candle flame, thousands of chemical reactions take place.

The familiar teardrop shape of the flame is an effect caused by gravity. Hot air rises and draws fresh cool air behind it. This is called buoyancy and is what makes the flame shoot up and flicker.

But what happens when you light a candle, say, on the International Space Station (ISS)?

In microgravity, flames burn differently—they form little spheres.

Recently, Williams and colleagues were doing an ISS experiment called "FLEX" to learn how to put out fires in microgravity when they came across something odd. Small droplets of heptane were burning inside the FLEX combustion chamber. As planned, the flames went out, but unexpectedly the droplets of fuel continued burning. They seemed to be burning without flames.

Ordinary, visible fire burns at a high temperature between 1500K and 2000K. Heptane flame balls on the ISS started out in this "hot fire" regime. But as the flame balls cooled and began to go out, a different kind of burning took over.

Cool flames burn at the relatively low temperature of 500K to 800K and their chemistry is completely different. Normal flames produce soot, CO2 and water. Cool flames produce carbon monoxide and formaldehyde.

It is possible that some unidentified flying orbs/spheres are related to ‘cool flame’ processes? sciencenasagov

Large Alien Spacecraft Near The ISS - Apr 7, 2013

A large unknown cylindrical shaped object became visible during the USSTREAM Live on April 7, 2013.

It is said that it is a reflection of the camera, but given the fact that in recent months many UFOs were observed near the ISS, it is virtually impossible that all of these observations are caused by a reflection of the camera, light reflections or cosmic rays.

Ball of light at ISS - NASA cut Live Stream - Mar 31, 2013

The first video shows a UFO / ball of light seen from the ISS on March 30, 2013.

The second video shows a similar UFO / ball of light caught on camera during the USSTREAM / Live ISS Stream one day later.

But NASA are about to cut the main feed again (second video) as this only appears on their NASA TV channel later as they have smaller parameters for screen size.

Incredible UFO Appears and Turns Near The ISS - Mar 24, 2013

An unknown object appears near the ISS during the live ISS feed, March 24, 2013.

We are witnessing an extraterrestrial or man made craft or it may be a reflection of the solar array?

It's remarkable; Over the past months, many UFOs and unknown objects are observed near the ISS.

Amazing Giant Cigar Shaped UFO Near The ISS, March 2013

Again a strange object near the ISS.

This time a giant unknown cigar shaped object, several times the size of the International Space Station, was recorded during the ISS Live Feed.

Fleet of UFOs at ISS - Febr 28, 2013

A fleet of UFOs captured on the ISS Live Stream on February 28, 2013.

UFOs like this are not uncommon passing by the ISS and NASA is full aware of the UFO presence around our planet!

NASA Admitting Existence of Orbs and Strange Moving Objects, 2013

For years, people have been clipping NASA footage from the space shuttle and the ISS that show strange lights and moving objects.

For Whitley Strieber's 1999 NBC special Confirmation, a NASA spokesman was asked to watch the famous STS-80 video, and said, while looking at some of the most amazing such footage ever made, "I don't see any evidence of UFOs here."

Now, NASA admits the truth: they don't know what these objects are, and have been observing them for years.

One has to ask, what about the footage that HASN'T been released to the public? Source: disclosetv
