In the early years of space flight, both Russians and Americans used pencils in space. Unfortunately, pencil lead is made of graphite, a highly conductive material. Snapped graphite leads and particles in zero gravity are hugely problematic, as they will get sucked into the air ventilation or electronic equipment, easily causing shorts or fires in the pure oxygen environment of a capsule.
After the fire in Apollo 1 which killed all the astronauts on board, NASA required a writing instrument that wasn’t a fire hazard. Fisher spent over a million dollars (of his own money) creating a pressurized ball point pen, which NASA bought at $2.95 each. The Russian space program also switched over from pencils shortly after.
40 years later snide morons on the internet still snigger about it, because snide morons on the internet never know what they are talking about.

Astronomers Get Rare Peek at Early Stage of Star Formation
ScienceDaily (Mar. 14, 2012) — Using radio and infrared telescopes, astronomers have obtained a first tantalizing look at a crucial early stage in star formation. The new observations promise to help scientists understand the early stages of a sequence of events through which a giant cloud of gas and dust collapses into dense cores that, in turn, form new stars.
The scientists studied a giant cloud about 770 light-years from Earth in the constellation Perseus. They used the European Space Agency’s Herschel Space Observatory and the National Science Foundation’s Green Bank Telescope (GBT) to make detailed observations of a clump, containing nearly 100 times the mass of the Sun, within that cloud.
”As long as there have been humans, we have searched for our place in the cosmos. Where are we, who are we? We find that we live on an insignificant planet of a humdrum star, lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people. We make our world significant by the courage of our questions, and by the depth of our answers.”
Distance: 3,000,000 (Million) Light-years away from Earth
The Triangulum Galaxy is a spiral galaxy in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598, and is sometimes informally referred to as the Pinwheel Galaxy, a nickname it shares with Messier 101. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, which includes the Milky Way Galaxy, the Andromeda Galaxy and about 30 other smaller galaxies. It is one of the most distant permanent objects that can be viewed with the naked eye.

Celestial Stunner: Venus to Cross Face of Sun This Year
On your 2012 calendar, be sure to put a big red circle around June 5. On that day, a celestial occurrence that will not be seen by human eyes until well into the 22nd century — the year 2117 to be exact — will take place.
The planet Venus will cross the face of the sun.
Through the balance of this winter season and well into the spring of 2012, Venus will gradually climb higher in the sky and grow progressively brighter, eventually becoming an “evening lantern” for those commuting home from work and school.
