Chondrite Meteorite
Since Charles Darwin's day, theories about the birth of life have come and gone. Darwin famously speculated about life having begun in a warm pond. Researchers tested the idea in 2006 and found it wanting. They examined hot puddles in Kamchatka, Russia, and Mount Lassen in California and discovered that "hot acidic waters containing clay do not provide the right conditions for chemicals to assemble themselves into 'pioneer organisms'. "
Stanley Miller and Harold Urey conducted a famous experiment in 1953. While it has been used as a propaganda device for evolution, Jonathan Wells and other Darwin skeptics have pointed out its flaws. Wells said:
"The Miller-Urey experiment used a simulated atmosphere that geochemists now agree was incorrect, it was not the 'first successful attempt to show how organic molecules might have been produced on the early Earth.' When conditions are changed to reflect better knowledge of the Earth's early atmosphere, the experiment doesn't work."
Others have looked to outer space as a potential source of life. Sir Fred Hoyle, convinced that life could not have originated on earth, suggested that it was brought here from space. While this panspermia view has its advocates, the naturalistic answer to how life began on Earth remains as elusive as ever.
A new study by Yoshihiro Furukawa and others reported in Scientific American and originally published in Nature Geoscience speculates that life did not come from space but meteor impacts might have caused chemical reactions in the primordian ocean, jump starting life. In their simulation, they made chondrite (a common type of meteorite) strike the ocean, managing to produce some organic or carbon-based compounds, such as fatty acids and amines.
While Furukawa and colleagues made sure the results were not due to contamination, others remain skeptical about the significance of their find. Astrobiologist Jennifer Blank at the SETI Institute in Mountain View in California thinks we might never come up with a viable answer.
Indeed, the jump from amino acids to a functioning cell is nothing short of a miracle. Far from being a black box, the cell is an extremely complicated factory that needs to have all its components in place in order to function.
So where did life come from? Life could only come from life. The cell has an enormous amount of information programmed into it. It looks as if it has been designed.
Unfortunately, mentioning the word design is a sure way to get one expelled from academia.

What do you think about the magnetic properties of asteroids?
As you may know, a chondrite is a type of meteorite that contains minuscule ladybug sized pieces of glassy material. A Sky and Telescope article stated, "…certain meteorites, predominantly irons, stony-irons, and some ordinary chondrites, can be distinctly magnetized." In 1991, Galileo spacecraft flew past the asterod and it detected a magnetic field around the asteroid. This specific asteroid was Gaspra, and thought that this field is due to magnetized solid metal. Gaspra is too small to have a molten core, which is what gives the Earth its field. It is not known how Gaspra became magnetized. If one asteroid were magnetic, it would be assumed other asteroids are magnetic as well.
What do you think about the magnetic properties of most asteroids? Are these just isolated cases, or do you feel that is common amongst most asteroids?
Good question-Habs is an abbreviation of "les habitants," the informal name given to the original settlers of New France, dating back to the 17th Century. So it's a natural fit for the The Montreal Canadiens, established in 1909 and marketed as a French-Canadian hockey team.
Having said that, the nickname might have been the result of an error. According to NHL.com, the first man to refer to the team as "the Habs" was Tex Rickard, owner of Madison Square Garden, in 1924. Rickard apparently told a reporter that the "H" on the Canadiens' sweaters was for "Habitants." Not true. The distinctive C-wrapped-around-H logo stands for "Club de Hockey Canadien."
You can tell I was the MAN in science.At what time will the biology question be asked?Cause I have an answer about 2 girls with a cup experiment.

We’re not alone, says Richard Hoover, a Nasa astrobiologist who claims to have discovered fossilised evidence of alien bacteria in an extremely rare form of meteorite.
Hoover cracked open a variety of carbonaceous chondrite meteorites, including new fragments from the French Orguiel meteorite of 1864, and examined the freshly-broken surfaces to look for fossilised remains. He found "large complex filaments", which he believes are fossilised alien life that resembles earthly cyanobacteria.
