Answer:

Quoting Dibyo

ALH 84001 was found in Antarctica during the 1984-1985 Antarctic summer. It was found by a team of meteorite hunters from the ANSMET program, which is sponsored by the Polar Programs Office of the U.S. National Science Foundation

The rock has crystalline lines which scientists thought were mineral deposits that replaced bacteria. This assumption was far fetched. The lines are simply strings of crystals that normally form on Earth in a magnetic field

    1. ALH84001 – martian meteorite found in Antarctica.

    2. Electron microscopic image of the fragment of the meteorite. It revealed bacteria like lifeforms. But the debate is still going on whether the bacteria is really martian or is because of contamination on Earth.


  3. 1. ALH84001 – meteorite supposed to have originated on mars.
    2. believed to be the fossilized remains of nanobacteria. If true, then we have a contact!

    1. Allan Hills 84001. ALH 84001 is thought to be from Mars, is a meteorite that was found in Allan Hills, Antarctica.
    2. Under the scanning electron microscope, the worm like structures were revealed to be the remains of the form of fossils of bacteria-like lifeforms. This provides the most compelling evidences of Bacterial life existing on Mars. The so called bio-morphs are embedded beneath the surface layers of the rock, suggesting that they were already present when the meteorite arrived, rather than being the result of subsequent contamination by Earthly bacteria.

    The ALH84001 meteorite, thought to be from Mars, was found on December 1984 on Antarctica.
    An electron microscope reveals bacteria-like structures in the meteorite fragment. Proving the existence of Life on Mars once upon a time.

    Meteorite fragment ALH 84001 found in Antarctica has chain structures.Possibly indicating life.

    ALH84001,

    On August 6, 1996[4] ALH 84001 became newsworthy when it was announced that the meteorite may contain evidence for traces of life from Mars, as published in an article in Science by David McKay of NASA.[5]

    The electron microscope revealed chain structures in meteorite fragment ALH84001
    Under the scanning electron microscope structures were revealed that may be the remains—in the form of fossils—of bacteria-like lifeforms. The structures found on ALH 84001 are 20-100 nanometres in diameter, similar in size to the theoretical nanobacteria, but smaller than any known cellular life at the time of their discovery. If the structures are really fossilized lifeforms, they would be the first solid evidence of the existence of extraterrestrial life, aside from the chance of their origin being terrestrial contamination.[6]

    (1) is the Mars meteorite fragment found in Antarctica in the 80s. When it was examined under an electron microscope fossilised life-forms like (2) akin to bacteria were observed and this started off a frenzy about the possibility of life on Mars.

    ALH84001, Mars meteorite recovered from Antarctica, containing what were believed to be fossilized microorganisms.

    Allan Hills (ALH) 84001.
    Came into news due to structures (the ‘bacillus’ in image 2) that were believed to be fossilized bacteria.

    ALH84001, the “life on Mars” meteorite, which may contain up to 25% fossilized Martian bacteria.
    Per Wikipedia:
    Some structures resembling the mineralized casts of terrestrial bacteria and their appendages (fibrils) or by-products (extracellular polymeric substances) occur in the rims of carbonate globules and preterrestrial aqueous alteration regions. The size and shape of the objects is consistent with Earthly fossilized nanobacteria, but the existence of nanobacteria itself is controversial.

    1. Allan Hills 84001 – a lump of meteorite found in Antarctica

    2. An electron microscope visual of the ALH84001 showing chain-like bacteria-type ‘life forms’ – nanobacteria.


  18. Rithwik K

    1 – Allan Hills 84001

    The electron microscope revealed chain structures in meteorite fragment ALH84001


  19. xtremevarun

    ALH84001 ;polycyclic aromatic hydrocarbons (PAHs) are formed when bacteria die,the ones in this one do not resemble anything ‘earthly’


  20. Ps

    Allan Hills 84001 or ALH 84001, the metorite in antarctica that raised the entire life on mars (2) debate, with the possibility of fosilised bacteria.

    Meh! Always knew the little green chaps were watching us
