Passage 5

　　　 Meteorite (陨石) ALH840典型例题 studied by a research team led by scientists at NASA and Stanford University.

　　　 Using high-powered microscopes and other laboratory tests, the researchers found clues that they think were left by living things.

　　 One clue is a collection of flat, hard orange globe of carbon lining the insides of the cracks in the rock. These depos- its look like the carbon globules made by some kinds of bacteria (细菌). They might have been left by tiny life forms, or they might have been made by hot vapors carrying carbon dioxide.

　　 With these carbon globules is another piece of evidence, a group of chemicals called PAHS.　 These chemicals can be formed in space or when living things die and change into fossils (化石) So the PAHs in the meteorite might have come from ancient Martian life.

　　 Rings of tiny crystals around the carbon globules make up the third mineral clue. These crystals are made of iron and sul- phur (硫)joined together in compounds that are like chemicals in some of Earth's bacteria. But similar crystals can also be made by chemical reactions that can happen without life forms to carry them out.

　　 A fourth sign of life is a series of microscopic rounded shapes that look like fossils of bacteria. But to some scientists, these shapes may be too small to be the remains of living things.

The NASA team does not say these clues are proof of life on Mars. Any.of these clues might have been placed in the rock without the help of living creatures.　　　　

But they claim the idea of Martian life is the simplest way to explain them, They say it would take a lot of coincidences (巧合) to place all of these dues together in the Martian rock. These scientists have challenged others to help them search for more evidence to prove that their ideas are either right or wrong.

　　　 And research that might help answer this question is already 'under way.　 NASA has planned ten new missions to Mars over the next ten years and launched two of them last fall. They are called Mars Global Surveyor and Mars Pathfinder.

Several of the experiments on these spacecraft will search for clues to answer one of the greatest questions of our time. Are we alone in the universe?
