NASA Scientists Find Evidence Of Water In Martian Meteorite
2014-02-28 07:16:06

Lawrence LeBlond for redOrbit.com - Your Universe Online Evidence of water and life on Mars is a hotly debated topic that has been ongoing for decades. While most scientists agree that Mars had an abundant source of water in its ancient past, there has only been limited evidence that life may have once existed on the Red Planet. However, scientists from NASA’ Johnson Space Center in Houston and the Jet Propulsion Laboratory in Pasadena, California have found evidence of past water...

Meteorite Linked To Martian Crust

Lee Rannals for redOrbit.com - Your Universe Online Researchers have identified a new class of Martian meteorite that they believe originated from Mars' crust. The team wrote in Thursday's issue of Science Express that this new meteorite contains more water than any other Martian meteorite ever found. The sample is the only one found that dates back to 2.1 billion years ago, which is an early era on Mars known as the Amazonian. The meteorite, known as Northwest Africa (NWA) 7034,...

Researchers at the California Institute of Technology (Caltech) have directly determined the surface temperature of early Mars for the first time, providing evidence that's consistent with a warmer and wetter Martian past. By analyzing carbonate minerals in a four-billion-year-old meteorite that originated near the surface of Mars, the scientists determined that the minerals formed at about 18 degrees Celsius (64 degrees Fahrenheit). "The thing that's really cool is that 18 degrees is not...

A new isotopic analysis of meteorites that have been in storage on Earth for quite some time points to a very reasonable scientific conclusion that Mars once had sea beds that were warm, wet and rich in organic chemicals. Dr. John Brandenburg, a former scientist at the Florida Space Institute-University of Central Florida, Kennedy Space Center, says that the meteorites he analyzed, come from rocks in the southern hemisphere of part of Mars.  The rocks are 4.5 Billion years old, the same...

By Kim McDonald, UC San Diego Chemists at UC San Diego have uncovered a new chemical reaction on tiny particulates in the atmosphere that could allow scientists to gain a glimpse from ancient rocks of what the atmospheres of the Earth and Mars were like hundreds of millions years ago. Their discovery also provides a simple chemical explanation for the unusual carbonate inclusions found in a meteorite from Mars that was once thought by some scientists to be evidence of ancient Martian life....

New information about Martian meteorites discovered by UH professor Through the study of a popular Martian meteorite's age, a University of Houston professor and his team have made significant discoveries about the timeline of volcanic activity on Mars. Thomas Lapen, assistant professor of geosciences at UH, describes his team's findings in a paper titled "A Younger Age for ALH84001 and its Geochemical Link to Shergottite Sources in Mars," appearing April 16 in Science, the world's leading...

Using more advanced analytical instruments now available, a Johnson Space Center research team has reexamined the 1996 finding that a meteorite contains strong evidence that life may have existed on ancient Mars. The new research focused on investigating alternate proposals for the creation of materials thought to be signs of ancient life found in the meteorite. The new study argues that ancient life remains the most plausible explanation for the materials and structures found in the...

Washington, DC -- Organic compounds contain carbon and hydrogen and form the building blocks of all life on Earth. By analyzing organic material and minerals in the Martian meteorite Allan Hills 84001, scientists at the Carnegie Institution's Geophysical Laboratory have shown for the first time that building blocks of life formed on Mars early in its history. Previously, scientists have thought that organic material in ALH 84001 was brought to Mars by meteorite impacts or more speculatively...

Panspermia -- Panspermia is a theory (more directly described as a hypothesis, as there is no compelling evidence yet available to support or contradict it) that suggests that the seeds of life are prevalent throughout the universe and life on Earth began by such seeds landing on Earth and propagating. The theory has origins in the ideas of Anaxagoras, a Greek philosopher. An important proponent of the theory was the British astronomer Sir Fred Hoyle. There is some evidence to...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
