Astrobiologist Dirk Schulze-Makuch believes that humans may have unintentionally killed life on Mars in the 1970s.
Nasa has announced the first detection of possible biosignatures in a rock on the surface of Mars.
A team of researchers has uncovered evidence of its origins in the atmosphere, where carbon dioxide bathed in ultraviolet sunlight reacted to form a mist of carbon molecules that rained onto the planet's surface.
The mystery of life’s origins on Earth has long puzzled scientists, but a recent discovery on Mars might be shedding new light on this profound question, while also inching closer to finding life on Mars.
If life ever existed on Mars, the Perseverance rover’s verification of lake sediments at the base of the Jezero crater reinforces the hope that traces might be found in the crater.
Researchers poring over imagery and data from the Perseverance rover on Mars have found evidence of organic molecules in the planet’s Jezero Crater, potentially providing evidence of the planet’s carbon cycles and its ability to host life.
A Martian meteorite that crashed in Morocco 11 years ago contains a vast diversity of organic compounds, which could help researchers discover if Mars could have hosted life and provide important clues about Earth's geological history.
A recent study finds that the vast subsurface fracture networks in Gale crater would have provided water-rich and radiation-shielded conditions that were potentially more habitable than those on the surface.
NASA scientists said Thursday the Mars Perseverance rover found biologically-interesting rocks in an ancient lake bed that could indicate microbial life existed on the red planet billions of years ago.
Some scientists think the best place to find evidence of life is one of Mars’ moons. They might serve as a depository for material that was blasted off of Mars’ surface in the past.
When light shines on biological matter, part of the wavelength of the light that is reflected back is curled in either a clockwise or counterclockwise spiral. Astrobiologists used this phenomena in their remote sensing technique.
4 billion year old Nitrogen containing organic molecules has been discovered in Martian meteorites. This finding suggests a wet and organic-rich early Mars, which could have been habitable and favorable for life to start.
The molecules were extracted by the Curiosity rover from a mudstone section of the Gale Crater. Scientists have concluded that we can't rule out those molecules actually have a biological origin.
NASA's Curiosity rover discovered "startlingly high amounts of methane in the Martian air" on Wednesday in what could potentially be a sign of life on the Red Planet, the New York Times reported on Saturday.
