The findings from the Curiosity rover could help the Perseverance rover decide which samples to collect for later analysis.
Methane tends to only be made by biological life, so scientists are wondering if the source is from alien microbes.
Although the asteroid, Bennu, only has a 1-in-2700 chance of hitting Earth, scientists are taking the risk seriously.
Scientists are concerned that increasing amounts of meltwater could be finding its way into the ocean.
The researchers created a computer model to predict the ways the planets would scatter, finding that slight tweaks to starting positions lead to vastly different outcomes
Physicists analyzed data from the first ever gravitational waves detected to prove Hawking's theory, and think that even more could be discovered from studying the ripples in space-time.
The researchers say that they want to use the survey to better understand our own place in the universe.
Astrophysicists are using the simulation to learn how stars form, how they arrange themselves into galaxies, and how the heavy elements that are vital to complex life are forged.
The researchers found the result by studying a tiny, jiggling membrane. Their experiment could lay the groundwork for further tests of the laws of thermodynamics at the tiniest scales.
Researchers say the new network will be unhackable and able to coordinate systems to unprecedented levels. Many of the deeper implications, however, cannot be foreseen.
The increasing number of satellites and space debris orbiting Earth could prevent astronomers from making crucial discoveries.
Astrophysicists think a newly discovered region of the Milky Way could provide hints about the evolution of our galaxy and its potentially violent past.
The scientists trapped the antimatter in a magnetic field to stop it from annihilating, before blasting it with a cooling laser.
Scientists may have finally made a complete digital model for the Cosmos panel of a 2,000-year-old mechanical device called the Antikythera mechanism that's believed to be the world's first computer.
A supermassive black hole is racing across the universe at 110,000 mph (177,000 km/h), and the astronomers who spotted it don't know why.
The experiment could be a trial for many more even smaller ones probing the long-kept secrets of quantum scale gravity.
