Planetary scientists monitoring Mars through the newly arrived Mars Express orbiter are reporting the presence of methane in the martian atmosphere.

If true, either the planet is releasing methane trapped since its formation, perhaps through previously undetected volcanic eruptions or hot springs, or there is life on Mars.

Particle physicists have seen a rare happening that may force a rethink of current theories of sub-atomic matter.

After watching more than seven trillion disintegrations of the kaon particle they have seen three peculiar events when they expected to see just one.

Ability to fly at 7 times speed of sound could boost space flight.

Fifty-seven years after combat pilot Chuck Yeager broke the sound barrier, NASA will make a second attempt Saturday at flying an aircraft at 5,000 mph — about seven times Mach 1, the speed of sound.
