If you believe the movies, messages from outer space tend to be carried by UFOs or cute little aliens. But it turns out that secret dispatches from the stars are actually concealed in much less exciting envelopes. Scientists have long suspected that ancient messages lurk within meteorites which crash to earth. Now they have finally proved this theory.
Meteors that have crashed to Earth have long been regarded as relics of the early solar system. These craggy chunks of metal and rock are studded with chondrules — tiny, glassy, spherical grains that were once molten droplets. Scientists have thought that chondrules represent early kernels of terrestrial planets: As the solar system started to coalesce, these molten droplets collided with bits of gas and dust to form larger planetary precursors.
Thanks to NASA’s Mars Curiosity rover, we’re learning new things about the red planet nearly every day. However, we’re also learning a few new details about ancient Mars here on Earth, thanks to a meteorite from the planet discovered over 30 years ago.
According to new research from a team of scientists at MIT, Cambridge University, and other various institutions, the shape of the early solar system was likely determined a massively powerful magnetic fields, the likes of which has never been seen.
Sunny Sunday afternoons with clear azure blue skies, a promise of changing weather coming make me wonder whether we will see any of those Leonid meteors this week. If the clear skies prevail we can look forward to seeing some because the peak night is expected to be Monday, November 17 in the early evening-before bedtime!
Talk about heavy metal! This shiny, lumpy rock spotted by NASA’s Curiosity rover is likely made mostly of iron—and came from outer space! It’s an iron meteorite, similar to ones found in years past by Curiosity’s forerunners Spirit and Opportunity, but is considerably larger than any of the ones the MER rovers came across… in fact, at 2 meters (6.5 feet) wide this may very well be the biggest meteorite ever discovered on Mars
