For the first time ever, a tremor, similar to a small earthquake, has been recorded on Mars. This marsquake was detected by the Seismic Experiment for Interior Structure (SEIS) probe, carried to Mars with the InSight spacecraft. Researchers believe the event was caused by heating and cooling of the Martian surface, resulting in cracking of the crust on the Red Planet. This is the first discovery in the brand new science of Martian seismology.Read More First Marsquakes Ever Seen Shake up Science of the Red Planet
Animals will certainly join humans on our quest to colonize the planets and moons of our solar system. However, animals have not flown on space missions in quite a while, as space agencies are hesitant to bring them on involuntary journeys. The only cat to have ever flown in space, Félicette, is now being honored for her 1963 journey, with a new statue due to be erected in Paris.Read More In Space, No One Can Hear You Meow – A Sad Tale (Tail?) of the First Cat in Space
An asteroid orbiting backwards around the Sun may have come from another solar system, according to astronomers in France.
Asteroid 2015 BZ509 is roughly two miles across, and orbits the Sun at roughly the same distance as Jupiter. Computer simulations suggest the object may have joined our planetary family four-and-a-half billion years ago, just as the Earth and other planets were being formed.
