A way to grow plants in lunar soil Scientists have discovered a way to turn the moon’s soil into fertile ground for growing plants. Researchers used volcanic material to create simulated lunar regolith and treated the soil with bacteria to increase phosphorus availability, which allowed benth, a relative of tobacco, to grow with healthier stems […]

Jupiter-like planets push Earth-sized planets aside Jupiter-sized gas giant planets can cause chaos in young planetary systems, moving smaller planets out of their orbit and impacting the habitability of those planets. While Jupiter’s gravitational field acts as a shield for Earth, it would harm Earth’s climate if it were located in the middle of our […]

The cause of Mars’ strongest quake The strongest quake recorded on Mars, which lasted six hours but left no visible signs on the planet’s surface, was caused by tectonic activity rather than a colliding asteroid. While scientists believe Mars does not have plate tectonics like Earth, the quake was likely caused by the release of […]
