The Trojan asteroids that follow Mars in its orbit might have come from the planet itself, blown off in an ancient impact rather than being late arrivals, a new study suggests.
If such civilizations really existed in the past, could we find them today?
Data from an Indian lunar orbiter hints at substantial water in the lunar interior
One potential landing site appears to have ridges that hint at past hydrothermal activity
The super-sized successor to NASA’s legendary Hubble Space Telescope is more than a year away from deploying its massive two-storey tall, gold-plated mirrors in the harshness of deep space. That’s why scientists are busy freezing the US$9 billion, 6,200 kilogram spacecraft to see if they can break it here on Earth.
On Sunday July 23rd, a spectacular CME emerged from the farside of the sun.
The origin and nature of Mars is mysterious. It has geologically distinct hemispheres, with smooth lowlands in the north and cratered, high-elevation terrain in the south. The red planet also has two small oddly-shaped oblong moons and a composition that sets it apart from that of the Earth.
Scientists have discovered mystery signals coming from a star 11 light-years away. The “very peculiar” pulses appear to be unique to the red dwarf, scientists say, with observations of similar nearby stars showing no similar behavior.
Unchecked climate change would eventually lead to widespread devastation on Earth.
NASA’s Van Allen Probes have observed a new population of space sound waves, called plasmaspheric hiss, which are important in removing high-energy particles from around Earth that can damage satellites.
