MARS

The rivers on Titan, Saturn’s biggest moon, flow across its landscape the way they used to on Mars before it dried up, so Titan may not be as similar to Earth as we thought.

The dwarf planet Ceres was in the perfect spot for NASA’s Dawn spacecraft to take shots of its bright surface and its even brighter crater.

A human space colony on Mars or another planet may evolve into a different race if we leave inhabitants alone to breed.

The atmosphere on Mars evolved over time, and during that period of climate change, rain probably fell hard enough in storms that carved out the surface and eroded craters.

Three billion years ago, Mars had conditions similar to those on Earth.

Earth isn’t the only planet in our solar systems that has storms. Clouds gather and lightning crashes throughout our neighborhood.

A team of researchers used a combination of laboratory impact experiments, computer models and geological observations to explain the formation of bright streaks around some impact craters on Mars.

China has eight students living in a space colony simulation called the “lunar palace” to help prep the country for sending astronauts to the moon and to Mars.

When astronauts are on the International Space Station, their blood doesn’t transport as much oxygen to their muscles and they grow weaker.

When science and art come together, it can help us envision what our universe looks like beyond the bonds of Earth’s gravity.

The image, snapped using the orbiter's HiRise camera, shows several RSLs that appear as dark lines extending downslope.

The Mars rover Curiosity is carrying dirt in its hand as it scales a mountain and continues exploring another planet.

Stephen Hawking says humans have to leave Earth in the next 100 years and colonize another planet if we want any hope of surviving extinction.

Elon Musk is changing the world for humanity. Albert Einstein redefined the universe for humanity.

The image, taken using the orbiter's HiRise camera, shows sedimentary rock layers covered in wind-blown sand.

The dust on Mars may be a good basis for creating "bricks" for building on the planet.

During the early years of the solar system, Mars got a little break from constant bombardment by space objects before the asteroids started up again.

The entrepreneur starts off by defining a goal and understanding what that goal is and why it is a good and valid goal.

When we finally find aliens living on an Earth-like planet outside our solar system, it might be swimming — because habitable exoplanets are probably completely covered in ocean.

The rover, which has been on Mars since 2004, is leaving the “Cape Tribulation” and is moving toward “Perseverance Valley,” both part of the western rim of Endeavour Crater.

A new planet scientists found orbiting a small star is being called a “super-Jupiter” because it’s almost three times bigger than the largest planet in our solar system.
