3+ mon, 1+ week ago  (620+ words) Bit by bit, scientists are piecing together Mars' climate history. Thanks to orbiters armed with powerful cameras and rovers carrying suites of scientific instruments, the red planet's history is becoming clearer year-by-year. In the past decade or so, evidence of…...

1+ week, 16+ hour ago  (722+ words) The lunar south pole is where humanity plans to build its first permanent outpost but we still don't fully understand what lies beneath the surface. A new study has used radar to peer below the ground in one of the…...

1+ week, 2+ day ago  (221+ words) How does something come from nothing? It is perhaps the most profound question in all of science and one we still cannot fully answer. How did a barren, lifeless planet transform itself, over billions of years, into a world teeming…...

3+ week, 3+ day ago  (1060+ words) Asteroids don't get the love they deserve. They don't get "cool points" because they're not a planet or a potential life-harboring moon. They're "just a bunch of rocks". But asteroids are so much more, as they are time capsules of…...

4+ week, 1+ day ago  (172+ words) In the end, the researchers developed several hypotheses regarding the interior of 16 Psyche, which they note they will confirm once the Psyche spacecraft arrives at the asteroid. Better understanding 16 Psyche and its origins will not only enable scientists to gain…...

1+ mon, 3+ day ago  (654+ words) Earth was once a magma ocean world, just as all rocky worlds were early in their development, according to theory. As the very young Earth cooled, only the outer core remained molten, wrapped around a solid inner core and covered…...

1+ mon, 5+ day ago  (861+ words) One particularly well known fact about the Moon is that it doesn't have much of a magnetosphere to speak of. There's no blanket to protect it from the solar wind ravaging its surface, blowing away its atmosphere and charging the…...

1+ mon, 3+ week ago  (723+ words) Giant mpacts on Earth's surface can be cataclysmic events with far-reaching consequences. They can excavate massive craters like the Vredefort Crater. There's also growing evidence that impacts powerful enough can create a massive underground hydrothermal system of cracks and chemistry…...

1+ mon, 3+ week ago  (337+ words) NASA has announced the Space Umbrella project, in which participants will use data from NASA's Magnetosphere Multiscale (MMS) mission to shed light on solar storms. The Sun regularly emits streams of charged particles (solar wind) from its upper atmosphere (the…...
