Mars holds two of humanity's greatest space ambitions, discovering alien life and establishing our first foothold on another world. Key to both is the discovery of water. We know it's at the poles, but where could we find it at lower latitudes? In a new paper, researchers carefully examined images of Mars taken by the Mars Reconnaissance Orbiter. They found examples of features, like "brain coral terrain", expanded craters, and ridges which are evidence of water ice just under the surface.

The Solar System lacks hot-jupiters, intensely hot gas giant planets, so close to their stars they take just days or even hours to orbit once. But there are some systems that have not one, but two hot-jupiters. In a new study, researchers show the long-term gravitational interactions with binary stars that can push multiple gas giants into these extremely close orbits around their stars. Both stars can end up with hot-jupiters.

The Earth's magnetosphere is a giant magnetic field that arises from the flow of material deep inside the planet. Because the flow of material isn't constant, the strength and shape of the magnetosphere can change over geologic time. But researchers have found that changes in the magnetosphere seem to be correlated with fluctuations in the amount of oxygen in the Earth's atmosphere. Both could be responding to a single underlying process.

NASA astronaut Bob Hines took this picture of the waning crescent moon on May 8, 2022, as the International Space Station flew into an orbital sunrise 260 miles above the Atlantic Ocean off the northwest coast of the United States.
