Neutron Stars: These remnants of supernova explosions are incredibly dense, with a teaspoon of neutron-star material weighing as much as a mountain.

How does your favorite planet spin? Does it spin rapidly around a nearly vertical axis, or horizontally, or backwards? The featured video animates NASA images of all eight planets in our Solar System to show them spinning side-by-side for an easy comparison. In the time-lapse video, a day on Earth -- one Earth rotation -- takes just a few seconds. Jupiter rotates the fastest, while Venus spins not only the slowest (can you see it?), but backwards. The inner rocky planets, across the top, most certainly underwent dramatic spin-altering collisions during the early days of the Solar System. The reasons why planets spin and tilt as they do remains a topic of research with much insight gained from modern computer modeling and the recent discovery and analysis of hundreds of exoplanets: planets orbiting other stars.

Nasa APIs

NASA APIs offer developers access to a wide range of space-related data, including astronomy, satellite imagery, and Mars exploration. These interfaces enable the creation of applications and visualizations, fostering innovation in space science and technology. Registration and the use of API keys are typically required for authentication and access to NASA's valuable data resources.
