A series of four studies have shed new light on the properties of the TRAPPIST-1 planetary system, currently our most optimal hope for evidence of biological life beyond the Solar system.
Changes in solar activity influence the colour and formation of clouds around the planet, researchers at Oxford and Reading universities found.
A study published in the journal Earth and Planetary Science Letters posits that Mars formed in what today is the Asteroid Belt, roughly one and a half times as far from the sun as its current position, before migrating to ...
Whether you're traveling across cities, continents or even oceans this holiday season, there is no long-haul flight quite like that of the Voyagers.
The temperature and pressure inside Jupiter range from about -100°C near the edge to about 15,000°C and 50m times the Earth's atmospheric pressure in the middle. Saturn, Uranus and Neptune are similar pressure cookers. As ...
The discovery of a planet with a highly elliptical orbit around an ancient star could help us understand more about how planetary systems form and evolve over time.
NASA's future planetary exploration efforts, including missions to Venus, require electronics capable of surviving temperatures of 470° C and above for long durations. Such durable electronics eliminate the need for cooling ...
Space may seem empty, but it's actually a dynamic place populated with near-invisible matter, and dominated by forces, in particular those created by magnetic fields. Magnetospheres—the magnetic fields around most planets—exist ...
We're all familiar with the idea of solar sails to explore the solar system, using the light pressure from the sun. But there's another propulsion system that could harness the power of the sun, electric sails, and it's a ...
Narrow dense rings of comets are coming together to form planets on the outskirts of at least three distant solar systems, astronomers have found in data from a pair of NASA telescopes.
