Renewable energy, from sources like solar and wind, is key to reducing reliance on fossil fuels, combating climate change, and improving health outcomes. With 49 nations already generating over half their elect
This coupling encompasses a variety of mechanisms and regions from turbulence and charge exchange in the solar wind to gravity waves and chemical/collisional interactions in planetary atmospheres. Space plasmas are often in a non-equilibrium state and they can be a highly nonlinear medium....
As a result, Earth’s surface has been continually changed and eroded into delicate systems of river valleys—a remarkable contrast to the surfaces of other planetary bodies where impact craters dominate. Few areas on Earth have been untouched by flowing water. As a result, river valleys are ...
The planetary climate is a measure of the long-term trends in the weather. Various factors are known to influence the climate, including ocean currents, surface albedo, greenhouse gases, variations in the solar luminosity, and changes to the planet's orbit. Based on historical records, the Eart...
A billion years ago, the moon stopped being geologically active [source: Lunar and Planetary Institute]. But that's not to say that the moon is doing nothing for us. Take a look at a few things that we would miss if our moon decamped to another neighborhood — or never moved to our...
Heliophysics missions study the sun and its influence on the solar system, including the effects of solar wind. According to NASA the goal of these missions is "to understand everything from how planetary atmospheres have formed, to how space weather can affect astronauts and technology near Ear...
NASAView is a Free Planetary Data System archive product display tool that runs on Sun/Solaries, Windows/NT/95, and PowerMac platforms with a common look-and-feel Graphical User Interface (GUI). Weak but quick and opens .qub files with ease. ...
The probability of winning is tiny. So in the game of planetary formation, forming a solar system with our Earth is like winning the lottery.获胜的可能性很小。所以在行星形成的游戏中，太阳系中诞生了地球就像中了彩票一样。Scientists are only now fitting together all the various chapters of this...
planet" [source:Howell]. But Kepler-78b might have a run for its money: KOI-1843.03 — a planet candidate — has an unconfirmed orbit of 4.25 hours, which could make it the fastest orbiting planet in the universe, if Kepler's laws of planetary motion hold true [source:Price and Rogers...
Space Exploration and Aerospace: Astrophysicists and aerospace engineers contribute to space exploration and satellite technology. Scientists at NASA conduct research on planetary science, astrophysics, and space missions, expanding our understanding of the universe. ...
