The Sun's influence extends well beyond the orbit of its planets, so we launched spacecraft like the Voyager 1 and 2 probes and NASA's various solar orbiters to study the Sun's effects on the rest of the solar system. Voyagers 1 and 2 are on a one-way trip, sent forth to study ...

Some spacecraft can be left to safely drift off into space as long as there is no chance of them hitting anything or causing any damage. That’s what happened to Spitzer, which will gently float away from the planet for the next 50 or so years as it orbits the sun and trails the Ea...

“My question is about the likelihood of intelligent life in billions of years. M-Class stars are extremely hostile to life (as we know it). Planets in the Goldilocks zone are so close that they are tidally locked like our Moon and always show one side toward the Sun. So one side is...
A comet's tail is its most defining characteristic. It can be long enough to span the distance between the Earth and the sun, and it always points away from the sun, no matter which direction the comet is traveling. That's because it's created by the solar wind, which is blowing gas...
In most cases, this barycenter is close enough the center of the Sun to make little difference. The Jupiter-Sun barycenter is actually just above the surface of the Sun. There is no real difference between Earth orbiting the Sun and Jupiter other than the size of the ...
Two or three times a year, the Full Moon phase coincides with the Moon reaching the lunar nodes of its orbit. These are the points where the Moon’s orbit crosses the ecliptic, which is the Sun’s path, seen from Earth. When this happens, Earth casts its shadow on the Full Moon, ca...
orbits of all the planets. How much lighter will the Sun be whenit completes the hydrogen burning phase? By how much will thischange the orbit of the Earth? Give your answers in numbers andin percent.我翻译一下:太阳通过核聚变将氢原子转变为氦原子,并释放能量。这一过程是太阳质量减少并因此...
Why the SpaceX Crew-9 launch has been delayed again London sparkles in astronaut’s gorgeous night shot from the ISS In his final weeks aboard the space station after six months in orbit, NASA astronaut Matthew Dominick has shared a gorgeous time-lapse of Earth. ...
