The Solar Orbiter spacecraft, a joint mission between the European Space Agency and NASA, is the first to venture into a ...

The European Space Agency's Solar Orbiter captured the first-ever images of the sun's south pole in March, which were released this week.

Astronomers describe Mercury as an "inferior planet", because its orbital path around the sun is much closer than that of ...

Escaping the ecliptic plane takes some doing, by which I mean a lot of very expensive rocket fuel. The Solar Orbiter used Venus's gravity to help pull it out of the usual equatorial orbit around ...

We Earthlings see the sun every day of our lives—but gaining a truly new view of our star is a rare and precious thing. So ...

This is due to the ecliptic plane, the path along which the planets orbit the sun. What happens after February? The seven-planet alignment ends after Feb. 28 as Saturn moves out of view.
