A rare hybrid solar eclipse has been captured on film after appearing in the skies above Africa, the US and Canada.
The total solar eclipse was the final eclipse event of 2013 and the "most interesting" of the year, Nasa said.
The space agency said the eclipse is rare because some sections of the path are annular, or ring-shaped, while other parts involve a total eclipse. There will not be another eclipse of this type for another 10 years.
"The duality comes about when the vertex of the Moon's umbral shadow pierces Earth's surface at some locations, but falls short of the planet along other sections of the path," Nasa said.
"In most cases, the central path begins annular, changes to total for the middle portion of the track, and reverts back to annular towards the end of the path.
"However, [the] November 3 eclipse is even more unique because the central path begins annular and ends total. Because hybrid eclipses occur near the vertex of the Moon's umbral/antumbral shadows, the central path is typically quite narrow."
The hybrid eclipse began in the North Atlantic, east of Jacksonville in Florida, and moved eastwards to Africa, arriving at Cape Verde first.
After moving across Gabon, the Democratic Republic of the Congo and Kenya, the eclipse ended its journey in Ethiopia.
Paul Cox, who hosted a live webcast of the solar eclipse from Kenya, told space.com: "We witnessed totality here, and it was stunning."
