No, the umbra is the darkest part, the area of maximum eclipse (which moves as the Earth turns).
The area of partial eclipse is called the penumbra.
Umbra and penumbra when referred to the moon describes the shadow which is formed when light is blocked from the sun, by the moon. This shadow which falls on the Earth and has two distinct regions; a partially shadowed area which is the penumbra and the centre point a totally dark umbra. We on Earth looking skyward and watching the shadow pass as the Earth revolves would describe the penumbra as a partial eclipse and the umbra as a total eclipse.
True. The umbra is the central darker total shadow of the Moon. Outside of this area, called the penumbra, is the lighter partial shadow. In this area, you would see a partial or annular eclipse. The umbra and penumbra are cone-shaped areas of full and partial shadow. The solar eclipse of January 14, 2010 (last week, as I write this) the Moon was so far away from the Earth that the umbra didn't reach all the way to the Earth. So the Sun was visible all the way around the Sun; and "annular", or ring-shaped eclipse.
partial lunar eclipse.
The narrow central region of the eclipse shadow, where the Sun's disc is totally obscured, is called the umbra. Areas that only observe a partial or incomplete eclipse are in the penumbra. Another term sometimes used for annular eclipses, where there is no umbra, is the antumbra, where only a small ring of light remains around the Moon.
Because the moon is small compared to the Earth, the shadow it casts isn't very large. The small size of the shadow and the rotation of the Earth mean that where you need to be to see a solar eclipse is very specific and changes from eclipse to eclipse. To see the next total solar eclipse, you'll have to travel to Northeastern Australia or North New Zealand on November 13, 2012. Good luck!
Not precisely. The umbra is the TOTAL part of the shadow. In a total eclipse, where the eclipsing object is spherical, then the "inner" part of the shadow is the umbra, but in a partial eclipse, there IS NO umbra; just the "penumbra", the partial shadow.
The umbra is the darker total shadow; the penumbra is the surrounding partial shadow.
You will see a partial eclipse if you are in the penumbra.
There are two parts of a shadow: the UMBRA and the PENUMBRA. UMBRA is the inner darker part of a shadow. PENUBMRA is the outher lighter layer of a shadow. During a solar eclipse, the area on the planet that witnesses a complete total solar eclipse would be under the moon's shadow's UMBRA. The area that views a partial solar eclipse would be under the PENUMBRAL shadow.
The darker complete shadow is the "umbra". The lighter partial shadow is the penumbra.
The umbraUmbra comes from the Latin "shadow". It is the darkest part of a shadow. From within the umbra, the source of light is completely blocked by the object causing the shadow. This contrasts with the penumbra, where the light source is only partially blocked and there is only a partial shadow.
Shadows have two parts, the umbra and the penumbra. The umbra is the darker part of the shadow, in which all of the light from the source is blocked by the object casting the shadow. The penumbra, also known as the half-shadow, is the grayish part along the edge of a shadow in which only some of the light from the source is blocked.During a solar eclipse, if you are within the umbra of the moon's shadow, you are witnessing a total eclipse, and if you are within the penumbra of the moon's shadow, you are witnessing a partial eclipse.
Those words refer to regions within a shadow. The 'umbra' is the region of total shadow, from within which none of the light source is visible. In the umbra of the moon's shadow, none of the sun is visible, and you're witnessing a 'total' solar eclipse. The penumbra is the area of partial shadow, from within which part but not all of the light source is visible. In the penumbra of the moon's shadow, part but not all of the sun is visible, and you're witnessing a 'partial' solar eclipse.
The umbra is associated with a total eclipse, penumbra with partial.
These areas are said to be in the umbra. From Britannica Online Encyclopedia (http://www.britannica.com/EBchecked/topic/613811/umbra): "in an eclipse of the Sun, the regions within the umbra experience a total eclipse and those within the penumbra, partial eclipse."
I think you are referring to the Moon's shadow, in which case this is the "Umbra" where the total eclipse is seen. While towards the edge a partial eclipse is seen under a "Penumbra".
