Solar Eclipse 20th March 2015 in case you are interested


A solar eclipse is set to block out nearly 90 per cent of sunlight across parts of Europe next month - and it will be the biggest event of its kind in 16 years.

On 20 March, the moon's orbit will see it travel in front of the sun, casting a shadow over Earth.

The eclipse will see up to 84 per cent of the sun covered in London - and around 94 per cent in Glasgow, Aberdeen and Edinburgh.

Meanwhile, electricity system operators have warned the eclipse poses a serious risk of blackouts all over Europe as the continent increasingly relies on solar power. *Eek!









In London, the partial eclipse - when the moon starts touching the sun's edge - will start at 8.45am GMT. The maximum eclipse will hit at 9.31am and this will be the point when the moon is closest to the centre of the sun.

By 10.41am the moon will leave the sun's edge and the partial eclipse will end




This animation is designed to appear from the 'point of view' of the eclipse as it will occur on March 20. It shows the shadow being cast over the UK, Greenland, Europe and into Russia


WHAT IS A TOTAL SOLAR ECLIPSE?



A total solar eclipse is only visible from a certain region on Earth and those who can see it are in the centre of the moon's shadow when it hits Earth. For a total eclipse to take place, the sun, moon and Earth must be in a direct line. The totality of the 11 August 1999 eclipse is shown

An eclipse occurs when one heavenly body, such as a moon or planet, moves into the shadow of another. On Earth there are two types - lunar eclipses and solar eclipses.

Lunar eclipse: For a lunar eclipse, the Earth moves between the sun and the moon and blocks sunlight normally reflected by the moon.

Instead of light hitting the moon’s surface, Earth's shadow falls on it and a lunar eclipse can only happen when the moon is full.

Solar eclipse: By comparison, a solar eclipse occurs when the orbit of the moon moves it between the sun and Earth.




A solar eclipse occurs when the orbit of the moon moves it between the sun and Earth. When this happens, the moon blocks the light of the sun

When this happens, the moon blocks the light of the sun reaching Earth and the moon casts a shadow on Earth.

Types of shadow: During a solar eclipse, the moon casts two shadows on Earth.

The first shadow is called the umbra, and this gets smaller as it reaches Earth.

The second shadow is known as the penumbra, and this gets larger as it reaches Earth.

There are additionally three types of solar eclipses:

Total: A total solar eclipse is only visible from a certain region on Earth and those who can see it are in the centre of the moon's shadow when it hits Earth.

For a total eclipse to take place, the sun, moon and Earth must be in a direct line.

People standing in the umbra will see a total eclipse and this will occur over the Faroe Islands on 20 March.

Partial solar eclipse: This occurs when the sun, moon and Earth don't line up exactly.

People standing in the penumbra will see a partial eclipse.

Annular: An annular eclipse happens when the moon is farthest from Earth. Because the moon is further from Earth, it appears smaller.

As a result, it doesn't block the entire view of the sun. The moon in front of the sun resembles a dark disk on top of a larger sun-colored disk and creates what looks like a ring around the moon.

Solar System




Filled with kinks, jets, strands and gores, Saturn's F ring has been sculpted by its two neighboring moons Prometheus (seen here) and Pandora. Even more amazing is the fact that the moons remain hard at work reshaping the ring even today.

Saturn and the red giant star Antares are forming a beautiful triangle with Mars. All three are brightly visible to the naked eye.





Haumea, a dwarf planet on the edge of our Solar system doesn't have the same kind of moons as its well-known cousin Pluto. Haumea has two known satellites, an unusually high spin rate and is also the “parent” of a large family of icy bodies in the outer Solar system that used to be chunks of its surface, but which now orbit the Sun on their own. These unique features are indicative of an ancient collision and make Haumea one of the most interesting objects in the Kuiper Belt.

Interesting theories:

Earth's atmosphere experienced the first significant, irreversible influx of oxygen as early as 2.33 billion years ago. This period marks the start of the Great Oxygenation Event, which was followed by further increases later in Earth's history. The rise of oxygen in Earth's atmosphere was an inevitable consequence of the formation of continents in the presence of life and plate tectonics.

I saw that there was an ISS timelapse thread but didn't see anything about the live stream. Feel free to merge if you don't think this should be in a separate thread.
