DD Drop Down Panel lets you tuck away ordinary HTML content on the page and revealed on demand when the user clicks on the protruding tab. The rest of the page's content is pushed down when the hidden content is exposed. It comes with a handful of helpful features, from the use of an arrow image to reflect the current panel state, persistence of the panel state, option to automatically close the panel when a link or certain elements within it is clicked on, to the ability to customize the animation speed (or to disable it entirely).

The Milky Way Galaxy
The Milky Way Galaxy, as viewed from Earth, is situated on a spur off one of the spiral arms of the galaxy (see Sun's location and neighborhood),
and it appears as a hazy band of white light in the night sky arching across the entire celestial sphere. The light originates from stars and
other material that lie within the galactic plane. The plane of the Milky Way is inclined by about 60° to the ecliptic (the plane of the
Earth's orbit), with the North Galactic Pole situated at right ascension 12h 49m, declination +27.4° (B1950) near beta Comae Berenices.
The South Galactic Pole is near alpha Sculptoris.

A Barred Spiral Galaxy
The Milky Way is a barred spiral galaxy that is part of the Local Group of galaxies.
Although the Milky Way is one of billions of galaxies in the observable universe, its special significance to humanity is that
it is the home galaxy of our Solar System. The plane of the Milky Way galaxy is visible from Earth as a band of light in the
night sky, and it is the appearance of this band of light which has inspired the name for our galaxy. It is extremely difficult
to define the age at which the Milky Way formed, but the age of the oldest star in the Galaxy yet discovered, HE 1523-0901, is
estimated to be about 13.2 billion years, nearly as old as the Universe itself. -Source: Wikipedia.

Relative to the Celestial Equator
The Milky Way looks brightest in the direction of the constellation of Sagittarius, toward the galactic center. Relative to the celestial
equator, it passes as far north as the constellation of Cassiopeia and as far south as the constellation of Crux, indicating the high
inclination of Earth's equatorial plane and the plane of the ecliptic relative to the galactic plane. The fact that the Milky Way divides
the night sky into two roughly equal hemispheres indicates that the Solar System lies close to the galactic plane. The Milky Way has a
relatively low surface brightness, making it difficult to see from any urban or suburban location suffering from light pollution.
