This perspective view of Marcia Crater on the giant asteroid Vesta shows the most spectacularly preserved example of "pitted terrain," an unexpected discovery in data returned by NASA's Dawn mission. ... Scientists think low-speed collisions with carbon-rich meteorites left hydrated minerals on Vesta's surface. Heat generated during later, high-speed collisions with asteroid belt rocks released water that was previously bound within the hydrated minerals. ...

The length of the shadow depends on the height of an object (like a mountain or a human) and how high up the Sun is. ... We can calculate the length of the shadow if we know the Sun's angle above the horizon and the object's height. ... The Earth spins 360 degrees in 24 hours, which means it spins 1 degree in 4 minutes; that in turn means the Sun moves 1 degree every 4 minutes in the sky. ...

For vi , a line is the string of characters between two <RETURN> characters. Although vi will automatically wrap the text onto a new line when it reaches the right-hand side of the screen, it does not insert a <RETURN> character. ... Adding a <RETURN> at the end of every line ensures that the appearance of the text on your screen corresponds to vi 's understanding of how text is structured. Setting the wrapmargin option automatically inserts a <RETURN> character whenever vi wraps text. ...
