What energizes the Heart Nebula?

A star cluster around 2 million years young surrounded by natal clouds of dust and glowing gas, M16 is also known as The Eagle Nebula.

How do violent stars affect their surroundings?

What's happening in and around the Cave Nebula?

Welcome to the December Solstice, the first day of winter in planet Earth's northern hemisphere and summer in the south.

What's happening in the sky? Unusual lights appeared last week to hover above Whitefish Bay on the eastern edge of Lake Superior between the USA and Canada.

From afar, the whole thing looks like an Eagle. A closer look at the Eagle Nebula, however, shows the bright region is actually a window into the center of a larger dark shell of dust.

Sundials use the location of a shadow to measure the Earth's rotation and indicate the time of day.

Sometimes even the dark dust of interstellar space has a serene beauty.
