Market Mayhem! Worldwide Plunge

Last year, steep declines in Chinese stocks were periodically followed by dramatic, if less severe, declines in U.S. and European stocks.

On 2016’s first day of trading, it’s more of the same.

A little bit of soul

This image of the Soul Nebula (IC 1848) combines 21.1 hours of exposures through Hydrogen-alpha, Oxygen-III, and Sulfur-II filters. This object resides in the constellation Cassiopeia the Queen.

Jellyfish in the ocean of space

Supernova remnant IC 443 has the common name the Jellyfish Nebula, and it lies at the top right of this image. The other, larger, nebula is IC 444. Both objects are in the constellation Gemini the Twins. Terry Hancock from Grand Mesa, Colorado

Seven sisters

The Pleiades (M45) is the most famous star cluster in the sky. It lies 444 light-years away in the constellation Taurus the Bull. The clouds of gas seen in this image are not connected to the stars, but are a dust cloud through which the cluster is passing. Dave Doctor from Las Cruces, New Mexico

Old friend

The Orion Nebula (M42) may be the most photographed deep-sky object of all. It’s a huge emission nebula and star-forming complex. In addition to the glowing hydrogen, however, the object also has regions of both reflection and dark nebulae. James Esch from Lovettsville, Virginia

Boom goes the star

The Cygnus Loop is a huge supernova remnant some 2,500 light-years away. It has many components, and this image shows two of them well. At the top is the Witch’s Broom (NGC 6960), and Pickering’s Triangle (which doesn’t have its own designation) lies down and to the lower left of the Broom.
