The galaxy cluster 1E 0657-56 (known as the Bullet Cluster) lies 3.8 billion light-years away. It's one of hundreds that appear to be carried along by a mysterious cosmic flow. NASA/STScI/Magellan/U.Arizona/D.Clowe et al.
This artist's conception illustrates one of the most primitive supermassive black holes known (central black dot) at the core of a young, star-rich galaxy. Astronomers using NASA's Spitzer Space Telescope have uncovered two of these early objects, dating back to about 13 billion years ago. The monstrous black holes are among the most distant known, and appear to be in the very earliest stages of formation, earlier than any observed so far. Unlike all other supermassive black holes probed to date, this primitive duo, called J0005-0006 and J0303-0019, lacks dust. As the drawing shows, gas swirls around a black hole in what is called an accretion disk. Usually, the accretion disk is surrounded by a dark doughnut-like dusty structure called a dust torus. But for the primitive black holes, the dust tori are missing and only gas disks are observed. This is because the early universe was clean as a whistle. Enough time had not passed for molecules to clump together into dust particles. Some black holes forming in this era thus started out lacking dust. As they grew, gobbling up more and more mass, they are thought to have accumulated dusty rings. This illustration also shows how supermassive black holes can distort space and light around them (see warped stars behind black hole). Stars from the galaxy can be seen sprinkled throughout, and distant mergers between other galaxies are illustrated in the background. (Credit: NASA/JPL-Caltech)
A prescribed burn was conducted in July 2001 in the Giant Forest of Sequoia National Park. The giant redwoods endured frequent fires from the yeas 800 to 1300. Human activity reduced fires in recent decades but now scientists have reintroduced fire to the ecosystem. Credit: Tony C. Caprio
