... Special Reports Giant space cloud may be powered by black holes 17:57 23 April 2007 NewScientist.com news service David Shiga An enormous cloud of roiling plasma in space may be drawing its energy from black holes, new observations suggest. Such clouds might be sources for the mysterious particles that occasionally crash into Earth's atmosphere at ultra - high speed. ... But higher energy particles in the cloud may be able to escape, he says. ...

. This image shows a dark cloud where new stars are forming along with a cluster of brilliant stars that have already emerged from their dusty stellar nursery. This cloud is known as Lupus 3, and it lies about 600 light-years from Earth in the constellation of Scorpius the Scorpion. It is likely that the Sun formed in a similar star formation region more than 4 billion years ago. // Credit: ESO/F. Comeron

... Views of Martian Clouds . ... Although not as pronounced as on Earth , clouds are common features on Mars.
