An unusual population of the darkest, most lightweight galaxies known has shed new light on a cosmic conundrum. Astronomers used the W. M. Keck Observatory in Hawaii to show that the recently uncovered dwarf galaxies each contain 99 percent of a mysterious type of matter known as dark matter. Dark matter has gravitational effects on ordinary atoms but does not produce any light. It accounts for the majority of the mass in the universe.

A team of American and Canadian scientists has devised a new way to study Earth's past climate by analyzing the chemical composition of ancient marine fossils. The first published tests with the method further support the view that atmospheric CO2 has contributed to dramatic climate variations in the past, and strengthen projections that human CO2 emissions could cause global warming.

Astronomers from the California Institute of Technology and the University of Cambridge have developed a new camera that produces much more detailed pictures of stars and nebulae than even the Hubble Space Telescope, and it does all this from here on Earth.

An international team of astronomers has discovered the largest-radius and lowest-density exoplanet of all those whose mass and radius are known. It is a gas-giant planet about twice the size of Jupiter, and is likely to have a curved cometlike tail. It has been named TrES-4, to indicate that it is the fourth planet detected by the Trans-atlantic Exoplanet Survey (TrES) network of telescopes.

The stranglehold of nicotine addiction leads to more than four million smoking-related deaths each year. Scientists at the California Institute of Technology have now explained two roots of that addiction. The discoveries may offer new hope not just for smokers, but eventually also for sufferers of Parkinson's disease, a debilitating movement disorder that affects some 40 million people worldwide.

A team of European and American astronomers has announced the discovery of the best evidence yet for the nature of the star systems that explode as type Ia supernovae. The team obtained a unique set of observations with the European Southern Observatory's Very Large Telescope and the Keck I 10-meter telescope in Hawaii.

The exoplanet HD 189733b has just been found to have water vapor in its atmosphere. The observation provides the best evidence to date that water exists on worlds outside our own solar system.
