Hot Topic Deep Space Cosmic Evolution
New Technique to Weigh Planets
Topic: Cosmic Evolution
For the first time, scientists have developed a method for determining the mass of non-transiting exoplanets. The research could even lead to techniques for detecting molecules associated with the presence of life on such worlds.

Star Cluster Could Help in the Search for Earths
Topic: Cosmic Evolution
A unique group of stars could provide important information about the evolution of sun-like stars and aid in the search for Earth-like worlds. The loose cluster of stars, known as NGC 6774, contains many that are similar to the Sun in both mass and age.

Earth-like Planets Just as Likely to Form Around Low-Metal Stars
Topic: Cosmic Evolution
A new study based on data from the Kepler mission indicates that planets as big as Earth but smaller than Neptune could be more common in our galaxy than previously believed.

Planets Can Form Around Different Types of Stars
Topic: Cosmic Evolution
New research shows that small planets could form around stars that are poor in heavy elements. The study may significantly increase the likelihood that Earth-like planets are widespread in the Universe.

Few Brown Dwarfs Close to Home
Topic: Cosmic Evolution
Data from the WISE survey has turned up a new crowd of stars close to our own position in the Milky Way. However, the results show that there are fewer brown dwarfs nearby than expected.

Stellar Archaeology Traces Milky Way's History
Topic: Cosmic Evolution
A new study has revealed that white dwarfs in the inner region of the Milky Way galaxy's halo are younger than the first generation of Milky Way stars.

More Star Stuff Than We Thought
Topic: Cosmic Evolution
A new study shows that there is more hydrogen gas in the Universe than previously thought.

Ghostly Gamma Rays of the Galaxy
Topic: Cosmic Evolution
Compared to other galaxies, the Milky Way has a relatively quiet core. New research, however, shows that our galaxy was not always so peaceful.

Nomads of the Galaxy
Topic: Cosmic Evolution
A new study has estimated the number of 'nomad planets' that might exist in the Milky Way Galaxy: 100,000 for every star. The Milky Way contains 200 to 400 billion stars, meanining quadrillions of nomad planets could be drifting through the space between the stars of our galaxy.

The Older We Get, the Less We Know (Cosmologically)
Topic: Cosmic Evolution
A new study is helping scientists better understand the 13.7-billion-year history of the Universe.
