Hot Topic Deep Space Cosmic Evolution
Star, Dwarf, Planet
Topic: Cosmic Evolution
Astronomers have discovered the coldest brown dwarf star ever observed. The finding is a step toward filling the gap between stars and planets.

Topic: Cosmic Evolution
The world's thinnest material has been used to study the 'fine structure constant', one of physic's universal constants. This number is important because it underlies reactions in stars that generate carbon - a molecule essential for life.

Finding More Organics in Space
Topic: Cosmic Evolution
Researchers have detected a molecule closely related to an amino acid at the center of our Milky Way Galaxy. The finding provides more evidence that precursor molecules important for the origin of life can be found in interstellar space.

The Oldest Asteroids
Topic: Cosmic Evolution
Scientists have discovered three asteroids that appear to be among the oldest objects in the Solar System. Studying these asteroids could yield important clues about the origin and evolution of the planets.

Grains of Sand Grow Into Planets
Topic: Cosmic Evolution
Astronomers have found small, sandy particles orbiting a newborn solar system at about the same distance as the Earth orbits the Sun. Their report could shed new light on how distant, Earth-like planets might form.

From Gas to Planets
Topic: Cosmic Evolution
Astronomers have discovered large amounts of organic gases and water vapor in a possible planet-forming region around a distant star. The findings provide a better view of early planet formation and could aid in the search for habitable extrasolar planets.

The 'Planet' in Planetary Nebulae
Topic: Cosmic Evolution
Scientists have found that planets may be partly responsible for the breathtaking appearance of planetary nebula. The research is helping astrobiologists understand the environments in which extrasolar planets develop, and providing insight into the future of our own Solar System.

Spitzer in the Sky, with Diamonds
Topic: Cosmic Evolution
Researchers have developed a strategy for finding diamonds in space that can be 25,000 times smaller than a grain of sand. These tiny particles could provide insight into the distribution of molecules in the Universe that are important for the origin of life.

Amino Acid Ingredients Found in Distant Galaxy
Topic: Cosmic Evolution
In the ultra-bright galaxy Arp 220, radio astronomers have for the first time detected all the ingredients of an amino acid beyond the Milky Way. The study confirms that familiar carbon chemistry exists in the distant universe, and could help constrain the search for life.

Flight of the Moth
Topic: Cosmic Evolution
A dusty disk that resembles the shape of a moth is providing new information about how planetary systems form and evolve.
