Hot Topic Deep Space Cosmic Evolution
 
Planets, Part Two
Topic: Cosmic Evolution
01/11/08
Astronomers have spotted a new class of star -- those that support the formation of a second generation of planets long after the stars themselves have formed. The finding is providing scientists with new information about the behavior of planet-forming stars.

Organic Dust Up
Topic: Cosmic Evolution
01/07/08
Astronomers have found complex organic molecules in a disk of red dust surrounding a distant star. The star is in the late stages of planet formation, suggesting that the basic building blocks of life may be common in planetary systems.

When Planets Were Born
Topic: Cosmic Evolution
01/04/08
Researchers have dated the earliest step of planet formation in our solar system. Understanding the processes of solar system formation can give us insight into Earth's history, and indicate how Earth-like planets may form elsewhere in the universe.

Solar System Flip Flop
Topic: Cosmic Evolution
12/20/07
Scientists have determined that the planets in our Solar System were not always in the same order. The findings could have implications in understanding how the planets and our Solar System formed, and ultimately how it became habitable for life as we know it.

Radio Astrobiology: Looking Beyond
Topic: Cosmic Evolution
12/17/07
In Astrobiology Magazine´s latest podcast, Pascale Ehrenfreund talks about newly discovered exoplanets, and explains what we still need to learn about the evolution of solar systems.

Miniature Worlds in the Making
Topic: Cosmic Evolution
11/23/07
Astronomers have found evidence for what might be the beginning of shrunken versions of our Solar System. They have shown that the birthplaces of planets exist not only around stars, but also around objects similar in size to Jupiter.

Pleiades Planets
Topic: Cosmic Evolution
11/18/07
Astronomers have found evidence that rocky terrestrial planets may be forming around the star HD 23514. This star is similar to our Sun, and is located in the Pleiades star cluster some 400 light years away.

Light of the Dragon
Topic: Cosmic Evolution
11/13/07
Astronomers have discovered a star more like our Sun than any other previously observed. The finding suggests that the Sun's chemical composition is not unique, as some previously thought, and could have implications in the search for habitable environments beyond our Solar System.

Here Comes the Sun
Topic: Cosmic Evolution
11/03/07
Scientists examining samples of the Solar Wind returned to Earth by NASA's Genesis mission are solving questions about how our Solar System evolved. This investigation is important in ultimately determining how the Solar System became habitable for life as we know it.

How Planets Grow Up
Topic: Cosmic Evolution
10/06/07
Astronomers have found three nearby stars that may hold 'embryonic planets' and could provide a missing link in planet-formation theories. Studying them could help flesh out concepts of how habitable planets form and where to look for them.
