Hot Topic Deep Space Cosmic Evolution
 
Tidal Locking Could Render Habitable Planets Inhospitable
Topic: Cosmic Evolution
12/08/11
Planets that are tidally locked, with the same side always facing their sun, could end up with climates that spiral out of control.

Heavy Metal Stars Produce Earth-Like Planets
Topic: Cosmic Evolution
09/29/11
Examining the wealth of data from Kepler, astronomers have seen a positive correlation between stellar composition and planetary formation, a correlation that could affect how we search for life in the universe.

How to Keep Lonely Exoplanets Snug – Just Add Dark Matter!
Topic: Cosmic Evolution
06/23/11
Dark matter, inferred to exist from its gravitational effects on the universe, is still a mystery to scientists. But a new study says that dark matter could help life evolve and survive on distant worlds outside of our solar system.

Supernova´s Spin on Life
Topic: Cosmic Evolution
08/12/10
A bias in the way amino acids twist could be due to supernovae, researchers now suggest. If correct, this could be more evidence that the molecules of life came from elsewhere in the cosmos.

Recipes for Renegade Planets
Topic: Cosmic Evolution
07/08/10
Recent discoveries of gas giant planets in unusual orbits challenge the generally accepted theory of planet formation. While these discoveries do not disprove the theory, they have opened our eyes to chaotic solar systems quite unlike our own.

Getting WISE About Nemesis
Topic: Cosmic Evolution
03/11/10
Is our Sun part of a binary star system? An unseen companion star, nicknamed "Nemesis," may be sending comets towards Earth. If Nemesis exists, NASA´s new WISE telescope should be able to spot it.

A Drop in the Bucket
Topic: Cosmic Evolution
02/18/10
A new technique is being developed to detect water in the protoplanetary disks of other solar systems. If successful, it would help in our understanding of how habitable planets form.

Solar System Shield
Topic: Cosmic Evolution
01/14/10
Water vapor in planet-forming disks may block ultraviolet radiation from destroying water and other important molecules for life, according to new calculations.

Superior Super Earths
Topic: Cosmic Evolution
11/30/09
Super Earths are named for their size, but these planets – which range from about 2 to 10 Earth masses – could be superior to the Earth when it comes to sustaining life. They could also provide an answer to the ‘Fermi Paradox´: Why haven´t we been visited by aliens?

Detecting Life-Friendly Moons
Topic: Cosmic Evolution
10/26/09
The search for life-friendly real estate around distant stars doesn't have to be limited to planets. New research shows that habitable exomoons can be detected with a new method using current technology.
