Hot Topic Deep Space Cosmic Evolution
 
Alien Astronomy, a Trillion Years from Now
Topic: Cosmic Evolution
04/17/11
Summary: In a trillion years, astronomers in our galaxy will have a difficult time figuring out how the Universe began. The evidence we have today in support of the Big Bang will no longer be available.

WISE Delivers Millions of Galaxies, Stars and Asteroids
Topic: Cosmic Evolution
04/16/11
Summary: Astronomers across the globe can now sift through hundreds of millions of galaxies, stars and asteroids collected in the first bundle of data from NASA´s Wide-field Infrared Survey Explorer (WISE) mission. The data is invaluable for astrobiologists seeking to understand the nature of our universe and the potential for habitable planets other than our own Earth.

Star Formation Linked to Sonic Booms
Topic: Cosmic Evolution
04/16/11
Summary: New observations reveal that nearby interstellar clouds contain networks of gaseous filaments that may result from interstellar sonic booms.

Colliding Black Holes Warp Space and Time
Topic: Cosmic Evolution
04/13/11
Summary: Physicists have gained new insight into the warping of space and time that occurs when black holes collide.

Kepler's Census of Sun-Like Stars
Topic: Cosmic Evolution
04/13/11
Summary: NASA's Kepler mission has spotted 500 Sun-like stars that show changes in brightness. The data is helping astronomers understand the mass, radius, age and internal structure of stars. The information will ultimately help astrobiologists search for habitable planets beyond our solar system.

Two Dying Stars Reborn as One
Topic: Cosmic Evolution
04/11/11
Summary: Astronomers have discovered a pair of white dwarf stars that orbit each other at a distance less that that from the Earth to the Moon. It is believed that in a few million years, the stars will collide to be 'reborn' as a single star.

Unwrapping the Ribbon of Energy around our Solar System
Topic: Cosmic Evolution
04/03/11
Summary: Data from NASA's IBEX mission has overturned 40 years of theory by isolating a mysterious 'ribbon' of energy and particles found in the heliosphere. Studying the heliosphere is important because its influence it thought to help protect our solar system, and life on Earth, from galactic cosmic rays.

The Strong Force
Topic: Cosmic Evolution
04/01/11
Summary: New research is helping scientists understand one of the four fundamental forces of the Universe.

The Big Rock Candy Solar System
Topic: Cosmic Evolution
03/29/11
Summary: A new study shows that the earliest rocks in our solar system were more like cotton candy than the hard rocks we're familiar with today. The research is providing a better picture of how rocky planets form and could help in the search for habitable worlds around distant stars.

The Borderline Between Star and Planet
Topic: Cosmic Evolution
03/23/11
Summary: Astronomers have discovered the coldest known star. The unique brown dwarf has properties that are different from any other star and, in some ways, make it more similar to a cold, giant exoplanet.
