Hot Topic Deep Space New Planets
 
Tiny Planet SIM
Topic: New Planets
08/01/03
The challenges of observing a tiny planet against the vast star background and the brightness of a parent sun has not discouraged planet finders. In the coming years, six new space-borne missions are slated for a closer look at the problem.

Planets Need Heavy-Metal
Topic: New Planets
07/26/03
Astronomers have previously estimated that around five percent of stars may have planets, but a survey by Berkeley planet finders has refined this classification. If a star is rich in metals, particularly iron and other heavy metals, then it stands a remarkable one-in-five chance of also hosting planets.

Interview with Neville Woolf: Part II
Topic: New Planets
07/23/03
This is the second of a two-part interview with Neville Woolf, a Professor of Astronomy at the University of Arizona. Woolf is the principal investigator of one of the lead teams recently awarded a five-year grant by the NASA Astrobiology Institute (NAI) to conduct astrobiology-related research.

Ancient Planet Discovered
Topic: New Planets
07/14/03
Using the Hubble Space Telescope, astronomers have identified the oldest and most distant known planet orbiting two burned-out stars. Its sky location in the constellation Scorpius places the planet as the M4 globular cluster. The discovered world is also the only planet found to orbit around a binary star system.

Rock, Scissors, Paper and Water
Topic: New Planets
07/13/03
A recent European conference discussed what a new class of planetary search candidates called 'waterworlds' might require: foremost after water itself, for life to originate elsewhere on a distant world depends on a rocky core and organic pulp.

Similar Solar System at 90 Light Years
Topic: New Planets
07/07/03
Astronomers have found the first sun-like star with a giant gas planet in an orbit similar to Jupiter's. At a distance of 90 light-years, the similar solar system to ours means that this gas giant could attract most of the dangerous impact debris.

Twins Combine Planetary Light
Topic: New Planets
07/05/03
Debuting the first discoveries from the world's largest optical telescope, researchers have used the Keck Interferometer to combine light from two telescopes. Astronomers can see the growing gap between a star and its planets as they begin to accrete.

Inference and Red Corn
Topic: New Planets
06/24/03
Mathematical astronomer, Simon Newcomb, describes the limits of life on Earth and endeavors to ask the right questions about what might be required to discover life elsewhere.

Celestial Birthing Grounds: Wild Places
Topic: New Planets
05/26/03
A University of Florida sky survey has doubled the number of planet forming disks in a cluster of young stars, and suggests that planets may pop up within the first 3 million years of a star's life.
