Hot Topic Deep Space New Planets
 
Get in Line to Find Extrasolar Planet
Topic: New Planets
07/09/04
The largest continental telescope also sees in the darkest sky. Using a novel method to queue its best exposures on a schedule with the full moon, the West Texas observatory has identified its first extrasolar planet around a star comparable in composition to our own Sun.

Young Planet Challenges Old Theories
Topic: New Planets
05/28/04
The Spitzer Space Telescope has detected youngest planet ever found, claim NASA scientists. Planets are thought to take millions of years to form after a star is born, but discovery of a million-year old star with planet already in orbit around it means scientists may have to rethink planetary formation models.

Two New Very Hot Jupiters
Topic: New Planets
05/11/04
The transit method of new planet discovery relies on observing distant eclipses. Faint starlight decreases once during each orbit as the inferred planet passes between Earth and the star. The second and third new planets discovered using this technique are reported to be large, inner planets, or so-called "hot Jupiters".

Nearby Planet Nursery
Topic: New Planets
04/24/04
In an exclusive interview with Berkeley astronomer, Paul Kalas, he describes how their planet-finding team uncovered a nearby nursery that may include the closest star with an embryonic solar system in the making.

New Planet, Magnified
Topic: New Planets
04/16/04
The gravity of a star can act as a lens, focusing and intensifying the light of a star behind it. The combined light from the two stars causes that point in the night sky to suddenly appear much brighter. For the first time, a planet has been discovered using this "gravitational microlensing." technique.

How Many Earths?
Topic: New Planets
04/01/04
About half of hundred solar systems with known planets may hold potential Earths. Simulating whether such stars and outer planets might eject an Earth-like world, the results also suggest another possibility, a habitable moon around a much larger Jupiter-like world.

Nearest Young Planet-forming Star Found
Topic: New Planets
02/26/04
The nearest, youngest star with dusty debris disk - the stuff from which planets form - has been found by Berkeley and Hawaii astronomers a mere 33 light-years away.

A Good Planet Is Hard To Find?
Topic: New Planets
02/21/04
Harvard-Smithsonian astronomers have simulated the early planet formation around stars like our own. It turns out that an alien astronomer could have seen the embryonic Earth in its earliest dusty stages.

Dying Planet Leaks Carbon-Oxygen
Topic: New Planets
02/02/04
Using the Hubble Space Telescope to view a star dim, international researchers have identified the first extrasolar planet with a carbon and oxygen signature. While unlikely to be habitable, this gas giant adds to the menagerie of other worlds and their unusual properties.

Gem Sorting for the Next Earth
Topic: New Planets
01/21/04
Which star is most like our own Sun? This intriguing question offers a chance to test hypotheses about what places might make for a good Earth-like, habitable planet. The best found so far may well be the 37th most westerly star in the constellation, Gemini, called 37 Gem.
