SUMMARY

Astronomers in Chile have potentially captured the first direct image of an extrasolar planet orbiting the star 2M1207, located 230 light-years from Earth. This star is significantly smaller and fainter than the Sun. The evidence supporting the identification of this object as a planet is promising, but further observations over the next one to two years are necessary to confirm its status through relative motion analysis against its parent star.

PREREQUISITES
  • Understanding of astrophysics and celestial mechanics
  • Familiarity with observational astronomy techniques
  • Knowledge of the characteristics of stars and planetary formation
  • Experience with data analysis in astronomical research
NEXT STEPS
  • Research the methods used in direct imaging of exoplanets
  • Learn about the characteristics of the star 2M1207 and its significance
  • Study the techniques for measuring relative motion in astronomical objects
  • Explore the implications of discovering extrasolar planets on our understanding of the universe
USEFUL FOR

Astronomers, astrophysics students, and anyone interested in the discovery and study of exoplanets will benefit from this discussion.

"Astronomers working in Chile think they may have taken the first direct image of a planet circling another star.
The star, called 2M1207, is 230 light-years away and is very much smaller and fainter than our own Sun."


I'm gazing at this little red dot and here seems so near, but is really so far away...
OK. Do you think that is really a planet?

Here's a more detailed http://www.eso.org/outreach/press-rel/pr-2004/pr-23-04.html .

There's quite a bit going for this one as a real planet ... but, as they say in the PR, it will take another year or two for any significantly different data to strengthen the case one way or the other - how does this object move (on the sky) wrt the apparent parent? If it's not a planet, it will very likely show clear relative motion in that time.
