[DM] - Alma Telescope Takes First Pictures - Page 5

You can watch more about ALMA from their podcast at the ESO website: http://www.eso.org/public/esocast.html
or in a browser at http://www.space.com/13143-complex-o...ses-image.html



During the Year of Astronomy's 100 hour 'Around the World in 80 Telescopes' webcast they had interviews with scientists working on the ALMA high up in the Chilean mountains.

yes but wouldn't this technology make it easier to spot them?

I doubt it. Different programs like Alma and Kepler are designed for different functions. There probably aren't many parallel functions between them.

We're more likely to use infrared to view the light absorbed by the planet's atmosphere. Detecting a planet by it passing between us and the star is very hard though. The chances of everything aligning correctly is very slim. We're more likely to detect planets by the shifts in wavelengths of that star's light due to a massive object orbiting around it. As the planet orbits around the star, it tugs on the star causing the light to shift wavelengths as can be measured in a spectrograph.

The VLT array, which is another radio telescope antenna like ALMA, has been used to discover exoplanets with similar techniques.

We have actually "seen" a few planets directly using a vortex coronograph:

Its just crazy how these things happened millions and billions of years ago. And it will be billions of years before anyone or anything observes what is happening today in 2011. Assuming light speed travel is never accomplished.

How could we conceivably mess up something that is infinite?

Not really massive images sadly so the res isn't great. Best I could find though.


um, 4005x4005? That'll do nicely. Well done.
