In summary, the conversation discusses the speaker's university project on the search for extrasolar planets, specifically Earth-like planets or moons. They are seeking sources for information and mention a few helpful resources, including a website with 3D animation. The speaker expresses gratitude for the sources and plans to begin the project soon.

Hi again, one and all. Been a while.

As part of my 'scientific communications skills' malarky at uni we have to produce myriad things (review article, powerpoint, governmental brief, etc, etc) on the subject of the search for extrasolar planets. We're focusing (probably) largely on the search for Earth-like planets or moons in solar systems other than our own. It's at very early stages at the moment and we're largely just collating as much information on the subject as possible. No real problems, but I thought if anyone knew of any sources that were particularly special they might push me in the right direction, just in case we miss it.

Thanks in advance,

El Hombre

Thanks EM. Will be starting this very shortly so it'll come in very handy.
 

1. What are extrasolar planets?

Extrasolar planets, also known as exoplanets, are planets that orbit stars other than our Sun. They are located outside of our solar system and have been discovered through various methods such as transit observations and radial velocity measurements.

2. How many extrasolar planets have been discovered?

As of October 2021, there have been over 4,500 confirmed exoplanets discovered. However, there are thousands more potential candidates that are still being studied and verified by scientists.

3. Can extrasolar planets support life?

It is possible that some extrasolar planets could support life, but this has not been confirmed yet. Scientists look for certain characteristics in exoplanets, such as the presence of water and a suitable distance from their star, when determining their potential for habitability.

4. How do scientists detect extrasolar planets?

There are several methods used to detect exoplanets, including the transit method, which measures the decrease in a star's brightness as a planet passes in front of it, and the radial velocity method, which detects the wobble of a star caused by the gravitational pull of an orbiting planet.

5. Why are extrasolar planets important to study?

Studying extrasolar planets can provide valuable information about the formation and evolution of our own solar system. It can also help us understand the diversity of planetary systems and potentially provide insights into the possibility of life beyond Earth.
