I've never even heard of Cthonian planets. How many of those have been discovered, and how can they continue to stay in orbit and not fall into the star? If they migrated too close, wouldn't the star just pull them in?
You mention that one of the main goals is to find an earth-like inhabitable planet which has the right temperature to hold liquid water. How will astronomers know if an exoplanet is suitable for life? Will they use new technology to determine this?
I'm not sure how astronomers will know if exoplanets are suitable for life, but I do know they are using NASA's Kepler Spacecraft to detect exoplanets and the technology needed to detect life is still unknown.
I think it would be really interesting if life was discovered on these planets, and I don't see a reason why there isn't other planet out there that have life. And it probably would change life to an extent, but all great discoveries do I'd imagine.
You stated that Pulsar planets form after the event, Do you mean the event of orbiting? if so how does a Pulsar planet form, just by orbiting the star ?
In your presentation, you mention "the first exoplanet discovery was in 1992 when Dr. Alexander Wolszczan discovered two planet sized objects orbiting a pulsar." Was Dr. Wolszczan specifically looking for exoplanets or was he looking for something else? How did he make this discovery is essentially what I am asking.
I'm not sure if Dr. Wolszczan was specifically looking for exoplanets, but he was working with Dr. Dale Frail in Puerto Rico when they discovered the first exoplanets.
You mentioned that free floating planets do not orbit a star. Is there a chance that these planets could collide with another; if so has any been reported
In your presentation, you described the different types of planets. Of the types of planets you described, what is the most common type?
ReplyDeleteGas giants are the most commonm they're also referred to as mini-neptunes.

What classifies a pulsar star?
ReplyDeleteA pulsar star is the remnant of a dead star.

ReplyDeleteA Cthonian planet is hypothetical at this point.

How far away was the first exoplanet?
ReplyDeleteThe first exoplanet discovered is about 50 light-years away.

DeleteWhat is your opinion for finding new life on these exoplanets? Do you think there is hope to? Would it change the way we live today?

ReplyDeleteThat depends on the planet, but some are actually low mass white dwarf stars who have had their mass stolen by the pulsar that they orbit.

DeleteI'm curious to know which method for discovering exoplanets is more effective for astrologists and which one is the least effective?
