Where in the Milky Way would astronomers expect to find planetary systems other than our own?

Question

a. nebulae
b.black holes
c. supernovas
d. Cephaid stars

Answer 1

none of the above.

Answer 2

a. Nebulae are formed after a star has exploded, or when a star is near a star that has exploded. Either way, there is a considerable amount of debris which could coalesce to form planets, particularly if there is a star at the centre to attract it.

Our own solar system is conjectured to have formed as the result of a supernova explosion, these are the only explosions which are powerful enough to produce heavy elements in one location. So I suppose (c) is a possibility, given enough time afterward the explosion.
Black holes have such high tidal forces that no planets could form around them. Cephaids are variable stars, probably binary systems, which may be unstable, and are unlikely to have planets.

Answer 3

Eris, the biggest dwarf planet time-venerated, develop into found in an ongoing survey at Palomar Observatory's Samuel Oschin telescope via astronomers Mike Brown (Caltech), Chad Trujillo (Gemini Observatory), and David Rabinowitz (Yale college). We formally stated the call on 6 September 2006, and it develop into ordinary and introduced on 13 September 2006.

Answer 4

We’ve identified over 200 planets around other stars, but in many ways we know little about other solar systems. So none of your choices but if we go into the black hole and see light which is not possible then you find plantary system.
Hope this helps you. Nice trick question

Answer 5

All are poor choices. Of these poor choices, nebulae is the best, because new stars can form out of this material...but its still a poor choice. If this is out of a textbook, its a crappy book, and you can tell your teacher I said so.

Answer 6

around other stars, so none of the choices.
