I need a good grade 9 astronomy topic for science project?

There are so many topics you could do:

stars

Star clusters

galaxy clusters

supernovae

white dwarfs/red dwarf/brown dwarfs

Nebulae

Black holes

Quasars

Neutron Stars (Pulsars and Magnetars)

Quasars and Blazars

Gamma rays

The origin of the Universe

Dark energy and Dark Matter

Nuclear fusion is a massive star

Planetary formation and dwarf planets

Speed of light

Galaxy formation

Comets/meteors/asteroids

Electromagnetic spectrum (Red shift and Blue shift)

Moon phases and eclipses

Einsteins general theory of relativity (or the special theory)

Personally I would do "star crossed" it has to do with the way the stars are aligned, it may not be about planets and such but I think its interesting. Message me if you need any help on it (if you pick this topic of course)

"Star-crossed" or "star-crossed lovers" is a phrase often describing a pair of lovers whose relationship is said to be doomed from the start, though also encompassing different meanings. The phrase is astrological in origin, stemming from the belief that the positions of the stars ruled over people's fates. To describe a relationship as "star-crossed" is to say that it is "thwarted by a malign star",[1] or that the stars are working against the relationship. The phrase is best known from the play Romeo and Juliet by the Elizabethan playwright William Shakespeare.

oooooo soo much to choose from, how about other galixies or the kepler mission somthing going on currently, they shot a telescope out far to we can observe some other places outside of the milkyway. oooorrr how about the astroid search program, a program where nasa and many other people and students look for astroids that could hit our planet. orr give a example about how far everything is in relative to the size of space, for example try to see the universe as a small area instead of somthing huge.

Do a Science Project on Black Holes. Thats what I did.

check out nasa.gov maybe just searching the site can help you pick a topic and provide you with information and a photo..

unfortunately grade nine was a long time ago for me.

good luck

I'd do mine on pulsars. Pulsars are quickly rotating neutron stars that emit a beam of radiation. They are very interesting and have always fascinated me.

Do it on a planet. The planet that has a bunch of moons, sorry i don't no the name of that planet..... oops
