What are differences between spiral and elliptical galaxies?
Spiral galaxies have arms spiraling out from the central bulge of the galaxy and contain newer stars and has more gasses to form new stars.
Elliptical galaxies are normally formed after spiral galaxies merge. The formation is an elliptical mass of stars without any arms. When galaxies merge, the process destroys gasses needed to form new stars. So in an elliptical galaxy we would notice more older stars and less stars in the process of forming.
Don't listen to banana. he is plagiarizing.
lue and jishka girl you guys are the same people and you aint the boss yall dont like this site leave this site nd dont come back find your own or create a websit idio t
The brain pop movie called 'Galaxies' should help solve your problems
silly sally is right. I hate how people pretend to be different people on sites or pretend to be something they aren't. And although "Jiskha Girl" isn't wrong, you aint the boss of anybody. Stop pretending to be someone you ain't just to get the likes and agreements of others through trickery.
Spiral galaxy is a special kind of galaxy as described by Hubble in his work. It consists of a flat, rotating disk containing Stars, gas and dust and a central concentration of stars known as bulge. These are surrounded much fainter halo of stars many of which reside in globular clusters. They are named for the Spiral structures that extend from the center to the disk. The spiral arms are ongoing sites of formation of stars and are brighter than the surrounding disk because of young hot OB stars that inhabit them. Together with Irregular galaxies they make about 60% of Local Universe.
TF IS THIS CRAP
Banana found that off a website but its very helpful!! ^^
Thx so much guys!
thsnks peeps
Here I can give you guys the answers for this just PUT IT IN YOUR OWN WORDS Because then you would get in trouble or you will get ex-spelled by your teacher and we can also be in the same class so when the teacher is grading she/he will have to talk to both of us and your parents might ground you TRUST ME IT"S HAPPENED TO ME BEFORE I don't want to get anyone in trouble
18. spiral galaxies are bright elliptical galaxies are dim.
Spiral galaxies are hotbeds of star formation but elliptical galaxies aren't nearly as prolific because they contain less gas and dust which means fewer new and brighter stars are born.
19. When meteoroids enter Earth's atmosphere or that of another planet like Mars at high speed and burn up the fireballs or shooting stars are called meteors When a meteoroid survives a trip through the atmosphere and hits the ground it's called a meteorite.
20. Venus is only a 30% closer to the Sun than Earth.
I need help
I'm not trying to start an argument or target anyone, but, honestly "Jiskha Girl" and "E340" are right. This website had no intent to become a place where people just give others a cheat sheet. It's meant for studying.
Also, please don't just copy and paste what a site says. In some places, it's a crime, and can at least get you punished.
I tried getting into brain pop and searching Galaxies and I tried logging into bran pop and it says my username and password are both wrong so I can't watch the video.
Ok. Many people that gave answers, like Banana, were just DESCRIBING the differences between the galaxies, not giving answers. Silly Sally, Little Miss No Name, people on this site, though I am guilty of doing this myself (using and giving answers), are supposed to HELP not give answers. I’m just stating facts, pls don’t come at me 😩🥺
Why does my name keep changing to "Anonymous"!!!
Very well said Jiskha Girl! :) "claps"
I agree, this is a helping site, not a cheating site. Just try your best guys and if you still need help, just ask and we are here to help! :)
Just watch the "BrainPOP" video called "galaxies" and write in your own words what you believe are the differences and similarities are between Spiral and Elliptical Galaxies. It is not that hard. :) Do not cheat guys, this is a HELPING site, they HELP CHECK YOUR ANSWERS, NOT to GET ANSWERS.
Just try your best with the sites provided within the unit and the site Ms. Sue provided above. If you have any further questions, we are more then happy to assist you on this site. Have a nice day! :)
Surely you can do this. Just look at them.
If you need someone to critique your work, post it. http://skyserver.sdss.org/dr1/en/proj/advanced/galaxies/characteristics.asp

Together with Irregular galaxies they make about 60% of Local Universe. E.g.- NGC1300, UGC12158.
Elliptical galaxy is a galaxy having an approximately ellipsoidal shape and a smooth nearly featureless brightness profile. They range in shape from nearly spherical to highly flat and in size from hundreds millions to over one trillion stars. Most Elliptical galaxy are composed of older, low mass stars, with a sparse interstellar medium and minimal star formation actvity. They are surrounded by a large number of globular clusters. They are believed to make up approximately 10-15% of the galaxies in our local Universe. E.g.- MACSG-1423, Maffei 1 .
