In titles in English, we tend to uppercase all nouns, pronouns, verbs, adjectives, and adverbs, but not articles, prepositions, or conjunctions, unless the latter is 4 letters or longer. The latter rule depends on the style guide you are following, but the first rules should be followed in most cases.

Thise topic is lessof the article is not very interesting, but i wouldI like to read in English.

You wouldn't use "this" since you haven't yet mentioned what the topic is. "Less" is for a comparison, which was not done here. You need a comma before "but" because the phrase that follows "but" is a full sentence. "Would" is ok here, but it is a bit more natural without it because you did in fact read the article already, so "would" makes it sound like something you haven't done that yet and are aspiring to do this instead.

The sScienticsts are lookanalyzing many tiny rocks, and they are searchdetermining their age.

You can't use "the" because you are not referring to scientists that you already mentioned. You could use "the" though if you specify which scientists you are referring to. I.e., "The scientists discussed in the article..." "Looking" would need to be followed by "at" in this context, but that verb is still not "strong" enough: Scientists analyze and evaluate, whereas "look (at)" is a more generic verb. "Search" has a similar issue here, which would be "searching for," when followed by a noun like this, but again, the verb is a not the best for the context since we are discussing the actions of scientists.

The answer able to help todata will help us to better understand the eEarth.

"Data" is better. "Answer" is not as good because there was no "question." And you want to say "better understand" rather than just "understand" because there are still things we won't know about Earth once we have this data. "The earth" is OK, but "Earth" is more clear, since we know you are discussing the planet and not dirt.

These rocks are very important to the scientists.

"Would like" est correct, mais si tu traduis "je voulais" dans cette phrase, on utiliserait plutôt le passé en anglais.

The scienticsts are looking at many tiny rocks and they are searchingtrying to determine their age.

On dit toujours "look at" quelque chose. De la même façon, quand on cherche quelque chose, on dit toujours "search for" quelque chose. Mais "search for" ne va pas très bien dans cette phrase.

The answer able to help tocould help us/them understand the earth.

It sounds a little vague when you just say "help to understand," and would probably sound better if you choose either "us" (help us, humans, understand the earth) or "them" (help scientists understand the earth)

It'Scientists can study this because of the first astronaute who went on moon, he bring this rocks, that the scientics can studieto the moon and brought back these rocks.

For them, is itThey are very important.

Si tu parles des rochers qui sont importants, on dirait "they" ici.

Do you mean you don't know what else to write? Or don't know what to write next time? "Write again" isn't clear. Apologies if I changed the meaning of what you wanted to say.
