Grammar explanation
We use the present perfect simple (have or has + past participle) to talk about past actions or states which are still connected to the present.
Unfinished time and states
We often use the present perfect to say what we've done in an unfinished time period, such as today, this week, this year, etc., and with expressions such as so far, until now, before, etc.
They've been on holiday twice this year.
We haven't had a lot of positive feedback so far.
I'm sure I've seen that film before.
We also use it to talk about life experiences, as our life is also an unfinished time period. We often use never in negative sentences and ever in questions.
I've worked for six different companies.
He's never won a gold medal.
Have you ever been to Australia?
We also use the present perfect to talk about unfinished states, especially with for, since and how long.
She's wanted to be a police officer since she was a child.
I haven't known him for very long.
How long have you had that phone?
Finished time and states
If we say when something happened, or we feel that that part of our life is finished, we use the past simple.
We visited Russia for the first time in 1992.
I went to three different primary schools.
Before she retired, she worked in several different countries.
We also use the past simple for finished states.
We knew all our neighbours when we were children.
I didn't like bananas for a really long time. Now I love them!
Past actions with a result in the present
We can use the present perfect to talk about a past action that has a result in the present.
He's broken his leg so he can't go on holiday.
There's been an accident on the main road, so let's take a different route.
They haven't called me, so I don't think they need me today.
Again, if we say when it happened, we use the past simple.
He broke his leg last week so he can't go on holiday.
However, we often use the present perfect with words like just, recently, already, yet and still.
We've recently started going to the gym.
She's already finished season one and now she's watching season two.

Hello JoAp,
All the sentences are correct. The differences are really ones of emphasis,
Sentence 1: The information from Sarah is recent; it is still 'news' to you. Speaking in your sleep is still a problem/issue.
Sentence 2: The information from Sarah is not seen by you as 'news'. either she told you some time ago, or you consider it something not relevant to your present. For example, you may not be interested in acting upon the information – you don't care that you speak in your sleep. The change from I'm talking to I've been talking does not make any difference in this context.
Sentence 3: This is a combination of 1 and 2; see the relevant parts of the descriptions above.

Hello Kapil Kabir,
I think the clearest way to expain this is to compare two version of your sentence:
In sentence 2 the possessive India's refers to both people. It is clear that both the prime minister and the president are Indian.
In sentence 1 the possessive form describes only 'President'. The prime minister could be from India or from another country. We would only know this from the context. The article here must refer to another mention of the prime minister earlier in the text.

Hello Kapil Kabir,
It's difficult to make generalizations about grammar, and especially without specific examples in context. To me the general rule of using the present perfect sounds correct, but this is not to say that it's always the only possible form.
I'm afraid I can't explain the sentence you ask about. I don't think I'd say 'the past few years' -- instead I'd probably say 'in recent years'. I wouldn't say the sentence is wrong, but I'd suggest changing that last part.
All the best,

Hello Kapil Kabir,
It looks to me as if some words have been omitted from the sentence you ask about. I'd need to know the context to give you an exact answer, but it sounds as if the text this sentence is from probably discusses two or more images before this sentence -- for example, maybe it's two images of two comets, one of which is relatively close and the other is further away.
The sentence you ask about indicates that it's talking about the more distant comet, which is represented in the first image. In other words, it's another form of 'The first image was [a photograph] of the more distant [comet].'
Hope this helps you make sense of it.
All the best,
Kirk
