Do scientists panic when they see unusual things?

Somebody asked me this Q recently...Would scientists go off into panic modes if something unusual happens - like stars alongside everything else except the Sun mysteriously vanished without a reason?

My reply was...

No! On the contrary scientists would be the last ones to panic. If something unusual happens the first reaction of majority of scientists would be ... "Oh, my, this is strange. Let me find the reason for it!"       ( There will always be a reason for everything that happens in this universe!)

This is how I react too!
First the scientists start thinking about all the possible scientific explanations for it. This is what goes on in their minds...

The disappearance of stars could be because of  something like a nebula we are passing through that blotted the stars out and if it is charged, it can damage the spacecraft and satellites surrounding the earth. How can we protect them? And how can we protect ourselves?

Or is it a super dense concentration of dark matter? 
If the sun was also gone, a possible effect on the upper atmosphere that made it opaque.

Until we found out what exactly happened most scientists would be busy trying to understand it and would not make any announcements.

Then they try to grab all the appropriate instruments available and try to investigate why it happened!

So generally, "excitement" would probably be the first emotion. They see an opportunity here to study things more closely and appropriately.

There's a tendency for scientists to ignore personal risk when faced with mystery. Curiosity is what drives them most of the time. You can compare it to that of photo-journalists faced with disasters or riots; they jump out without realizing the danger of it and act as though the camera makes them immune to whatever is on the other side of the lens. However, scientists take informed risks.
Scientists would probably be one of the few NOT going into a panic mode.

So a good number of scientists will be busy trying to take measurements of the darkness surrounding us and figure out what is causing it.

Then they would use their data to figure out if this darkness is dangerous to us, and what we can do to protect ourselves from it, or how we can use it to our benefit. Meanwhile they will continue to study it and collect more data. Eventually they will be able to make pretty good predictions about what the darkness will do in the next few years, or whether it will stay around or go away.

Good scientists don't have the time to freak out and panic. There's always something better to do or think about and work.

Watch this video that tells how scientists try to imagine things based on their knowledge when they cannot immediately test something that's found to be unusual :

Sometimes we come across some stories that tell about things falling down from cup boards etc. in homes and shops during nights. People attribute these things to 'ghosts'!

In my home too sometimes some things fall from shelves and cup boards. I don't believe in ghosts. So I don't panic but really go and investigate the reason for these things. Many times I found lizards that are chasing small insects that move around during nights responsible for these 'strange things' happening around the kitchen. And  I have observed some other interesting things too. The tall steel and German silver boxes in which we keep cereals, pulses  etc. sometimes go out of shape at the top when they fall down. When you use pressure to put the lid back on them, these misshapen boxes push the lids out and they come out with force as if somebody has taken them out and thrown on the flour!

This is how we do things.

Yes, there aren't any ghosts in my home!

On the other hand, what would superstitious people do? Quite the opposite to what scientists do! Need I add it here? I won't do that and will let your imagination run wild!
