Since all objects are ‘weightless’ for an astronaut in orbit, is it possible for astronauts to tell whether an object is heavy o

r light? Think about it, think of newton’s laws, the equations and then explain your reasoning.

W=gm
where g - gravitation 
m - mass
w - weight
as gravitation equals to zero, multiplying by 0 gives W=0
It is not possible to tell whether and object is heavy or light

Well, while they're in orbit, nothing is 'heavy' and nothing is 'light'.
They're all weightless.

I think you're really asking:  Can the astronaut tell which objects will be
heavy and which ones will be light if they go back down to Earth ?

The answer is a resounding 'Sure' !

The weight of an object on Earth is (its mass) x (acceleration of gravity).
So the objects with a lot of mass will be heavy, and the objects with less
mass will be lighter.

How can the astronaut determine the mass of the object hanging there
in the air in front of him ? 
All he has to do is give it a push.  It'll accelerate away from him (and he
will accelerate away from the object). 
Newton's 2nd law tells us that  F=mA, so the acceleration will be

                             (the force he exerts) / (the mass).

An object with small mass will zip away from him, and it'll be light
down on the surface. 

An object with large mass will accelerate slightly, start moving slowly,
and it'll be heavy down on the surface.

What happen when a star dies?
Vera_Pavlovna [14]
It depends on the size of the star. If it's size was normal then it cools down into White dwarf, then a black dwarf. If a really huge star dies, then we can see a "Supernova" from that.

Hope this helps!!

What is a partial and total lunar eclipse?
Minchanka [31]

Partial Lunar Eclipse:

A partial lunar eclipse is when the earth gets between the Sun and Moon. However, all three bodies are not in alignment meaning we are able to see some more like part of the moon's surface as it moves in route of the Earth's shadow.

Total Lunar Eclipse:

The three celestial bodies are perfectly aligned which allows for the earth to completely block the sun's rays from hitting/reaching the moon. The sun is positions is in back of the Earth which then causes the shadow of the earth to be cast on the Moon covering the moon completely. When that happens you get the phenomenon called a total lunar eclipse.

Hopefully this helped and good luck.
