They are hard to spot because they give out very little energy. Most of their radiation is in the infra-red.

Is a brown dwarf bigger than the sun?
No Brown Dwarfs are too small to be considerred a star.
How are brown dwarfs like Jovian planets?
Both of them have the same mass which is 13MJ Edit : As far as I know brown dwarfs have much more mass than Jupiter, and that's the biggest of the Jovian planets.
How does the brown dwarf make light and heat?
Brown dwarfs are heated primarily due to the compression of their interiors and are hot enough to glow. Some the the more massive brown dwarfs may also fuse deuterium, an isotope of hydrogen, for a short period after they form.
What is the color of the collest star?
The coolest stars are the Brown Dwarfs, so naturally, they're red. ("Red Dwarf" was already taken)
What are the stars called brown dwarfs made of?
A brown dwarf is an object that is not massive enough to be a star, yet it is more massive than planets. Basically it doesn't get hot enough for normal nuclear fusion (to convert hydrogen-1 into helium), but it can get hot enough to fuse deuterium (hydrogen-2) into heavier elements. Comments: I agree, except that I don't think brown dwarfs can fuse deuterium either.
What is the difference between brown dwarfs and Jupiter?
Brown dwarfs are more massive than the planet Jupiter.
Do brown dwarfs orbit Mars?
no
Is this true or false brown dwarfs white dwarfs and neutron stars are all kept from collapsing by degeneracy pressure?
True.
A dying star shrinks to this?
Dying stars eventually shrink into white dwarfs (which as they age eventually become red dwarfs and then brown dwarfs - but this takes an extremely long time).
Is a brown dwarf bigger than the sun?
No Brown Dwarfs are too small to be considerred a star.
What stars are cool and dim?
Brown dwarfs are failed stars, so they don't count. Red dwarfs are the kings when it comes to dimness

Very small stars that are usually old and running out fuel are called?
Those are dwarf stars, which start out as white dwarfs and as they (very slowly) cool, become red dwarfs and eventually brown dwarfs.
How does the brown dwarf make light and heat?
Brown dwarfs are heated primarily due to the compression of their interiors and are hot enough to glow. Some the the more massive brown dwarfs may also fuse deuterium, an isotope of hydrogen, for a short period after they form.
What word means hard to detect or describe?
The word that means hard to detect or describe is elusive.
What are the release dates for Robot Astronomy Talk Show - 2008 Twin Brown Dwarfs 2-1?
Robot Astronomy Talk Show - 2008 Twin Brown Dwarfs 2-1 was released on: USA: 11 March 2009
What particle did Chadwick discover in that was hard to detect because it had no electrical charge?
the paticle that was hard to detect was neutrons because it had no electrical charge.
