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.

When a red dwarf dies does it make a nebula?

Yes, but it can also make a black hole or a white dwarf.


Does Jupiter or Saturn make its own heat?

Jupiter and Saturn both generate their own internal heat through a process called gravitational contraction. As the planets gravitationally shrink, the potential energy is converted into heat, keeping them warm despite their distance from the sun. This process helps sustain the intense temperatures and dynamic weather systems on these gas giants.


Where was the dwarf planet make make discovered?

The dwarf planet Haumea was discovered at the Palomar Observatory in California, USA, in 2004. It was identified by a team of astronomers, including Chad Trujillo, Michael E. Brown, and David Rabinowitz. Haumea is notable for its elongated shape and rapid rotation, making it one of the most unique objects in the Kuiper Belt.


Is the moon made of plasmas?

no because the light that comes from the moon is from the sun. so it doesnt make its own heat or light. so no


How can a star be bright and very cold?

A star can appear bright and yet be cold if it is large and emits light predominantly in the infrared spectrum, which is less perceptible to the human eye. For example, a brown dwarf is a type of celestial object that is too low in mass to sustain hydrogen fusion like a typical star but can still emit significant thermal radiation due to its heat. This can make it appear bright in infrared observations while being relatively cool compared to hotter stars. Thus, brightness does not always correlate with temperature, especially when considering different wavelengths of light.
