Novas

Normally it is known as the supernova's progenitor star.

The two factors that determine how bright a star looks from Earth are its intrinsic luminosity (actual brightness) and its distance from Earth. Stars that are more luminous and closer to Earth will appear brighter in the night sky.

It will all depend on it's mass, temperature and metallicity. The larger the star, the shorter it's life span will be.

It can be millions to billions of years.

Not all stars explode, some will just shred their outer layers and slowly cool off. This is what will happen to out Sun.

No, our sun does not have enough mass to undergo a supernova explosion. It will eventually exhaust its nuclear fuel and expand into a red giant before shedding its outer layers to form a planetary nebula. The remaining core will cool down and become a white dwarf.

Yes, when a star undergoes a nova, it expels material into space, which can eventually form a white dwarf. A white dwarf is the remnant core of a star that has exhausted its nuclear fuel and collapsed under gravity. Novae are different from supernovae, which are more energetic and can leave behind other remnants like neutron stars or black holes.

It's highly unlikely. Antares is not likely to go supernova for at least a million years. However, because of it's distance from us - 600 light years, it may have already gone supernova and we just haven't seen it yet.

The two factors that determine how bright a star appears from Earth are its intrinsic brightness (or luminosity) and its distance from Earth. Intrinsic brightness refers to the amount of light a star emits, while distance affects how much of that light reaches us. Closer, more luminous stars appear brighter in the sky.

1. Power off the Nova by holding the power button for two seconds until you see "Power Off" on the screen. Choose the "power off" option and then press the "Ok" button. Let the device completely power down before you continue with the next steps. At this time also remove any SD card you might have inserted into the device.

2. Press and hold the volume + button. While still holding this button, press down on the power button. You will then see a screen that says Pandigital. This is the boot screen.

3. After the device boots up you will go to a black screen with triangle, press volume + button and the power button. What should come up is a screen with blue text, this is the system recovery screen. While on the system recovery screen, press the volume - button until "wipe data and cache" is highlighted. Press the power button to select this option

4. Press the volume - button until "Yes -- delete all user data" is highlighted. Press the power button to select this option.

5. The device will reformat and return to the system recovery screen.

6. "Reboot system now" should be highlighted by default. Press the power button to select this option. (this is directly from pandigital customer service)

No, red dwarf stars are not made from supernovae. Red dwarf stars are low mass stars that form from the gravitational collapse of gas and dust in interstellar clouds. Supernovae, on the other hand, occur when massive stars reach the end of their life cycle and explode.

Gamma rays are a form of electromagnetic radiation, and thus they travel at the speed of light.

If a star is one light year away, it will reach Earth in one year.

Rigel is approximately 120,000 times brighter than the Sun. This high luminosity is due to Rigel's much larger size and higher temperature compared to the Sun.

A galaxy is a huge group of stars that form a spreading spiral. Our own Milky Way galaxy is an example of a spiral galaxy.

Depending on the distance between the binary pair, it is possible for the white dwarf to draw gas from it's companion causing the star to reach the Chandrasekhar limit causing the white dwarf to explode as a nova or a type La supernova.

A red dwarf star has a surface temperature that ranges from about 2,500 to 4,000 degrees Celsius (4,532 to 7,232 degrees Fahrenheit). This is cooler compared to other types of stars like our sun, which has a surface temperature of around 5,500 degrees Celsius (9,932 degrees Fahrenheit).

Massive stars that are at least eight times more massive than the Sun end their life as a supernova. During the explosion, these stars release a tremendous amount of energy and can briefly outshine an entire galaxy.

Old craters typically have more erosion, with smoother edges and a shallower depth compared to new craters. New craters have sharp, well-defined edges with steep walls and a more prominent central peak. Additionally, the presence or absence of overlapping craters can also help distinguish between old and new craters.

The description matches that of a neutron star, which is formed after a supernova explosion of a massive star. Neutron stars are incredibly dense, with matter packed tightly together. Due to their high gravitational pull, a small amount of neutron star material would have an extremely high mass.

The core of the Sun is the part responsible for giving off heat and light through nuclear fusion reactions. This is where hydrogen atoms are converted into helium, releasing large amounts of energy in the form of heat and light.

A supernova can be billions of times brighter than a nova. Novas occur on the surfaces of white dwarf stars and release energy comparable to millions of hydrogen bombs, while supernovae represent the explosion of an entire star and can briefly outshine entire galaxies.

when a star is at the end of its life(depending on mass) a star will sponaniously explode into a supernova. or it will collapse into a black hole.

The closest star to Betelgeuse is approximately 643 light-years away. This star is located in the star cluster known as the Orion Nebula, where it is part of a group of young, hot stars.

after the star implodes an explodes it becomes a white dwarf or a black hole

Because it has used up all of it's fuel and has nothing left to convert into energy (unless it can accrete additional fuel from a companion star).

Brightness is related to luminousity and distance. On Earth, the brightest thing would be a nuclear explosion. In space, the brightest thing would be a supernova, but it all depends on the distance from it.

The universe is a vast and complex system that consists of stars, planets, galaxies, dark matter, and dark energy. It is organized into a cosmic web structure, with galaxies clustered along filaments separated by voids. At the largest scales, the universe appears homogeneous and isotropic, following the principles of cosmological models such as the Big Bang theory.
