Betelgeuse, a red supergiant star in the constellation of Orion, is known to be variable in brightness. It has exhibited fluctuations in its light output over time, causing it to appear brighter and dimmer to observers on Earth. This variability is due to the star's complex internal processes and is a characteristic feature of certain types of stars.

What does lodestar mean?

"Lodestar" refers to a guiding principle or person, such as a North Star that provides direction. It is often used metaphorically to describe something or someone that serves as a constant and reliable point of reference.


What does northern star mean?

A "Northern Star" is a term used to describe a guiding principle or a constant source of guidance, inspiration, or hope. Just as sailors use the North Star for direction, people may look to their own "Northern Star" for guidance in their lives.


What is the meaning of the Nordic Star?

The Nordic Star, also known as the Northern Star or Polaris, symbolizes guidance, direction, and stability. It is often associated with finding one's way in life and staying true to one's path even in the darkest of times. In Nordic culture, it is seen as a symbol of hope and a constant presence in the night sky.


Why does a star's gravity increase when it gets smaller?

A star's gravity increases when it gets smaller because the mass of the star remains constant while its size decreases. This results in the gravitational force becoming stronger as the distance between objects reduces, following the inverse square law of gravity.


What is the temperature of a star whose maximum light is entitled at a wavelength of 290nm?

The temperature of a star can be calculated using Wien's law. Given the peak wavelength of 290nm, we can use the formula λmax = b/T, where b is a constant (2.898 x 10^-3 m K) to find the temperature of the star. In this case, the temperature would be approximately 10,000 K.

What is the acceleration of light from a star?

The speed of light is constant in a vacuum and is approximately 299,792 kilometers per second. Light from a star travels at this speed from the star to Earth without acceleration.


How would you work out the Hubble constant if the earth is 12.5 billion years old?

The Earth is not 12 billion years old. It is more like 5 billion years old. Hubble's constant cannot be determined from the age of the Earth. Hubble's constant describes how fast the universe is expanding. It can be determined by looking at the redshifts of stars that are a known distance away. From the redshift, one can determine the velocity of the star. Then Hubble's constant is defined as follows: v=Hd where v is the velocity of the star, H is Hubble's constant and d is the distance to the star. The current accepted value of Hubble's constant is about 71 km/s/Mpc.

Why the sun considered as a star?

The sun is considered a star because the sun IS a star. It is a huge ball of hot gases undergoing constant nuclear reactions, and releasing gigantic amounts of light, heat and various particles.


What is the meaning of these it is a star to every wandering bark?

This is a phrase taken from Shakespeare's Sonnet 116. The term "bark" refers to a sea-vessel, a ship. The star to which this phrase refers is the "North Star", the star by which sailors would orient themselves in lieu of a compass. Therefore, the phrase is speaking of something that is true, constant, and ever-dependable in the midst of struggle or confusion in life. In Shakespeare's Sonnet 116, this constant he is referring to is Love.
