Massive Stars and their approximate Size

Astronomers have found massive stars in the early universe, primarily located in distant galaxies that formed shortly after the Big Bang. These regions are often studied through advanced telescopes capable of observing very distant light, such as the Hubble Space Telescope and the upcoming James Webb Space Telescope. In terms of size, these monster stars can have diameters ranging from about 100 to over 300 times that of our Sun. The Sun’s diameter is approximately 1.4 million kilometers (about 864,000 miles), so these massive stars could be approximately 140 million to over 420 million kilometers (about 87 million to 261 million miles) in diameter.

Harvesting renewable energy from the sun and outer space at the same time

Scientists have demonstrated for the first time that heat from the sun and coldness from outer space can be collected simultaneously with a single device. Their research suggests that devices for harvesting solar and space energy will not compete for land space and can actually help each other function more efficiently.
