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.

Astronauts less likely to faint on Earth if they exercise in space; findings may help others with fainting issues

Up to two hours of endurance and resistance exercises daily during a long space flight mission, combined with IV fluid replacement after landing, helps astronauts prevent dizziness and fainting during normal activity when they return to Earth. The study findings also have implications for a variety of people with health conditions that cause them to faint when standing up, and people on bed rest for long periods.
