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.

Voyager 2 engineers working to restore normal operations

Engineers for NASA's Voyager 2 spacecraft are working to return the mission to normal operating conditions after one of the spacecraft's autonomous fault protection routines was triggered. Multiple fault protection routines were programmed into both Voyager 1 and Voyager 2 in order to allow the spacecraft to automatically take actions to protect themselves if potentially harmful circumstances arise. At NASA's Jet Propulsion Laboratory in Pasadena, California, engineers are still communicating with the spacecraft and receiving telemetry.
