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.

Scientists explore outback as testbed for Mars

This week, scientists from NASA's upcoming Mars 2020 mission joined their counterparts from the joint European-Russian ExoMars mission in an expedition to the Australian Outback, one of the most remote, arid regions on the planet. Both teams came to hone their research techniques before their missions launch to the Red Planet next summer in search of signs of past life on Mars.
