While the Sun has been burning for about 4.6 billion years, Earth has evolved over this time, developing an atmosphere and life. 9 One of the most notable differences between the Sun and Earth is their size and composition. The Sun's diameter is about 109 times that of Earth's, and it...

The most penetrating component of these are muons, which can be detected at the surface of the Earth but also at underground or underwater detectors. In order to reach the KM3NeT/ORCA detector [1] at a depth of 2500 ms below sea level [2], vertically down-going muons need a minimal ...
S-054 images were recorded on 70 mm film that was brought down to Earth by the astronauts, developed, and – at least for the CfA – printed onto transparencies of some 25 cm in size (as far as I recall), stored in drawer after drawer in a small room off CfA’s hallways. I ...

The planet, which is about 60 percent bigger than Earth, is located 1,400 light years away in the constellation Cygnus. It was discovered by astronomers using NASA's Kepler space telescope and circles a star that is similar in size and temperature to the sun, but older. ...
Assuming an Earth-directed isotropic distribution, these Discussion The comparison between Hinode and ACE observations obviously has large uncertainties because ACE makes measure- ments corresponding to the features that it actually sees along the Sun-Earth line and projected back to the surface, but ...
