June solstice is the time when the Northern Hemisphere is
tipped most specifically toward the Sun and gets the most direct daylight. It
happens around June 21 (also called summer solstice) on the day where the Sun
takes after its longest and most elevated way through the Northern Hemisphere
sky and its shortest way through the Southern Hemisphere sky.

Explanation:
Measuring the amount of deu terium in the universe allows us to set a limit on the density of ordinary matter of universe. Density of the universe is about 9×10-27 kg m-3, because of the way in which deu terium was created in the Big B ang, an exact measurement of the amount of deuterium would allow scientists to set limits on the models of the great explosion.
