Summer is officially here! The summer solstice is this Sunday, June 21st. It marks the first official day of summer. The sun appears to stand still in the sky a few days before and after the solstice. June 21st is also the longest day of the year. This is because the earth revolves around the sun on a tilt. Texas is in the northern hemisphere. We are tilted toward the sun in the summer and away from the sun the  in winter. Be sure to go outside an enjoy the beautiful sunshine!
