When the Earth, Moon and Sun Align. By Kevin Matyi. On Aug. 21, 2017, a total solar eclipse will cross the full continental United States along a narrow, 70-mile-wide path from Oregon to South Carolina. The last total eclipse in the U.S. was in 1979. And the last total solar eclipse that crossed the entire continental U.S. happened in 1918.
NASA SOHO shares the scary sound of the Sun. Interestingly, the sound of the Sun is extremely loud. The sound that reaches the Earth from the Sun has been calculated to be around 100 decibels by the time it reaches the Earth as per data from American Academy of Audiology. That means right next to the Sun, the sound will be so loud that it would
Photic sneeze reflex. The photic sneeze reflex (also known as Autosomal Dominant Compelling Helio-Ophthalmic Outburst ( ACHOO) syndrome [1]) is an inherited and congenital autosomal dominant reflex condition that causes sneezing in response to numerous stimuli, such as looking at bright lights or periocular (surrounding the eyeball) injection.Follow along with our birding-by-ear series to learn how to better ID birds through their vocalizations. In part 2, Bird and Moon creator Rosemary Mosco takes you through the various sounds you hear and what they mean to birds (and to birders). To catch up, check out part 1 , part 3 , part 4 , part 5 , part 6 , part 7, and part 8.After eight minutes, however, the lights would go out. The Moon will no longer shine upon us (it receives its light from the Sun), so our only source of light will be that of the celestial objects. Mercury and Venus will have seemingly disappeared from our optical telescopes — they will no longer be illuminated by the Sun. If you've got the volume cranked to 88 decibels, then cut your listening time down to 4 hours. At its loudest, an MP3 player pumps out 105 decibels that's100 times more intense than 85 decibels pJUb.
