“Two things contribute to the moon being visible in daylight. First, it is bright enough that its light penetrates the scattered blue light of the sky. If you're looking at exactly the right spot with a telescope, you can also see the planets Mercury, Venus, and Jupiter in daylight, plus a few of the brightest stars (though few casual observers can actually pull this off). Secondly, the moon must be high enough in the sky to be visible.” via @space.com
“Neon, along with helium, argon, krypton and xenon, make up the group known as noble gases. All noble gases conduct electricity, light up when a current runs through them, and are odorless, colorless and monatomic (exist as individual atoms). Today, the majority of the lights you see in many places, such as on the Las Vegas strip, are made from mercury and argon and colored with phosphors.” Via @live_science #chemistry #scienceisfun #scienceisreal #scitechkids
