NASA sounding rocket to form blue-green and red clouds in space Thursday morning. Launch window opens 4:25 a.m. EDT (8:25 UTC). Backup launch day is June 30.
This map shows the projected visibility of the vapor tracers during the May 31 mission. The vapor tracers may be visible from New York to North Carolina and westward to Charlottesville, Virginia.

Sometimes called Barnard’s Runaway Star, it’s one of the best known stars in the history of astronomy and in popular culture.

First quarter moon will be July 1 at 00:51 UTC. Full moon will be July 9 at 04:07 UTC.
Chirag Upreti caught this image of the waxing crescent moon on June 25, 2017. He wrote: "The waxing crescent moon illuminated at ~6% descends behind the Eastern Sierra mountains as the radio antennae in the Owens Valley Radio Observatory actively scan the skies to reward human curiosity . The Earthshine (Da Vinci's glow) was noticeable even during the astronomical twilight when this image was taken, a beautiful perspective to witness a moonset."
Across the US Southwest – amid a record-breaking heat wave – fires that started in early June continue to burn.
NASA's Terra satellite collected this natural-color image on June 23, 2017. Actively burning areas are outlined in red. Image via NASA/Jeff Schmaltz LANCE/EOSDIS MODIS Rapid Response Team, GSFC.
Expert analysis showing how many people – and how much traffic congestion – can be expected along the path of the August 21, 2017 total solar eclipse.
The total phase of the March 20, 2015, solar eclipse as seen from the Svalbard archipelago in the Arctic. This is a composite of short, medium, and long exposures, as no single exposure can capture the huge range of brightness exhibited by the solar corona. The longest exposure in the composite captured the faint illumination of the Moon by earthshine, that is, sunlight reflected off the Earth. No filter was used during the exposures, as totality is about as bright as the full Moon and just as safe to look at. At all other times, though, a safe solar filter is required to observe or photograph the Sun. Credit: Reinhard Wittich
Not traveling to the centerline of the eclipse? Expect NASA images via 11 spacecraft, at least 3 aircraft, more than 50 high-altitude balloons, and the International Space Station.
This image of the moon crossing in front of the sun was captured on Jan. 30, 2014, by NASA's Solar Dynamics Observatory observing an eclipse from its vantage point in space.

June 24 new moon occurs on June 23 for the Americas. It’s a supermoon, but not the closest one of 2017.
A new moon is more or less between the Earth and sun. Its lighted half is turned entirely away from us. Image via memrise.com.
