Green Lights Surround Bangkok at Night

NASA Earth Observatory

Thursday, May 17, 2018: As with most big cities seen from the International Space Station by night, the streets of Bangkok glow with bright yellow lights, revealing details about the city's structure and populations. But perhaps even more striking are the enormous clusters of green lights gleam in the surrounding waters. These lights come from hundreds of fishing boats in the Andaman Sea and the Gulf of Thailand, as fishermen use these green lights to attract plankton and fish. — Hanneke Weitering

Victor Rogus

Monday, May 21, 2018: Two days after the new moon of May, a thin sliver of the waning crescent moon joined the bright planet Venus in the evening sky. Astrophotographer Victor Rogus captured this photo of their conjunction from Arcadia, Florida Thursday (May 17) night as the moon passed about 6 degrees south of Venus. "The pair struggled for my attention through mostly cloudy Florida skies," Rogus said. "Still, a very beautiful sight in the west as the sky darkened." — Hanneke Weitering

This long-exposure image shows the rocket's trajectory as it pierced through a layer of clouds and soared to space. The rocket delivered into orbit a Cygnus cargo vessel as packed with more than 3 tons of crew supplies and science experiments. It will arrive at the space station on Thursday (May 24). — Hanneke Weitering

Wednesday, May 23, 2018: Jupiter looks a bit peculiar in this recent image taken by NASA's Juno spacecraft. Juno was looking at Jupiter's southern hemisphere after it completed its 12th close flyby of the planet on April 1. The unique angle of the image creates the illusion that the Great Red Spot, an enormous storm that swirls in Jupiter's southern hemisphere, is located in the northern hemisphere. — Hanneke Weitering

These islands line the eastern limit of the Philippine Sea. — Chelsea Gohd

Wednesday, May 30, 2018: Behind the blue-hued swirling galaxy that seems to sparkle in the lower left of this image, a galaxy cluster can be seen. This image, taken by the Hubble Space Telescope, shows the galaxy cluster known as SDSS J0333+0651. Galaxy clusters, and images like this, can help astronomers to better understand the distant/early universe. — Chelsea Gohd

Curiosity Rover Photographs a Hole it Drilled


Thursday, May 31, 2018: NASA's Curiosity Rover used it's Mast Camera (Mastcam) to photograph the product of its new drilling technique. Seen here on Sol 2057, or May 20, in a target known as "Duluth," Curiosity used its new technique to drill a 2-inch-deep hole in the Martian surface. The image has been white balanced and contrast-enhanced to make the hole clearer. Read our full story of Curiosity's first Mars drilling since 2016! — Chelsea Gohd
