Unit Telescopes of the VLT loom large at the right. At left stand the smaller Auxiliary Telescopes, with the large and small Magellanic Clouds above them. ESO Photo Ambassador Gabriel Brammer captured the scene with several shots taken at sunset and also later at night, then combined them together, showing the passage of time. Image released July 21, 2014.

spherical structures that orbit the centers of their galaxies like satellites. NGC 121, discovered in 1835 by English astronomer John Herschel, exists in the Small Magellanic Cloud (SMC), one of our neighboring galaxies. NGC 121 measures around 10 billion years old, making it the oldest cluster in its galaxy. The other globular clusters of the SMC have an age of 8 billion years old or younger. The reason for the age discrepancy has not been discovered yet.

mounted on the MPG/ESO 2.2-meter telescope located at the La Silla Observatory, Chile. This image represents one of five sky areas covered by the COMBO-17 survey (Classifying Objects by Medium-Band Observations in 17 filters), searching for cosmic objects in a relatively narrow area of the southern hemisphere's sky. The survey has already uncovered thousands of previously unknown deep sky objects, including over 25,000 galaxies, tens of thousands of stars and quasars heretofore undiscovered. In this photo, some of the most distant light comes from galaxies whose light travelled for nine or ten billion years before arriving on Earth. Image released July 14, 2014.

These deep-sky objects possess very bright, luminous centers comparable to that of our galaxy, the Milky Way. Hubble Space Telescope obtained the image using a combination of ultraviolet, visible, and infrared light. NGC 1433 makes up part of a survey of 50 nearby galaxies known as the Legacy ExtraGalactic UV Survey (LEGUS). Image released July 7, 2014.

The Antares will blast off with the Cygnus cargo craft carrying over 3,000 pounds (1360 kg) of supplies for the International Space Station, including science experiments, hardware, parts, and provisions. The Orbital-2 mission represents Orbital Sciences' second contracted cargo delivery flight to the space station for NASA, scheduled for July 11, 2014.

data from one orbit of the spacecraft, combined with lower-resolution color data taken during a different orbit. The blue-white terrains point out the presence of relatively pure water ice. The reddish areas contain water ice mingled with hydrated salts, perhaps magnesium sulfate or sulfuric acid. The reddish material notably appears in the broad band in the center of the image, also in some of the narrower bands, ridges, and disrupted chaos-type features. Possibly these surface features communicated with a global subsurface ocean layer some time during or after their formation. Galileo spacecraft obtained the grayscale images on November 6, 1997, and the lower-resolution color data in 1998. Image released July 8, 2014.

a water channel at NASA's Ames Research Center in Moffett Field, California.
In anticipation of this year’s (FIFA) 2014 World Cup tournament, NASA engineers used the opportunity to demonstrate concepts of aerodynamics. Here, green dye shows how water flows around a scale model of a traditional soccer ball. Pink dye injected separately behind the ball shows the position of a low-pressure zone trailing the ball.
Players during the previous World Cup in 2004, complained that the ball, the Jabulani, moved erratically in flight. This year’s new ball design, the Brazuca, developed by Adidas, features a distinctive six-panel design. In tests, the new ball compared favorably to a traditional 32-panel soccer ball.
“The players should be happier with the new ball,” said Rabi Mehta, chief of the Experimental Aero-Physics Branch at NASA's Ames Research Center. “It is more stable in flight and will handle more like a traditional 32-panel ball.”

I worked out the positioning using an iPhone app called PhotoPills, and then set up for the shoot. I was 1.8 km (1.12 miles) away from my friend on the hill, and as soon as I saw the moon beginning to rise behind her, I started shooting.” Image obtained June 13, 2014, in New Zealand.

He mentions in an email message to Space.com that he tried to include the foreground, featuring surrounding sand dunes and a pond that recently filled with water from flash floods. Light pollution from Panama City beach about 20 miles away fills the background.
