Lights from areas in the Gulf Coast states of Texas, Louisiana, Mississippi and Alabama, as well as some of the states that border them on the north, are visible, according to a NASA image description. Some lights appear to be from off-shore oil rigs in the Gulf of Mexico itself.

Hvar, Croatia, on Aug. 2, 2014. The island lies in the Adriatic sea. Kurtović writes in an email message to Space.com: "Croatian islands are less light polluted than mainland, but [the] town [of] Hvar is pretty popular among tourists, and thus more light polluted than some other places on Hvar island or other islands like Lastovo. [The photo] was taken while I was lying on the terrace of [a] soon-to-be one-hundred-year-old house. The palms are as old as the house."

at the bottom, and its blue-tinted companion SDSS J161330.18+510335 at the top. The two form a galactic pair named Zw I 136. The two galaxies interact, and possess disturbed shapes and extended soft haloes. At the right lies a galaxy with a shape perhaps more familiar to viewers, a side-on spiral.

line going diagonally across the center of the sun in this image. Filaments consist of clouds of cooler gas raised above the sun’s surface by magnetic forces. Normally they exhibit a great deal of unstability and break apart in days or even hours. This image was obtained in the 191 Angstrom wavelength of extreme ultraviolet light, and has been tinted red instead of the usual brown color.

stars orbiting their host galaxy. In the 1990s, the cluster first appeared to have a mystifyingly young age compared to other Milky Way globular clusers. However, since the early estimates, Hubble has provided new information showing IC 4499 has been around roughly the same amount of time as the Milky Way clusters, 12 billion years. Image released Aug. 4, 2014.

The Small and Large Magellanic Clouds, the closest galaxies to our galaxy, The Milky Way, glow in the sky at right. ALMA aims to observe the coldest and most ancient objects in the cosmos — known as the "cold universe." The array of antennas measures millimetre and submillimetre wavelength radiation, between infrared and radio waves in the electromagnetic spectrum. The array contains 66 configurable mobile antennas on the ALMA site to meet scientists' needs, making it the biggest astronomical experiment in existence. Image released Aug. 4, 2014.

in late winter only on south-facing slopes that have not received much direct sunlight. Ridges between gully alcoves receiving more light appear reddish and mostly free of frost. New gully activity is not readily detectible in this image. In some years, the frost (up to roughly 3.3 feet or 1 meter thick) triggers avalanches, although not in most years. The frost here consists of mostly carbon dioxide (dry ice), but also contains small amounts of water ice. Image released July 30, 2014.

just enough to show glimpses of the galactic central bulge, which contains no gas and where no star formation is occurring--none, in fact, for billions of years. In general, the bulge of a spiral galaxy consists of a quasi-spherical, amorphous ball of old stars. Image released July 2014.
