Beyonce Knowles NASA

During Destiny’s Child’s hiatus, Beyoncé made her theatrical film debut with a role in the US box-office number-one Austin Powers in Goldmember (2002) and recorded her first solo album, Dangerously in Love (2003), which debuted at number one on the US Billboard 200 chart. It also featured the Billboard Hot 100 number-one singles “Crazy in Love” and “Baby Boy”. Following the disbandment of Destiny’s Child in 2006, she released her second solo album, B’Day, which contained the US number-one single “Irreplaceable” as well as the UK number-one singles “Déjà Vu” and “Beautiful Liar”. Beyoncé continued her acting career with starring roles in The Pink Panther (2006), Dreamgirls (2006), and Obsessed (2009). Her marriage to rapper Jay-Z and her portrayal of Etta James in Cadillac Records (2008) influenced her third album, I Am. . . Sasha Fierce (2008), which earned a record-setting six Grammy Awards in 2010. It spawned the UK number-one single “If I Were a Boy” and the US number-one single “Single Ladies (Put a Ring on It)”.



Vast regions of dark dunes also extend across Titan's exotic landscape, especially around its equatorial regions. Unlike Earth's sand, the "sand" that creates Titan's dunes is composed of dark grains of hydrocarbon that resemble coffee grounds. The tall linear dunes of this misty moisty moon-world appear to be quite similar to those seen in the desert of Namibia in Africa. Because Titan's surface is pockmarked by relatively few impact craters, its surface is considered to be quite young. Older surfaces display heavier cratering than more youthful surfaces, whose craters have been "erased" by resurfacing. This resurfacing is caused by processes that cover the scars left by old impacts as time goes by. Our own planet is similar to Titan in this respect. The craters of Earth are erased by the ongoing processes of flowing liquid (water on Earth), powerful winds, and the recycling of Earth's crust as a result of plate-tectonics. These processes also occur on Titan, but in modified forms. In particular, the shifting of the ground resulting from pressures coming from beneath (plate tectonics), also appear to be at work on this veiled moon-world. However, planetary scientists have not seen signs of plates on Titan that are analogous to those of our own planet. "The rectangular pattern of gravity anomalies was completely unexpected. Using the gradients in the gravity data to reveal the rectangular pattern of anomalies, we can now clearly and completely see structures that were only hinted at by surface observations," Dr. Jeffrey Andrews-Hanna explained in the October 1, 2014 NASA Press Release. Dr. Andrews-Hanna, a GRAIL co-investigator at the Colorado School of Mines in Golden, Colorado, is lead author of the paper. The scientists also ruled out the possibility that the mysterious features actually exist on Titan's surface in the form of frozen methane rain or icy lava erupted from cryovolcanoes. Such surface features would show a different chemical signature and would be visible for much longer periods of time than the bright features observed in this study. The bright features were visible from time spans of only 11 hours to five weeks.
