The Kuiper Belt is a vast disk of icy debris left over from our Sun's formation 4.6 billion years ago. Kuiper Belt objects (KBOs) are a unique class of solar-system body that has never been visited by interplanetary spacecraft. They contain well-preserved clues to the origin of our solar system. NASA's New Horizons probe will fly by Pluto in mid-2015 and then continue across the Kuiper Belt on its way toward interstellar space. The Hubble Space Telescope was used to do a deep sky survey to identify KBOs that the New Horizons spacecraft could potentially visit on its outbound trajectory. The deep sky survey was successful, and Hubble found targetable KBOs for New Horizons.
The net energy consumption of the US has held fairly steady for nearly 20 years. Over the past decade, however, there's been a large increase in production of energy within the US. As a result, the US government's energy figures for the first half of this year show that the differences between production and consumption have dropped to the lowest level in 29 years. This represents a net drop in energy imports by 17 percent compared to the same period a year earlier.
According to the Energy Information Agency, the boost in energy production came from a variety of sources. Natural gas was the largest, accounting for just over half of the annual increase. Coal accounted for another quarter, renewable energy for 12 percent, and petroleum for eight. The EIA also notes that energy use this year was unusually high due to the intense cold that hit most of the nation in the first few months of 2014.
The vast majority of the country's imports come in the form of petroleum products and crude oil. These imports have been decreasing as new sources of oil are tapped and automotive efficiency standards are tightening. Refined petroleum products remain the largest US energy export; smaller quantities of coal and natural gas are also shipped overseas.

ESA and its Rosetta mission partners are inviting you to suggest a name for the site where lander Philae will touch down on Comet 67P/Churyumov–Gerasimenko on 12 November.
This Rosetta spacecraft selfie was snapped on October 7th. At the time the spacecraft was about 472 million kilometers from planet Earth, but only 16 kilometers from the surface of comet 67P/Churyumov-Gerasimenko. Looming beyond the spacecraft near the top of the frame, dust and gas stream away from the comet's curious double-lobed nucleus and bright sunlight glints off one of Rosetta's 14 meter long solar arrays. In fact, two exposures, one short and one long, were combined to record the dramatic high contrast scene using the CIVA camera system on Rosetta's still-attached Philae lander. Its chosen primary landing site is visible on the smaller lobe of the nucleus. This is the last image anticipated from Philae's cameras before the lander separates from Rosetta on November 12. Shortly after separation Philae will take another image looking back toward the orbiter, and begin its descent to the nucleus of the comet.
Members of the media are invited to attend events being held by ESA and the German and French space agencies on the occasion of the first ever attempt at landing on a comet.
