NATIONAL GEOGRAPHIC'S BEST SPACE PICTURES THIS WEEK XV


New Picture 498
Best Space Pictures: A Hurricane Simmers, the Milky Way Glimmers, and a New Rocket Is in the Works

National Geographic News, 4 July 2014.

A satellite spies a reservoir, a hurricane portrait is snapped, and part of a new rocket passes design review in this week's space gallery.

1. Purple Haze

New Picture 492

A spiral galaxy shines in blues, purples, and reds in this composite image of NGC 4258 released July 2. The various colours denote X-rays (blue), radio waves (purple), visible light (blue and yellow), and infrared light (red) blasting from this cosmic swirl.

NGC 4258 is also famous for two of its arms, which are not in the same plane as the rest of the galaxy. Instead, they intersect it. Researchers think they're formed when the shock waves produced by a supermassive black hole heat huge clouds of gas that bubble up from the galaxy.

2. Arthur

New Picture 493

A crew member on board the International Space Station snapped an image of a developing hurricane, named Arthur, off the eastern U.S. on July 2.

3. Closer to Flight

New Picture 494

NASA is one step closer to sending astronauts back into space. The dome above, one of the components of NASA's new rocket - the Space Launch System - passed a critical design review July 1. This means that parts of the rocket are ready to go into production.

4. Cosmic Lint

New Picture 495

NASA is sending the Hubble Space Telescope to search for suitable targets for a flyby of the New Horizons spacecraft in fall 2015. New Horizons will survey the surface and atmosphere of the dwarf planet Pluto and, hopefully, some objects (circled in the photographs) in the Kuiper Belt - a disk-shaped region of icy bodies beyond Neptune's orbit. Pluto is one of the better known objects in the belt.

5. Desert Oasis

New Picture 496

A Landsat 8 image, released July 1, shows a splash of turquoise that is the Hanhowuz Reservoir, surrounded by the Garagum Desert in Turkmenistan. The Garagum Canal snakes into the upper right corner of the reservoir.

Tiny plants called phytoplankton and fish, including catfish and Arab barbel, thrive in the reservoir's warm waters.

6. Galaxy at Night

New Picture 497

The Milky Way galaxy hangs in the night sky in an image submitted to Your Shot on June 26. The galaxy, which includes our solar system, stretches above the desert in An Nūmānīyah, Al Qasim, Saudi Arabia.
