 This stunning mosaic of the sky around bright stars Antares (Alpha Scorpii) and Rho Ophiuchi reveals spectacular colors in a cosmic starscape. Near the top, Rho Ophiuchi and nearby stars are immersed in blue reflection nebulae - dust clouds that shine primarily by reflected starlight. Cool supergiant star Antares (lower left) is itself shedding the material that reflects the evolved star's yellowish hue. Characteristic of star forming regions, the telltale red emission from hydrogen gas also permeates the view along with dark, obscuring dust clouds seen in silhouette against the background stars and brighter nebulosities. About 500 light-years away, the Rho Ophiuchi star clouds, are well in front of the nearby globular star cluster M4, visible just below and right of center. The wide view spans about 6 degrees on the sky.

 In 1787, astronomer William Herschel discovered the Eskimo Nebula. From the ground, NGC 2392 resembles a person's head surrounded by a parka hood. In 2000, the Hubble Space Telescope imaged the Eskimo Nebula. From space, the nebula displays gas clouds so complex they are not fully understood. The Eskimo Nebula is clearly a planetary nebula, and the gas seen above composed the outer layers of a Sun-like star only 10,000 years ago. The inner filaments visible above are being ejected by strong wind of particles from the central star. The outer disk contains unusual light-year long orange filaments.

This bright galaxy is one of the most famous examples of an edge-on spiral galaxy, oriented perpendicularly to our line of sight so that we see right into its luminous disc. NGC 4565 has been nicknamed the Needle Galaxy because, when seen in full, it appears as a very narrow streak of light on the sky. It is amazing to see such beautiful detail in a galaxy 50 million light years from Earth both from the ground and in astonishing close ups by Hubble.

Mercury at Greatest Western Elongation 13 Jul 2014 @
02:31 UTC

Across much of the world Mercury will be well placed for observation in the dawn sky, shining brightly at mag -2.1.

Mercury never ventures far from the Sun in the sky since its orbit lies closer to the Sun than the Earth's. Mercury is said to be at greatest enlongation when it passes either of the two points along its orbit where it appears at greatest separation from the Sun.When is to the west of the Sun, it rises and sets a short time before the Sun, becoming visible shortly before sunrise.

Mercury reaches angular separation from the Sun  at a distance of 20.9° at greatest elongation. 

The altitude at which Mercury appears above the horizon at sunrise or sunset depends how steeply the line of the ecliptic is inclined to the horizon. If the plane of the ecliptic meet the horizon at a very shallow angle, Mercury will rise or set along a line which is almost parallel to the horizon, and a separation of 20° from the Sun along this line would correspond to a very low altitude in the sky.

Distance from Earth: 0.858 AU
Distance from Sun: 0.377 AU
Apparent Diameter : 7.8" 
Magnitued: -2.1
Elangation from Sun: 20°54'37"

I made this GIF animation based on the still images available in this March news release on changes in gullies on Mars (that I saw today related to a newer release) http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA17958

I cropped them out of their single mosaic release for this animation (since I couldn't see the originals alone.)

Third rock from the Sun
 
 Is this our Sun? Yes. Even on a normal day, our Sun is sizzling ball of seething hot gas. Unpredictably, regions of strong and tangled magnetic fields arise, causing sunspots and bright active regions. The Sun's surface bubbles as hot hydrogen gas streams along looping magnetic fields. These active regions channel gas along magnetic loops, usually falling back but sometimes escaping into the solar corona or out into space as the solar wind. Pictured above is our Sun in three colors of ultraviolet light. Since only active regions emit significant amounts of energetic ultraviolet light, most of the Sun appears dark. The colorful portions glow spectacularly, pinpointing the Sun's hottest and most violent regions. Although the Sun is constantly changing, the rate of visible light it emits has been relatively stable over the past five billion years, allowing life to emerge on Earth.

The European Space Agency's CHaracterising ExOPlanet Satellite (CHEOPS) is ready for construction. The spacecraft has gone from selection to implementation in less than 18 months and is on course to be ready to launch by December 2017.

MEDIA ADVISORY M14-117
Leading Space Experts to Discuss the Search for Life Beyond Earth
NASA Television will air a panel discussion of leading science and engineering experts on Monday, July 14, from 2 to 3:30 p.m. EDT, who will describe the scientific and technological roadmap that will lead to the discovery of potentially habitable worlds among the stars.
The public is invited to attend or view the event, which will take place in the Webb Auditorium at NASA Headquarters, 300 E Street SW in Washington. 
Space and ground observatories are cataloging and characterizing hundreds and what is expected to eventually be thousands of potentially habitable worlds in our galaxy. NASA space-based observatories are making unprecedented new discoveries. The agency’s next step, the James Webb Space Telescope (Webb telescope), will continue to help scientists rewrite scientific textbooks after its scheduled launch in 2018.
NASA Administrator Charles Bolden will provide opening comments.
Panel participants include:
-- Ellen Stofan, NASA’s chief scientist, NASA Headquarters, Washington
-- John Grunsfeld, astronaut and associate administrator, NASA's Science Mission Directorate in Washington
-- John Mather, Nobel Laureate and Senior Project Scientist for the Webb telescope at NASA’s Goddard Space Flight Center in Greenbelt, Maryland
-- Sara Seager, MacArthur Fellow and Professor of Planetary Science and Physics at the Massachusetts Institute of Technology, Cambridge
-- Dave Gallagher, director for Astronomy and Physics, NASA's Jet Propulsion Laboratory, Pasadena, California
-- Matt Mountain, director of the Space Telescope Science Institute in Baltimore and Telescope Scientist for the Webb telescope
Questions can be asked during the event by attendees or via Twitter using the hashtag #AskNASA.

Astronomers have calculated the ages of 22 Sun-like stars using a new technique, called gyrochronology, that measures how old a star is by checking its spin.

I made this animation tonight using regular online google maps from the same location roughly every 5 minutes, which shows that they update the clouds with REAL satellite images from today (although the images are reduced in detail from the originals to just the biggest brightest clouds.)  It also shows the day/night line passing over the Eastern United States, and you can see the real (archival) light pollution map.  The clouds even update on the night side.  If I had the energy to keep doing this for 24 hours, we could watch the brightest part of the Milky Way go by (because that's a real map of brightest Milky Way stars behind the Earth.)  If you'd like to try swinging the Earth around yourself, here's the location I was shooting this animation from
https://www.google.com/maps/@29.9530344,-74.2738171,22957317m/data=!3m1!1e3

Just grab the Earth, and see our galaxy swing by in the background, and the Sun too if you swing the Earth to the dark side.  Then zoom in with your roller on your mouse/device, and zoom in on regular google maps.  The best part about this is we don't need to download extra software to show others our location in the galaxy!
