The arrangement of the spiral arms in the galaxy Messier 63, seen here in an image from the NASA/ESA Hubble Space Telescope, recall the pattern at the center of a sunflower. So the nickname for this cosmic object -- the Sunflower Galaxy -- is no coincidence. Discovered by Pierre Mechain in 1779, the galaxy later made it as the 63rd entry into fellow French astronomer Charles Messier's famous catalogue, published in 1781. The two astronomers spotted the Sunflower Galaxy's glow in the small, northern constellation Canes Venatici (the Hunting Dogs). We now know this galaxy is about 27 million light-years away and belongs to the M51 Group -- a group of galaxies, named after its brightest member, Messier 51, another spiral-shaped galaxy dubbed the Whirlpool Galaxy. Galactic arms, sunflowers and whirlpools are only a few examples of nature's apparent preference for spirals. For galaxies like Messier 63 the winding arms shine bright because of the presence of recently formed, blue-white giant stars and clusters, readily seen in this Hubble image.

What is fascinating about Pluto is how young its surface is. We can see some canyons, planes, and mountains in this image - which is an indication of a young surface. This image of Pluto was taken when the New Horizons spacecraft was only 280,000 miles away from the surface. In the image you can see features as small as 1.4 miles! Four images from New Horizons’ Long Range Reconnaissance Imager (LORRI) were combined with color data from the Ralph instrument to create this enhanced color global view.

Our InSight mission will place a fixed science outpost on Mars to study its deep interior. Findings and research from this project will address one of the most fundamental questions we have about planetary and solar system science – How in the world did these rocky planets form?
By investigating the interior structure and processes of Mars, the InSight mission will gain a better understanding of the evolutionary formation of planets, including Earth.
InSight will record Mars’ vital signs to learn more about the planet, including:
Seismic Activity:
A seismometer will be used to record the seismic activity on Mars. This will give us information on the crust, mantel and core; and the relationship between them.
Temperature:
A heat flow probe will be used to take Mars’ temperature and determine the change over the course of a full Martian year.
Reflexes:
By looking at how the rotation of Mars wobbles, we will better understand what the core size may be and its composition.
Launch for the InSight mission is scheduled for March 2016, and even though you can’t physically travel with the lander, you can send your name to the Red Planet onboard. Make sure to submit your name before Sept. 8!

Want to take a relaxing interstellar vacation? Consider visiting Kepler-16b, a world in a binary star system. In fact Kepler-16b is the first discovered circumbinary planet. It was detected in a wide 229 day orbit around a close pair of cool, low-mass stars some 200 light-years away. The parent stars eclipse one another in their orbits, observed as a dimming of starlight. But Kepler-16b itself was discovered by following the additional very slight dimming produced during its transits. Like sci-fi planet Tatooine of Star Wars fame, two suns would set over its horizon. Still, Kepler 16b is probably not a Tatooine-like terrestrial desert world. Instead, Kepler 16b is thought to be a cold, uninhabitable planet with about the mass of Saturn and a gaseous surface ... so plan to dress accordingly. Or, choose another Visions of the Future vacation destination. For image credit and copyright guidance, please visit the image websitehttp://antwrp.gsfc.nasa.gov/apod/ap160220.html
We have been expecting you Mr Handle......
Astronaut Kate Rubins has conducted out of this world research aboard Earth’s only orbiting laboratory. During her time aboard the International Space Station, she became the first person to sequence DNA in space. On Tuesday, she’ll be live on Facebook with National Institute of Health director Francis Collins, who led the effort to map the human genome. You can submit questions for Kate using the hashtag #SpaceChat on Twitter, or during the live event. Here’s a primer on the science this PhD astronaut has been conducting to help inspire your questions:
Kate has a background in genomics (a branch of molecular genetics that deals with the study of genomes,specifically the identification and sequencing of their constituent genes and the application of this knowledge in medicine, pharmacy,agriculture, and other fields). When she began her tenure on the station, zero base pairs of DNA had been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth base of DNA aboard the orbital platform.
“I [have a] genomics background, [so] I get really excited about that kind of stuff,” Rubins said in a downlink shortly after reaching the one billion base pairs sequenced goal.

+NASA AMA: We just sequenced DNA in space for the first time. Ask us anything!
We’re not doing this alone. Just like the DNA sequencing was a collaborative project with industry, so is the Eli Lilly Hard to Wet Surfaces investigation, which is a partnership between CASIS and Eli Lilly Co. In this experiment aboard the station, astronauts will study how certain materials used in the pharmaceutical industry dissolve in water while in microgravity. Results from this investigation could help improve the design of tablets that dissolve in the body to deliver drugs, thereby improving drug design for medicines used in space and on Earth. Learn more about what we and our partners are doing:

With our colleagues at the Stanford University School of Medicine, we’re also investigating the effects of spaceflight on stem cell-derived heart cells, specifically how heart muscle tissue, contracts, grows and changes in microgravity and how those changes vary between subjects. Understanding how heart muscle cells change in space improves efforts for studying disease, screening drugs and conducting cell replacement therapy for future space missions. Learn more:

Kate and her crew mates have also worked on the combustion experiments.
Kate has also worked on the Bigelow Expandable Activity Module (BEAM), an experimental expandable capsule that docks with the station. As we work on our Journey to Mars, future space habitats are a necessity. BEAM, designed for Mars or other destinations, is a lightweight and relatively simple to construct solution. Kate has recently examined BEAM, currently attached to the station, to take measurements and install sensors.
Kate recently performed a harvest of the Plant RNA Regulation experiment, by removing seed cassettes and stowing them in cold stowage.
The Plant RNA Regulation investigation studies the first steps of gene expression involved in development of roots and shoots. Scientists expect to find new molecules that play a role in how plants adapt and respond to the microgravity environment of space, which provides new insight into growing plants for food and oxygen supplies on long-duration missions.

NASA Astronaut Kate Rubins is participating in several investigations examining changes in her body as a result of living in space. Some of these changes are similar to issues experienced by our elderly on Earth; for example, bone loss (osteoporosis), cardiovascular deconditioning, immune dysfunction, and muscle atrophy. Understanding these changes and how to prevent them in astronauts off the Earth may help improve health for all of us on the Earth. In additional, the crew aboard station is also working on more generalized studies of aging.
