Astrophysics Astrophysics People have gazed at the stars, given them names, and observed their changes for thousands of years. NASA joined the ancient pursuit of knowledge of our universe comparatively recently. Goals The science goals of Astrophysics are breathtaking: we seek to understand the universe and our place in it. We are starting to investigate the very moment of creation of the universe and are close to learning the full history of stars and galaxies. SCIENCE FICTION TECHNOLOGY TERMS The following items are found in science fiction literature as technologies useful in authoring a plausible setting for a sci-fi story: PROPULSION: Faster Than Light Drive (FTL) is required for stories about star based exploits. Twentieth century rocketry is limited to activities in the Solar System. At present spacecraft velocities, the nearest star would require voyages of thousands of years. At the speed of light, the nearest stars could be reached in decades of time. Several types of FTL systems are found in sci-fi literature.
How 1-Year Space Mission Affected Astronaut Twin Scott Kelly: Early Results Spending a year in space affected former NASA astronaut Scott Kelly's body in subtle but potentially significant ways, new research suggests. Kelly and cosmonaut Mikhail Kornienko flew the first-ever yearlong mission aboard the International Space Station (ISS), wrapping up the flight with a touchdown on the steppes of Kazakhstan last March. The goal of the project — which is ongoing, in the data-analysis phase — is to gauge the physiological and psychological impacts of long-duration spaceflight, to help prepare for crewed missions to Mars and other distant destinations. Part of this work involves Scott Kelly's identical twin brother Mark — a former NASA astronaut who flew on four space shuttle missions.
Nature Blows My Mind! The Flamboyant Sea Slug nicoboxethai/CC BY 2.0 Nudibranch, or what we usually call sea slugs, blow my mind. Ever since spotting one for myself during a tide pool trip about a year ago, I've been fascinated with these creatures. I think of them as the drag queens of the sea: flashy stand-outs that are always dressed to the nines. The one I found is a Hermissenda crassicornis -- the flashy little thing pictured below with bright pinkish-orange cerata waving like a feather boa and neon blue outlines around its tentacles.

Pixnary - Visual Vocabulary for CAT "Coleridge was evidently one of those people who abase themselves excessively in the hope of never having to hear their faults expressed on the lips of others." "What would possess anyone to take such blessings and abase them with dollar signs?" "Where the people are Catholic and submissive to the law of God, as declared and applied by the vicar of Christ and supreme pastor of the church, democracy may be a good form of government; but combined with Protestantism or infidelity in the people, its inevitable tendency is to lower the standard of morality, to enfeeble intellect, to abase character, and to retard civilization, as even our short American experience amply proves." "The human spirit is fashioned in the likeness of the Creator: it is improper to abase that spirit to some other component of the Creation."
Lushprojects.com - www.lushprojects.com - Circuit Simulator This electronic circuit simulator is highly interactive giving the feeling of playing with real components. It's very helpful for experimentation and visualization. Best of all, thanks to the power of HTML5, no plug-ins are required! The original implementation, in Java, belongs to Paul Falstad who kindly gave his permission for me to build this port. Click here to open the simulator in a full window. How to use this Science Mission Directorate Solar System, Sky Watching, Meteor Showers Earth will pass through a stream of debris from comet 2003 EH1 on January 3, 2017, producing a shower of meteors known as the Quadrantids. A three-year NASA field expedition to examine Earth’s coral reefs is now underway, giving scientists the opportunity to study reefs ecology and condition.
Nudibranch looks like a bunny of the sea It’s round, and fluffy and has wiggly little ears! Sort of. These little sea creatures, affectionately dubbed “sea bunnies” have recently become social media celebrities.
