One of the biggest mysteries in modern physics may have just been solved. The scientific community is abuzz with rumors that
physicists have finally detected gravitational waves, fluctuations in
the curvature of space-time that move at the speed of light throughout
the galaxy. Noted physicist Albert Einstein first predicted them in
1916, theorizing they might explain how mass affects the very fabric of
space-time. The discovery of the gravitational waves would be one of the biggest discoveries in physics in history
Over his tenure, President Obama has now invested $147 billion in America’s space program. Our elected leaders, on a bipartisan basis, have chosen to make this investment in our Agency, because they believe in our Journey to Mars and recognize that investments in NASA’s present are investments in America’s future.
Because the State of our NASA is strong, President Obama is recommending a $19 billion budget for the next year to carry out our ambitious exploration and scientific discovery plans. Here are the areas in which we’ll continue to invest:
We’re developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s. Mars is a rich destination for scientific discovery and robotic and human exploration as we expand our presence into the solar system. Its formation and evolution are comparable to Earth, helping us learn more about our own planet’s history and future.

Earth Right Now
We use the vantage point of space to increase our understanding of our home planet, improve lives and safeguard our future. Our Earth science work also makes a difference in people’s lives around the world every day.
Technology Drives Exploration
Sustained investments in our technology advance space exploration, science and aeronautics capabilities. We seek to improve our ability to access and travel through space; land more mass in more locations throughout our solar system; live and work in deep space and on planetary bodies; build next generation air vehicles, and transform the ability to observe the universe and answer profound questions in Earth and space sciences.
Thanks to advancements in aeronautics developed by NASA, today’s aviation industry is better equipped than ever to safely and efficiently transport all those passengers to their destinations.
The President’s FY 2017 budget provides $790 million to our Aeronautics Research Mission Directorate. This investment will accelerate aviation energy efficiency, advance propulsion system transformation and enable major improvements in aviation safety and mobility. The future of flight will: utilize greener energy, be half as loud, use half the fuel and will create quieter sonic booms.
State of NASA Social
Today, we have opened our doors and invited social media followers and news media to an in-person event, at one of our 10 field centers. Guests will go on a tour and see highlights of the work we’re doing. You can follow along digitally on Twitter: https://twitter.com/NASASocial/lists/state-of-nasa-all1.
Geminids of the South : Earth’s annual Geminid meteor shower did not disappoint, peaking before dawn on December 14 as our fair planet plowed through dust from active asteroid 3200 Phaethon. Captured in this southern hemisphere nightscape the meteors stream away from the shower’s radiant in Gemini. To create the image, many individual frames recording meteor streaks were taken over period of 5 hours. In the final composite they were selected and registered against the starry sky above the twin 6.5 meter Magellan telescopes of Carnegie Las Campanas Observatory in Chile. Rigel in Orion, and Sirius shine brightly as the Milky Way stretches toward the zenith. Near Castor and Pollux the twin stars of Gemini, the meteor shower’s radiant is low, close to the horizon. The radiant effect is due to perspective as the parallel meteor tracks appear to converge in the distance. Gemini’s meteors enter Earth’s atmosphere traveling at about 22 kilometers per second. via NASA
[GLIESE 504 B], [59 VIRGINIS] what it do end vs toc vs noah :: Nebula 16 we still gonna get back to the regular solar system narrative joints in a minute, but we wanted to come through with this first, you feel me?? just on some different shit right quick. had somethin else in us right now. AY THO CHECK IT nebula 17 comin thru real quick in the meantime, if you wanna get caught up with THAT whole weird planetary personification narrative, u can either download [NEBULA ULTRA] for free which collects all installments of it in a huge bundled Thing along with a lot of neat art we all did, or you can just click all these things:
Most galaxies possess a majestic spiral or elliptical structure. About a quarter of galaxies, though, defy such conventional, rounded aesthetics, instead sporting a messy, indefinable shape. Known as irregular galaxies, this group includes NGC 5408, the galaxy that has been snapped here by the NASA/ESA Hubble Space Telescope.
English polymath John Herschel recorded the existence of NGC 5408 in June 1834. Astronomers had long mistaken NGC 5408 for a planetary nebula, an expelled cloud of material from an aging star. Instead, bucking labels, NGC 5408 turned out to be an entire galaxy, located about 16 million light-years from Earth in the constellation of Centaurus(The Centaur).
In yet another sign of NGC 5408 breaking convention, the galaxy is associated with an object known as an ultraluminous X-ray source, dubbed NGC 5408 X-1, one of the best studied of its class. These rare objects beam out prodigious amounts of energetic X-rays. Astrophysicists believe these sources to be strong candidates for intermediate-mass black holes.
Despite being just 250 million light years from Earth—very close in astronomical terms—the new galaxies had been hidden from view until now by our own galaxy, the Milky Way.
Using CSIRO’s Parkes radio telescope equipped with an innovative receiver, an international team of scientists were able to see through the stars and dust of the Milky Way, into a previously unexplored region of space.
The discovery may help to explain the Great Attractor region, which appears to be drawing the Milky Way and hundreds of thousands of other galaxies towards it with a gravitational force equivalent to a million billion Suns.
Lead author Professor Lister Staveley-Smith, from The University of Western Australia node of the International Centre for Radio Astronomy Research (ICRAR), said the team found 883 galaxies, a third of which had never been seen before.
