"Uranus is a geometric nightmare," said Carol Paty, the Georgia Tech associate professor who co-authored the study. "The magnetic field tumbles very fast, like a child cartwheeling down a hill head over heels. When the magnetized solar wind meets this tumbling field in the right way, it can reconnect and Uranus' magnetosphere goes from open to closed to open on a daily basis."

ESA's Gaia Space Telescope Mimics the Human Brain --"Reveals Some of the Most Obscure Regions of the Milky Way" (VIDEO)

Our galactic home, the Milky Way, houses more than a hundred billion stars, all kept together by gravity. Most are located in a flattened structure – the galactic disc – with a bulge at its center, while the remaining stars are distributed in a wider spherical halo extending out to about 650 000 light-years from the center. With the help of software that mimics a human brain, ESA's Gaia satellite spotted six stars zipping at high speed from the center of our galaxy to its outskirts. This could provide key information about some of the most obscure regions of the Milky Way.

Milky Way's 'Dark-Matter' Anomaly --"Explains Why Our Galaxy Appears to be Special"

 

 

 

Milky-Way-s-Dark-Matter-Disk-Can-t-Be-Found-2


In the enchanting night sky, with myriad galaxies and stars, what we see is only about 20% of all the matter in the Universe. The remaining is in the form of a non-luminous and exotic form of matter that we know little about. This so-called dark matter has been the object of intense scientific exploration in the last few decades. According to many popular theories, dark matter particles annihilate at the same rate in both small and large astronomical bodies and at all times in the Universe.

NASA's Cassini Mission Grand Finale at Saturn --Join Live At NASA's Jet Propulsion Lab (Today's 'Galaxy' Stream)

During its journey, Cassini has made many discoveries, including a global ocean with hydrothermal activity within Saturn's moon Enceladus, and vast seas of liquid methane on the planet's largest moon, Titan. Cassini began the final, dramatic phase of its mission, called the Grand Finale, on April 26, with the first of planned 22 dives between Saturn and its rings. The finale orbits bring the spacecraft closer to Saturn than ever before, providing stunning, high-resolution images and new insights into the planet's interior structure and the origins of the rings. During its final plunge into Saturn, Cassini will send data about the atmosphere's composition until its signal is lost.

The Milky Way --"Could Harbor a Spacetime Tunnel the Size of the Galaxy Itself Hiding in Dark Matter" (Today's Most Popular)

Astrophysicists from the International School for Advanced Studies (SISSA) in Trieste, Italy, speculated in a 2015 study that wormholes, predicted by Einstein in his theory of General Relativity as areas where space and time are bent to manipulate the distance, are possible, and could be hiding within dark matter inside the Milky Way. But, It would take a huge mass to produce the manipulation of spacetime, and no evidence of their existence has ever been found. Based on their theory,  our galaxy could be a huge wormhole (or space-time tunnel) and, if that were true, it would be "stable and navigable."

Mystery of Sun's Erupting Plasma Jets Solved --"Reach Heights of 6,000 Miles"

 

751917main_highres4_full_2

 

At any given moment, as many as 10 million wild jets of solar material burst from the sun's surface. They erupt as fast as 60 miles per second, and can reach lengths of 6,000 miles before collapsing. These are spicules, and despite their grass-like abundance, scientists didn't understand how they form. Now, for the first time, a computer simulation -- so detailed it took a full year to run -- shows how spicules form, helping scientists understand how spicules can break free of the sun's surface and surge upward so quickly.

The Curious Case of the Warped Kuiper Belt --"Is There an Earth-Sized Planet Far Beyond Pluto?"

The plane of the solar system is warped in the outer reaches of the Kuiper Belt, signaling the presence of an unknown Mars-to-Earth-mass planetary object far beyond Pluto, according to new research from the University of Arizona. An unknown, unseen "planetary mass object" may lurk in the outer reaches of our solar system, according to new research on the orbits of minor planets. This object would be different from -- and much closer than -- the so-called Planet Nine, a planet whose existence yet awaits confirmation.

NASA --Artificial Intelligence is Changing How We Explore Mars & Beyond

 

Mars-rover


A glimpse of how we'll explore the cosmos in the future is here: A.I. software on NASA's Curiosity Mars rover has helped it zap dozens of laser targets on the Red Planet this past year, becoming a frequent science tool when the ground team was out of contact with the spacecraft. This same software has proven useful enough that it's already scheduled for NASA's upcoming mission, Mars 2020. Adding intelligence to robotic probes could enable probes sent to targets as far away Proxima b in the Alpha Centauri star system. Many of the world's leading astrophysicists believe that our first discovery of advanced alien civilizations will be in the form of machine AI, not biological.
