NASA Supermassive-Black-Hole Gravity Discovery: "Confirms Einstein's Theory of Space-Time" Two X-ray space observatories, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and the European Space Agency's XMM-Newton , have teamed up to measure definitively, for the first time, the spin rate of a black hole with a mass 2 million times that of our sun that lies at the dust- and gas-filled heart of a galaxy called NGC 1365 (image above). Measuring the spin of a supermassive black hole is fundamental to understanding its past history and that of its host galaxy. The observations are a powerful test of Einstein's theory of general relativity, which says gravity can bend space-time, the fabric that shapes our universe, and the light that travels through it. The supermassive black hole is spinning almost as fast as Einstein's theory of gravity will allow.
The findings, which appear in a new study in the journal Nature, resolve a long-standing debate about similar measurements in other black holes and will lead to a better understanding of how black holes and galaxies evolve.

Modellbau. NASA Snaps the First 360-degree Image of the Sun - Technology News by ExtremeTech. A little more than four years ago, NASA launched a twin pair of spacecraft as part of their STEREO (Solar TErrestrial RElations Observatory) mission.
The crafts traveled in opposite directions along the Earth’s orbit en route to positions on opposite sides of the sun. This past Sunday the two crafts reached their respective destinations and—for the first time—captured a 360-degree view of our local celestial heavy. The space agency is now being fed a steady stream of images of the sun from opposite sides that they are able to combine into 3D models. The STEREO probes are specifically tuned to four wavelengths of extreme ultraviolet radiation which can be used to trace key aspects of solar activity such as solar flares, tsunamis, and magnetic filaments. “With data like these, we can fly around the sun to see what’s happening over the horizon—without ever leaving our desks,” comments STEREO program scientist Lika Guhathakurta from NASA headquarters.

NASA conducted a successful 500-second test firing of the J-2X rocket engine on Wednesday, Nov. 9, marking another important step in development of an upper stage for the heavy-lift Space Launch System (SLS).
SLS will carry the Orion spacecraft, its crew, cargo, equipment and science experiments to destinations in deep space. SLS will be safe, affordable and sustainable to continue America's journey of discovery from the unique vantage point of space. "The J-2X engine is critical to the development of the Space Launch System," Dan Dumbacher, NASA's deputy associate administrator for exploration systems development, said after the test at NASA's Stennis Space Center in Mississippi. "Today's test means NASA is moving closer to developing the rocket it needs if humans are to explore beyond low-Earth orbit. " Data from the test will be analyzed as operators prepare for additional engine firings. Planets. Planets: The planet count in our solar system has gone as high as 15 before new discoveries prompted a fine tuning of the definition of a planet.
The most recent change was in 2006 when scientists reclassified Pluto as a new kind of object - a dwarf planet. Dwarf Planets: This new class of worlds helps us categorize objects that orbit the Sun but aren't quite the same as the rocky planets and gas giants in our solar system. There could be hundreds more of these small worlds far out there waiting to be discovered. Moons: This count includes only the moons orbiting the eight planets in our solar system. Asteroids: New asteroids are discovered on an almost daily basis.
