ESA Top News 10 Jun 2019, 08:30 UTC The iconic appearance of a spiral galaxy is exemplified here in the form of the stunning NGC 2903, imaged by the NASA/ESA Hubble Space Telescope. It shows off whirling, pinwheeling arms with scatterings of sparkling stars, glowing bursts of gas, and dark, weaving lanes of cosmic dust.
NASA's Goddard Space Flight Center 7 Jun 2019, 13:30 UTC This striking image was taken by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 (WFC3), a powerful instrument installed on the telescope in 2009. WFC3 is responsible for many of Hubble’s most breathtaking and iconic photographs.
NASA's Jet Propulsion Laboratory News and Features 6 Jun 2019, 17:06 UTC NASA's Mars Helicopter flight demonstration project has passed a number of key tests with flying colors. In 2021, the small, autonomous helicopter will be the first vehicle in history to attempt to establish the viability of heavier-than-air vehicles flying on another planet.
ESA Space Science 6 Jun 2019, 13:00 UTC ESA’s Planck satellite has found no new evidence for the puzzling cosmic anomalies that appeared in its temperature map of the Universe. The latest study does not rule out the potential relevance of the anomalies but they do mean astronomers must work even harder to understand the origin of these puzzling features.
National Radio Astronomy Observatory (NRAO) 5 Jun 2019, 17:00 UTC ** Summary: New ALMA observations reveal a never-before-seen disk of cool, interstellar gas wrapped around the supermassive black holeSupermassive Black HoleA black hole that has a million or as much as a billion solar masses. These large black holes lurk at the centers of most galaxies. at the center of the Milky Way. This nebulous disk gives astronomers new insights into the workings of accretion Accretion diskA disk of gas that accumulates around a center of gravitational attraction, such as a white dwarf, a neutron star, or a black hole. As the gas spirals in, it becomes hot and emits energy at a variety of wavelengths, including X-ray and radio waves. : the siphoning of material onto the surface of a black hole. The results are published in the journal Nature. **Through decades of study, astronomers have developed a clearer picture of the chaotic and crowded neighborhood surrounding the supermassive black hole at the center of the Milky Way. Our galactic center is approximately 26,000 light-years from Earth and the supermassive black hole there, known as Sagittarius A* (A “star”), is 4 million times the mass of our Sun.We now know that this region is brimming with roving stars, interstellar ...
