September 14, 2017 – Astronomers have discovered that the well-studied exoplanet WASP-12b reflects almost no light, making it appear essentially pitch black. This discovery sheds new light on the atmospheric composition of the planet and also refutes previous hypotheses about WASP-12b’s atmosphere. The results are also in stark contrast to observations of another similarly sized exoplanet. Read More

The Big Questions About Saturn That Doomed Cassini Mission May Yet Answer
Source: Nature

On 15 September at 4:55 a.m. California time, hundreds of scientists will watch their life’s work go up in flames as the Cassini spacecraft burns up in Saturn’s atmosphere. NASA is deliberately crashing the probe — now short on fuel — to avoid an accidental collision that could contaminate the planet’s moons, such as Titan, known for its Earth-like prebiotic chemistry, or Enceladus, home to a buried ocean. But as it plunges to its death, the probe will transmit a last burst of data that will keep research teams busy for years to come. Many discoveries about Saturn’s moons, rings and interior are likely to emerge in the coming months, thanks to data gathered by Cassini’s instruments up until the bitter end.

The National Radio Astronomy Observatory (NRAO) and Associated Universities, Inc. (AUI) are launching a new initiative to design a next-generation radio telescope with scientific capabilities far beyond those provided by any existing or currently proposed observatory. Building on the success of one of the National Science Foundation’s (NSF) flagship observatories, the Karl G. Jansky Very Large Array (VLA), NRAO and AUI are beginning a two-year project to explore the science opportunities, design concepts, and technologies needed to construct a new class of radio telescope.

Physicists Offer Explanation For Diverse Galaxy Rotations

Two galaxies that appear at first glance to be very similar and effectively identical can have inner regions rotating at very different rates – the galactic analog of twins with different lifestyles. A team of physicists, led by Hai-Bo Yu of the University of California, Riverside, has found a simple and viable explanation for this diversity.

In recent years, composite replicated mirrors have gained increasing attention over traditional polished glass mirrors because of their potential for significant improvements in manufacturing lead-time, aerial density, and lower cost, and for their tailorable mechanical and thermal properties. Working to advance the technology, scientists and engineers in Aerospace’s Materials Science Department, led by Dr. Rafael Zaldivar, have been experimenting with a series of unique in-house processing protocols, overcoming many critical issues with composite mirrors.

NASA’s Robotic ‘Sniffer’ Confirms Space Station Leak, Repair

In recent operations on the International Space Station, robotic operators were twice able to test and confirm the ability of the Robotic External Leak Locator (RELL) to “smell” in space. Using the RELL instruments, operators successfully located a small leak from the station’s ammonia coolant loop, and confirmed that it was not a safety concern. Later they were able to return and more precisely characterize the leak. This valuable data helped station operators vent and isolate the leaking line from the coolant loop and successfully stop the leak.

The Cassini spacecraft will crash into Saturn on Friday, a dramatic finale to a mission that revolutionized our understanding of the ringed planet. Perhaps its most tantalizing reports were of Saturn’s moons: Titan, which hosts a liquid methane sea, and Enceladus, where geysers of water shoot up from the surface. Both are now considered among the top prospects for the search for alien life.
