4 Images of Io obtained at different infrared wavelengths (in microns, μm, or millionths of a meter) with the W. M. Keck Observatory's 10-meter Keck II telescope on Aug. 15, 2013 (a-c) and the Gemini North telescope on Aug. 29, 2013 (d). The bar on the right of each image indicates the intensity of the infrared emission. Note that emissions from the large volcanic outbursts on Aug. 15 at Rarog and Heno Paterae have substantially faded by Aug. 29. A second bright spot is visible to the north of the Rarog and Heno eruptions in c and to the west of the outburst in d. This hot spot was identified as Loki Patera, a lava lake that appeared to be particularly active at the same time. An even brighter outburst is seen to the lower right in panel (d), labeled C and is one of the most powerful outbursts ever seen on Io. De Kleer used the fortuitous detection of this outburst simultaneously at Gemini and the IRTF to show that the eruption temperature is likely much higher than typical eruption temperatures on Earth today, "indicative of a composition of the magma that on Earth only occurred in our planet s formative years," de Kleer said. Usually seen only on ~ years- here 3 eruptions in a couple of weeks. Figure 2. Images of Io taken in the near-infrared with adaptive optics at the Gemini North telescope tracking the evolution of the eruption as it decreased
5 in intensity over 12 days. Due to Io s rapid rotation, a different area of the surface is viewed on each night; the outburst is visible with diminishing brightness on August 29 & 30 and September 1, 3, & 10. Image credit: Katherine de Kleer/UC Berkeley/Gemini Observatory/AURA
6 GU Psc b is around 2,000 times the Earth-Sun distance from its star, a record among exoplanets. Given this distance, it takes approximately 80,000 Earth years for GU Psc b to make a complete orbit around its star! The researchers also took advantage of the large distance between the planet and its star to obtain images. By comparing images obtained in different wavelengths (colours) from the OMM and CFHT, they were able to correctly detect the planet. ~10 Jupiters GMOS and NIRI?
7 Astronomers have for the first time found strong evidence for a giant black hole in a Lilliputian galaxy. The finding suggests that supermassive black holes could be twice as numerous in the nearby Universe as previously estimated, with many of them hidden at the centres of small, seemingly nondescript galaxies known as ultra-compact dwarfs. And whereas supermassive black holes typically have about 0.5% of the mass of the stars that are concentrated in the centre of their galaxies, the black hole in M60-UCD1 is about 18% of the mass of the galaxy's stars, enabling the gravitational monster to wield a much greater influence over the galaxy s shape and structure. Recognizing the dominant role that some supermassive black holes have in the evolution of small galaxies is the most important result of the study, says astronomer Karl Gebhardt of the University of Texas at Austin.
