Peering Through Titan's Haze
Washington DC (SPX) Dec 08, 2015
This composite image shows an infrared view of Saturn's moon Titan from NASA's Cassini spacecraft, acquired during the mission's "T-114" flyby on Nov. 13, 2015. The spacecraft's visual and infrared mapping spectrometer (VIMS) instrument made these observations, in which blue represents wavelengths centered at 1.3 microns, green represents 2.0 microns, and red represents 5.0 microns. A view at visible wavelengths (centered around 0.5 microns) would show only Titan's hazy atmosphere (as in PIA14909) ... read more

				Radio Shadow Reveals Tenuous Cosmic Gas Cloud Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered the most tenuous molecular gas ever observed. They detected the absorption of radio waves by gas clouds in f ... more		To Jupiter with JunoCam When NASA's Juno mission arrives at Jupiter on July 4, 2016, new views of the giant planet's swirling clouds will be sent back to Earth, courtesy of its color camera, called JunoCam. But unlik ... more

A new technique to gauge the distant Universe Scientists have developed a technique to use quasars - powerful sources driven by supermassive black holes at the centre of galaxies - to study the Universe's history and composition. To demonstrate ... more		ALMA spots monstrous baby galaxies cradled in dark matter Astronomers discovered a nest of monstrous baby galaxies 11.5 billion light-years away using the Atacama Large Millimeter/submillimeter Array (ALMA). The young galaxies seem to reside at the junctio ... more		US lawmaker warns of military 'misunderstanding' risk with China Spain approves 'total' arms embargo against Israel Khamenei says Iran 'won't yield' to pressure to abandon uranium enrichment		Student discovers stellar chamaeleon had astronomers fooled for years Astronomers have been mistakenly interpreting the dust in the environment of a famous star. A graduate student has discovered that astronomers have for years been mistakenly interpreting the d ... more
