Starry skies are a vanishing treasure because light pollution is washing away our view of the cosmos. It not only threatens astronomy, it disrupts wildlife, and affects human health. The yellow glows over cities and towns — seen so clearly from space — are testament to the billions spent in wasted energy from lighting up the sky.

To help raise public awareness of some of the issues pertaining to light pollution, Loch Ness Productions in collaboration with the International Dark-Sky Association has created a 6.5-minute "public service announcement" called Losing the Dark. It introduces and illustrates some of the issues regarding light pollution, and suggests three simple actions people can take to help mitigate it.
Losing the Dark was initially created in fulldome video format for digital planetarium use. It also has been made as a conventional flat screen video, for use in classrooms, kiosks, museum theaters, and advocate multimedia presentations. Classic planetarium theaters without fulldome capability can show this version using their traditional video projectors.

Fresh water is pivotal to humans. We rely on it for food production, as energy resource and much more. Knowledge about the water cycle is crucial also for coastal communities and marine industry; just to mention a few more examples of how important chasing water is.
Learn how we use satellite altimetry to measure both sea surface height and water in other elements of the water cycle. Satellite altimetry veteran Dr. Ole Andersen from Danish National Space Center and pioneer Professor Philippa Berry from De Montfort University in the UK tells you both about the technique and how it is currently being used.
Carolyn Collins Petersen is Visiting Eta CarinaeIn this episode of The Astronomer's Universe we re-visit a region of space that has fascinated astronomers for decades: the Carinae Nebula and the soon-to-explode luminious blue variable star called Eta Carinae. This star, which is really a stellar pair, has been brightening and dimming, puffing out huge amounts of gas and dust, and giving astronomers new insight into the deaths of very massive stars. Learn the latest thinking about when this star might become a hypernova!
