20 Sep 2017, 08:00 UTC Delving deep into the history of our cosmos, the Herschel Space Observatory scrutinised hundreds of thousands of star-forming galaxies, peering back in time to when the Universe was less than one billion years old. These observations probed the peak epoch of stellar production, about ten billion years ago, when galaxies were forming stars roughly ten times faster than their present counterparts.

Direct link What do we need to know to mine an asteroid?

19 Sep 2017, 05:00 UTC European Planetary Science Congress 2017 Press Notice Tuesday, 19th September What do we need to know to mine an asteroid? The mining of resources contained in asteroids, for use as propellant, building materials or in life-support systems, has the potential to revolutionise exploration of our Solar System. To make this concept a reality, we need to increase our knowledge of the very diverse population of accessible Near Earth Asteroids (NEA). Last year, dozens of the world’s leading asteroid scientists and asteroid mining entrepreneurs came together in Luxembourg to discuss key questions and identify scientific knowledge gaps. A White Paper outlining the results of that discussion, “Answers to Questions from the Asteroid Miners” will be presented at the European Planetary Science Congress (EPSC) 2017 in Riga on Tuesday 19th September by Dr JL Galache and Dr Amara Graps. “Asteroid mining is this incredible intersection of science, engineering, entrepreneurship and imagination,” says Galache of Aten Engineering. “The problem is, it’s also a classic example of a relatively young scientific field in that the more we find out about asteroids through missions like Hayabusa and Rosetta, the more we realise that we don’t know.” The aim of the Asteroid Science Intersections with In-Space ...

Direct link Nanosat fleet proposed for voyage to 300 asteroids

19 Sep 2017, 05:00 UTC European Planetary Science Congress 2017 Press Notice Tuesday, 19th September Nanosat fleet proposed for voyage to 300 asteroids A fleet of tiny spacecraft could visit over 300 asteroids in just over three years, according to a mission study led by the Finnish Meteorological Institute. The Asteroid Touring Nanosat Fleet concept comprises 50 spacecraft propelled by innovative electric solar wind sails (E-sails) and equipped with instruments to take images and collect spectroscopic data on the composition of the asteroids. Each nanosat would visit six or seven asteroids before returning to Earth to deliver the data. The concept will be presented by Dr Pekka Janhunen at the European Planetary Science Congress (EPSC) 2017 in Riga on Tuesday 19th September. “Asteroids are very diverse and, to date, we’ve only seen a small number at close range. To understand them better, we need to study a large number in situ. The only way to do this affordably is by using small spacecraft,” says Janhunen. In the mission scenario, the nanosats flyby their target asteroids at a range of around 1000 kilometres. Each nanosat carries a 4-centimetre telescope capable of imaging the surface of asteroids with a resolution of 100 metres or better. An infrared ...

Direct link Size matters in the detection of exoplanet atmospheres

19 Sep 2017, 05:00 UTC Size matters in the detection of exoplanet atmospheres A group-analysis of 30 exoplanets orbiting distant stars suggests that size, not mass, is a key factor in whether a planet’s atmosphere can be detected. The largest population-study of exoplanets to date successfully detected atmospheres around 16 ‘hot Jupiters’, and found that water vapour was present in every case. The work by a UCL-led team of European researchers has important implications for the comparison and classification of diverse exoplanets. The results will be presented by Angelos Tsiaras at the European Planetary Science Congress (EPSC) 2017 in Riga on Tuesday 19th September. “More than 3,000 exoplanets have been discovered but, so far, we’ve studied their atmospheres largely on an individual, case-by-case basis. Here, we’ve developed tools to assess the significance of atmospheric detections in catalogues of exoplanets,” said Angelos Tsiaras, the lead author of the study. “This kind of consistent study is essential for understanding the global population and potential classifications of these foreign worlds.” The researchers used archive data from the ESA/NASA Hubble Space Telescope’s Wide Field Camera 3 (WFC3) to retrieve spectral profiles of 30 exoplanets and analyse them for the characteristic fingerprints of gases that might be present. About half ...
