19 de julho de 2017 -Mountain View, CA e Meyreuil, França: o Instituto SETI e a startup francesa Unistellar, anunciaram hoje uma parceria para comercializar um novo telescópio que promete oferecer uma visão incomparável do cosmos aos astrônomos amadores e oferecer a oportunidade de contribuir diretamente para ciência de ponta.
O novo eVscope™ da Unistellar aproveita a tecnologia de imagem “Enhanced Vision” e agora oferece três recursos únicos nunca antes oferecidos em um instrumento compacto de mercado de massa graças a esta parceria:
O Enhanced Vision produz imagens extremamente nitidas e detalhadas de objetos astronômicos até mesmo fracos, acumulando a luz e projetando-a na ocular do telescópio. A tecnologia Enhanced Vision imita a capacidade de coleta de luz de telescópios de refletor significativamente maiores, oferecendo visões sem precedentes de objetos do céu noturno anteriormente inacessíveis aos astrônomos amadores.

SETI Institute y organización francesa Unistellar, anunciaron una asociación para comercializar un nuevo telescopio que promete entregar imágenes sin paralelo del cosmo a los astrónomos amateurs y proporcionar la oportunidad de contribuir de forma directa a ciencia de punta.
Nuevo eVscope™ de Unistelar eleva la tecnología de imagen “visión mejorada” y proporciona tres características únicas nunca antes incluidas en instrumentos compactos para el mercado masivo, gracias a esta asociación.
July 19 2017 -Mountain View, CA & Meyreuil, France: The SETI Institute and French startup Unistellar, announced a partnership today to commercialize a new telescope that promises to deliver an unparalleled view of the cosmos to amateur astronomers, and provide the opportunity to contribute directly to cutting-edge science.
Unistellar’s new eVscope™ leverages “Enhanced Vision” imaging technology and now provides three unique features never before offered in a compact mass-market instrument thanks to this partnership:
Enhanced Vision produces extremely sharp, detailed images of even faint astronomical objects by accumulating their light and projecting it into the telescope’s eyepiece. Enhanced Vision technology mimics the light gathering capability of significantly larger reflector telescopes, thus delivering unprecedented views of night-sky objects previously inaccessible to amateur astronomers.

19 juillet 2017 Mountain View, Californie, Etats Unis et Meyreuil, France — L’Institut SETI et la start-up française Unistellar annoncent aujourd’hui un partenariat, dans le but de commercialiser un nouveau télescope offrant aux astronomes amateurs une qualité d’observation du ciel sans précédent, ainsi que l’opportunité de contribuer de façon déterminante aux dernières découvertes des astronomes professionnels.
L’eVscopeTM (Enhanced Vision Telescope) d’Unistellar atteint cet objectif grâce à trois fonctions qui n’ont jamais encore été rassemblées au sein d’un appareil compact et destiné au grand public:
La Vision Amplifiée, qui fournit des images exceptionnelles, fines et détaillées des objets astronomiques les plus lointains en accumulant la lumière et en la projetant directement dans l’oculaire du télescope. La technologie de la Vision Amplifiée remplace la capacité qu’ont les grands télescopes à accumuler la lumière, et fournit ainsi à l’oculaire de l’eVscope des images du ciel jusqu’à présent inaccessibles aux astronomes amateurs.
Sarah Blunt, REU student class of 2015, is today a full member of the Gemini Planet Imager Exoplanet Survey. Together with SETI researcher Eric Nielsen and Franck Marchis, she has developed an innovative method to fit the orbits of directly imaged exoplanets. She has published her work in Astronomical Journal and is a recipient of an NSF Graduate Research Fellowship that will fund her graduate school. Here her story. (more…)
Today, NASA-funded scientists announced a major new step in the search for life on Enceladus, Saturn’s sixth-largest moon, thanks to new data collected by the NASA/ESA Cassini mission.
Enceladus has attracted a lot of interest because it has an active pole that spews jets of material into outer space. During its last flyby over that pole, an instrument on board the Cassini spacecraft detected the presence of a biomarker—molecular hydrogen. This suggests that the ocean we know lies beneath the moon’s surface could indeed contain an ecosystem similar to the ones we find in deep-sea hydrothermal vents on Earth. (more…)
In May 2016, Michael Gillon and his team announced the discovery of three Earth-sized exoplanets around TRAPPIST-1, an ultra cool M-dwarf star, using the small TRAPPIST telescope at ESO-La Silla, Chile. It was an exciting discovery—yet on that day no one could possibly have imagined that less than a year later they would make another significant discovery involving the same system. But here we are: today, they announced in Nature the discovery of seven potentially habitable Earth-like worlds.
The star, named TRAPPIST-1, is a fairly inconspicuous star in our Milky Way. Small (8% the mass of the sun) and cold (half the temperature of the sun), it is a member of an ultra-cool dwarf population that represents 15% of the star population of our galaxy. In 2016, Gillon and his team detected the transit (i.e., the shadow of a planet passing between its host star and us) of three exoplanets at the inner edge of the habitable zone of their star.
Using a combination of space telescope data, as well as recent data acquired with the SOFIA Airborne telescope and lab experiments, a team of astronomers including researchers from the SETI Institute and Jet Propulsion Laboratory have revealed the presence of dust of exogenic origin at the surface of dwarf planet Ceres. This contamination likely stems from a dust cloud formed in the outer part of the main belt of asteroids following a collision in recent times. That study challenges the relationship proposed between Ceres and asteroids in the C spectral class and instead suggests an origin of this dwarf planet in the transneptunian region. This study was published on January 19 2017 in Astronomical Journal.
I co-organized a session for the AGU 2016 meeting entitled “P42A: Solar System Small Bodies: Asteroids, Satellites, Comets, Pluto, and Charon“. Below the info on the session and the schedule.
We have three invited talks that will describe the New Horizons data of Charon, color of Kuiper Belt Object from a ground-based survey and a theoretical study of the formation of the asteroid belt.
Abstract: The composition and physical properties of Small Solar System Bodies
(SSSBs), asteroids and dwarf planets, remnants of the formation of planets, are key to better understand our solar system. Increased knowledge of their surface properties and their potential as resources are also necessary to prepare for robotic and human
exploration. Hints about the internal structure and composition of SSSBs
have been acquired recently thanks to flyby/rendezvous data from space
missions, study of complex multiple asteroid systems, or close encounter
between asteroids. In this session we will discuss results bringing
information on the internal structure and composition of SSSBs based on
space and ground-based data, numerical models, as well as instrument/mission
concepts in the prospect of future exploration. (more…)
AGU Fall meeting is starting tomorrow. I co-organized a session entitled “Detection and Direct Imaging of Habitable Exoplanets: Progress and Future” to discuss the potential of new and future facilities and modeling efforts designed to detect, image and characterize habitable exoplanets, studying their formation, evolution and also the existence of possible biospheres. Topics that are covered in this session include signs of exoplanet habitability and global biosignatures that can be sought with upcoming instrumentation; instrument requirements and technologies to detect these markers; strategies for target selection and prioritization; and impacts of planetary system properties, ground-based and space telescope architectures.
We have two invited talks, one by George Ricker on TESS and a second one by Shawn D Domagal-Goldman on HabEx, two NASA missions that could play a major role on identification and characterization of Earth-Like exoplanets.
