How I Plan to Help Save Science Education with the Unistellar eVscope!
Published 10/2/2020 in Dan's Cosmic Diary Author Dan Peluso
Lightning strikes a dream Several weeks ago I had a dream during the intense lightning storms in and around San Francisco and the greater Bay Area, which then sparked some of the devastating wildfires that we are still recovering from and experiencing. In this dream, I was in my high school chemistry class. My group was asked to answer the problem on the board and when we went up and didn’t know the answer, everyone, including the teacher (and Nelson from the Simpsons), laughed at us. This inspired me to share the failure of the American education system with my students and... read more ❯

An occultation by the Potentially Hazardous Asteroid 1998 RO2 - Occultation par l'astéroïde géocroiseur 1998RO2
Published 4/13/2020 in Franck Marchis Blog Author inesdemuys
1998RO2 is a  body classified as a potentially hazardous asteroid that has been and will be mentioned in the news  in the next 2 weeks. With a diameter estimated to 2-4 km, it's one of the largest asteroid with this classification. First of all, let's clarify that we can say with confidence that it will NOT hit Earth since its orbit is well  characterized with occultations collected since its discovery in 1998. We know that it will make a close flyby to Earth by the end of April 2020 and will be visible with binocular and naked eye from very... read more ❯

New Unistellar eVscope exoplanet light curve and exoplanet targets this weekend!
Published 4/10/2020 in Dan's Cosmic Diary Author Dan Peluso
Dear Unistellar eVscope users, With your Unistellar eVscope you have the technology to detect planets orbiting other stars. Think about this--over 30 years ago planets around other stars (exoplanets) were hypothesized, but none yet were detected. Since the most agreed upon "first detection" of an exoplanet in 1992 around a pulsar, astronomers have detected thousands of exoplanets, but this has been done mostly through the use of expensive remote telescopes and highly technical techniques. Now, you and your eVscope can observe exoplanets with a few clicks on your smartphone and some time. I've been posting exoplanet targets for you and me to... read more ❯

Comet Atlas: A comet for all of us?
Published 4/1/2020 in Franck Marchis Blog Author Franck Marchis
Finally! After several years of waiting we may soon have, in Comet ATLAS, a bright, naked-eyed comet passing by Earth. The last visitor to do this was Comet 46P/Wirtanen, which was barely visible in December 2018 from highly polluted areas. Current models predict that Comet ATLAS could be brighter and easy to spot in the sky even for novice citizen astronomers. Of course, anyone who has a telescope can already witness brightness and morphological changes in the comet at it approaches the Sun. If, like a lot of us, you’re sheltering at home, this is the ideal time to look... read more ❯

Look up and let the stars lift your spirits AND exoplanet targets for Unistellar eVscope users!
Published 3/27/2020 in Dan's Cosmic Diary Author Dan Peluso
Dear Cosmic Diary guests and Unistellar eVscope users, My heart and best wishes go out to you and to your families during the COVID-19 global crisis. I have been very busy adjusting to this new way of life in quarantine and social distancing to do my part in "flattening the curve" and staying safe, as I'm sure many of you also have. In addition to being a PhD student, I also teach high school physics full-time and my school in the Bay Area, CA, closed down for the pandemic on Friday, March 13. My teacher colleagues and I began teaching completely online... read more ❯

MISSION UNISTELLAR : OCCULTATION PAR L'ASTÉROÏDE SIBERIA - UNISTELLAR MISSION : AN OCCULTATION BY SIBERIA ASTEROID
Published 3/24/2020 in Franck Marchis Blog Author inesdemuys
--- Version française --- The english version is available below. À tous les citizen astronomes d'Unistellar, Si vous possédez un eVscope et que vous souhaitez participer à une campagne de science participative, vous pouvez suivre les instructions ci-dessous. Cette campagne est très simple. Grâce à l'application Unistellar, votre mission se résumera à l'observation d'une étoile lorsqu'elle est occultée par un astéroïde. L'occultation que nous vous proposons d'observer concerne les personnes qui résident dans la zone entre les deux lignes rouges (voir ci-dessous). L'astéroïde (1094) Siberia occultera une étoile de magnitude 11,3 pendant 1,8 seconde ce samedi 28 Mars 2020 aux alentours de 00h58 (heure... read more ❯

TONIGHT: NASA TESS exoplanet target for Unistellar eVscope users on March 7.
Published 3/8/2020 in Dan's Cosmic Diary Author Dan Peluso
Dear Unistellar eVscope users, Since it was very cloudy last night in California, I thought I'd post another target since forecasts predict only partly cloudy skies tonight. Be sure to check your weather, and be especially careful for any rain, but if the stars align, then go get some exoplanet data!!! ;) Background Information (skip to the observing directions, if you've seen this before) If you have not seen my previous posts on this topic, my name is Dan Peluso and I am doing my PhD in astrophysics with Franck Marchis (astronomer at the SETI Institute) and as a portion of my research... read more ❯

Occultation by Nyanza on President Day across the US
Published 2/13/2020 in Franck Marchis Blog Author Franck Marchis
Hello, If you have an eVscope and you want to participate to a scientific campaign on Presidents’ Day, this is something that may interest you. The asteroid 1356 Nyanza will occult a V-12.2 star for up to 6 seconds on February 17 at ~8pm PST and 11pm EST. Yes! This occultation will be visible across the US, from Redding, CA to Philadelphia, PA and Chicago, IL. If a large number of eVscope users observe this event, we will be able to derive the size, shape and eventual existence of moons around the asteroid. So don't wait and take your eVscope out if... read more ❯
