Exoplanets

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 ❯

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 ❯

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 ❯

Dear Unistellar eVscope users, It's time for another Unistellar eVscope exoplanet citizen science campaign. We would love your help observing some exoplanets, so if you want to join us in some planet hunting, then charge up your eVscopes and get ready because we need your help this weekend!

Dear Unistellar eVscope users, It's time for another Unistellar eVscope exoplanet citizen science campaign. We would LOVE (Happy Valentine's Day by the way) your help observing some exoplanets, so if you want to join us in some planet hunting, then charge up those eVscopes and get ready because we need your help over the next few weekends!

Dear Unistellar eVscope users, Today is my birthday and for a gift, I want you to be involved in something innovative like participating in the very first second Unistellar exoplanet detection campaign? Then charge up those eVscopes and get ready because we need your help tonight to try and observe a NASA TESS exoplanet!

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 I want to see if it is possible for any astronomy enthusiast around the world to coordinate with planet hunting scientists like us to help contribute to the search for planets around other stars (a.k.a. exoplanets). Exoplanet searches usually... read more ❯

Eric Nielsen, formerly a post-doc at the SETI Institute and now a researcher at Stanford University, led a study of the planet beta Pictoris b that combined direct observation of the planet recorded with the Gemini Planet Imager with additional data from space and ground-based observations. The team estimated the mass of this distant planet to be eight to sixteen times that of Jupiter and found that it likely has an elliptical orbit. A video shows the motion of the planet around its star, something that was inconceivable fifteen years ago. Since it was installed on the Gemini-South telescope in 2013,... read more ❯

A team of astronomers led by Bin Ren (The Johns Hopkins University) imaged the debris disk system around star HD 191089 using the GPI instrument, located at 160 light-year away from us. The structure of the debris disk around this younger sibling of our Sun is strikingly similar to our own Kuiper Belt. New technology available maybe in 2030s, like the giant space telescopes (HabEx & LUVOIR) could one day tell if there is also an Earth 2.0 with the Belt delivering water right now, or is there an exotic world that we have never seen or imagined, or maybe... read more ❯
