New paper on observing "Clarke Exo-belts"
Dr. Korpela and his colleagues Prof. Shauna Sallmen and Ms. Kaisa Crawford-Taylor have published a new paper today in the Astronomical Journal about whether astronomers be able to detect belts of satellites circling planets around other stars. Unfortunately, the answer is that even the thickest satellite belts will be very difficult to see with current technology. Even the James Webb Space Telescope will find it difficult.

If, like most sentient beings in the Galaxy, you don't have a subscription to the Astronomical Journal you can see a preprint of the article at arXiv.org.

Fall/Winter 2019 Funding drive has started
We've started our 2019 funding drive. Many of you have probably received our email penned by Jeff Cobb who has been in the SETI group longer than I have. If you can't wait, you can read yours here.

Because of our continued effort to be GDPR compliant, we're not sending emails to anyone with an EU/EAA email addresses, anyone who listed an EU/EAA country, or anyone who listed "International" as their country. And, of course, anyone who has opted out of our emails won't get them.

Thanks for your support!
