Solar Telescope Observing @ Saguaro NP – East

October 5, 2025 @ 1:00 pm 3:00 pm

Event cancelled due to Government shutdown.

Join the Tucson Amateur Astronomy Association (TAAA) and Saguaro National Park – East for some Sun gazing at the park. We will observe the Sun through telescopes with appropriate filters so you will get to see sunspots, prominences, flares, and more.
The Sun is nearing its peak in the sunspot cycle so there is lots of activity on its surface.

This event is FREE and open to the public, no reservations required.  NPS admission fees apply.

The telescopes will be set up at the Bicycle Ramada next to the Visitors Center.
This event will most likely be canceled in the event of clouds/rain.

HYBRID – General Meeting – October 2025

October 3, 2025 @ 6:30 pm 8:00 pm

Title: “The Search for Life on Exoplanets”

Telescopic facilities capable of searching for signs of life on exoplanets orbiting other stars are coming online just as experiments simulating the emergence of life on Earth are making revolutionary discoveries. Dr. Sukrit Ranjan will discuss recent progress towards both goals, with emphasis on new opportunities unveiled by the James Webb Space Telescope and the future planned Habitable Worlds Observatory, NASA’s proposed infrared/optic/ultraviolet space telescope to primarily search for exoplanets in the habitable zones of stars.

Biography:

Sukrit is a planetary scientist focused on questions related to the origin of life on Earth and the search for life on other worlds. These questions are coupled: efforts to understand the origin of life on Earth helps guide our search for it elsewhere in the cosmos, while observations of other planets help us test our theories of the prebiotic environment and of abiogenesis. To understand abiogenesis, he works to constrain the palette of environmental conditions from which life arose on Earth, to guide experimental studies of the origin of life. To search for life elsewhere, he works to determine observational tests by which life on other worlds may be remotely discriminated. Sukrit completed his PhD in Astronomy & Astrophysics at Harvard University, followed by a SCOL postdoctoral fellowship at MIT EAPS and a CIERA postdoctoral fellowship at Northwestern. He completed his undergraduate work at MIT in physics. More information about Sukrit is available at his faculty profile here: https://www.lpl.arizona.edu/faculty/sukrit-ranjan
