The Legacy of the Spitzer Space Telescope and You 
Sean Carey (Caltech/IPAC)

4-4:30 pm EDT/1-1:30 pm PDT 

NASA's Spitzer Space Telescope ceased collecting science data in January 2020 after 16+ years of operations. We’ll show you to access the entire mission archive and resources that will help you use this rich dataset for your science.


Using the NEID Precision Radial Velocity Spectrograph

Sarah Logsdon (NOIRLab)

4:30-5 pm EDT/1:30-2 pm PDT

The NEID spectrograph on the WIYN 3.5m telescope at Kitt Peak National Observatory has been recently commissioned and is available for general observer observations of approximately 37 nights per semester available through the NN-EXPLORE program.  NEID provides high resolution spectroscopy (R~60000-110000) from 380-930 nm capable of producing with radial velocities with precisions to 30 cm/s.  This webinar will describe how to apply for time, an overview of the capabilities of the instrument, what data products are available, and how to access them from the NEID archive at NExScI.

Public Engagement Opportunities with NASA’s Universe of Learning

4-4:30 pm EDT/1-1:30 pm PDT


NASA’s Universe of Learning creates resources and experiences for museums, libraries and science centers, such as AstroPix, Viewspace, Girls STEAM Ahead with NASA, and Science Briefings. They allow learners to explore the universe and how science is done, incorporating data and resources from across NASA Astrophysics. We rely on subject matter experts (like you!) to ensure that the science content presented in our products and programs are timely, accurate, and reflect science driving current research.
We are actively seeking subject matter expert volunteers from multiple institutions and missions across all of its projects. We have opportunities that span a range of time commitments and levels of direct and/or indirect engagement with audiences. They include:
  • Working with science centers/museums on their exhibits/programming.
  • Being interviewed.
  • Providing astrophysics content or content review.
  • Giving a presentation.
  • Facilitating a demonstration or activity.
This webinar will give an overview of NASA’s Universe of Learning, then show you how to become part of our subject matter expert database and be matched with programs that are looking for volunteers with your interests.

Science from the Stratosphere: What’s New with SOFIA 

 noon-12:30 pm EDT/9-9:30 am PDT

SOFIA’s mid- and far-infrared observations are uncovering new clues about the birth of stars and planets, our interstellar origins and the path to life, magnetic fields and the distant universe. Join SOFIA Mission Operations Director Margaret Meixner to learn about recent science results, current observing and funding opportunities, and planning for future instrumentation development.


New Content and Capabilities in the NASA/IPAC Extragalactic Database
Joseph Mazzarella (Caltech/IPAC-NED)
12:30-1 pm EDT/9:30-10 am PDT 
NED is a comprehensive database of multiwavelength data for extragalactic objects, providing a systematic, ongoing fusion of information integrated from hundreds of large sky surveys and tens of thousands of research publications. We will highlight recent updates to content and user interface capabilities.
US Archival Science with Euclid

Euclid is an ESA mission, with NASA involvement, to study the nature and geometry of the dark universe, with launch planned in mid-2022. Euclid will survey the extragalactic sky, obtaining near-infrared and wide-band optical imaging, as well as NIR grism spectra. All Euclid data will be made public to the world-wide community within 2 years of acquisition. The Euclid NASA Science Center at IPAC (ENSCI; will support Euclid research by the US community. In this webinar, we will give an overview of the mission and the opportunity for US-based archival research.

Accessing NASA's Astrophysics Archives Using Python

Xiuqin Wu (Caltech/IPAC-NED), David Shupe (Caltech/IPAC),  

11 am-1 pm EDT/9-11 am PDT

NASA's Astrophysics Archives preserve many terabytes of multi-wavelength images, catalogs, and spectra. While many astronomers are familiar with the web tools that are convenient for searching and visualizing these data, programmatic interfaces through Python are increasingly in demand. This hands-on workshop will introduce participants to the programmatic data access tools available and the tutorial notebooks NAVO offers. We will describe science scenarios that combine multi-wavelength data from the HEASEARC, IRSA, NED, and MAST that participants will then be encouraged to work through themselves. Workshop organizers will be available to help participants with them or adapt them for custom projects.

Science Talk: Using Proper Motions from CatWISE2020 to Uncover New Objects in the Solar Neighborhood

Tarun Kota (Eastview High School), J. Davy Kirkpatrick (IPAC/Caltech), and Dan Caselden (Gigamon Applied Threat Research)
4:40pm EDT/1:40pm PDT
In an effort to complete the census of cold objects in the solar neighborhood, we have been searching for objects such as brown dwarfs, low mass stars, white dwarfs, etc. CatWISE2020 has improved upon the motion and infrared measurements of AllWISE by leveraging archival WISE and NEOWISE data collected from 2010 to 2016 at W1 and W2 (Marocco et al. 2020). The improved astrometric accuracy will lead to the discovery of previously unrecognized high motion objects in the solar neighborhood. Using candidate selection criteria outlined in Meisner et al. 2019, we made a list of high-proper motion objects and paired them up with their 2MASS counterparts. From this list, we present the discovery of a low mass star, a subdwarf, 4 white dwarfs, 2 Brown Dwarfs and one object of "an unknown type". Additional analysis into the contaminants reveal the discovery of 2 dust obscured galaxies. We also present additional follow up on other objects published elsewhere. These discoveries were found by making color-color diagrams of the motion candidates and then manually searching for interesting outliers. We are currently pairing our list of motion objects with UHS and VHS data which will allow us to go deeper with the color color diagrams and uncover a trove of interesting objects.
