NASA Features New Discoveries at American Astronomical Society Meeting

Hubble Space Telescope data are shown in green and blue; Chandra data are shown in purple. Together they form a brilliant cluster of stars.

Experts will discuss new research from NASA missions at the 243rd meeting of the American Astronomical Society (AAS), on topics ranging from planets outside our solar system to fleeting, high-energy explosions in the universe. The meeting will take place Jan. 7-11 at the New Orleans Ernest N. Morial Convention Center in New Orleans.

In press conferences, scientific sessions, and town halls, scientists and agency leaders will present the latest developments in astrophysics. Press conferences – highlighting results enabled by NASA missions such as the James Webb Space Telescope (also called “Webb” or “JWST”), Hubble Space Telescope, Chandra X-ray Observatory, and Fermi Gamma-ray Space Telescope – will stream live to the public on the AAS Press Office YouTube channel.

In addition to press conferences, NASA highlights for registered attendees include:

  • NASA Town Hall: Monday, Jan. 8, 12:45 p.m. CST
  • James Webb Space Telescope Town Hall: Wednesday, Jan. 10, 6 p.m. CST
  • Nancy Grace Roman Space Telescope Town Hall: Thursday, Jan. 11, 12:45 p.m. CST

Throughout the week, expert talks at the NASA Exhibit Booth will discuss science from current NASA missions including Webb, Hubble, IXPE (Imaging X-ray Polarimetry Explorer), NICER (Neutron star Interior Composition Explorer), TESS (Transiting Exoplanet Survey Satellite), and Chandra ahead of its 25th anniversary; NASA’s upcoming Nancy Grace Roman Space Telescope and SPHEREx observatory; the Habitable Worlds Observatory, a concept for a future NASA flagship space telescope; the agency’s scientific Balloon Program; the 2024 total solar eclipse; and open science at NASA, among other topics.

Members of the media can request interviews with NASA experts on any of these topics by contacting Alise Fisher at alise.m.fisher@nasa.gov.
