Two new images from NASA's James Webb Space Telescope show what may be among the earliest galaxies ever observed. Both images include objects from more than 13 billion years ago, and one offers a much wider field of view than Webb's First Deep Field image, which was released amid great fanfare July 12. The images represent some of the first out of a major collaboration of astronomers and other academic researchers teaming with NASA and global partners to uncover new insights about the universe.

An international group of astronomers led by Benjamin Thomas of The University of Texas at Austin has used observations from the Hobby-Eberly Telescope (HET) at the university's McDonald Observatory to unlock a puzzling mystery about a stellar explosion discovered several years ago and evolving even now. The results, published in today's issue of The Astrophysical Journal, will help astronomers better understand the process of how massive stars live and die.

FORT DAVIS, Texas — The University of Texas at Austin's McDonald Observatory will hold its first Dark Skies Festival Friday, April 29, and Saturday, April 30. The festival will include daytime and evening events for the whole family, plus the debut of the new "Preserving Dark Skies" exhibit in the Frank N. Bash Visitors Center. Both the exhibit and the festival are funded by Apache Corporation.

The world's largest International Dark Sky Reserve is coming to Texas and Mexico, thanks to a partnership between The University of Texas at Austin's McDonald Observatory, The Nature Conservancy, the International Dark-Sky Association (IDA) and many others. The designation, granted by the IDA, recognizes the commitment of organizations, governments, businesses and residents in the region to maintaining dark skies. The move will benefit not only astronomical research, but also wildlife, ecology and tourism.
