Distance to the Cygnus Loop Comes Into Clearer Focus

Distance to the Cygnus Loop Comes Into Clearer Focus

The Cygnus Loop is the ethereal wreckage of a supernova explosion that occurred some 17,000-25,000 years ago. It is a cloud of dust and gas, called a nebula, steadily expanding outward from the original blast site. Because it is relatively close to us – and beautiful! - it is a popular target for amateur astronomers exploring the cosmos through backyard telescopes. Its neighborly status also makes it a popular target for professional astronomers studying the aftereffects of supernovae.

Galaxies Actively Forming in Early Universe Caught Feeding on Cold Gas

Galaxies Forming in Early Universe Caught Feeding on Cold Gas

Researchers analyzing data from NASA’s James Webb Space Telescope have pinpointed three galaxies that may be actively forming when the universe was only 400 to 600 million years old. Webb’s data show these galaxies are surrounded by gas that the researchers suspect to be almost purely hydrogen and helium, the earliest elements to exist in the cosmos. 

These findings are published in the May 24 issue of the journal Science.

Winter Board of Visitors Meeting Explores Artificial Intelligence

Winter Board of Visitors Meeting Explores Artificial Intelligence

The 2024 Board of Visitors Winter Meeting took place February 23-24 at The University of Texas at Austin. Over 150 Board of Visitors members attended.

Through a series of talks, the event explored some of the ways artificial intelligence (AI) is making an impact within UT’s Astronomy Department and McDonald Observatory, and how it may shape the future of scientific research.

Astronomers Uncover Methane Emission on a Cold Brown Dwarf

Astronomers Uncover Methane Emission on a Cold Brown Dwarf

Using new observations from the James Webb Space Telescope (JWST), astronomers have discovered methane emission on a brown dwarf, an unexpected finding for such a cold and isolated world. Published today in the journal Nature, the findings suggest that this brown dwarf might generate aurorae similar to those seen on our own planet as well as on Jupiter and Saturn.
