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.

April 8 Partial Eclipse at McDonald Observatory

April 8 Partial Eclipse at McDonald Observatory

On Monday, April 8, parts of North America will experience a total solar eclipse. This happens when the Moon passes between the Earth and Sun, completely covering the Sun’s disk. The brief moment when the Sun is 100% covered is called “totality.” To see it, you must be within the “path of totality,” a narrow band about 100 miles wide.

The path of totality for April’s eclipse travels from Mazatlán, Mexico, to the island of Newfoundland, Canada. It will sweep into the Lone Star State at Eagle Pass and exit near Texarkana. 

Discovery of Unexpected Ultra-Massive Galaxies May Not Rewrite Cosmology, But Still Leaves Questions

Discovery of Ultra-Massive Galaxies May Not Rewrite Cosmology

Ever since the James Webb Space Telescope (JWST) captured its first glimpse of the early Universe, astronomers have been taken aback by the presence of what appear to be more “ultra-massive” galaxies than expected. Based on the most widely accepted cosmological model, they shouldn’t have been able to evolve until much later in the history of the Universe, spurring claims that the model needs to be changed. 

This would upend decades of established science.

LightSound Workshops Make April’s Eclipse More Accessible to Visually Impaired

LightSound Workshops Make April’s Eclipse More Accessible

Through a series of workshops held January 28 and 29 by the LightSound Project and with the support of the UT Austin Department of Astronomy, the University community built 140 LightSound devices. By converting light into sound, these handheld devices make solar eclipses more accessible to the blind and low vision community.
