A team of researchers led by astronomer Ivan Ramirez of The University of Texas at Austin has identified the first “sibling” of the sun — a star almost certainly born from the same cloud of gas and dust as our star.
Astronomers led by Karl Gebhardt of The University of Texas at Austin have measured the most massive known black hole in our cosmic neighborhood by combining data from a giant telescope in Hawai'i and a smaller telescope in Texas.

Peruvian astronomers Jorge Melendez of The Australian National University and Ivan Ramirez of The University of Texas at Austin have discovered the best “solar twin” to date, using the 2.7-meter Harlan J. Smith Telescope at McDonald Observatory. Their findings suggest that the Sun’s chemical composition is not unique, as some previously thought.
