University of Texas at Austin astronomer Andrew Mann and colleagues have discovered a planet in a nearby star cluster which could help astronomers better understand how planets form and evolve. The discovery of planet K2-25b used both the Kepler space telescope and the university's McDonald Observatory, and is published in a recent issue of the Astrophysical Journal.
Astronomer Natalie Gosnell has used Hubble Space Telescope to better understand why some stars aren't evolving as predicted. These so-called "blue stragglers" look hotter and bluer than they should for their advanced age. It's almost as if they were somehow reinvigorated to look much younger than they really are.
This is the second of a three-part series on general relativity.
Einstein's Theory of General Relativity, which describes how gravity works, turns 100 this month. The theory has successfully explained a lot of what we observe out in the universe; but there are signs that it's incomplete. In the 1990s, astronomers observed that the expansion of the universe is speeding up, as if some mysterious force is pushing everything apart faster and faster. Nearly 20 years later, one of the biggest unanswered questions in science is: what is this dark energy? Not only was dark energy not predicted by general relativity, but its mere existence might mean that the theory needs to be tweaked or even replaced.
Leaders and supporters from The University of Texas at Austin's McDonald Observatory, along with representatives from an international group of partner universities and research institutions, are gathering on a remote mountaintop high in the Chilean Andes today to celebrate groundbreaking for the Giant Magellan Telescope (GMT).
After several years and a massive team effort, one of the world's largest telescopes has opened its giant eye again. The Hobby-Eberly Telescope (HET) at The University of Texas at Austin's McDonald Observatory has completed a $25 million upgrade and, now using more of its primary mirror, has achieved "first light" as the world's third-largest optical telescope.
Assistant professor and astronomer Steve Finkelstein can travel through time. Well, almost. He uses data from the Hubble Space Telescope to gaze beyond to the most distant galaxies in the universe. He studies galaxy evolution, and is on a quest to discover the origins of our Milky Way and life itself.
As part of a continuing tradition, we invited faculty, staff and students in the College of Natural Sciences community to send us images this past spring that celebrated the magnificent beauty of science and the scientific process. Our goal was to find those moments where science and art become one and the same.
The College of Natural Sciences welcomes 11 new faculty this fall. Whether searching for evidence of exotic new physics, enabling the creation of personal robots, or addressing critical problems in cancer research, these industrious and innovative faculty members build on the college's reputation for pioneering research and research-based teaching.
The Giant Magellan Telescope (GMT) has announced a major milestone today with 11 international partners including The University of Texas at Austin unanimously approving its construction, securing the future of the project with more than $500 million to begin work on the world's most powerful optical telescope. The decision initiates final design and fabrication of the GMT, which is poised to become the largest optical telescope in existence.
Like a newborn's foggy vision slowly coming into focus, the Hubble Space Telescope has enabled humanity to see more clearly than ever before the world beyond our noses, a cosmos of contradictions: incandescent and quiescent, violent and benevolent, chaotic and orderly.
A Department of Astronomy outreach program achieved the culmination of 17 years of hard work recently when several Texas teachers flew as part of the science team aboard NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA).
Astronomer Andrew Mann of The University of Texas at Austin has been awarded a Hubble Fellowship from NASA and the Space Telescope Science Institute, science center for the Hubble Space Telescope.
A team of scientists including The University of Texas at Austin’s Dr. William Cochran has discovered a solar system similar to our own dating back to the dawn of our Milky Way galaxy. They are reporting the find of five planets with sizes between Mercury and Venus orbiting the Sun-like star Kepler-444 in today’s issue of The Astrophysical Journal.
A five-year analysis of an event captured by a tiny telescope at McDonald Observatory and followed up by telescopes on the ground and in space has led astronomers to believe they witnessed a giant black hole tear apart a star. The work is published this month in The Astrophysical Journal.
Read our publication, The Texas Scientist, a digest covering the people and groundbreaking discoveries that make the College of Natural Sciences one of the most amazing and significant places on Earth.
