Upgraded Hobby-Eberly Telescope Sees First Light

by Rebecca Johnson

FORT DAVIS, Texas — 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.

Dying Stars Suffer from 'Irregular Heartbeats'

Dying Stars Suffer from 'Irregular Heartbeats'

AUSTIN — Some dying stars suffer from ‘irregular heartbeats,’ research led by astronomers at The University of Texas at Austin and the University of Warwick has discovered.

The team discovered rapid brightening events — outbursts — in two otherwise normal pulsating white dwarf stars. Ninety-seven percent of all stars, including the Sun, will end their lives as extremely dense white dwarfs after they exhaust their nuclear fuel. Such outbursts have never been seen in this type of star before.

Texas Astronomers Help Find Earth’s Older, Bigger Cousin

Texas Astronomers Help Find Earth’s Older, Bigger Cousin

AUSTIN — University of Texas at Austin astronomers working with NASA’s Kepler mission have helped to discover the first near-Earth-sized planet around a Sun-like star in the “habitable zone,” the range of distances where liquid water could pool on a planet’s surface. They used the university’s McDonald Observatory to help confirm the finding, which has been accepted for publication in The Astronomical Journal.

“We are pushing toward Earth 2.0,” McDonald Observatory astronomer Michael Endl said. “This planet is probably the most similar to Earth yet found.”
