A team of University of Arizona researchers is working to scale up production of carbon-absorbing marine algae in an effort to curb the worst impacts of climate change.

As a University of Arizona professor of astronomy and planetary sciences who studies planets orbiting other stars, Daniel Apai spends much of his...

A UArizona research team plans to harness principles of the carbon cycle to trap massive amounts of carbon dioxide and curb the worst impacts of climate change. Their secret weapon? Algae.

  Since 1995 when exoplanet explorers from the Geneva Observatory in Switzerland, Michel Mayor and Didier Queloz –who were recently awarded half of the 2019 Nobel Prize in Physics for their discovery of a planet orbiting a sunlike star named 51 Pegasi– thousands of extrasolar planets have been found, including potentially Earth-like worlds, along with bizarre objects that bear no resemblance to any of the planets in our solar system. Twenty-Six Years Later… Twenty-six years later, it is ...

January 18, 2021 The surface features of brown dwarfs – objects midway in mass between planets and stars – can’t be seen. But researchers have found a way to reveal Jupiter-like stripes and bands in the atmosphere of the closest brown dwarf, Luhman 16B. Recently, we showed you a cool new direct image taken of a brown dwarf, an object midway in mass between a planet and a star. But that image doesn’t show the brown dwarf’s surface features. No existing image does. These objects are t...

What Does the Closest Brown Dwarf Look Like? by Paul Gilster on January 13, 2021 I keep hoping we’ll find a brown dwarf closer to us than Alpha Centauri, but none have turned up yet despite the best efforts of missions like WISE (Wide-Field Infrared Survey Explorer). If there’s something out there, it’s dim indeed. Of course, I wouldn’t be surprised at finding rogue planets between us and the nearest stars. Maybe some will be more massive than Jupiter, but evidently not mass...

Striped or Spotted? Winds and Jet Streams Found on the Closest Brown Dwarf Planetary scientists wondered if bands of winds or swirling storms dominated the atmospheres of brown dwarfs. UArizona-led research has solved the mystery. By Mikayla Mace Kelley, University Communications Jan. 7, 2021 Using high-precision brightness measurements from NASAs TESS space telescope, astronomers found that the nearby brown dwarf Luhman 16Bs atmosphere is dominated by high-speed, global winds akin...
