Search for Life Suggests Solar Systems More Habitable than Ours

SAN FRANCISCO — Scattered around the Milky Way are stars that resemble our own sun—but a new study is finding that any planets orbiting those stars may very well be hotter and more dynamic than Earth.

That’s because the interiors of any terrestrial planets in these systems are likely warmer than Earth—up to 25 percent warmer, which would make them more geologically active and more likely to retain enough liquid water to support life, at least in its microbial form.

The preliminary finding comes from geologists and astronomers at Ohio State University who have teamed up to search for alien life in a new way. (more…)

Study: Giant Super-Earths Made of Diamond Are Possible

SAN FRANCISCO – A planet made of diamonds may sound lovely, but you wouldn’t want to live there.

A new study suggests that some stars in the Milky Way could harbor “carbon super-Earths” – giant terrestrial planets that contain up to 50 percent diamond.

But if they exist, those planets are likely devoid of life as we know it. (more…)

Hubble to Target ‘Hot Jupiters’

An international team of astronomers led by a former UA graduate student has set out on the largest program to date exploring the alien atmospheres of “Hot Jupiters” – massive planets in solar systems far away from our own.

An international team of scientists has secured a large program of nearly 200 hours of observing time with NASA’s Hubble Space Telescope to explore the atmospheric conditions of planets outside our solar system, known as exoplanets. (more…)
