Astronomers spot 'super-Earth' 80 light years away
US astronomers have detected the second smallest exoplanet ever discovered with a mass just four times heavier than the Earth, adding to a growing number of low-mass planets dubbed "super-Earths."
The Hot Saturn Exoplanet
(PhysOrg.com) -- Of the roughly 350 known exoplanets (i.e., extrasolar planets), the one orbiting the star HD149026 is unique.
Detecting Life-Friendly Moons
The search for life-friendly real estate around distant stars doesn't have to be limited to planets. New research shows that habitable exomoons can be detected with a new method using current technology.
Earth's sister in the crosshairs
Earth’s sister is out there, somewhere, and scientists searching for planets that may support life believe they are closing in on finding just that.

In the zone: How scientists search for habitable planets
There is only one planet we know of, so far, that is drenched with life. That planet is Earth, as you may have guessed, and it has all the right conditions for critters to thrive on its surface. Do other ...
Odd discovery may help refine theories about how planets form
An international team of researchers has found a planet around another star whose orbit is steeply tilted from the plane of the star's equator, a finding that contradicts some theories about how solar systems form.
NASA's HyspIRI: Seeing the forest and the trees and more
To Robert Green, light contains more than meets the eye: It contains fingerprints of materials that can be detected by sensors that capture the unique set of reflected wavelengths. Scientists have used the ...
