Life May Be Evolving on the Closest Alien Planet to Earth

Life May Be Evolving on the Closest Alien Planet to Earth

A few decades ago, we didn’t know if there were any planets outside our solar system. Thanks to advances in astronomy like Hubble and the Kepler Telescope, we now know there are uncountable planets in the universe, including at least one in the solar system next door. Researchers from Cornell

In Search of Missing Worlds, Hubble Finds a Fast Evaporating Exoplanet

This artist’s illustration shows a giant cloud of hydrogen streaming off a warm, Neptune-sized planet just 97 light-years from Earth.

Fishermen would be puzzled if they netted only big and little fish, but few medium-sized fish. Astronomers likewise have been perplexed in conducting a census of star-hugging extrasolar planets. They have found hot Jupiter-sized planets and hot super-Earths (planets no more than 1.5 times Earth’s diameter). These planets are scorching

Helium exoplanet inflated like a balloon, research shows

HAT-P-11b exoplanet

Astronomers have discovered a distant planet with an abundance of helium in its atmosphere, which has swollen to resemble an inflated balloon.An international team of researchers, including Jessica Spake and Dr David Sing from the University of Exeter, have detected the inert gas escaping from the atmosphere of the exoplanet

Scientist develops database for stellar-exoplanet ‘exploration’

stellar exoplanet

A Southwest Research Institute scientist is using big data to help the scientific community characterize exoplanets, particularly alien worlds orbiting nearby stars. Of particular interest are exoplanets that could harbor life."At first scientists focused on temperatures, looking for exoplanets in the 'Goldilocks zone'—neither too close, nor too far from the
