Theft behind Planet 9 in our solar system
Through a computer-simulated study, astronomers at Lund University in Sweden show that it is highly likely that the so-called Planet 9 is an exoplanet. This would make it the first exoplanet to be discovered inside our own solar system. The theory is that our sun, in its youth some 4.5 billion years ago, stole Planet 9 from its original star.

NASA's Webb Telescope to make a splash in search for interstellar water
Water is crucial for life, but how do you make water? Cooking up some H2O takes more than mixing hydrogen and oxygen. It requires the special conditions found deep within frigid molecular clouds, where dust shields against destructive ultraviolet light and aids chemical reactions. NASA's James Webb Space Telescope will peer into these cosmic reservoirs to gain new insights into the origin and evolution of water and other key building blocks for habitable planets. (2018-03-09)

Footprints of baby planets in a gas disk
A new analysis of the ALMA data for a young star HL Tauri provides yet more firm evidence of baby planets around the star. Researchers uncovered two gaps in the gas disk around HL Tauri. The locations of these gaps in the gas match the locations of gaps in the dust. This discovery supports the idea that planets form in much shorter timescales than previously thought and prompts a reconsideration of alternative planet formation scenarios. (2016-05-24)

No planets needed: NASA study shows disk patterns can self-generate

A 'hot Jupiter' with unusual winds
The hottest point on a gaseous planet near a distant star isn't where astrophysicists expected it to be -- a discovery that challenges scientists' understanding of the many planets of this type found in solar systems outside our own. (2018-01-22)

Best region for life on Mars was far below surface
The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a Rutgers-led study concludes. The study, published in the journal Science Advances, may help resolve what's known as the faint young sun paradox - a lingering key question in Mars science. (2020-12-02)

A new Goldilocks for habitable planets
The search for habitable, alien worlds needs to make room for a second 'Goldilocks,' according to a Yale University researcher. A new study, appearing in the journal Science Advances on Aug. 19, suggests that simply being in the habitable zone isn't sufficient to support life. A planet also must start with an internal temperature that is just right. (2016-08-19)

A new 'atmospheric disequilibrium' could help detect life on other planets
A new study has found a simple approach to look for life that might be more promising than just looking for oxygen. (2018-01-24)

Brown dwarfs, the larger cousins of giant planets, undergo atmospheric changes from cloudy to cloudless as they age and cool. A team of astronomers measured for the first time the temperature at which this shift happens in young brown dwarfs. Their findings, published by The Astrophysical Journal Letters, may help them better understand how gas giant planets like our own Solar System's Jupiter evolved. (2018-02-27)

Ultracool dwarf and the 7 planets
Astronomers have found a system of seven Earth-sized planets just 40 light-years away. They were detected as they passed in front of their parent star, the dwarf star TRAPPIST-1. Three of them lie in the habitable zone and could harbor water, increasing the possibility that the system could play host to life. It has both the largest number of Earth-sized planets yet found and the largest number of worlds that could support liquid water. (2017-02-22)

OU astrophysicists discover planets in extragalactic galaxies using microlensing
A University of Oklahoma astrophysics team has discovered for the first time a population of planets beyond the Milky Way galaxy. Using microlensing--an astronomical phenomenon and the only known method capable of discovering planets at truly great distances from the Earth among other detection techniques--OU researchers were able to detect objects in extragalactic galaxies that range from the mass of the Moon to the mass of Jupiter. (2018-02-02)

Earth's stable temperature past suggests other planets could also sustain life
Research about temperatures on the early Earth have ranged from a virtually ice-covered surface to a very hot planet that could not support most of today's lifeforms. New computer simulations show fairly moderate average temperatures and more stable ocean pH -- which helps explain how life evolved here, and might emerge on other planets. (2018-04-02)

Mars and Venus are surprisingly similar
Using two ESA spacecraft, planetary scientists are watching the atmospheres of Mars and Venus being stripped away into space. The simultaneous observations by Mars Express and Venus Express give scientists the data they need to investigate the evolution of the two planets' atmospheres. (2008-03-05)
