An international research team led by the University of Göttingen has discovered two new Earth-like planets near one of our closest stars. 'Teegarden's star' is about 12.5 light years away and is one of the smallest known stars. It is about 2,700°C and about 10 times lighter than the sun. The star wasn't discovered until 2003. The scientists observed the star for about three years. The results were published in Astronomy and Astrophysics.
Researchers at the US Naval Research Laboratory have discovered a remnant of ancient dust inside a primitive meteorite.
The sun's rotation rate in its first billion years is unknown. Yet, this spin rate affected solar eruptions, influencing the evolution of life. A team of NASA scientists think they've figured it out by using the moon as critical evidence.
In a new paper that appeared in Science on Friday and includes two University of Central Florida co-authors, researchers are offering glimpses into the nature and composition of Saturn's legendary rings by using data from some of the closest observations ever made of the main rings.
Researchers think they've solved the long-standing mystery of how Mars got all of its clouds.
Based on preliminary results from a new Gemini Observatory survey of 531 stars with the Gemini Planet Imager (GPI), it appears more and more likely that large planets and brown dwarfs have very different roots.
New research by a University of Guelph physicist suggests most of Earth's heavy metals were spewed from a largely overlooked kind of star explosion called a collapsar.
A survey of 300 stars in search of exoplanets finds that massive, Jupiter-like gas giants are found just about where Jupiter is in our own solar system. Most such massive planets occur around stars weighing 1.5 solar masses, with few around sun-like stars. Though the Gemini Planet Imager Exoplanet Survey found just six planets and three brown dwarfs around these 300 stars, the survey provides much-needed statistics on large planet masses and orbits.
New insight on Europa's geochemistry was hiding in the visible spectrum.
Analysis from halfway through the Gemini Planet Imager's planetary survey hints that our solar system may have rare qualities which could possibly be related to the habitability of Earth.
