An international team of astronomers has captured the first-ever polarized radio waves from a distant cosmic explosion.
Astronomers detect polarized radio waves from a gamma-ray burst for the first time. Polarization signature reveals magnetic fields in explosions to be much more patchy and tangled than first thought. Combining the observations with data from X-ray and visible light telescopes is helping unravel the mysteries of the universe's most powerful explosions.
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.
When massive stars die at the end of their short lives, they light up the cosmos with bright, explosive bursts of light and material known as supernovae. A supernova event is incredibly energetic and intensely luminous -- so much so that it forms what looks like an especially bright new star that slowly fades away over time.
For 10 years, NASA's Fermi Gamma-ray Space Telescope has scanned the sky for gamma-ray bursts (GRBs), the universe's most luminous explosions. A new catalog of the highest-energy blasts provides scientists with fresh insights into how they work.
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.
