The discovery of a millisecond pulsar in a triple system with two white dwarfs gives astronomers the most precise tool yet for studying the gravitational three-body problem. In addition, the nature of the stars and their interactions may give an unprecedented clue that points toward a new theory of gravity compatible, unlike general relativity, with quantum theory.
Recent studies with the Karl G. Jansky Very Large Array add strong, new evidence to the theory that binary stars form when the disk of gas and dust orbiting one young star gravitationally fragments, forming a second young star.
A team of scientists led by researchers in the Department of Astronomy and Astrophysics at the University of Chicago report they have definitively characterized the atmosphere of a super-Earth class planet orbiting another star for the first time.
The completion of the 30-day Lunar Laser Communication Demonstration or LLCD mission has revealed that the possibility of expanding broadband capabilities in space using laser communications is as bright as expected.
New research using data from NASA's Van Allen Probes mission helps resolve decades of scientific uncertainty over the origin of ultra-relativistic electrons in Earth's near space environment, and is likely to influence our understanding of planetary magnetospheres throughout the universe.
Massive stars present an intriguing mystery: how do they grow so large when the vast majority of stars in the Milky Way are considerably smaller? To find the answer, astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) telescope to survey the cores of some of the darkest, coldest, and densest clouds in our Galaxy to search for the telltale signs of star formation.
Scientists developed the 'Loss of the Night app' to quantify the illumination of the night sky caused by artificial light. The app, originally available in only German and English, has now been expanded to support 11 languages in order to get data from as many regions as possible.
Astronomers affiliated with the Supernova Legacy Survey have discovered two of the brightest and most distant supernovae ever recorded, 10 billion light-years away and a hundred times more luminous than a normal supernova.
This festive NASA Hubble Space Telescope image resembles a holiday wreath made of sparkling lights. The bright southern hemisphere star RS Puppis, at the center of the image, is swaddled in a gossamer cocoon of reflective dust illuminated by the glittering star. The super star is ten times more massive than our Sun and 200 times larger.
Was Einstein right? The European Research Council (ERC) has awarded 14 Million Euros to a team of European astrophysicists to construct the first accurate image of a black hole. The team will test the predictions of current theories of gravity, including Einstein's theory of General Relativity.
