Nearly half the stars in our galaxy are solitary like the sun. The other half comprises stars that circle other stars, in pairs and multiples, with orbits so tight that some stellar systems could fit ...
Astronomers have found stellar eggs containing baby stars around the center of the Milky Way galaxy. To make the discovery, the scientists used NSF's Atacama Large Millimeter/submillimeter Array (ALMA...
When the most massive stars die, they collapse under their own gravity and leave behind black holes. When stars that are a bit less massive die, they explode in supernovas and leave behind dense, dead...
An international team of astronomers used two of the most powerful radio telescopes in the world to create more than three hundred images of planet-forming disks around very young stars in the Orion C...
The International School for Young Astronomers on Stars and Exoplanets will be held in November 26th to December 9th, 2017 in Kunming, China, under the organization of Yunnan Observatories (YNOs) of C...
For the first time, scientists have directly detected gravitational waves -- ripples in space-time -- in addition to light from the spectacular collision of two neutron stars. This marks the first tim...
Two months ago, the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) notified astronomers around the world of the possible detection of gravitational waves from the merger of two ne...
Our solar system is teeming with simple carbon-based molecules, the basic building blocks of life. If the conditions are right, these simple molecules can go on to form more complex, biologically inte...
Imagine a planet like Jupiter zipping around its host star every day and a half, superheated to temperatures hotter than most stars and sporting a giant, glowing gas tail like a comet.That is what an ...
A newly discovered Jupiter-like world is so hot that it’s stretching the definition of the word “planet.”With a day-side temperature of 4,600 Kelvin (more than 7,800 degrees Fahrenheit), planet KELT-9...
New information gleaned from gravitational wave observations is helping scientists understand what happens when massive stars die and transform into black holes. Rochester Institute of Technology res...
The search for planets beyond our solar system is about to gain some new recruits.Today, a team that includes MIT and is led by the Carnegie Institution for Science has released the largest collection...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a tsunami of stars and gas that is crashing midway through the disk of a spiral galaxy known as IC 2163. This ...
Among the most striking objects in the universe are glittering, dense swarms of stars known as globular clusters. Astronomers had long thought globular clusters formed their millions of stars in bulk ...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found the clearest evidence yet that giant planets have recently formed around four young stars. These new worlds, each p...
