we haveSagittarius A*, a beast weighing more than 4.5 million suns. Usually, these giant black holes are quiet and dormant, just sipping on whatever bits of gas or stars that wander too close. But occasionally, they feast on a much larger meal. When they do, that gas ...
How high-mass stars formAn infrared images of the W# region of the Perseus Arm of the Milky Way Galaxy is presented from the European Space Agency's Herschel Space Observatory, which shows star-formation regions where star-forming material converges.Fer...
During the process of star formation, a protostellar disk serves as a means of delivering material to the nascent “protostar” at its core. In the case of high-mass protostars that have already surpassed 8 times the mass of the Sun and continue to grow, it is hypothesized that instead ...
While religious views and historical traditions have a strong influence on funerary practices, so do societal, economic and ecological needs. As more people look into cremation as a viable funerary option, they might find it's not as mysterious as they thought....
Our Milky Way galaxy is home to various stars: from low-mass stars to high-mass stars, from neutron stars to multiple stars systems. They all have their unique paths of stellar evolution, influenced by their mass, surrounding gas and environment. ...

It's a staple of science fiction, restarting our dying star with some kind of atomic superbomb. Why is our sun running out of fuel, and what can we actually do to get it restarted? Stars die. Occasionally threatening the Earth and its civilization in a variety plot devices inscience fict...
All we have to do is figure out how to not move ourselves — since special relativity would ensure we'd be long destroyed before we reached high enough speed — but instead, move the space around us. Easy, right? One proposed idea involves a spaceship that could fold a space-time bubble...
