Fusion, which occurs when atomic nuclei combine to form new elements, is extremely powerful. All the stars in the universe, including the Sun, are nuclear furnaces fueled by fusion. Through fusion, stars are responsible for forming all the naturally occurring elements heavier than hydrogen and heliu

Discover how the James Webb Space Telescope will help us better understand solar system formation in this video from NASA. Images from the Hubble Space Telescope show star-forming regions within the Eagle nebula: visible light images show vast clouds of gas and dust, and infrared images provide a gl
A neutron star comes from a large star that has run out of fuel, and exploded as a supernova. First it becomes a radio pulsar and later becomes a magnetar. Or maybe it’s the other way around! NASA Science: http://science.nasa.gov/ Click here to see more videos: https://alugha.com/NASA
The early Universe was dark and cold until a few atoms of hydrogen and helium got together. A star was born. With the birth of the first stars, a fantastic chain of events occurred that enabled a diversity of elements and chemistry. Anything was possible. Website: https://www.bighistoryproject.com
In a new study, scientists at MIT, Harvard, Caltech and elsewhere report that they have observed a star swallowing a planet for the first time. They say Earth may suffer a similar fate in 5 billion years. (Learn more: http://news.mit.edu/2023/astronomers-spot-star-swallowing-planet-0503) Watch more
