(Phys.org)—Astronomers have spotted a star-forming ring around a distant star Kappa Ori, located at the south-eastern corner of the constellation of Orion. The star, also known as Saiph, is a supergiant with a mass of approximately ...
The NASA/ESA Hubble Space Telescope offers a multitude of spectacular images of celestial objects and a huge amount of scientific data helpful for astronomers. A team of scientists from UK and Sweden has recently made use ...
Eta Carinae, the most luminous and massive stellar system within 10,000 light-years, is best known for an enormous eruption seen in the mid-19th century that hurled at least 10 times the sun's mass into space. This expanding ...
