A recent breakthrough in astronomy has illuminated the mysterious dynamics of a binary star system, HD 135344 AB, where a giant planet was discovered orbiting the primary star— a star that had ...

The Sun is very much a main sequence star, in the G-type category (G2V to be precise). It’s been fusing hydrogen for 4.6 billion years, but it still has almost three times as much as it has helium.

Early stages of star formation are now better understood, following an extensive millimeter-wave study of protostars, which are young stellar objects still deeply embedded in their parent ...

The only place that's likely to happen is at the very center of our galaxy. And, for a while, there was an excess of radiation coming from the galactic core that people thought might be due to dark ...

While our Sun is considered a main sequence star that is “alive” given its active fusion process that converts hydrogen into helium, white dwarf stars are considered “dead” stars as they have ...
