Stars in our Milky Way galaxy move in a more or less orderly way. But a star that moves differently from the general stream of stars is known as a runaway star.
The James Webb Space Telescope has captured images of the Tarantula Nebula in the Large Magellanic Cloud, revealing stellar nurseries and protostars.
Glowing brightly about 160,000 light-years away, the Tarantula Nebula is the most spectacular feature of the Large Magellanic Cloud, one of our Milky Way's satellite galaxies.
The Herschel space observatory has exhausted its supply of liquid helium coolant, essential to cool the observatory's instruments.
Astronomers found four monster stars, one more than 300 times the mass of our sun. They were created from the merger of lighter stars in tight binary systems.
The constellations Dorado and Mensa are deep in southern skies. Between them, stretching across the border, lies the Large Magellanic Cloud.
Launched last April, TESS is successor to the Kepler mission, which discovered a substantial fraction of all known exoplanets orbiting distant suns. This 1st-light image from TESS is cause for celebration. Ahoy! New worlds ahead!
