The Wide Field Imager at the ESO’s La Silla Observatory in Chile has captured new images of two dramatic regions of star formation in the southern Milky Way, one of which features a Wolf–Rayet multiple star system.

New Evidence Explains How The 'Pillars Of Creation' Came Into Being
2014-06-27 06:48:02

The ‘Pillars of Creation’ is one of the most famous images made with the Hubble Space Telescope. It shows cooler interstellar gases being eroded by intense radiation and wind from nearby massive stars.

Supernova Progenitor Revealed
2014-05-22 06:28:27

For the first time ever, astronomers have directly confirmed that a rare and extremely massive type of star known as a Wolf-Rayet star died in a violent explosion known as a Type IIb supernova.

Snake Nebula
2014-02-26 12:49:25

Astronomers using the Smithsonian's Submillimeter Array telescope have imaged the most detailed look yet of stellar nurseries within the Snake nebula.

Sharpest Ever Image Of Prawn Nebula Unveiled
2013-09-18 10:42:57

Astronomers using the Very Large Telescope at the European Southern Observatory's Paranal Observatory in Chile have taken the sharpest image ever of the Prawn Nebula.

Hubble Views A Cosmic Caterpillar

This light-year-long knot of interstellar gas and dust resembles a caterpillar on its way to a feast.

NASA’s Swift Maps Magellanic Clouds With Ultraviolet
2013-06-04 07:38:12

Using NASA’s Swift satellite, astronomers have created the most detailed ultraviolet surveys to-date of the two closest major galaxies, the Large and Small Magellanic Clouds.

Most Massive Binary Candidate Identified
2013-04-17 04:52:37

A team of astronomers, led by Hugues Sana of the University of Amsterdam, has observed a binary star that potentially weighed 300 to 400 times the mass of our Sun at its birth.

Older Stars Help Baby Stars Grow Up To Be Massive
2013-03-28 08:55:25

Stars with ten times or more the mass of our Sun should not exist. They push away the gas they feed on as they grow, starving themselves for fuel. Astrophysicists have been struggling to understand how some stars are able to overcome this developmental hurdle.

Solar Winds Examined By XMM-Newton
2013-02-05 18:03:01

While solar wind is a common occurrence in our Solar System, a study of a new, more fierce wind has been completed using the European Space Agency's XMM-Newton space observatory.

Star -- A star is a self-gravitating sphere of plasma in hydrostatic equilibrium that generates energy in its interior through the process of nuclear fusion. Energy from this process radiates into space as electromagnetic radiation and neutrinos. Star formation and evolution As learned by star formation astronomers, stars are born in molecular clouds, regions of higher density of matter, and form by gravitational instability inside those clouds. High mass stars illuminate powerfully...
