Herschel discovers some of the youngest stars ever seen
(Phys.org) —Astronomers have found some of the youngest stars ever seen, thanks to the Herschel space observatory, a European Space Agency mission with important NASA contributions.
Studying the 'mountains' and 'starquakes' that develop on neutron stars
Milky Way's biggest star may have had a different beginning
The current theory of star formation has a problem: it cannot make big stars.
Large water reservoirs at the dawn of stellar birth
(Phys.org)—ESA's Herschel space observatory has discovered enough water vapour to fill Earth's oceans more than 2000 times over, in a gas and dust cloud that is on the verge of collapsing into a new Sun-like ...
Explainer: What are stars?
Twinkle, twinkle, little star, how I wonder what you are.
Massive Stars Near the Galactic Center
The Central Molecular Zone (CMZ) of our galaxy is a giant complex of molecular gas and dust situated in the innermost 700 light-years of the Milky Way. Although the galaxy is over 100,000 light-years in size, ...
A new class of dim supernovae
The colossal stellar explosions called supernovae come in many kinds and flavours. Some of them are produced when a massive star reaches the end of its life in a sudden gravitational collapse. Astronomers ...
Cyanoacetylene in IC 342
Star formation is an incredible process, but also notoriously difficult to trace. The reason is that the main constituent of stars, hydrogen, looks about the same well before a gravitational collapse begins, ...
Seeking the earliest galaxies with cosmic telescopes
(Phys.org)—With a recent NSF award, UA scientists will use galaxy clusters as astronomical lenses to peer farther into the depths of space than any manmade telescope is capable of viewing - to the time ...
