Water is essential for life, but where does it come from? Read on and learn that a significant amount is inherited from the interstellar medium.
Spherical cows have a long and storied history in physics, but does this type of crude approximation lead to realistic conclusions in the case of star formation? The combination of large- and small- scale simulations tests this idea.
Can we find galaxies using the light emitted by their star forming regions? The authors of this paper explore a technique that would allow us to reach relatively unexplored epochs of the Universe.
Massive stars emit energetic radiation and expel strong winds that can disrupt their natal environments. New simulations show that these effects are important in the evolution of stellar nurseries and can account for some of the observed low efficiency of star formation.
In today’s “astrophysical classic”, we delve into the seminal paper behind the Kennicutt-Schmidt relation, the empirical correlation between the star formation rate and gas density.
Douglas Adams’ fictional Ford Prefect famously warned us of eddies in the spacetime continuum. Has the IBEX spacecraft now found evidence that they really exist?
There’s a strange sickle-shaped object in the Carina Nebula. The authors of this paper used observations at several different wavelengths to investigate the nature of this intriguing nebula, leading to some interesting discoveries and even more questions.
It’s big, it’s active, and it’s only 20 million lightyears away– it is the Whirlpool galaxy, and astronomers are getting a brand new view. Using the Plateau de Bure interferometer, this paper examines the gas in this nearby grand-design spiral galaxy on arcsecond scales, resolving for the first time its individual molecular clouds. What does this tell us about star formation in this galaxy? Stay tuned!
