Astronomers found a number of stellar eggs containing baby stars around the center of the Milky Way using the Atacama Large Millimeter/submillimeter Array (ALMA). Previous studies had suggested that the environment there is too harsh to form stars. These findings indicate that star formation is more resilient than researchers thought.

Stars form in stellar eggs, cosmic clouds of gas and dust which collapse due to gravity. If something interferes with the gravity driven contraction, star formation will be suppressed...

Astronomers are now in a better position to interpret observations of supernova remnants thanks to computer simulations of these cataclysmic events by RIKEN astrophysicists.

When certain types of stars die, they go out in a blaze of glory—an incredibly powerful explosion known as a supernova. One of the most common forms of supernova, typeIa, starts with a dense white dwarf star that has burned up its hydrogen fuel...

The very first moments of the Universe can be reconstructed mathematically even though they cannot be observed directly. Physicists from the Universities of Göttingen and Auckland (New Zealand) have greatly improved the ability of complex computer simulations to describe this early epoch...

Scientists estimate that dark matter and dark energy together are some 95% of the gravitational material in the universe while the remaining 5% is baryonic matter, which is the “normal” matter composing stars, planets and living beings. However, for decades, almost one-half of this matter has not been found. Now, using a new technique, a team including researchers from the Instituto de Astrofísica de Canarias (IAC) has shown that this “missing” baryonic matter fills the space between galaxies as hot, low-density gas...
