Michigan State University (MSU) researchers have discovered that one of the most important reactions in the universe can get a huge and unexpected boost inside exploding star – supernovae.

This finding also challenges ideas behind how some of the Earth’s heavy elements are made...

New approach to show how ghost-like neutrinos helped shape the Universe. Computer simulations have struggled to capture the impact of elusive particles called neutrinos on the formation and growth of the large-scale structure of the Universe. But now, a research team from Japan has developed a method that overcomes this hurdle.

In a study published this month in The Astrophysical Journal, researchers led by the University of Tsukuba present simulations that accurately depict the role of neutrinos in the evolution of the Universe.

Why are these simulations important? One key reason is that they can set constraints on a currently unknown quantity: the neutri...

There is no weather in space – but there is weathering: Celestial bodies are bombarded by high energy particles. On the Mars moon Phobos, the situation is complicated: It is hit by particles from the sun, but it is partly shielded by Mars. New experiments explain what is going on, in 2024 a space mission will reach Phobos and check the results.

Of course, there is no weather in our sense of the word in space — nevertheless, soil can also “weather” in the vacuum of space if it is constantly bombarded by high-energy particles, such as those emitted by the sun...

Using NASA’s SOFIA telescope, researchers have found CQ 4479, a galaxy which never had been closely studied before, to be generating new stars in spite of a luminous AGN at the galaxy’s center. Researchers from the University of Kansas have described a galaxy more than 5.25 billion light years away undergoing a rarely seen stage in its galactic lifecycle. Their findings recently were published in the Astrophysical Journal.

The galaxy, dubbed CQ 4479, shows characteristics that normally don’t coexist: an X-ray luminous active galactic nuclei (AGN) and a cold gas supply fueling high star formation rates.

“Massive galaxies, such as our own Milky Way, host a supermassive black hole at their hearts — these are black holes that grow by accreting interstellar gas onto themselves to bec...
