ALMA Finds New Molecular Signposts in Starburst Galaxy
The ALMA radio telescope has detected more than 100 molecular species, including many indicative of different star formation and evolution processes, in a galaxy where stars are forming much more actively than in the Milky Way. This is far more molecules than were found in previous studies. Now the team will try to apply this knowledge to other galaxies.

Simulations of Europa Craters Suggest Thick Ice Crust
Sometimes planetary physics is like being in a snowball fight. Most people, if handed an already formed snowball, can use their experience and the feel of the ball to guess what kind of snow it is comprised of: wet and puffy, or dry and packable. Using nearly the same principles, planetary scientists have been able to study the structure of Europa, Jupiter’s icy moon.

Ancient Gas Outflow Suppressed Star Formation
Astronomers have found the earliest known example of a galaxy hosting an active supermassive black hole expelling large quantities of molecular gas. This outflow will suppress star formation in the galaxy. These results will help us to understand how black holes and galaxies have evolved together over the history of the Universe.

New Red Galaxies Turn Out to be Already Known Blue Galaxies
Not all discoveries turn out to be actual new discoveries. This was the case for the extremely red objects (EROs) found in James Webb Space Telescope (JWST) data. Analysis shows that they are very similar to blue-excess dust obscured galaxies (BluDOGs) already reported in Subaru Telescope data.
