The European Space Agency-led Solar Orbiter mission has split the flood of energetic particles flung out into space from the Sun into two groups, tracing each back to a different kind of outburst from our star.

Sometimes even the sky surprises you.

The EPA fired five agency employees who signed a June declaration decrying moves that contradict science and undermine public health, alongside four more served removal notices

One of the advantages of having so many telescopes watching large parts of the sky is that, if astronomers find something interesting, there are probably images of it from before it was officially discovered sitting in the data archives of other satellites that noone thought to look at. That has certainly been the case for our newest interstellar visitor, 3I/ATLAS, which, though discovered in early July, had been visible on other telescopes as early as May. We previously reported on Vera Rubin’s detection of 3I/ATLAS well before it was officially found, and now a new paper has found the interstellar object in TESS’s data going back to early May - and it looks like it may have been “active” around that time.

How exactly did the universe start and how did these processes determine its formation and evolution? This is what a recent study published in Physical Review Research hopes to address as a team of researchers from Spain and Italy proposed a new model for the events that transpired immediately after the birth of the universe. This study has the potential to challenge longstanding theories regarding the exact processes that occurred at the beginning of the universe, along with how these processes have governed the formation and evolution of the universe.

New research based on samples from asteroid Bennu show that the asteroid contains materials from throughout the Solar System. Some of its materials are from even more distant realms: the asteroid contains stardust from stars that existed long before our Solar System did.
