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.

What about the middle stages? The march from single-celled organisms doing their single-celled thing to intelligent creatures that can wield tools and leave feedback reviews about them?

Astronomers sometimes find conflicting data when trying to answer a question. This is a normal part of the scientific process, and it simply means that more data is needed to prove or disprove the theory they are trying to test. One prominent example of conflicting data in recent exoplanet research was that of planet GJ 1132 b, which either had or didn’t have an atmosphere, depending on which data set was being used. A new paper from researchers using more observational time on the James Webb Space Telescope (JWST) can now definitively say that, most likely, GJ 1132 b doesn’t have an atmosphere - and that finding has wider implications for exoplanet research more generally.

What can parabolic flights teach scientists and engineers about electrolyzers and how the latter can help advance human missions to the Moon and Mars? This is the goal of a recent grant awarded to the Mars Atmospheric Reactor for Synthesis of Consumables (MARS-C) project, which is sponsored by the Southwest Research Institute (SwRI) and The University of Texas at San Antonio (UTSA). The $500,000 award for this research is part of NASA’s TechLeap Prize program with the goal of testing experimental electrolyzer technology that can be used for future missions.

The early Universe continues to spring surprises on astronomers. In a recent study of dim, distant objects, astronomers at the University of Missouri found at least 300 of them that look way too bright. That means they're forming stars much earlier than expected, or something else is going on. Whatever it is could affect our understanding of events in the infant cosmos.

After a string of setbacks, SpaceX executed the most successful flight test of its Starship launch system to date, featuring a first-of-its-kind payload deployment and a thrilling Indian Ocean splashdown.

Sometimes in science a negative result is just as important as a positive one. And sometimes data artifacts get the better of even the best space observatories. Both of those ideas seem to hold true for the James Webb Space Telescope’s recent observation of Epsilon Eridani, one of our nearest stars, and one that has decades worth of debate about whether there is a planet orbiting it or not. Unfortunately, while JWST’s NIRCam did find some interesting features, they were too close to a noise source in the telescope's instruments to be definitively labeled a “planet”. Their results were recently published on arXiv, and while it may sound disappointing, this type of work is exactly how science progresses.
