TESS Spotted 3I/ATLAS Two Months Before It Was Discovered - It Was Even Active Then
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.
A New Theory of the Universe’s Origins Without Inflation
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.
Asteroid Bennu Is Like A Time Capsule From The Early Solar System
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.

GJ 1132 b Doesn't Have An Atmosphere, According To New JWST Data
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.
