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.

Revolutionary Model Reveals How Real Universe Structure Affects Cosmic Evolution
For nearly a century, cosmologists have relied on a simplified model of the universe that treats matter as uniform particles that don't interact with each other. While this approach helped scientists understand the Big Bang and the expansion of space, it ignores a fundamental reality, that our universe is anything but uniform. Stars cluster into galaxies, matter collapses into black holes, and vast empty voids stretch across space, all constantly interacting through gravity and other forces.
A dead 'sun' forms building blocks of exoplanets in new JWST Butterfly Nebula image
The Butterfly Nebula, which is a planetary nebula resulting from the death of a sun-like star, has been caught creating large dust grains that could form planets.

SpaceX Falcon 9 rocket launches Starlink satellites on record-breaking 30th flight
A SpaceX Falcon 9 rocket flew for a record 30th time early Thursday morning (Aug. 28), sending 28 Starlink satellites to orbit from Florida.
Izaña-2 joins the laser game to track space debris
Video: 00:09:30
In Tenerife, Spain, stands a unique duo: ESA’s Izaña-1 and Izaña-2 laser-ranging stations. Together, they form an optical technology testbed of the European Space Agency that takes the monitoring of space debris and satellites to a new level while maturing new technologies for commercialisation.
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
The ambitious mission to retrieve samples from asteroid Bennu and return them to Earth is paying off. Just as scientists had hoped, the asteroid is revealing details about the early days in our Solar System. More than just a simple space rock, research is revealing that Bennu contains not only material from the Solar System, but material from beyond our system.
