Stream of local stars formed in another galaxy is evidence of The Milky Way’s violent history
A Vast Stream of Flowing Stars Is Evidence of The Milky Way’s Violent History Using data from the Gaia Milky Way mapping survey, astronomers have discovered a vast stream of stars that they believe are the remnants of a massive dwarf galaxy that got dragged into the galactic disc before being torn apart.…

Scientists spot flash of light from colliding black holes. But how?
Scientists spot flash of light from colliding black holes. But how? Scientists think they identified two black holes merging that produced a burst of light. Black holes aren’t supposed to make flashes of light. It’s right there in the name: black holes. Even when they slam into each, the massive objects are supposed to be…

Did Galaxies Grow from Quantum Static?
Did Galaxies Grow from Quantum Static? A new test could determine whether large-scale cosmic structures have microscopic origins Did Galaxies Grow from Quantum Static? Quantum fluctuations in the early universe may have seeded the formation of large cosmic structures, such as this galaxy cluster. Credit: NASA, ESA, Hubble and RELICS Some 13.8 billion…

CERN makes bold push to build €21-billion super-collider
CERN makes bold push to build €21-billion super-collider European particle-physics lab will pursue a 100-kilometre machine to uncover the Higgs boson’s secrets — but it doesn’t yet have the funds! The decision was unanimously endorsed by the CERN Council on 19 June, following the plan’s approval by an independent panel in March. Europe’s…

Hubble Has Looked Back in Time as Far as It Can And Still Can’t Find The First Stars
Hubble Has Looked Back in Time as Far as It Can And Still Can’t Find The First Stars Astronomers don’t know exactly when the first stars formed in the Universe because they haven’t been observed yet. And now, new observations from the Hubble Space Telescope suggest the first stars and galaxies may have formed…

Half the matter in the universe was missing – we found it hiding in the cosmos
Half the matter in the universe was missing – we found it hiding in the cosmos Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.
