The Big Bang may be the result of a 'bounce' inside a black hole. (Naeblys/Getty Images)The Big Bang is often described as the explosive moment that gave rise to the Universe – a singular point where space, time, and matter came into existence.But what if that wasn’t truly the beginning? What if our Universe originated...

Archival Chandra image of ACT-CL J0329. Credit: Sikhosana et al., 2024.A global team of astronomers conducted radio observations of the large galaxy cluster ACT-CL J0329.2-2330, uncovering a new radio halo within the cluster. The discovery was detailed in a research paper published on April 5 on the pre-print server arXiv.In fact, radio halos are...
In the realm of galaxies, our minds often conjure images of luminous spiral formations teeming with stars and cosmic gases. However, a distinct category known as low-surface-brightness galaxies challenges this conventional perception. These galaxies, characterized by sparse stars and unconventional appearances, typically harbor more dark matter and predominantly consist of gas, with few discernible...
Sagittarius A*, the black hole at the center of the Milky Way galaxyEHT Collaboration/CCA4.0Examining the stars in the night sky, it's unlikely you'd distinguish one as foreign. However, astronomers have identified a star near the supermassive black hole at the Milky Way's center, suggesting it originated in a smaller galaxy consumed by ours.Among...
