One of the Most Massive Black Holes in the Universe Lurks at the Center of the Cosmic Horsehoe

This figure from the research shows the relationship between the SMBH mass and the host effective
velocity dispersion. The black solid line represents the relation from previous research in 2016, with dashed and dotted lines showing the 1 sigma and 3 sigma scatter, respectively. Horseshoe is labelled and clearly deviates from established relationship. The other galaxies labelled nearby also contain UMBHs that deviate significantly. Image Credit: Melo-Carneiro et al. 2025.

In 2007, astronomers discovered the Cosmic Horseshoe, a gravitationally lensed system of galaxies about five-and-a-half billion light-years away. The foreground galaxy’s mass magnifies and distorts the image of a distant background galaxy whose light has travelled for billions of years before reaching us. The foreground and background galaxies are in such perfect alignment that they … Read more

Mysterious fast radio burst traced back to massive ‘cosmic graveyard’ of ancient stars

Astronomers have been forced to reassess the origins of mysterious, rapid radio wave blasts called “fast radio bursts” (FRBs). This rethink was brought about by an FRB first detected last year, which has been traced back to the “cosmic graveyard” of a massive “dead” galaxy filled with ancient stars located 2 billion light-years from Earth. … Read more

Ancient lizard traps are ecologically important habitat

Across south-west Australia, Aboriginal peoples have long built lizard traps by propping up rocks on granite outcrops. Now, it’s been found that these traps are not just culturally important but ecologically important too, providing reptiles with habitat and vital shade. “Granite outcrops are ancient, biodiverse, and culturally significant ecosystems that are at risk from contemporary … Read more
