Black Hole

Imagine every massive galaxy as a grand cosmic city, and at its heart, lurking in the shadows, is a gravitational monarch: a supermassive black hole (SMBH). These invisible titans don’t just sit idly; they co-evolve with their galaxies, shaping their growth like silent architects over billions of years. In elliptical…

Since its launch in late 2021, the James Webb Space Telescope (JWST) has been glimpsing some of the earliest epochs of cosmic time. Its observations have stretched cosmologists' timelines of when galaxies may have first started to form. And now some of the telescope’s farthest observations yet have revealed sources…

Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two black holes yet observed, resulting in a new black hole that is 225 times more massive than our Sun. The results were presented at the Edoardo Amaldi Conference on Gravitational…

Gravitational waves —ripples in space-time caused by violent cosmic events—travel at the speed of light in every direction, eventually fading out like ripples in water. But some events are so destructive and extreme that they create disturbances in spacetime more like powerful waves than small ripples, with enough energy to…

We've officially made it to the end of Playdate Season Two, and what a season it's been. Despite having half the number of titles as Season One, this latest round of weekly game releases has made a much stronger impression (on me, at least). If nothing else, it's just been…

Scientists have observed a new type of black hole that is too heavy to have been born from a star but still too slim to act as an anchor for an entire galaxy. These black holes are being being referred to as “lite” intermediate-mass black holes (IMBH), and they’re extremely…

Forty years ago an amateur Scottish paleontologist named Stan Wood made a fascinating discovery, uncovering Westlothiana lizziae , nicknamed “Lizzie.” The ancient salamander filled a niche that geologists had been after for years, marking the transition of the first animals from water to land. The earliest life began with the…

To fit with astronomical observations of…
