How fast is our universe expanding? The Hubble constant is one of the most critical numbers in cosmology because it tells us how fast the universe is expanding. There are different methods exist to measure this rate. However, determining this number’s accuracy is essential to understand better fundamental questions like…

Home News Science & Astronomy Astronomers have photographed a violent cosmic dance that began between two galaxies a billion years ago, pulling them into a collision that birthed a new chaotic galaxy.  At the heart of that giant collision-born galaxy are two supermassive black holes — each once at the…

Black holes, wormholes, entanglement, Einstein, mysterious islands and new science that sees how the inside of a black hole is secretly on the outside. Black holes have been a big problem in physics. For decades, scientists have been mystified about what happens to stuff that falls into a black hole. …

Recent theoretical and observational results have revealed new secrets about these shadowy objects, with deep implications for more than just black holes themselves By Clara Moskowitz By:Clara Moskowitz close Clara Moskowitzis Scientific American's senior editor covering space and physics.

These fun stories show progress from the scale of quantum effects to that of snakes and from Earth to the edge of the universe Credit: Scientific American, August 2022 If somebody yells, “Snake!” are you more likely to jump back in fright or say, “Ooh, where?” Fear of snakes (ophidiophobia)…

ESO’s Very Large Telescope (VLT) has imaged the result of a spectacular cosmic collision — the galaxy NGC 7727. This giant was born from the merger of two galaxies, an event that started around a billion years ago. At its centre lies the closest pair of supermassive black holes ever…
