This Saber-Tooth Predator Was Likely One of The First True Carnivores

If you’ve ever lived with a cat, you’ve probably received a painful chomp from your beloved furball’s pointy canines at least once. But 42 million years ago, your kitty’s teeth would have looked very different: Evolution was only just honing the teeth of cat-like animals to a deadly sharp tip for piercing and shredding flesh. … Read more

Supermassive black holes: Characteristics and formation

Only a handful of supermassive black holes have been confirmed by scientists, but the universe could be filled with billions of these gravitational giants.  Theoretically, if you compress a sufficient amount of matter into a small enough space, it will create such a powerful gravitational field that nothing — not even light — can escape … Read more

Mysterious globular clusters could unlock the secrets of galaxy formation

Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of “Ask a Spaceman” and “Space Radio,” and author of “How to Die in Space.” Globular clusters are like astronomical coelacanths — mysterious living fossils. These densely packed collections of ancient stars may hold the ultimate secrets to the formation of … Read more

This Weirdly Tilted Black Hole Could Upend Our Understanding of How They Form

Black holes could make a strong case for being the most fascinating phenomena in the whole Universe, and scientists are constantly discovering more about the way that they work and behave – including how they’re created in the first place.   Now, a new study of an unusually misaligned one some 10,000 light-years away from … Read more

Strangely tilted black hole challenges formation theories

A tilted black hole spinning around a misaligned axis has been discovered in our galaxy, challenging theories of black hole formation. The black hole and its companion star form a system called MAXI J1820+070, which lies some 10,000 light-years away from Earth. The system was first spotted by NASA’s Chandra X-ray Observatory in 2018. But … Read more

Giant galactic bubble is driving star formation, new study finds

This visualization shows the Local Bubble with star formation happening on its surface. (Image credit: Leah Hustak (STScI)) Earth is surrounded by a vast bubble about 1,000 light-years wide whose borders drive the formation of all nearby young stars, a new study finds. For decades, astronomers have known the solar system lies within the so-called … Read more

Star formation: Watch the best ever simulation of a cosmic cloud

A computer simulation tracks 9 million years of evolution within a stellar nursery – also known as a giant molecular cloud – in which stars are born Space 11 January 2022 By Chen Ly The most detailed simulations to date of giant molecular clouds (GMCs) hint that we may need to rethink our understanding of … Read more

Exoplanets: Small Jupiter-like worlds hint we need to rethink gas giant formation

We thought young gas giant planets would be large and low-density, but the gas giants around a star that is just 20 million years old don’t fit this model Space 2 December 2021 By Chen Ly An artist’s impression of a Jupiter-like exoplanet Alexandr Yurtchenko/Alamy Two Jupiter-like planets that orbit a young star are much … Read more
