Einstein’s general relativity theory is questioned but still stands for now

Black hole illustration (stock image). Credit: © Andrea Danti / Adobe Stock More than 100 years after Albert Einstein published his iconic theory of general relativity, it is beginning to fray at the edges, said Andrea Ghez, UCLA professor of physics and astronomy. Now, in the most comprehensive test of general relativity near the monstrous…

How humans have shaped dogs’ brains

Puppies of various dog breeds (stock image). Credit: © Rawpixel.com / Adobe Stock Dog brain structure varies across breeds and is correlated with specific behaviors, according to new research published in JNeurosci. These findings show how, by selectively breeding for certain behaviors, humans have shaped the brains of their best friends. Over several hundred years,…

Confirmation of toasty TESS planet leads to surprising find of promising world

This diagram shows the layout of the GJ 357 system. Planet d orbits within the star’s so-called habitable zone, the orbital region where liquid water can exist on a rocky planet’s surface. If it has a dense atmosphere, which will take future studies to determine, GJ 357 d could be warm enough to permit the…

Dead planets can ‘broadcast’ for up to a billion years

Planetary nebula with white dwarf illustration (stock image). Credit: © Peter Jurik / Adobe Stock Astronomers are planning to hunt for cores of exoplanets around white dwarf stars by 'tuning in' to the radio waves that they emit. In new research led by the University of Warwick, scientists have determined the best candidate white dwarfs…

Hubble uncovers a ‘heavy metal’ exoplanet shaped like a football

This artist's illustration shows an alien world that is losing magnesium and iron gas from its atmosphere. The observations represent the first time that so-called "heavy metals"—elements more massive than hydrogen and helium—have been detected escaping from a hot Jupiter, a large gaseous exoplanet orbiting very close to its star.The planet, known as WASP-121b, orbits…

Dark matter may be older than the Big Bang

Big Bang illustration (stock image). Credit: © Andrea Danti / Adobe Stock Dark matter, which researchers believe make up about 80% of the universe's mass, is one of the most elusive mysteries in modern physics. What exactly it is and how it came to be is a mystery, but a new Johns Hopkins University study…

Glitch in neutron star reveals its hidden secrets

Neutron star illustration (stock image). Credit: © dani3315 / Adobe Stock Neutron stars are not only the most dense objects in the Universe, but they rotate very fast and regularly. Until they don't. Occasionally these neutron stars start to spin faster, caused by portions of the inside of the star moving outwards. It's called a…
