Evidence found for cloaked black hole in early universe
A group of astronomers, including Penn State scientists, has announced the likely discovery of a highly obscured black hole existing only 850 million years...
Earth’s last magnetic field reversal took far longer than once thought
Earth's magnetic field seems steady and true—reliable enough to navigate by.
Yet, largely hidden from daily life, the field drifts, waxes and wanes. The magnetic North...
Dark matter may be older than the big bang, study suggests
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...
Astronomers reveal true colors of evolving galactic beasts
Astronomers have identified a rare moment in the life of some of the universe's most energetic objects. Quasars were first observed 60 years ago,...
A whopping ‘squawkzilla’: Meet ‘Hercules’—the giant parrot that dwarfs its modern cousins
Australasian palaeontologists have discovered the world's largest parrot, standing up to 1m tall with a massive beak able to crack most food sources.
The new...
Astronomers discover vast ancient galaxies, which could shed light on dark matter
Astronomers have used the combined power of multiple astronomical observatories around the world and in space to discover a treasure trove of previously unknown...
Astrophysical shock phenomena reproduced in the laboratory
Vast interstellar events where clouds of charged matter hurtle into each other and spew out high-energy particles have now been reproduced in the lab...
Moonquakes tumble boulders, build lunar scarps
The Apollo Moon buggies weren't the only things rolling over the Moon's surface in the early 1970s.
New research has found that a strong moonquake...
Researchers uncover hidden topological insulator states in bismuth crystals
The search for better materials for computers and other electronic devices has focused on a group of materials known as "topological insulators" that have...
New insights into the origin of life
A famous experiment in 1953 showed that amino acids, the building blocks of proteins, could have formed spontaneously under the atmospheric conditions of early...
Dead planets can ‘broadcast’ for up to a billion years
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...
