Meteorites Show That Our Solar System Formed in Less Than 200,000 Years
A long time ago — roughly 4.5 billion years — our sun and solar system formed over the short time span of 200,000 years. That…

NASA’s Nancy Grace Roman Space Telescope will detect vestiges of sound waves that once rippled through the primordial cosmic sea. According to new simulations, Roman’s…
New research indicates that limited resources on Earth’s satellites could cause crowding and competition as site selection, and extraction become a reality. An international team…
Researchers have developed a new theory for observing a quantum vacuum that could lead to new insights into the behavior of black holes. The Unruh…
Australian telescopes and European satellite combine to reveal unexpected motions among the Galaxy’s rarest objects. Theories on how the Milky Way formed are set to…
In 1838, Friedrich Wilhelm Bessel won the race to measure the first distance to a star other than our Sun via the trigonometric parallax –…
Astronomers using data from the ongoing VLA Sky Survey (VLASS) have found a number of distant galaxies with supermassive black holes at their cores that…
Scientists have discovered a rare object called the Blue Ring Nebula, a ring of hydrogen gas with a star at its center. The properties of…
Scientists working with data from the Sloan Digital Sky Surveys’ Apache Point Observatory Galactic Evolution Experiment (APOGEE) have discovered a “fossil galaxy” hidden in the…
A new study lead by GSI scientists and international colleagues investigates black-hole formation in neutron star mergers. Computer simulations show that the properties of dense…
Massive explosions of energy happening thousands of light-years from Earth may have left traces in our planet’s biology and geology, according to new research by…
The Blue Ring Nebula, which perplexed scientists for over a decade, appears to be the youngest known example of two stars merged into one. In…
Johns Hopkins University’s study of 10 billion years of microwaves reveals a warming predicted by dark matter theory. Who says you can’t get hotter with…
It’s one of the big cosmology debates: the universe is expanding, but how fast exactly? Two available measurements yield different results. Leiden physicist David Harvey…
In their paper published in Frontiers of Physics, Franco Vazza (astrophysicist at the University of Bologna) and Alberto Feletti (neurosurgeon at the University of Verona)…
By studying the site of a spectacular stellar explosion seen in April 2020, a Chalmers-led team of scientists have used four European radio telescopes to…
An international team of scientists has shown that glycine, the simplest amino acid and an important building block of life, can form under the harsh…
Light from distant galaxies reveals important information about the nature of the universe and allows scientists to develop high-precision models of the history, evolution, and…
