Continents on Ancient Earth Were Created by Giant Meteorite Impacts, Scientists Find

Continents on Ancient Earth Were Created by Giant Meteorite Impacts, Scientists Find

To date, Earth is the only planet we know of that has continents. Exactly how they formed and evolved is unclear, but we do know – because the edges of continents thousands of miles apart match up – that, at one time long ago, Earth’s landmass was concentrated in one big supercontinent. Since that’s not … Read more

Unexpected Solar Wind Stream Hits Earth at 372 Miles Per Second

Unexpected Solar Wind Stream Hits Earth at 372 Miles Per Second

On Sunday, Earth’s magnetic field was pelted by a solar wind stream reaching velocities of more than 600 kilometers (372 miles) per second. While that’s nothing too alarming – solar storms often pummel our planet triggering spectacular auroras – what is weird is that this storm was totally unexpected. “This event was not in the … Read more

The Universe Could ‘Bounce’ For Eternity. But It Still Had to Start Somewhere

The Universe Could 'Bounce' For Eternity.  But It Still Had to Start Somewhere

From the smallest bacterium to the greatest galaxy, death looms on the horizon; even if, in cosmic terms, the time scales are too large for us to truly comprehend. Eventually, even the Universe itself should come to an end – when the last light winks out, and the cold, dense lumps of dead stars are … Read more

These Dwarf Galaxies Seem to Be Devoid of Dark Matter, And It Doesn’t Make Sense

These Dwarf Galaxies Seem to Be Devoid of Dark Matter, And It Doesn't Make Sense

Ask astronomers about dark matter and one of the things they talk about is that this invisible, mysterious ‘stuff’ permeates the universe. In particular, it exists in halos surrounding most galaxies. The mass of the halo exerts a strong gravitational influence on the galaxy itself, as well as on others in the neighborhood. That’s pretty … Read more

Water Can Spontaneously Form Hydrogen Peroxide, And We Finally Understand Why

Water Can Spontaneously Form Hydrogen Peroxide, And We Finally Understand Why

Since being plunged into a global pandemic, we’re probably far more aware of being surrounded by microdroplets of water. In humid air or expelled by a cough, sneeze or talking, these droplets can carry tiny particles with them, from pollution to viruses like the flu. Back in 2019, the basic chemistry of these motes of … Read more

Scientists Glimpse The Earliest Dark Matter Ever Observed in The Universe

Scientists Glimpse The Earliest Dark Matter Ever Observed in The Universe

What little we know of dark matter comes from calculations based on the glow of surrounding galaxies. The further away we look, however, the dimmer that starlight gets, making it harder to see the subtle influence of this most mysterious of forces. Now a collaboration between astronomers from Japan and the US has found a … Read more

Incredible New Footage Captures Two Stars Colliding Like We’ve Never Seen Before

Incredible New Footage Captures Two Stars Colliding Like We've Never Seen Before

The aftermath of an epic collision involving at least one neutron star has been captured for the first time in the millimeter range of radio frequency wavelengths. The result is a recording of a short-duration gamma-ray burst – one of the most energetic ever observed, and one of the brightest lingering afterglows we’ve ever seen. … Read more

Physicists Finally Measure a Long Theorized Molecule Made From Light And Matter

Physicists Finally Measure a Long Theorized Molecule Made From Light And Matter

Physicists have just caught light acting the part of ‘glue’ between atoms, in a kind of loosely bonded molecule. “We have succeeded for the first time in polarizing several atoms together in a controlled way, creating a measurable attractive force between them,” says University of Innsbruck physicist Matthias Sonnleitner. Atoms connect to form molecules in … Read more

Cosmic Buckyballs Could Be The Source of Mysterious Infrared Light

Cosmic Buckyballs Could Be The Source of Mysterious Infrared Light

Scientists may have just tracked down the source of some mysterious infrared glows detected emanating from stars and clouds of interstellar dust and gas. These Unidentified Infrared Emission (UIE) bands have baffled scientists for decades; according to a theoretical new work, at least some of these bands can be produced by highly ionized buckminsterfullerene, more … Read more
