V4641 Sagittarii is a system about 20,000 light-years from Earth. Astronomers have now detected photons from V4641 Sagittarii carrying energies of up to a staggering 200 teraelectronvolts (TeV).
A huge ancient Mayan city that may have housed between 30,000 and 50,000 people at its peak between 750 and 850 AD was discovered in Mexico by accident thanks to Lidar technology.
Greenhouse gas levels surged to a new record in 2023, committing the planet to rising temperatures for many years to come. CO2 is accumulating in the atmosphere faster than any time experienced during human existence.
In 2022, U.S. high school students Calcea Johnson and Ne'Kiya Jackson astonished teachers when they discovered a new way to prove Pythagoras' theorem using trigonometry after entering a competition at their local high school.
Neutron stars with a penchant for extreme spinning could be churning out one of the most sought-after particles in the Universe.
In this system, called V404 Cygni, the black hole is consuming a small star that is spiraling in very close and fast while a newfound third star circles the black hole from much farther away.
The discovery of a new, complex molecule (1-cyanopyrene) in space challenges expectations about where the building blocks for carbon are found and how they evolve.
The streaking Comet C/2024 S1 (ATLAS) has met a dramatic end, disintegrating as it approached its closest point to the sun this week.
An observatory high in the mountains of Mexico has recorded repeated emission of some of the highest-energy gamma rays ever recorded from a single point close to the galactic center.
For most of our evolutionary history, human activity has been linked to daylight. Technology has liberated us from these ancient sleep-wake cycles, but there is evidence sunlight has left and continues to leave its mark.
A recent study has found that seafood mislabelling is running rampant in Calgary, and that certain product names are more likely to hide species of conservation concern.
Some 3.26 billion years ago a giant rock between 50 and 200 times the size of the Chicxulub dino-killer smacked into our planet. The result of this impact may have churned up nutrients that gave a select few early microbes a boost.
Any advance in laser tech has huge potential across a whole range of fields and we just got a big one: ultra-short laser pulses of up to 100 megawatts, the most powerful of their type ever produced from a human-made system.
One of the great mysteries of the Universe is where all the metal actually comes from.
Resaerchers found that a specific fungus can recognize shapes, and communicate information about their surroundings throughout their network.
