Greenhouse gas concentrations increased by a record amount in 2024 as more carbon dioxide, methane and nitrous oxide became locked in Earth's atmosphere, a World Meteorological Organization report finds.
Researchers have discovered dozens of new methane seeps littering the ocean floor in the Ross Sea coastal region of Antarctica, raising concerns of an unknown positive climate feedback loop that could accelerate global warming.
Comets Lemmon and SWAN will be at their brightest just as the annual Orionid meteor shower produced by Halley's Comet reaches its peak.
Researchers have found a suspected clump of dark matter lurking within the luminous halo of a well-known "Einstein ring." The mysterious object, the smallest of its kind ever seen, could help shed light on the universe's missing matter.

Opinion Thousands of scientific papers are retracted every year because of fraudulent activity, with both authors and journals gaming a system to gain academic acclaim through deceit, dishonesty and false representation.
Opinion The pervasive spread of misinformation can be tracked to cognitive limitations, social influence and the global spread of online networks. Combatting it has become an "arms race" between truth and lies.
For the first time, physicists have simulated what objects moving near the speed of light would look like — an optical illusion called the Terrell-Penrose effect.
Planets that orbit white dwarf stars should be too hot to host alien life, theories suggest. But a new study accounting for Einstein's general relativity may rewrite that rule.
The 2025 Nobel Prize in Physics has been awarded to John Clarke, Michel H. Devoret and John M. Martinis "for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit."
Here's why you may start tearing up while slicing an onion.
Researchers used a new technique called algorithmic fault tolerance (AFT) to cut the time and computational cost of quantum error correction by up to 100 times in simulations of neutral-atom architecture.
