Earth and the moon may look very different today, but they formed under similar conditions in space. In fact, a dominant hypothesis says that the early Earth was hit by a Mars-sized object, and it was this giant impact that spun off material to form the moon. But unlike Earth, the moon lacks plate tectonics […]
When lasers were invented in the 1960s, they opened new avenues for scientific discovery and everyday applications, from scanners at the grocery store to corrective eye surgery. Conventional lasers control photons—individual particles of light—but over the past 20 years, scientists have invented lasers that control other fundamental particles, including phonons—individual particles of vibration or sound. […]
In quantum technologies, everything depends on the ability to detect the properties carried by a single photon. But in the real world, that photon of interest is often buried in a sea of unwanted light—a true “needle in a haystack” challenge that currently limits the deployment of many applications, including secure quantum communication, quantum sensors […]

Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner solar system, they consider it likely that 6–40% of this material must have come from the outer solar system, i.e., beyond Jupiter. For a long time, material from the outer solar system was considered necessary to […]
Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, silicon’s compatibility with existing chip technology and its long coherence times in silicon-based spin qubits make it a promising material for scalable quantum computing. A new study, published in Nature Nanotechnology, has demonstrated silicon’s use in a […]

Finding life beyond our solar system goes beyond measuring an exoplanet’s size, as rocky, Earth-sized worlds might not have the conditions for life as we know it. While exoplanets can be directly imaged by blocking their star’s glare, these images are fuzzy and lack resolution to provide enough details about the habitability. Therefore, astronomers are […]
Physicists have developed a new theoretical framework which unifies a wide array of seemingly unrelated “Mpemba effects”: counterintuitive cases where systems driven further from equilibrium relax faster than those closer to it. Reporting their results in Physical Review X, researchers led by John Goold at Trinity College Dublin show that both classical and quantum versions […]

Astronomers have discovered an exceptionally rare radio galaxy that has three distinct pairs of radio lobes. This system falls into a subpopulation of radio galaxies known as “triple-double” radio galaxies (TDRGs). Located nearly 7.5 billion light-years away, this unique system, cataloged as J022248−060934, is only the seventh known example of its kind. A paper outlining […]
The people who toiled night and day to put astronauts on the moon during Apollo are thrilled that NASA is finally going back. They just wish these Artemis moonshots had happened sooner while more of Apollo’s workforce was still alive.

Douglas Adams told us the answer to life, the universe and everything is 42. If only cosmology were so straightforward. Astronomers have been arguing for years about a number every bit as fundamental, and they still can’t agree on it.

NASA’s Apollo moonshots are a tough act to follow, even after all this time.
