Scientists studying a nearby protostar have detected the presence of water in its circumstellar disk. The new observations made with the Atacama Large Millimeter/submillimeter Array (ALMA) mark the first detection of water being inherited into a protoplanetary disk without significant changes to its composition. These results further suggest that the water in our solar system formed billions of years before the sun. The new observations are published today in Nature.

V883 Orionis is a protostar located roughly 1,305 light-years from Earth in the constellation Orion. The new observations of this protostar have helped scientists to find a probable link between the water in the interstellar medium and the water in our solar system by confirming they have similar composition.

Their popularity makes celebrities easy to spot. Strangers, however, can also get mistaken for celebrities, resulting in cases of false “celebrity sightings.” In attempting to explain the contradiction, a University of California, Riverside, study reports that celebrity faces are remembered more precisely but less accurately.

Precision, in this context, refers to how memories for a particular face resemble each other over repeated memory retrievals, which can be likened to the clustering of arrows on a target in archery. Accuracy measures how remembered faces resemble newly encountered faces—or the deviation from the target in archery.

“What our findings say is that people might accept errors by misidentifying someone as a celebrity in the interest of securing a ‘celebrity sighting,’” said Weiwei Zhang, an associate professor of psychology, who led the study that appears in the journal Psychonomic Bulletin & Review. “Our study explains why people are good and bad at spotting celebrities and highlights the importance of assessing both memory imprecision and bias in memory performance.”

A recent study suggests most solar systems start with a supply of water that formed in interstellar space.

FallenKingdomReads’ list of 7 Hard Science Fiction Books That Will Make You Smarter.

Hard science fiction is a subgenre of science fiction that prioritizes scientific accuracy and explores scientific concepts in depth. These books often require a solid understanding of scientific principles and can be a great way to learn about complex scientific concepts in an engaging and accessible way.

Here are seven hard science fiction books that will make you smarter.

Reverse the aging process and live decades longer? Transfer your brain onto a database and achieve digital immortality? Humans one day may have such options.

Scientists have discovered a new material that could be set to change the entire world. Researchers say they have created a superconducting material that works at both a temperature and a pressure low enough to actually use it in practical situations. It reaches a breakthrough that scientists have been chasing for more than a century, in making a material that is able to transmit electricity without resistance, and pass magnetic fields around the material.

Researchers challenge their own assumptions to improve sea-level rise predictions.

Microsoft revealed an AI-powered Bing chatbot in February, dubbing it “the new Bing.” But what can you actually do with the new Bing, and where does it fall short?

The new Bing is impressive for an automated tool, as it can not only answer questions in full sentences (or longer paragraphs), but it can also draw information from recent web results. The web features give it an edge over ChatGPT, which has limited knowledge of current events and facts, but it still has problems providing factual answers or helpful responses. That significantly affects its usefulness as a tool, though Bing’s ability to cite sources can help you double-check its responses.
