Earlier this year, the Dark Energy Spectroscopic Instrument (DESI) completed observations that mapped 47 million galaxies across 11 billion light-years, allowing astronomers to better evaluate the large-scale structure of the visible universe. After studying these data, astronome

A new study debunks a recent claim that astronomers may have detected a lunar-mass primordial black hole. In a reanalysis of observations from the Dark Energy Camera (DECam), researchers found that the star nicknamed "Phoebe" was simply doing something ordinary that many stars do

A warm start to winter is part of a global trend of extreme and unseasonable temperatures caused by global heatingMany parts of Australia have already broken early winter maximum and minimum temperature records.In southern Australia, Sydney and Melbourne had their warmest-ever st

Influencers who frequently switch between emotions during livestreams may attract more likes and comments, but they are likely to sell fewer products, according to new research from QUT. Published in the Journal of the Academy of Marketing Science, the research analyzed more than

Astronomers have used the European Southern Observatory's Very Large Telescope (ESO's VLT) to study the composition of 3I/ATLAS, the brightest interstellar object ever seen, in detail. By measuring specific chemical fingerprints—the first observations of this kind for a comet tha

Cities are often described as "heat islands," with media reports warning that some neighborhoods can be 20° F (7° C) hotter than others. But those temperatures are often based on satellite data rather than the conditions people actually experience, due to the dearth of near-surfa

Citizen scientists have helped researchers solve a long-standing mystery about how parental care evolved in harvestmen. Using photos and observations from iNaturalist, scientists more than doubled the known cases of egg-guarding behavior and discovered that maternal and paternal

More than a century after Albert Einstein first transformed our understanding of gravity, his general theory of relativity continues to withstand ever more demanding experimental tests. Now, an international team led by Ignazio Ciufolini at the Chinese Academy of Sciences has car

This summer, Subaru Telescope will welcome a new near-infrared spectrograph, NINJA, for its first on-sky engineering observations. NINJA is a new spectrograph designed for time-critical observations of rapidly evolving cosmic events, such as the electromagnetic counterparts of gr

When neutron stars merge, they create a powerful explosion called a kilonova that flings out neutron-rich material, some of which decays into heavy elements through a process called the r-process. Recent observations of kilonovae revealed unexpected signatures that could not be e

At Archbold Biological Station, decades of field observations are helping scientists better understand one of nature's oldest relationship strategies: long-term monogamy.

Astronomers have made a series of landmark observations of one of the universe's most violent events. Using the U.S. National Science Foundation Very Large Array (NSF VLA) radio telescope, which is operated by the U.S. National Science Foundation National Radio Astronomy Observat
