Anyone can become an asteroid hunter thanks to a new program launched by astronomers at the University of Arizona Lunar and Planetary Laboratory. As part of the Catalina Sky Survey, the scientists created an online portal that opens their mission—t.....»»
Billion-light-year-wide "bubble of galaxies" discovered
Astronomers have discovered the first "bubble of galaxies," an almost unimaginably huge cosmic structure thought to be a fossilized remnant from just after the Big Bang sitting in our galactic backyard......»»
Small prey compelled prehistoric humans to produce appropriate hunting weapons and improve their cognitive abilities
A new study from the Department of Archaeology at Tel Aviv University found that the extinction of large prey, upon which human nutrition had been based, compelled prehistoric humans to develop improved weapons for hunting small prey, thereby driving.....»»

Astronomers report the discovery of a new massive and quiescent galaxy at a high redshift. The galaxy, which received designation COSMOS-1047519, was detected using the Keck I telescope. The finding was detailed in a paper published August 29 on the.....»»
Researchers searching for the habitat of a threatened fish first seen in Southeast Asian markets
A multi-national research team from Indonesia, Australia, and the United States, are hunting to find the home of one of the world's most endangered fish, the Clown Wedgefish, a fish so elusive that it has only ever been recorded at fish markets......»»
Hunting for supermassive black holes in the early universe
Supermassive black holes (SMBHs)—black holes with masses exceeding a million times that of the sun—are known to prevail in the universe today. However, it is not clear yet when, where, and how they formed during the 13.8 billion years of cosmic h.....»»
Research sheds more light on the accretion history of EX Lupi
An international team of astronomers has investigated EX Lupi—a young T-Tauri star in the constellation of Lupus and an archetype of EXor stars. The study, presented in a paper published August 23 on the pre-print server arXiv, provided important i.....»»
European Southern Observatory telescopes help unravel pulsar puzzle
With a remarkable observational campaign that involved 12 telescopes both on the ground and in space, including three European Southern Observatory (ESO) facilities, astronomers have uncovered the strange behavior of a pulsar, a super-fast-spinning d.....»»
New giant planet shows evidence of possible planetary collisions
A Neptune-sized planet denser than steel has been discovered by an international team of astronomers, who believe its composition could be the result of a giant planetary clash......»»
Dense Neptune-sized exoplanet discovered with TESS

In the (convection) zone: Astronomers eavesdrop on stars’ innate “twinkle”
"Convection within stars is similar to the process that fuels thunderstorms." Visualization of "Twinkle, Twinkle, Little Star" played through three sizes of massive stars. Credit: Northwestern University. Science 101 tells us that t.....»»
Caroline Herschel was the first female astronomer, but she still lacks name recognition two centuries later
Caroline Herschel, the first professional female astronomer, made contributions to astronomy that are still important to the field today. But even many astronomers may not recognize her name......»»
A giant black hole destroys a massive star
Astronomers have made a thorough forensic study of a star that was torn apart when it ventured too close to a giant black hole and then had its insides tossed out into space......»»
Astronomers discover eight ultraluminous X-ray sources in NGC 1559
Astronomers from Taiwan have performed X-ray observations of the galaxy NGC 1559 using NASA's Chandra spacecraft. They detected eight new ultraluminous X-ray sources in this galaxy. The finding is reported in a paper published August 10 on the pre-pr.....»»
Atlatl weapon use by prehistoric females equalized the division of labor while hunting, experimental study shows
A new study led by archaeologist Michelle Bebber, Ph.D., an assistant professor in Kent State University's Department of Anthropology, has demonstrated that the atlatl (i.e., spear thrower) functions as an "equalizer," a finding which supports women'.....»»
New type of star gives clues to mysterious origin of magnetars
