Learning more about supernovae through stardust
Most of the diverse elements in the universe come from supernovae. We are, quite literally, made of the dust of those long-dead stars and other astrophysical processes. But the details of how it all comes about are something astronomers strive to und.....»»
Hubble and Webb probe surprisingly smooth disk around Vega
In the 1997 movie "Contact," adapted from Carl Sagan's 1985 novel, the lead character scientist Ellie Arroway (played by actor Jodi Foster) takes a space-alien-built wormhole ride to the star Vega. She emerges inside a snowstorm of debris encircling.....»»
Astronomers predict the orbits of potentially hazardous comets from meteor showers
Comets have long been seen as omens and portents, and it's easy to understand why. They first appear as faint smudges of light in the sky, sometimes fading soon after and sometimes becoming brighter than the planets, with a long, glowing tail. They h.....»»
Astronomers investigate the properties of open cluster NGC 2506
Astronomers from the University of Wisconsin–Madison and Harvard–Smithsonian Center for Astrophysics (CfA) have inspected a Galactic open cluster known as NGC 2506 as part of the WIYN Open Cluster Study. Results of the study, published October 14.....»»
Machine-learning analysis tracks the evolution of 16th-century European astronomical thought
A team of computer scientists, astronomers and historians in Berlin has used machine-learning applications to learn more about the evolutionary history of European astronomical thought in the 15th and 16th centuries. In their study published in the j.....»»
Researchers probe mechanical properties of silicon carbide
New research from the Ateneo de Manila University could pave the way for more durable versions of silicon carbide (SiC), a semiconductive ceramic material found mostly in space that has applications in everything from computer chips to spaceships......»»
New extended and faint tidal tail discovered
By analyzing the data from the Dark Energy Camera Legacy Survey (DECaLS), astronomers have discovered a new tidal tail likely associated with the galaxy NGC 3785. The newly detected tidal tail is extremely extended and faint. The finding was reported.....»»
Innovative model offers new way for astronomers to analyze powerful space explosions
Astrophysical explosions are, to give a few examples, driven by the collapse of the iron core of a massive star (known as a core-collapse supernova), the consumption of spaghettified stellar remains by a massive black hole (known as a tidal disruptio.....»»
Scientists provide direct evidence of breakdown of spin statistics in ion-atom charge exchange collisions
Since the first X-ray image of a comet was reported using an X-ray telescope in 1996, the investigation of charge exchange in collisions between highly charged ions and atoms or molecules has emerged as a hot research topic......»»
Astronomers discover one of the fastest-spinning stars in the universe
A new study by DTU Space researchers has revealed a neutron star that rotates around its axis at an extremely high speed. It spins 716 times per second, making it one of the fastest-spinning objects ever observed......»»
Observations explore the properties of giant spiral galaxy UGC 2885
Astronomers have employed the Canada-France-Hawaii Telescope (CFHT) to perform comprehensive multiwavelength observations of a large and massive spiral galaxy known as UGC 2885. Results of the observational campaign, published October 21 on the pre-p.....»»
Seeing a black hole"s jet in a new light: A look at high-energy particles being blasted across space
Research led by the University of Michigan has pored over more than two decades' worth of data from NASA's Chandra X-Ray Observatory to show there's new knotty science to discover around black holes......»»
