An international team of astronomers has employed NASA's Transiting Exoplanet Survey Satellite (TESS) to observe the eruption of Nova Vulpeculae 2021. Results of the observational campaign, published November 8 on the pre-print server arXiv, provide.....»»
Mighty radio bursts linked to massive galaxies: New clues about how magnetars form
Since their discovery in 2007, fast radio bursts—extremely energetic pulses of radio-frequency light—have lit up the sky repeatedly, leading astronomers on a chase to uncover their origins. Currently, confirmed fast radio bursts, or FRBs, number.....»»
Astronomers use JWST and ALMA to explore the structure of a giant spiral galaxy
Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers have observed a giant spiral galaxy designated ADF22.A1. Results of the observational campaign, published Oc.....»»
Volcanic ash as a source of nutrients: How the Hunga Tonga eruption affected ecosystems in the South Pacific
The eruption of Hunga Tonga-Hunga Ha'apai (HTHH) in January 2022 ejected about 2.9 billion tons of volcanic material into the atmosphere and across the South Pacific. In early 2022, a scientific expedition (GEOTRACES GP21) investigated the impact of.....»»
The RedMagic Nova is one of the best Android tablets I used in 2024
The RedMagic Nova is unapologetically a gamers tablet. But there's more to it than an overclocked silicon and a 20,000 RPM fan, all of which costs just $499......»»
Globular cluster Gran 5 hosts two stellar populations, study finds
Using the Gemini-South telescope, astronomers have performed high-resolution near-infrared spectroscopy of stars in a Galactic globular cluster known as Gran 5. They found that this cluster harbors two stellar populations with different metallicities.....»»
Webb confirms a longstanding galaxy model
Perhaps the greatest tool astronomers have is the ability to look backward in time. Since starlight takes time to reach us, astronomers can observe the history of the cosmos by capturing the light of distant galaxies......»»
New trigger proposed for record-smashing 2022 Tonga eruption—unstudied data from seismic wave points to early signals
Fifteen minutes before the massive January 2022 eruption of the Hunga Tonga-Hunga Ha'apai volcano, a seismic wave was recorded by two distant seismic stations. Now, researchers argue that similar early signals could be used to warn of other impending.....»»
Observations detect hundreds of possible supergiant stars in two nearby galaxies
Using the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Chinese astronomers have identified nearly 300 candidate supergiant stars in the Andromeda and Triangulum galaxies. The finding was reported in a research paper published O.....»»
Volcanic eruption burns houses in Indonesia, killing at least 10 people
Indonesia's National Disaster Management Agency said Monday that at least 10 people have died as a series of volcanic eruptions widens on the remote island of Flores......»»
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.....»»
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.....»»
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.....»»
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.....»»
Astronomers take a close look at a dandelion-shaped supernova and zombie star
In 1181, a new star shone near the Cassiopeia constellation for six months before disappearing. This event, recorded as a "guest star" by Chinese and Japanese observers almost a millennium ago, has puzzled astronomers for centuries. It is one of a fe.....»»
Astronomers discover a bright pulse that may be a fast radio burst
Searching for pulsars using the Large Phased Array (LPA) radio telescope, Russian astronomers have detected a bright pulse at a frequency of 111 MHz, which appears to be a fast radio burst event. The finding was reported in a research paper published.....»»
May 2024 super geomagnetic storm challenges current space weather prediction models
During May 2024, a series of eruption events on the sun saw the largest geomagnetic storm hit Earth in two decades. The largest since the solar storms of Halloween 2003, it occurred from May 10 to May 13, producing aurorae as far south as the Canary.....»»
