New exoplanet detected with the ESPRESSO spectrograph
Using the Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations (ESPRESSO), astronomers from Switzerland and Austria have discovered a new alien world. The newfound exoplanet orbits a nearby M dwarf star and is at least four.....»»
Big planets don"t necessarily mean big moons
Does the size of an exomoon help determine if life could form on an exoplanet it's orbiting? This is something a February 2022 study published in Nature Communications hoped to address as a team of researchers investigated the potential for large exo.....»»
Astronomers discover extremely hot exoplanet with ‘lava hemisphere’
An Earth-sized orbits a star similar to our sun, but much, much closer - meaning it has surface temperatures of nearly 2,300 degrees Fahrenheit......»»
Venus" atmospheric chemical anomalies may motivate future astrobiology missions
When scientists detected phosphine in Venus' atmosphere in 2020, it triggered renewed, animated discussions about Venus and its potential habitability. It would be weird if the detection didn't generate interest since phosphine is a potential biomark.....»»
Akira ransomware attackers are wiping NAS and tape backups
“The Akira ransomware malware, which was first detected in Finland in June 2023, has been particularly active at the end of the year,” the Finnish National Cybersecurity Center (NCSC-FI) has shared on Wednesday. NCSC-FI has received 12 re.....»»
Astronomers found ultra-hot, Earth-sized exoplanet with a lava hemisphere
Also: A separate team found a small, cold exoplanet with a massive outer companion. Enlarge / Like Kepler-10 b, illustrated above, newly discovered exoplanet HD 63433 d is a small, rocky planet in a tight orbit of its star. (cre.....»»
Nafion byproduct 2 found in blood of well users near Fayetteville, N.C.
Researchers from the GenX Exposure Study detected PFAS originating from a fluorochemical manufacturing plant—including Nafion byproduct 2 and GenX—in nearby private wells in Bladen and Cumberland Counties, N.C. PFAS refers to a group of chemicals.....»»
New large stellar flare detected from EV Lacertae
Astronomers have performed multiwavelength observations of a nearby M-dwarf star known as EV Lacertae (or EV Lac for short). The observational campaign resulted in the detection of a new large stellar flare from this object. The finding was detailed.....»»
"Blob-like" home of farthest-known fast radio burst is collection of seven galaxies, researchers find
In summer 2022, astronomers detected the most powerful fast radio burst (FRB) ever observed. And coming from a location that dates halfway back to the Big Bang, it also was the farthest known FRB spotted to date......»»
A Jupiter-sized planet has been hiding a big secret: A 350,000-mile-long tail
WASP-69b is having a hot girl summer that never ends. The huge gaseous exoplanet, roughly the size of Jupiter and approximately 160 light years from Earth, orbits its searing host star so closely that its atmosphere is boiling away at a rate of 200,0.....»»
Secrets of a hot Saturn and its spotted star unlocked
A team of astronomers including McGill Professor Nicolas Cowan has unraveled the enigmatic atmosphere of the exoplanet HAT-P-18 b, shedding light on its intriguing blend of gases, clouds, and even the effects of its star's activity.....»»
Gliese 367 b is a dark and hot sub-Earth with no atmosphere, study finds
Using the James Webb Space Telescope (JWST), astronomers have investigated a nearby sub-Earth exoplanet known as Gliese 367 b. The obtained results indicate that this alien world is dark, hot and lacks a detectable atmosphere. The new findings were p.....»»
Seeking another Earth? Look for low carbon dioxide
In our own Solar System, Earth has far lower CO2 concentrations than its neighbors. Enlarge (credit: NASA/JPL/Caltech) What do we need to find if we want to discover another Earth? If an exoplanet is too far away for eve.....»»
Scientists flip around gravitational-wave data analysis: Have LIGO and Virgo detected a merger of dark-matter stars?
Gravitational waves are ripples in the fabric of spacetime that travel at the speed of light. These are produced in some of the most violent events in the universe, such as black-hole mergers, supernovae, or the Big Bang itself. Since their first det.....»»
See the weather patterns on a wild, super hot exoplanet
Planet WASP-121 b has a surface temperature of 5,000 degrees Fahrenheit, which researchers predict would lead to some wild weather phenomena......»»
Pulsations detected from the XZ Ursae Majoris system
Astronomers have conducted a photometric and spectroscopic study of an Algol-type binary, known as XZ Ursae Majoris (or XZ UMa for short). Results of the study, presented in a paper published December 21 on the pre-print server arXiv, indicate that t.....»»
TRAPPIST-1c isn"t the exo-Venus we were hoping for, but don"t blame the star
A recent study posted to the arXiv preprint server and accepted to The Astrophysical Journal uses computer models to investigate why the exoplanet, TRAPPIST-1c, could not possess a thick carbon dioxide (CO2) atmosphere despite it receiving the same a.....»»
First pulsar detected in globular cluster GLIMPSE-C01
Using the Karl G. Jansky Very Large Array (VLA), astronomers have discovered a millisecond pulsar in the globular cluster GLIMPSE-C01 as part of the VLA Low-band Ionosphere and Transient Experiment (VLITE). This is the first pulsar ever detected in t.....»»
The atmosphere of an exoplanet reveals secrets about its surface
As astronomers have begun to gather data on the atmospheres of planets, we're learning about their compositions and evolution. Thick atmospheres are the easiest to study, but these same thick atmospheres can hide the surface of a planet from view. A.....»»
Researchers argue back and forth about whether we’ve spotted an exomoon
Years after Kepler shut down, people are arguing over whether it spotted exomoons. Enlarge (credit: NASA) In 2017, the astronomy world was abuzz at the announcement that exoplanet Kepler-1625b potentially had its own moo.....»»
