Calibrating an instrument is like tuning a piano or a guitar before a concert. "Calibrating an instrument is like tuning a piano or a guitar before a concert," explains Maxime Rizzo, another of the engineers responsible for this element. #TelescopioRoman #NASA #Astronomía (translated)
NASA has made a tiny adjustment to the secondary mirror of the Nancy Grace Roman Space Telescope during its journey to the Sun-Earth L2 point, preparing the instrument for its mission to observe the universe with unprecedented capability and precision. #TelescopioRoman #NASA #Astronomía (translated)
A team of astronomers from the University of Warwick has discovered the first known green star in our galaxy, WD J1330+6435, challenging the belief that the color of stars depends solely on their temperature. #EstrellaVerde #Astronomía #DescubrimientoCientífico (translated)
Astronomers from the University of Warwick have discovered the first green star, a white dwarf, whose unusual color is the result of the presence of calcium, sodium, and lithium in its atmosphere. #astronomia #zielonagwiazda #białekarły (translated)
A new study reveals that white dwarfs, historically considered white or blue, can also shine in unexpected tones such as green, pink, or yellow due to the chemistry of their atmospheres. #Estrellas #Astronomía #EnanasBlancas (translated)
Astronomers from the University of Warwick have discovered a green star, the white dwarf WDJ1330+6435, a novel phenomenon that occurs due to the accumulation of sodium-rich rocky material in its atmosphere. (translated)
An international study led by the National Institute of Astrophysics has revealed that the character of planets is influenced by their mother star, with more massive stars creating turbulent planetary systems, while stars similar to or smaller than the Sun produce calmer and more compact systems. #Astronomia #SistemiPlanetari #RicercaSpaziale (translated)
In fact, Halzen has acknowledged that IceCube was in a way a gamble, as n #Astronomía #Neutrinos #IceCube (translated)
The Nobel Prize in Physics 2026 has been awarded to Francis Halzen for his innovative contributions to the IceCube observatory, which captures cosmic neutrinos from a cubic kilometer of ice in Antarctica, thus revolutionizing our understanding of the universe. #Astronomía #Neutrinos #IceCube (translated)
A sensational discovery in 2026 revealed IRAS 18293−0941, a black hole 12,000 light-years from Earth that is absorbing a star and shooting jets of matter directly toward our planet. #BucoNero #Astronomia #ScopertaScientifica (translated)
The Ariel mission, led by astronomer Giovanna Tinetti, will explore Earth's cousins in the galaxy. #astronomia #galassia #missioneAriel (translated)
A study suggests that jets from supermassive black holes can kill galaxies by inhibiting their ability to form stars, thus affecting their evolution. #Astronomía #AgujerosNegros #Galaxias (translated)
A study reveals that the stability of the Solar System could be seriously compromised in the 3 billion years following the transformation of the Sun into a white dwarf, due to expulsions of solar material that would affect the orbits of the giant planets. #SistemaSolar #Astronomía #InestabilidadOrbital (translated)
"Not receiving it would have made me feel like I was disappointing my extraordinary collaborators." Halzen, who has dedicated about 35 years to the development of neutrino experiments, also expresses relief for the Nobel: "Not receiving it would have made me feel like I was disappointing my extraordinary collaborators." #Neutrini #NobelFisica #Astronomia (translated)
Francis Halzen, recently awarded the Nobel Prize in Physics 2026, discusses in Turin about neutrino astronomy and the impact that a single cosmic event can have on decades of scientific research. #Neutrini #NobelFisica #Astronomia (translated)
A comet-like fireball, which reached a speed of 256,000 km/h, was observed crossing the sky of Almería during the early morning of October 5, according to the Calar Alto Astronomical Observatory. #BolaDeFuego #Almería #Astronomía (translated)
A team of astronomers has detected for the first time a radio signal coming from the exoplanet Beta Pictoris b, originating from auroras generated by its magnetic field, which is more than 200 times stronger than Jupiter's, although it is not indicative of intelligent life. #Exoplaneta #EmisionesDeRadio #Astronomía (translated)
An international team of astronomers has captured the most detailed image of Pa 30, the remnant of a historical supernova associated with an event observed in 1181, revealing chains of gas that resemble pearls and highlighting the presence of a zombie star in its core. #Pa30 #Supernova #Astronomía (translated)
"Second-generation planets are worlds that form from the material that a star expels when it dies. They are incredibly rare, and finding one around a white dwarf was completely unexpected," explains Jamie Williams, the first author of the study. #Planeta #Astronomía #EnanaBlanca (translated)
A team of astronomers has discovered the first known second-generation planet, similar to Jupiter, that formed from the material expelled by its star during its death, orbiting a white dwarf. #Planeta #Astronomía #EnanaBlanca (translated)
