Astronomers Witness a Supermassive Black Hole Roaring to Life Five years ago, a postulation 300 cardinal light-years distant got a batch brighter successful telescopes, radiating ultraviolet, optical, and infrared airy retired into space. This year, the resurgent postulation started emitting X-rays, indicating that its archetypal brightening was truly conscionable a warmup. First Full-Color Images From Webb Space Telescope For the 2 decades earlier 2019, the postulation was the aforesaid level of faintness successful the nighttime sky. According to a squad of astronomers, the caller wind-up could beryllium owed to a supermassive achromatic spread coming to beingness astatine the galaxy’s core. The team’s probe is accepted for publication successful Astronomy & Astrophysics. “This behaviour is unprecedented,” said Paula Sánchez Sáez, a researcher with the Millennium Institute of Astrophysics successful Chile and pb writer of the paper, successful a European Southern Observatory release. “Regardless of the quality of the variations, [this galaxy] provides invaluable accusation connected however achromatic holes turn and evolve.” The postulation is SDSS1335+0728 (and that’s conscionable its nickname—seriously!). Its archetypal brightening was spotted by the Zwicky Transient Facility telescope, which puts retired an alert connected an entity erstwhile a five-sigma detection is made of a source’s quality image. The researchers concluded that the brightness variations bespeak a achromatic hole, astir 1 cardinal times the wide of the Sun, is becoming active, brightening its surroundings arsenic it consumes material. The entity lone began emitting X-rays successful February, indicating that the achromatic spread is adjacent much awake present than erstwhile it began to stir. “These elephantine monsters usually are sleeping and not straight visible,” said survey co-author Claudio Ricci, from the Diego Portales University, successful the aforesaid release. “In the lawsuit of SDSS1335+0728, we were capable to observe the awakening of the monolithic achromatic hole, [which] abruptly started to feast connected state disposable successful its surroundings, becoming precise bright.” The squad has yet to behaviour follow-up observations to clarify the quality of the event. While the information powerfully suggests the squad saw the achromatic hole’s activation, it’s imaginable that the lawsuit is simply a rare benignant of tidal disruption, successful which a adjacent passing entity is pulled isolated by the achromatic hole’s gravitational force, lighting up the surrounding cosmos. If it is simply a tidal disruption, it’s the longest and faintest yet seen. Instruments similar the Very Large Telescope and its successor, the Extremely Large Telescope, could spot much airy from these rare, adaptable events. At the ...

Hi all, I'm excited to share the completion of my computation-based astronomy project, conducted by KRITTIKA club of astronomy at #IITBombay. Over the course of this project, I utilized data from the #Gaia satellite 🛰 to determine the age, metallicity, and distances of various star clusters✨. I want to thank Aditya Saran and Aryan Kumar for their guidance and mentorship throughout the project 🙂. #Astronomy🚀 #Research #StellarClusters #DataAnalysis

📰 Recent Article Spotlight: In astronomy, a stellar occultation occurs when a small body within the Solar System passes in front of a background star. Such events provide a way of measuring the shapes and sizes of these small objects. In a recent article, Ben Attwood creates software to perform high-speed, automated photometry on spool files containing large volumes of images from the European Southern Observatory's 1.54 m Danish Telescope. The article describes the methodology behind the code and shows its use in successfully detecting three occultation events, which could be compared to previous literature.

Are there exoplanets similar to Earth, where life can exist? How do these exoplanets evolve over time? To get one step closer to answering these questions, a team of astronomers, including UvA researchers Saugata Barat and Jean-Michel Desert, investigated the atmosphere of a very young exoplanet. They published their results in Nature Astronomy. There is a lot of research on a category of exoplanets with sizes between Earth and Neptune. However, crucial knowledge about the origin and evolution of these planets is lacking. The astronomers therefore observed the atmosphere of the young exoplanet named V1298 Tau b using the Hubble Space Telescope. They also revealed the first-ever transmission spectrum of a young planet. The researchers found that the planet’s atmosphere spans around 1000 kilometres and mostly consists of hydrogen and helium, with traces of water vapor. This is very different from the types of atmospheres of solar bodies like Titan. Titan’s atmosphere only spans approximately 50 kilometres and contains mostly heavier elements such as carbon and oxygen. By directly comparing the atmospheric spectrum of the young exoplanet with its mature counterparts, the researchers found many differences in their nature, chemistry, and composition. One of these differences is that the young exoplanet has fewer heavy elements compared to more mature exoplanets. Building upon this research, scientists want to delve deeper into the atmospheres of young exoplanets with the James Webb Space Telescope to further unravel the mysteries of planetary evolution.

Our founder Max Morales is a #eclipsechaser and Specialized High End #tourguide for small groups that managed a group of Caltech in 2019 to #SolarEclipse found this interesting article Cosmic Streams 2023: World experts in #astronomy discuss the use and impact of AI and the new mega #telescope in Chile In 2024 Chile and the world will witness an astronomical milestone that will revolutionize the study of the universe. From the summit of Cerro Pachón, in the Coquimbo region, the Vera Rubin Observatory will begin the test phase, or “commissioning”, of the systems that will allow -next year- the beginning of a decade of unprecedented scientific research called “Legacy Survey of Space and Time”. This project, unique at the planetary level for its 3,200 megapixel digital telescopic camera, will produce an unprecedented astronomical catalog database, providing 20 terabytes of data per night and 200 petabytes at the end of its operation, which already challenges the scientific community to process data in real time. As a result of this and other scientific milestones, the Millennium Institute of Astrophysics (MAS), which is celebrating 10 years of operation, together with the Center for Mathematical Modeling (CMM) of the University of Chile, organized the international congress “Unveiling the dynamic universe: cosmic streams in the era of Rubin”, or simply Cosmic Streams, which will be held in Puerto Varas, in the Los Lagos region, from December 11 to 15, 2023. “The main objective of this congress is to connect the search telescopes with the tracking telescopes, together with the brokers and the software infrastructure in general that help these systems to interact. Cosmic Streams will be where astronomy will begin to be designed for the next decades”, explains Francisco Förster, MAS-CMM researcher and director of ALeRCE, the Chilean broker that was chosen -along with six others worldwide- to analyze the Vera Rubin data. ALeRCE, a project of MAS, CMM, Data Observatory and the Universidad de Concepción, has processed to date about 300 million alerts of objects and events in the universe, coming from other instruments such as: the Zwicky Transient Facility (ZTF), a large field-of-view telescope located in California, USA, which scans the entire sky every other night and is also modifying its way of operating, doubling and complexifying the amount of data released; and from ATLAS, a set of four telescopes located in the northern and southern hemisphere to track asteroids, one of which is located in the commune of Rio Hurtado in Chile, thanks to an alliance between MAS and the University of Hawaii.
