    ALMA resumes surveillance after cyberattack

    (ORDO NEWS) — Forty-eight days after the suspension of observations due to a cyberattack, the Atakama Large Millimeter Wave [Antenna] Array (ALMA) is again observing the sky. The staff worked diligently to restore the damaged servers and services of the computer system. This is a critical milestone in the recovery process. On October 29, ALMA was cyberattacked. Countermeasures were immediately taken to avoid loss and damage to scientific data and…

    VLA and ALMA study Jupiter and Io

    (ORDO NEWS) — Several recent works illustrate how the VLA and ALMA telescopes are helping scientists study Jupiter and its moon Io. Jupiter’s atmosphere is complex and dynamic and changes rapidly. To explore the giant planet’s atmosphere at different depths, scientists combined observations made by instruments aboard NASA‘s Juno spacecraft with observations made by the VLA. They collected data on the distribution of residual ammonia gas at different levels of…

    Young open cluster NGC 602 explored with ALMA

    (ORDO NEWS) — Using the Atakama Large Millimeter Wave Array (ALMA), astronomers have studied the young open cluster NGC 602 in the Small Magellanic Cloud (LMC). The results of the study were published on August 29 at arXiv.org. Open clusters (OCs) are a group of weakly gravitationally bound stars formed from a single giant molecular cloud. To date, over 1,000 PCs have been found in the Milky Way, and the…

    ALMA studies newborn stars in the small Magellanic cloud

    (ORDO NEWS) — Researchers at Osaka University (OMU) observed newborn stars in the Small Magellanic Cloud, an environment similar to the early universe. Near one of the new stars, they found a molecular outflow with properties similar to those observed in the Milky Way galaxy. Heavy elements in interstellar matter significantly affect the mechanism of star formation. In the early universe, the abundance of heavy elements was lower than in…

    ALMA clarifies the size of a giant comet from the Oort cloud

    (ORDO NEWS) — The ALMA ground-based radio telescope helped astronomers refine the albedo and diameter of the nucleus of the giant comet C/2014 UN271 Bernardinelli-Bernstein from the Oort cloud. It turned out that it really is a record-breaking large one – the diameter was estimated at 137 kilometers. The core itself reflects only 5 percent of the light falling on it, which may be due to the presence of organics…
