Astronomers are observing star-forming regions in our galaxy with NASA’s flying telescope, the Stratospheric Observatory for Infrared Astronomy, SOFIA, to understand the processes and environments required to create the largest known stars, which tip the scales at ten times the mass of our own Sun or more.
Astronomers from NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, Northwestern University, and the University of Maryland were on hand at the 231st meeting of the American Astronomical Society in Washington, D.C., to discuss new scientific results describing how their studies of dust grain polarization and celestial magnetic fields are leading to a better understanding of star formation, theories about how gas cools in the interstellar medium, and how magnetic fields are creating stellar winds around black holes.
NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, is preparing for its 2018 observing campaign, which will include observations of celestial magnetic fields, star-forming regions, comets, Saturn’s giant moon Titan and more.
This will be the fourth year of full operations for SOFIA, with observations planned between February 2018 and January 2019. Research flights will be conducted primarily from SOFIA’s home base at NASA’s Armstrong Flight Research Center. Highlights from these observations include:
Scientists were already excited to learn this summer that New Horizons’ next flyby target – a Kuiper Belt object a billion miles past Pluto -- might be either peanut-shaped or even two objects orbiting one another. Now new data hints that 2014 MU69 might have orbital company: a small moon.
Comets are our most direct link to the earliest stages of the formation and evolution of the solar system. Only every few years is a new comet discovered that is making its first trip to the inner solar system from the Oort Cloud, a zone of icy objects enveloping the solar system. Such opportunities offer astronomers a chance to study a special class of comets.
Researchers on the flying observatory SOFIA, the Stratospheric Observatory for Infrared Astronomy, are preparing for a two-minute opportunity to study the atmosphere of Neptune’s moon Triton as it casts a faint shadow on Earth’s surface. This is the first chance to investigate Triton’s atmosphere in 16 years.
The Stratospheric Observatory for Infrared Astronomy, SOFIA, completed its fourth set of observations from Christchurch, New Zealand. The team spent seven weeks operating from the U.S. Antarctic Program facility at Christchurch International Airport, enabling researchers onboard to observe celestial objects that are best studied from the Southern Hemisphere.
The Stratospheric Observatory for Infrared Astronomy, SOFIA, arrived in Christchurch, New Zealand, on June 22 to conduct seven weeks of observing flights from the Southern Hemisphere.
Researchers at the University of Texas San Antonio using observations from NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, found that the dust surrounding active, ravenous black holes are much more compact than previously thought.
An international team of researchers used NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, to make maps of the ring of molecular clouds that encircles the nucleus of galaxy IC 342. The maps determined the proportion of hot gas surrounding young stars as well as cooler gas available for future star formation. The SOFIA maps indicate that most of the gas in the central zone of IC 342, like the gas in a similar region of our Milky Way Galaxy, is heated by already-formed stars, and relatively little is in dormant clouds of raw material.
NASA’s flying observatory, the Stratospheric Observatory for Infrared Astronomy, SOFIA, recently completed a detailed study of a nearby planetary system. The investigations confirmed that this nearby planetary system has an architecture remarkably similar to that of our solar system.
On April 12, during a test of SOFIA’s systems involving an engine run, an anomaly occurred calling into question the flight-worthiness of Engines 1 and 4. The SOFIA maintenance team is investigating this issue. In the interim, program management has made a decision to replace the engines with spare engines. The observatory will resume flights after safety and engineering checks are completed. This down time has resulted in the estimated loss of at least eight science flights.
New observations show that Ceres, the largest body in the asteroid belt, does not appear to have the carbon-rich surface composition that space- and ground-based telescopes previously indicated.
For the first time since the twin Voyager spacecraft missions in 1979, scientists have produced far-infrared maps of Jupiter using NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA. These maps were created from the researchers’ studies of the circulation of gases within the gas giant planet’s atmosphere.
This is the first polarization image from the Stratospheric Observatory for Infrared Astronomy’s new infrared camera and polarimeter, known as the High-resolution Airborne Wideband Camera-plus (HAWC+). Polarimeters measure the alignment of incoming light waves, enabling HAWC+ to map magnetic fields in star forming regions.
Scientists on board NASA’s flying telescope, the Stratospheric Observatory for Infrared Astronomy, or SOFIA, caught sight of roiling material streaming from a newly formed star, which could spark the birth of a new generation of stars in the surrounding gas clouds.
NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, will soon be studying Neptune’s giant moon, Triton, and following-up on Hubble’s recent sighting of water plumes on Jupiter’s moon Europa. According to recently completed plans for the 2017 observing campaign, about half of the research time for SOFIA will run the gamut from studies of planets to observations of comets and asteroids orbiting other stars and supermassive black holes in the centers of galaxies beyond our own.
An international scientific team led by Dr. Alessio Caratti o Garatti from the Dublin Institute for Advanced Studies (Ireland) for the first time observed and analyzed an outburst from a high-mass young stellar object that was caused by material accreting onto the star.
Researchers on board NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, observed the collapse of portions of six interstellar clouds on their way to becoming new stars that will be much larger than our sun.
When a gas cloud collapses on itself, the cloud’s own gravity causes it to contract and the contraction produces heat friction. Heat from the contraction eventually causes the core to ignite hydrogen fusion reactions creating a star.
