Washington, D.C. – NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.
SOFIA has detected water molecules (H2O) in Clavius Crater, one of the largest craters visible from Earth, located in the Moon’s southern hemisphere. Previous observations of the Moon’s surface detected some form of hydrogen, but were unable to distinguish between water and its close chemical relative, hydroxyl (OH).
Washington, D.C. – NASA’s telescope on an airplane, the Stratospheric Observatory for Infrared Astronomy, has provided a new glimpse of the chemistry in the inner region surrounding massive young stars where future planets could begin to form.
It found massive quantities of water and organic molecules in these swirling, disk-shaped clouds, offering new insights into how some of the key ingredients of life get incorporated into planets during the earliest stages of formation.
Washington, D.C. – The area around the supermassive black hole at the center of our Milky Way galaxy is dominated by gravity, but it’s not the only force at play. According to new research from NASA’s airborne telescope, the Stratospheric Observatory for Infrared Astronomy, or SOFIA, magnetic fields may be strong enough to control material moving around the black hole.
The research, presented this week at a meeting of the American Astronomical Society, could help answer longstanding mysteries about why our black hole is relatively quiet compared to others, and why the formation of new stars in our galaxy’s core is lower than expected.
Washington, D.C. – When the New Horizons spacecraft passed by Pluto in 2015, one of the many fascinating features its images revealed was that this small, frigid world in the distant solar system has a hazy atmosphere. Now, new data help
Remote observations of Pluto by NASA’s telescope on an airplane, the Stratospheric Observatory for Infrared Astronomy, or SOFIA, show that the thin haze enshrouding Pluto is made of very small particles that remain in the atmosphere for prolonged periods of time rather than immediately falling to the surface.
Washington, D.C. – The Stratospheric Observatory for Infrared Astronomy, SOFIA, studies the universe with infrared light. That’s a range of wavelengths on the infrared spectrum, from those measuring about 700 nanometers, too small to see with the naked eye, to about 1 millimeter, which is about the size of the head of a pin.
Other observatories, such as the Spitzer Space Telescope and Herschel Space Observatory, also studied infrared light. But each telescope observes different wavelengths of infrared light, filling in puzzle pieces that are essential to learning what makes the universe tick.
Washington, D.C. – NASA says one of the brightest and most massive star-forming regions in our galaxy, the Omega or Swan Nebula, came to resemble the shape resembling a swan’s neck we see today only relatively recently.
New observations reveal that its regions formed separately over multiple eras of star birth. The new image from the Stratospheric Observatory for Infrared Astronomy, or SOFIA, is helping scientists chronicle the history and evolution of this well-studied nebula.
“The present-day nebula holds the secrets that reveal its past; we just need to be able to uncover them,” said Wanggi Lim, a Universities Space Research Association scientist at the SOFIA Science Center at NASA’s Ames Research Center in California’s Silicon Valley.
Washington, D.C. – NASA has captured an extremely crisp infrared image of the center of our Milky Way galaxy. Spanning a distance of more than 600 light-years, this panorama reveals details within the dense swirls of gas and dust in high resolution, opening the door to future research into how massive stars are forming and what’s feeding the supermassive black hole at our galaxy’s core.
Among the features coming into focus are the jutting curves of the Arches Cluster containing the densest concentration of stars in our galaxy, as well as the Quintuplet Cluster with stars a million times brighter than our Sun. Our galaxy’s black hole takes shape with a glimpse of the fiery-looking ring of gas surrounding it.
Pasadena, CA – NASA says our Milky Way galaxy has an elegant spiral shape with long arms filled with stars, but exactly how it took this form has long puzzled scientists. New observations of another galaxy are shedding light on how spiral-shaped galaxies like our own get their iconic shape.
Magnetic fields play a strong role in shaping these galaxies, according to research from the Stratospheric Observatory for Infrared Astronomy, or SOFIA. Scientists measured magnetic fields along the spiral arms of the galaxy called NGC 1068, or M77. The fields are shown as streamlines that closely follow the circling arms.
Washington, D.C. – NASA says Mars may be a rocky planet, but it is not a hospitable world like Earth. It’s cold and dry with a thin atmosphere that has significantly less oxygen than Earth’s. But Mars likely once had liquid water, a key ingredient for life. Studying the history of water can help uncover how the Red Planet lost water and how much water it once had.
“We already knew that Mars was once a wet place,” said Curtis DeWitt, scientist at the Universities Space Research Association’s SOFIA Science Center. “But only by studying how present-day water is lost can we understand just how much existed in the deep past.”
Washington, D.C. – Even celestial objects can seem like they’re playing tricks. In a new study, scientists are puzzled by a black hole that seems to be changing its galactic surroundings in a way that is usually associated with newborn stars.
Black holes are inherently strange, with gravitational forces so strong that nothing, not even light, can escape. As active black holes consume gas and dust, some of that material is instead launched outward as jets of high-energy particles and radiation. Usually these jets are perpendicular to the host galaxy, but NASA’s Stratospheric Observatory for Infrared Astronomy, or SOFIA, found one that is shooting directly into its galaxy.
