A Southwest Research Institute-led team discovered never-before-detected, fine-grained structures in the Sun's outer atmosphere, or corona. The team imaged this critical region in detail using sophisticated software techniques and longer exposures from the COR-2 camera on board NASA's Solar and Terrestrial Relations Observatory-A (STEREO-A).
Twelve new moons orbiting Jupiter have been found -- 11 'normal' outer moons, and one that they're calling an 'oddball.' A team led by Carnegie's Scott S. Sheppard first spotted the moons in the spring of 2017 while they were looking for very distant solar system objects as part of the hunt for a possible massive planet far beyond Pluto.
Scientists have found that molecular oxygen around comet 67P is not produced on its surface, as some suggested, but may be from its body.
Uranus was hit by a massive object roughly twice the size of Earth that caused the planet to tilt and could explain its freezing temperatures, according to new research.
A study appearing online Monday, July 2 in Nature Astronomy found at least 85 percent of 200,000 asteroids in the inner asteroid belt -- the main source of Earth's meteorites -- originate from five or six ancient minor planets.
Based on a new study of how near-Earth asteroid Phaethon reflects light at different angles, astronomers think that its surface may reflect less light than previously thought. This is an exciting mystery for the recently approved DESTINY+ mission to investigate when it flies past Phaethon.
New evidence for a rapid crystallization and crust formation on Mars has just been published in a study from the Centre for Star and Planet Formation at the Natural History Museum of Denmark, University of Copenhagen. The study, based on the analysis of the rare Mars meteorite Black Beauty, significantly expands the window for when life might have existed on Mars.
The interstellar object Oumuamua was discovered back on Oct. 19, 2017, but the puzzle of its true nature has taken months to unravel, and may never be fully solved. Meaning 'scout from the distant past' in Hawaiian, Oumuamua was found by astronomers working with the University of Hawaii's Pan-STARRS1 survey as it came close to Earth's orbit. But what is it: an asteroid or a comet?
Using observations from NASA's Hubble Space Telescope and ground-based observatories, an international team of scientists have confirmed ?Oumuamua (oh-MOO-ah-MOO-ah), the first known interstellar object to travel through our solar system, got an unexpected boost in speed and shift in trajectory as it passed through the inner solar system last year.
'Oumuamua, the first interstellar object discovered in the solar system, is moving away from the sun faster than expected. This anomalous behavior was detected using the NASA/ESA Hubble Space Telescope in cooperation with ground-based telescopes. The new results suggest that 'Oumuamua is most likely a comet and not an asteroid. The discovery appears in the journal Nature.
