Move over Jupiter; Saturn is the new moon king. A team led by Carnegie's Scott S. Sheppard has found 20 new moons orbiting Saturn. This brings the ringed planet's total number of moons to 82, surpassing Jupiter, which has 79. The discovery was announced Monday by the International Astronomical Union's Minor Planet Center.
About 466 Mya, a major impact event took place between the orbits of Mars and Jupiter. Space dust spread all across the solar system, and some of it was found near Saint-Petersburg, Russia, and in the south of Sweden.
There is an as-yet-unseen population of Jupiter-like planets orbiting nearby Sun-like stars, awaiting discovery by future missions like NASA's WFIRST space telescope, according to new models of gas giant planet formation by Carnegie's Alan Boss, described in an upcoming publication in The Astrophysical Journal. His models are supported by a new Science paper on the surprising discovery of a gas giant planet orbiting a low-mass star.
About 466 million years ago, long before the age of the dinosaurs, the Earth froze. The seas began to ice over at the Earth's poles, and new species evolved with the new temperatures. The cause of this ice age was a mystery, until now: a new study in Science Advances argues that the ice age was caused by global cooling, triggered by extra dust in the atmosphere from a giant asteroid collision in outer space.
The first-ever comet from beyond our Solar System has been successfully imaged by the Gemini Observatory in multiple colors. The image of the newly discovered object, denoted C/2019 Q4 (Borisov), was obtained on the night of Sept. 9-10 using the Gemini Multi-Object Spectrograph on the Gemini North Telescope on Hawaii's Maunakea.
Harvard University researchers described a new, lower size limit for planets to maintain surface liquid water for long periods of time, extending the so-called Habitable or 'Goldilocks'' Zone for small, low-gravity planets. This research expands the search area for life in the universe and sheds light on the important process of atmospheric evolution on small planets.
Water vapour has been detected in the atmosphere of a super-Earth with habitable temperatures by UCL researchers in a world first.
The research centers on the asteroid impact that wiped out non-avian dinosaurs, with the researchers getting the most detailed look yet of the aftermath that followed by examining the rocks and debris that filled the crater within the first 24 hours after impact.
A team of scientists has discovered a new possible pathway toward forming carbon structures in space using a specialized chemical exploration technique at Berkeley Lab's Advanced Light Source.
University of Arizona researchers are using the Catalina Sky Survey's near-Earth object telescopes to locate the optical counterparts to gravitational waves triggered by massive mergers.
