Astronomers have discovered a frozen, water-rich planetary fragment being consumed by a white dwarf star outside our Solar System. The object is thought to be an icy planetesimal, possibly similar to Halley's Comet or Pluto, and has a high nitrogen abundance, making it a rare finding in the field.
A team of researchers has found a stable trio of icy space rocks in the Kuiper Belt using data from NASA's Hubble Space Telescope and the W. M. Keck Observatory. The Altjira system suggests that similar triples may exist, supporting a theory of solar system formation and the formation of Kuiper Belt objects.
A Southwest Research Institute-led team developed a revised solar composition that potentially reconciles spectroscopy and helioseismology measurements for the first time. The new solar composition suggests higher levels of carbon, nitrogen, and oxygen in the Sun than previously thought.
The Subaru Telescope has discovered new bodies beyond the Kuiper Belt edge, likely part of a larger population waiting to be found. This discovery challenges our understanding of the Solar System's structure and history, and may increase the chances of finding alien life.
A new study on comets suggests that Kuiper Belt Objects like Arrokoth may contain ancient ices from billions of years ago. Researchers found a domino effect where the object's interior gets colder, preserving volatile gases for billions of years.
A recent study challenges previous notions about the evolutionary path of Kuiper Belt Objects (KBOs), suggesting they can retain their original volatile ices for billions of years. This discovery could help explain phenomena like comet outburst activity, potentially changing our understanding of comets.
Researchers found evidence of hydrothermal or metamorphic activity within the icy dwarf planets Eris and Makemake, which have methane deposits with geochemical origins. The discovery suggests elevated temperatures in their rocky cores, potentially leading to liquid water and habitability.
A new SwRI study posits that the large mounds on Kuiper Belt object Arrokoth are similar in size and shape, suggesting a common origin. This finding supports the streaming instability model of planetesimal formation, where gentle collision speeds allowed objects to accumulate and form Arrokoth.
A new study suggests that the Hypatia Stone, discovered in Egypt, may be the first tangible evidence on Earth of a supernova type Ia explosion. The stone's unique chemistry and elemental composition contradict conventional views of solar system formation, potentially revealing a long-hidden secret about our cosmic neighborhood.
A new study by Rice University astrophysicist André Izidoro suggests that the sun had rings before planets formed, explaining many solar system features. The model simulates the solar system's formation hundreds of times and reproduces several features missed by previous models, including pressure bumps and rings.
A Southwest Research Institute-led team of scientists have discovered a lack of very small Kuiper Belt objects with crater counts on Pluto's satellite Charon indicating fewer impactors smaller than 1 mile in diameter than predicted. This finding has deep implications for our understanding of the solar system's origin and evolution.
Researchers mapped scars on Pluto and Charon to determine size distribution of small Kuiper belt objects, revealing a lack of craters smaller than 13 km in diameter. This finding suggests that constituent objects may have survived intact since the Solar System's earliest days.
An international team of astronomers has discovered a carbon-rich asteroid in the Kuiper Belt, providing strong support for theoretical models of the Solar System's formation. The asteroid, 2004 EW95, is believed to have formed in the inner Solar System and was flung outwards by a migratory planet.
Astronomers have confirmed the presence of two new moons around Pluto, provisionally designated S/2005 P 1 and S/2005 P 2. The new discoveries were made possible by the exceptional resolution of the Hubble Space Telescope, which revealed the small moons' orbits with similarities to Charon's.
