Southwest Research Institute scientists integrated NASA's New Horizons discoveries with data from ESA's Rosetta mission to develop a new theory about how Pluto may have formed at the edge of our solar system.
The object is revolving around the sun in the vicinity of Jupiter but in the opposite direction from most other celestial bodies, according to a study featuring a Brazilian scientist as co-author. Through a computer simulation, the study shows that the orbit has been stable since the giant planets were formed.
A new study has discovered the first known permanent immigrant to our solar system. The asteroid, currently nestling in Jupiter's orbit, is the first known asteroid to have been captured from another star system. The work is published in Monthly Notices of the Royal Astronomical Society: Letters.
An international team of astronomers has used ESO telescopes to investigate a relic of the primordial solar system. The team found that the unusual Kuiper Belt Object 2004 EW95 is a carbon-rich asteroid, the first of its kind to be confirmed in the cold outer reaches of the Solar System. This curious object likely formed in the asteroid belt between Mars and Jupiter and has been flung billions of kilometers from its origin to its current home in the Kuiper Belt.
New research shows that a surprising amount of water survives simulated asteroid impacts, a finding that may help explain how asteroids deposit water throughout the solar system.
A telescope in outback Australia has been used to listen to a mysterious cigar-shaped object that entered our solar system late last year. When 'Oumuamua was first discovered, astronomers thought it was a comet or an asteroid from within the solar system. But after studying its orbit and discovering its long, cylindrical shape, they realized 'Oumuamua was neither and had come from interstellar space.
Work by Cardiff University astronomers suggests there may be a cosmic lack of a chemical element essential to life. Dr Jane Greaves and Dr. Phil Cigan will present their results at the European Week of Astronomy and Space Science in Liverpool.
The first interstellar object ever seen in our solar system, named 'Oumuamua, is giving scientists a fresh perspective on how planets, asteroids and comets form.
About 70,000 years ago, when the human species was already on Earth, a small reddish star approached our solar system and gravitationally disturbed comets and asteroids. Astronomers from the Complutense University of Madrid and the University of Cambridge have verified that the movement of some of these objects is still marked by that stellar encounter.
New research finds that 'Oumuamua, the rocky object identified as the first confirmed interstellar asteroid, very likely came from a binary star system.
