'Weird Object' Discovered Beyond Neptune: A Clue in the Quest for Planet Nine?

The newly discovered object called Niku is a real oddity (artist’s conception). It is also part of a group of many such objects far past Neptune in the outer Solar System. Image Credit: ESO/L. Calçada/Nick Risinger

For the most part, the Solar System seems to be a rather well-ordered place; the planets, dwarf planets, […]

The New Horizons mission to Pluto has been nothing less than incredible, giving us our first close-up views of this enigmatic dwarf planet and its moons. But the show isn’t over yet, as the New Horizons […]

New 'KEM' Proposal Would Extend New Horizons Post-Pluto Mission to 2021

If approved by NASA, the KEM proposal will allow New Horizons to continue its study of the outer fringes of the Solar System until 2021, including a flyby of 2014 MU69. Image Credit: NASA/JHUAPL/SwRI

The New Horizons mission has revolutionized our understanding of Pluto and its moons, after conducting the first-ever flyby last summer. […]

The Changing Bright Spots of Ceres: New Evidence for Geological Activity?

Artist’s illustration of the brights spots Occator crater and elsewhere, based on a detailed map of the surface compiled from images taken from NASA’s Dawn spacecraft in orbit around the dwarf planet Ceres. New observations show that the bright spots change in brightness from day to night, suggesting that they change under the influence […]

This coming September, a new NASA spacecraft, OSIRIS-REx, will be heading toward an asteroid to collect samples which will later be brought back to Earth. This is the first time for such a sample return mission […]

Is 'Planet 9' Really a Second Massive Kuiper Belt?

The Kuiper Belt is a massive collection of dwarf planet- and asteroid-sized worlds orbiting far past Neptune. Is the hypothetical Planet 9 really a second such belt? Image Credit: T. Pyle (SSC)/JPL-Caltech/NASA

The announcement of a possible large ninth planet in our Solar System way beyond Neptune last month caused a lot of excitement, […]

Mystery Deepens: New Study Shows Comets Don't Explain Odd Dimming of Kepler's 'Weird Star'

The mystery surrounding KIC 8462852 may not involve comets after all, but it is still an enigma for astronomers. Image Credit: NASA/JPL-Caltech

As has been reported previously on AmericaSpace, and elsewhere, there is something weird going on around a star which is a little over 1,400 light-years away. Astronomers are still baffled as to […]
