A new study from researchers at the California Institute of Technology (Caltech) suggests that Planet 9, the huge and so far unseen planet said to be lurking in the far reaches of the solar system, might be causing our group of planets to wobble a little and giving an impression that the sun is slightly tilted.

Astronomers Find a Cosmic Cannon Astronomers have spotted super-hot blobs of plasma blasting into space like cannonballs near a dying red giant star, some 1,200 light years away. Using the Hubble Space Telescope to make their discovery, the scientists found that the balls of hot gas are flying so fast a trip from the Earth […]

After NASA’s Dawn spacecraft had passed by the asteroid Vesta, on its way to rendezvous with Ceres, mission scientists noticed that its surface was banged up with a lot of very large craters.  Its biggest impact crater is Rheasilvia, which measures 505 km in diameter. They expected that Ceres would also be seriously pitted with giant impact basins too. […]

Among my fondest memories of being a kid back in the 1960’s was taking a week or so of summer vacation to visit relatives at my grandfather’s farm in Herman, PA (about 65 km northeast of Pittsburgh). During my stay I would spend evenings lying on the freshly cut grass of my grandpa’s back yard, just looking up into […]

Is it possible that the new-found theoretical Planet 9 is actually an exoplanet, a planet from another solar system? According to astronomers at Sweden’s Lund University, it’s “highly likely” that Planet 9 was actually “snatched” from another solar system by our young sun some 4.5 billion years ago, or within 100 million years after its formation. […]

According to most scientists, Earth was formed between 4.5 and 4.6 billion years ago after gravity forced gas and dust left over from the creation of the Sun accreted into an object called a planetesimal. Over time, the planetesimal continued to gather more and more material and eventually became a planet. Scientists say heat produced […]

Hubble Spots Moon Circling Distant Dwarf Planet Out in the far reaches of our solar system lies the Kuiper Belt.  This region of space is occupied by icy objects left over from the creation of the solar system. Several dwarf planets, such as Pluto, also occupy the Kuiper Belt. Astronomers studying images gathered by the […]

Artist Animation of Star Explosion (NASA/JPL/Australian National University) Two new studies suggest radioactive bits of a nearby star or stars that exploded into a supernova or supernovae showered the Earth and Moon with radioactive iron a couple of million years ago. Both studies found the stellar evidence in concentrations of an isotope of iron called […]
