Volcanic Activity Created Martian Geological Oddity

June 19, 2018

Scientists have long been puzzled by a mysterious formation located near the equator of Mars called Medusae Fossae. A new study from a pair of scientists – Lujendra Ojha and Kevin Lewis – at the Johns Hopkins University in Baltimore suggests that the large deposit of soft rock was probably formed as a result of violent volcanic eruptions that […]

Did our Sun Snatch Planet 9 from Another Solar System?

June 3, 2016

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. […]

Scientists Find Traces of Early Earth in Volcanic Rock

May 13, 2016

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 […]

Moon Born from a Violent Head-On Collision

February 1, 2016

It’s been theorized by a number of scientists that the moon was formed as the result of a collision between an early Earth and a protoplanet known as Theia, named after the mother of the goddess of the moon in Greek mythology, some 4.5 billion years ago (around 100 million years after Earth formed). But scientists seem […]

What Happens to Precipitation After it Falls to Earth? Have you ever wondered what happens to rain or snow once it falls on Earth? Researchers from the University of Utah and Oregon State University analyzed measurements, taken by the Tropospheric Emission Spectrometer (TES) on NASA’s Aura satellite, of the two forms of hydrogen contained within […]
