The Earth may be traveling through the debris of an ancient supernova explosion
The Earth is flying through a cloud of radioactive debris left behind by an ancient supernova explosion, according to a new report by scientists looking at our oceans. A team from the Australian National University (ANU) has made this conclusion after studying radioactive dust found at the bottom of our oceans. While this dust is in small enough […]

Cradles of life? New research says oceans on exoplanets may harbor more life than Earth
A study published in the Astrophysical Journal suggests that oceans on exoplanets may be more hospitable than those on Earth. Scientists traditionally detect which exoplanet is potentially habitable by looking for conditions that closely mimic those on Earth. However, exoplanets that greatly vary from the Earth in terms of conditions such as ocean salinity may, in fact, be more primed […]

Breakthrough in the search for extraterrestrial life as scientists discovered stars could host as many as 7 habitable planets
A recent study published in the Astronomical Journal found that as much as seven habitable planets could be orbiting a star, advancing the search for extraterrestrial life forms. The researchers noted that the absence of a gas giant such as Jupiter can mean more planets could have the favorable conditions to facilitate life. This factor could […]

Violent collisions in space millions of years ago led to 100 times more meteorite impacts on Earth and unleashed space dust, studies suggest
Meteorites taken from the Thorsberg quarry in Sweden suggest that violent collisions occurred in space about 470 million years ago, flinging rapidly traveling meteorites toward Earth. Birger Schmitz of Lund University in Sweden is leading the research on the meteorites aged millions of years old. His team’s findings, published in the journal Nature, show that the meteorites hold new and […]

“Snowball Earth” from eons ago may have been caused by a rapid decrease in incoming sunlight, says study
There are at least two instances in which the Earth was completely smothered by ice. This icy world, often called Snowball Earth, is believed to have occurred around 700 million years ago. It was characterized by the global expansion of ice that makes Earth look like a snowball from outer space. Its exact cause remains unknown, although experts posit […]

Global magnetic anomaly hit the Earth out of nowhere during deep solar minimum
On June 23, astronomers detected an unusual wave of magnetism hitting the Earth. What makes this event unusual is that this is occurring during the deepest solar minimum in a century, and these kinds of geomagnetic activity should not be happening. The Sun is usually filled with activity. Using special, filtered telescopes, astronomers can see that the Sun is filled […]

Nearby “super-Earth” exoplanet could support life, suggest scientists
Astronomers have found an exoplanet – a planet located outside of the Solar System – that they believe may be capable of supporting life. An international group of astronomers made the discovery with the help of NASA’s Transiting Exoplanet Survey Satellite (TESS). Dubbed a “super-Earth,” the exoplanet was found in the Hydra constellation, about 31 […]

Astronomers debunk the mystery of Earth’s “space cones”
Earth is filled with cones that come from space. Fortunately, astronomers have figured out that they aren’t as mysterious as people previously believed – as it turns out, they’re just meteorites that plunged into the Earth’s atmosphere. Since the Earth began forming around 4.5 billion years ago, it has been peppered by asteroids and meteors alike. The […]

The Earth’s mantle is a “geochemically diverse mosaic,” reveals team of geologists
The typical visual depiction of the Earth’s mantle as a solid band of yellow-orange sitting between the crust and core has just received an update. A recent paper in Nature Geoscience now describes it as “more heterogenous” than what people previously thought. An international group led by the University of Utah provided a more diverse representation of the mantle, far different compared […]

Mesmerized by the ocean? To understand why the moon is where it is, start with Earth’s tides
As far as the human race remembers, the moon has always been there. But how did it get up there in the first place – and what keeps it revolving around Earth? By firing lasers at artificial mirrors deployed on the moon, researchers have learned that Earth’s satellite is drifting away at the rate of […]
