The Color of Habitable Worlds
|
|
“This is where we live. On a Blue Dot.” said Carl Sagan when the now famous Pale Blue Dot photo was released. Captured February 14, 1990 by the Voyager 1 Space Probe, Pale Blue Dot remains the most distant photograph of the Earth ever taken at 6 billion kilometers. This past February marked the 30th …

Mixing Science and Art, One Painting at a Time
|
|
All her life, Laci Shea Brock has needed to be creative and inventive. So, perhaps it’s not completely surprising that in addition to pursuing her PhD in planetary sciences and astrophysics, she’s also a talented artist. “My Dad says I’ve always had a paintbrush in my hand,” Brock said, “and I’ve always been inspired by …

About 3% of Starlinks Have Failed So Far
|
|
A new analysis indicates that 3% of Starlink satellites have failed since they were launched to orbit, which could mean an increased risk of collisions down the road.

Geologists Have Found the Earth’s Missing Tectonic Plate
|
|
Northern Canada has been keeping a secret from the rest of the world. It’s home to “Resurrection,” a tectonic plate that has been much theorized but never found until now. A team of researchers used what amounts to a CAT scan of northern Canada and the mantle underneath it to find the missing plate. Finding …

Astronomers Find the Hollowed-Out Shell of a Dwarf Galaxy that Collided With the Milky Way Billions of Years Ago
|
|
In 2005 astronomers found a dense grouping of stars in the Virgo constellation. It looked like a star cluster, except further surveys showed that some of the stars are moving towards us, and some are moving away. That finding was unexpected and suggested the Stream was no simple star cluster. A 2019 study showed that …

Astronomers Challenge Recent Findings About Venus. “No Statistically Significant Detection of Phosphine”
|
|
In September, a team of scientists reported finding phosphine in the upper atmosphere of Venus. Phosphine can be a biomarker and is here on Earth. But it’s also present on Jupiter, where it’s produced abiotically. The discovery led to conjecture about what kind of life might survive in Venus’ atmosphere, continually producing the easily-degraded phosphine. …

Scientists Think They Know What Caused the Deadliest Mass Extinction in the History of the Earth
|
|
Humanity can have a love/hate relationship with itself, but there’s no denying that we’re the pinnacle of evolution on Earth as things stand now. But it took an awfully long time for evolution to produce beings such as we. Several times, life had to drag itself back from near annihilation. The largest extinction setback was …
