Was Mars Always Destined to Be Dry? New Study Offers a Fresh Theory

Astronomy, Planetary Science /

One of the biggest mysteries in planetary science is etched into Mars’ landscape. The planet’s vast river-carved canyons reveal it was once warm enough to support flowing liquid water. So how did it transform into the dry, lifeless desert we see today—and why? A new study led by University of Chicago planetary scientist Edwin Kite

Japanese Scientists Reveal the Exact Date of Earth’s End — and It’s Already Set

Astronomy, Planetary Science /

Researchers from Tohoku University, in collaboration with NASA, conducted a study predicting the end of life on Earth in the year 1,000,002,021. Using supercomputers, they simulated the Sun’s behavior over billions of years and concluded that the gradual increase in solar radiation will make the planet uninhabitable. As the Sun ages, it will expand, emitting

Scientists Confirm Ongoing ‘Sputtering’ of Mars’ Atmosphere

Astronomy, Planetary Science /

For the first time, scientists have directly observed a key process driving the continuous loss of Mars’ atmosphere. Decade-Long Research Leads to Discovery After more than nine years of satellite data analysis, a team led by planetary scientist Shannon Curry from the University of Colorado Boulder has identified clear evidence of atmospheric sputtering. According to

Study Suggests Hidden Danger May Be Orbiting Alongside Venus

Astronomy, Planetary Science /

Two decades ago, the U.S. Congress tasked NASA with identifying 90% of near-Earth asteroids that could pose a threat. Since then, the agency has made progress tracking objects that orbit the Sun and pass within 1.3 astronomical units of Earth. A New Threat Emerging Near Venus However, a new area of concern is emerging: astronomers

How Light Travels Across the Universe Without Losing Energy

Planetary Science, Space & Environment /

One evening in my light-polluted San Diego backyard, I had my telescope set up for astrophotography and aimed it at an incredibly distant galaxy. As the first image appeared on my tablet screen, my wife, Cristina, came over. “That’s the Pinwheel Galaxy,” I told her—named for its spiral shape and home to roughly a trillion

A Magnetar’s Unexpected Origins Add New Depth to a Cosmic Mystery

Astronomy, Planetary Science /

On the edge of our galaxy, one of the universe’s rarest stellar objects just became even more puzzling.Using data from the Hubble Space Telescope and the Gaia observatory, astronomers examined the environment around SGR 0501+4516, a magnetar — a highly magnetized type of neutron star. Their findings suggest that our current understanding of how magnetars

North America Is Sinking Into the Earth’s Mantle

Planetary Science /

A study published in the journal Nature Geoscience has revealed a subtle yet significant phenomenon beneath the North American continent: its ancient bedrock is slowly sinking into the Earth’s mantle. This descent occurs in a drip-like fashion, forming a funnel-shaped structure concentrated in the Midwestern United States, which pulls the ancient rocks horizontally before they
