Astronomers Stunned by the Unusual “Inside-Out” Structure of a Solar System

Astronomy, Planetary Science /

Astonished astronomers reported Thursday the discovery of a star whose planets are arranged in an unusual sequence that challenges established scientific understanding, indicating these distant worlds may have formed in a way never observed before. In our Solar System, the four planets nearest the Sun are small and rocky, while the four outer planets are […]

New Radio Method Detects Hidden Dwarf Star Bursts, Hints at Exoplanets

Astronomy, Planetary Science /

An international team, including Cornell’s Jake Turner, developed a method to uncover hidden stellar and exoplanetary signals in archival radio data. Using this technique, scientists have identified new radio bursts from dwarf stars and potentially from exoplanets. The method, Multiplexed Interferometric Radio Spectroscopy (RIMS), reveals some signals linked to star–planet interactions. The findings appeared in

BepiColombo Mio and GEOTAIL Observe Similar Magnetosphere Wave Frequencies

Astronomy, Planetary Science /

An international team from Kanazawa University (Japan), Tohoku University (Japan), LPP (France), and collaborators has shown that chorus emissions—natural electromagnetic waves well-known in Earth’s magnetosphere—also appear in Mercury’s magnetosphere, displaying similar chirping frequency patterns. BepiColombo’s Mio recorded audible plasma waves during six Mercury flybys from 2021 to 2025. Comparison with decades of GEOTAIL data showed

Rocky Exoplanets Might be Shielded from Radiation by Magma Oceans

Astronomy, Planetary Science /

Far below the surface of distant super-Earth exoplanets, vast oceans of molten rock could be generating powerful magnetic fields capable of protecting the planets from hazardous cosmic radiation and other high-energy particles. Earth’s magnetic field arises from movements in its liquid iron outer core, a process called a dynamo. However, larger rocky planets like super-Earths

Microgravity Spaceflight Causes Astronauts’ Brains to Shift and Deform

Astronomy, Planetary Science /

Spaceflight places significant physical strain on astronauts, leading to muscle loss, bone thinning, and fluid shifts. A new study in PNAS shows that microgravity also causes the brain to change shape. On Earth, gravity helps hold the brain in position, while surrounding cerebrospinal fluid cushions it. Scientists have long known that without gravity the brain

Researchers Determine How Much Faster Time Moves on Mars

Planetary Science, Space & Environment /

A study by two physicists at the U.S. National Institute of Standards and Technology (NIST) found that, on average, clocks on Mars run about 477 microseconds faster per day than those on Earth. Although this time difference remains extremely small, it can significantly impact efforts to synchronize clocks precisely between Earth, the Moon, and Mars.

EscaPADE Is Intended to Carry Out Research On Mars

Astronomy, Planetary Science /

On November 13, the Escape and Plasma Acceleration and Dynamic Explorers (EscaPADE) mission was launched into space aboard Blue Origin’s New Glenn rocket. EscaPADE is a NASA mission made up of two identical spacecraft, each roughly a meter in size, called Blue and Gold. Its mission is to investigate the magnetic and plasma environment surrounding

Meteorite Samples Are Time Capsules of The Early Solar System

Astronomy, Planetary Science, Space & Environment /

When a meteor flashes through the sky, it’s more than a striking sight—it’s nature delivering a time capsule to Earth. Inside are clues to the solar system’s earliest days and the processes that shaped planets, including our own. In a recent Space Science Reviews paper—soon to be included as a chapter in an upcoming textbook—Lawrence

Sake to the Stars: Japan Prepares to Launch its Lunar Brewing Experiment

Astronomy, Planetary Science /

They’re not serving sushi on the Moon—at least not yet—but when that day comes, Mitsubishi Heavy Industries and DASSAI want sake to be part of the menu. To move toward that goal, the two companies are launching a rice fermentation experiment aboard the International Space Station (ISS). One long-running joke of the Space Race was
