Protostars ‘sneeze’ and produce rings of gas and magnetic flux as they grow

Researchers have uncovered new insights into the early development of baby stars. As published in The Astrophysical Journal Letters, a research team from Kyushu University and Kagawa University reports that during the early growth period of a baby star, the protostellar disk—the dense disk of gas and dust that surrounds the star—expels magnetic flux and […]

NASA’s Artemis II mission launches on first crewed lunar flyby in 50 years

Mercury scout mission concept with solar sail propulsion

The planet Mercury is the closest planet to the sun, and also the most difficult for spacecraft to visit and explore. This is because as spacecraft get closer to Mercury, the sun’s enormous gravity pulls in the spacecraft, greatly increasing its speed and making it hard to slow down without large amounts of fuel. But […]

Gravitational waves suggest a ‘forbidden zone’ for stellar-origin black holes

An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light on one of the most cataclysmic events in the universe. At the end of their lives, most massive stars collapse into black holes—objects with gravity so strong that not even light can escape.

Gemini South confirms long-suspected link between the composition of exoplanets and their host stars

Astronomers have discovered that a giant planet, WASP-189b, echoes the composition of its host star, providing the first direct evidence of a foundational concept in astrobiology. This discovery was achieved through the first-ever simultaneous measurement of gaseous magnesium and silicon in a planet’s atmosphere. The team used the Gemini South telescope, one half of the […]

Q&A: What to know about NASA’s first crewed moon landing since 1972

Artemis II, NASA’s first crewed mission to the moon in more than 50 years, represents a shift from short visits toward sustained exploration, where understanding lunar geology and resources becomes as important as the engineering that gets astronauts there. Artemis II is currently scheduled to launch Wednesday, April 1, at 6:24 p.m. EDT, with backup […]

High nickel concentrations in Martian bedrock point to potential biosignatures

In 2024, NASA’s Perseverance rover found surprising levels of Nickel in the Martian bedrock of an ancient river channel, called Neretva Vallis, which flowed into the Jezero crater. A new study, published in Nature Communications, has taken a closer look at the data collected from the region and researchers are seeing what could be remnants […]

SpaceX files to go public, paving way for record stock offering

Cosmic collision of galaxies mapped by Maunakea telescope

An astronomer at the University of Hawaiʻi at Hilo is using data from the Canada–France–Hawaiʻi Telescope (CFHT) on Maunakea to help reconstruct a slow-motion cosmic collision, one that has been unfolding for hundreds of millions of years. A new study from principal investigator R. Pierre Martin, a professor of astronomy at UH Hilo, and international […]

What it takes to keep astronauts safe in deep space

The Artemis II mission launches this week as a first step toward returning to the moon and reaching Mars. Materials scientist Debbie Senesky explains the material tech that makes these missions possible.
