Dragonfly mission begins rotorcraft integration, testing stage

Dragonfly integration and testing—the activities involved in assembling the mission’s rotorcraft lander and testing it for the rigors of launch and extreme conditions of space—is officially underway in clean rooms and control rooms at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland.

A 100-solar-mass black hole merger ripples spacetime, and may flash in gamma rays

An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger discovery. In November 2024, the LIGO-Virgo-KAGRA observatories detected gravitational waves from a binary black hole merger, designated S241125n. Remarkably, just seconds later, satellites recorded a short gamma-ray burst (GRB) from the same region of the sky.

This isn’t just another rocky world orbiting a red dwarf—this one’s special

Astronomers have found an exoplanet that could serve as a benchmark in future studies. It’s a rocky planet orbiting an M-type star, and though these planets are plentiful, this one could serve as a benchmark for understanding other M-dwarf exoplanets and their atmospheres. According to the authors of a new study, this new exoplanet could […]

Safer space travel: Scientists create a cosmic ray simulator

Cosmic rays are one of the greatest challenges for space travel and pose a considerable risk to humans and materials. For the first time on European soil, an international research team in collaboration with the European Space Agency (ESA) has succeeded in providing a simulator for galactic cosmic rays at the GSI/FAIR accelerator facility in […]

Galactic islands of tranquility: ‘Little red dots’ may have brewed life’s building blocks

Astronomers have found that both the core of our Milky Way and the earliest proto-galaxies in the universe share a surprising trait: They are unusually calm and quiet in terms of harsh radiation. This tranquility is not just a cosmic curiosity; it may be essential for forming complex molecules that provide the ingredients of life. […]

AI accelerates elucidation of nuclear forces with explosive neutron star data

A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest building blocks in nature: atomic nuclei. In new research published in Nature Communications, the team uses machine learning and artificial intelligence to decipher the data from astrophysical observations to better understand how neutrons and protons interact […]

Webb spots details in nearby spiral galaxy NGC 5134

Two powerful instruments of the NASA/ESA/CSA James Webb Space Telescope joined forces to create this scenic galaxy view. This spiral galaxy is named NGC 5134, and it is located 65 million light-years away in the constellation Virgo. Though 65 million light-years may seem like a huge distance—the light that Webb collected to create this image […]

Deep underground, a telescope may soon detect ghosts of stars that died before Earth existed

Imagine looking up at the night sky and seeing a star suddenly burst into a blaze of light brighter than anything nearby. A flash so bright that it briefly outshines an entire galaxy before fading forever.

‘Ionic liquids’ could redefine the habitable zone

“Follow the water” has been a guiding mantra of astrobiology, and even space exploration more generally, for decades. If you want to find life, it makes sense to look for the universal solvent that almost all types of life on Earth use. But what if life doesn’t actually need water to live or even evolve? […]

NASA’s tiny spacecraft sends first exoplanet images

With the first images from the spacecraft now in hand, the team behind NASA’s Star-Planet Activity Research CubeSat, or SPARCS, is ready to begin charting the energetic lives of the galaxy’s most common stars to help answer one of humanity’s most profound questions: Which distant worlds beyond our solar system might be habitable?

NASA plans to have a permanent base on the moon by 2030: How it can be done

A US Senate committee has directed NASA to begin work on a moon base “as soon as is practicable.” Under legislation advanced by the Senate lawmakers, the outpost would serve as a science laboratory and proving ground, where astronauts would develop the capabilities to live and work beyond Earth’s orbit.

Astronomers discuss fortifying our planetary defenses

When people think of asteroids, they tend to picture rare, civilization-ending impacts like those depicted in movies such as “Armageddon.” In reality, the asteroids most likely to affect modern society are much smaller. While kilometer-scale impacts occur only every tens of millions of years, decameter-scale (building-sized) objects strike Earth far more frequently: roughly every couple […]

We are not alone: Our sun escaped together with stellar ‘twins’ from galaxy center

Researchers have uncovered evidence for our sun joining a mass migration of similar “twins” leaving the core regions of our galaxy, 4 to 6 billion years ago. The team created and studied an unprecedentedly accurate catalog of stars and their properties using data from the European Space Agency’s Gaia satellite. Their discovery sheds light on […]
