Despite being so elusive, neutrinos are produced in abundance in some of the most violent events in the universe. One of their strangest properties is that they can spontaneously switch between three types, or “flavors”: a phenomenon known as neutrino oscillation that remains poorly understood in extreme astrophysical environments.

Researchers have developed a mathematical method that enables more precise calculations of the most economical travel routes between the orbits of celestial bodies. To demonstrate this method, they calculated a more efficient path between Earth’s and the moon’s orbits than any previously described in the scientific literature. The study is published in the journal Astrodynamics. […]

An international team of researchers has developed new stellar and supernova models to explain the mysterious elemental abundance patterns left by billions of supernova explosions around the Perseus constellation, which have been difficult to explain with conventional theoretical models, reports three recent studies published in The Astrophysical Journal.

Scientists have discovered a galaxy as it was 13 billion years ago, 800 million years after the Big Bang. It contains possible evidence of the universe’s first stars and is one of the most chemically primitive galaxies observed to date.

There’s a new space race to the moon, and this time the ambitions are not just to visit but to stay. NASA’s Artemis program aims to establish a long-term human presence on the lunar surface in the 2030s. China, India, Japan and a number of private companies all have lunar mission programs of their own. […]

Just a few hours before the Orion spacecraft crossed the sky en route to the moon on April 1, mechatronics engineer Rodrigo Trevisan Okamoto received confirmation he had been waiting for since the Artemis 2 mission was announced in 2023. The email from NASA stated that the crew of the first crewed mission to orbit […]
