An international team of researchers led by astronomers from Leiden University (Netherlands) has produced the first sharp radio maps of the universe at low frequencies. Thanks to a new calibration technique, they bypassed the disturbances of the Earth’s ionosphere. They have used the new method to study plasmas from ancient black hole bursts. Potentially, the … Read more
The far side of the moon is a mysterious place that is never visible from the Earth. The most remarkable feature of the moon is its asymmetry between the lunar near side and far side in composition, crust thickness, and mare volcanism. Scientists have not yet reached a consensus on the origin of the lunar … Read more
MIT astronomers have observed the elusive starlight surrounding some of the earliest quasars in the universe. The distant signals, which trace back more than 13 billion years to the universe’s infancy, are revealing clues to how the very first black holes and galaxies evolved. Quasars are the blazing centers of active galaxies, which host an … Read more
The James Webb Space Telescope (JWST), a cutting-edge instrument in space exploration, has recently shed light on the mysteries of young stellar objects (YSOs) within the NGC 346 open cluster. Published on April 24 and available on the arXiv preprint server, the study conducted by an international team of astronomers presents invaluable insights into the … Read more
Dead stars known as white dwarfs, have a mass like the sun while being similar in size to Earth. They are common in our galaxy, as 97% of stars are white dwarfs. As stars reach the end of their lives, their cores collapse into the dense ball of a white dwarf, making our galaxy seem … Read more
On July 1, 2023, Euclid, a unique European space telescope was launched from Cape Canaveral. The launch was undoubtedly the highlight of my career as an astronomer, but witnessing the result of years of work being put on a rocket is not for the faint of heart. Following a perfect launch, Euclid swiftly arrived to … Read more
An asteroid dubbed “Lucy’s baby” after a NASA spacecraft discovered it is orbiting another asteroid last November is,, in fact,, a solar system toddler—just 2–3 million years old, a Cornell-led research team estimates using novel statistical calculations. The team derived the age of Selam, a “moonlet” circling the small asteroid Dinkinesh in the main asteroid … Read more
Over the course of its elliptical orbit, the moon Enceladus is squeezed unevenly by Saturn’s gravitational pull and deforms from a spherical shape into a football shape and back again. This cyclic stress causes a phenomenon called “tidal heating” within Enceladus and dissipates enough energy to maintain what is believed to be a global ocean … Read more
A team of astronomers and citizen scientists has discovered a planet in the habitable zone of an unusual star system, including two stars and potentially another exoplanet. The planet hunters spotted the Neptune-like planet as it crossed in front of its host star, temporarily dimming the star’s light in a way akin to a solar … Read more
Analyzing samples retrieved from the asteroid Ryugu by the Japanese Space Agency’s Hayabusa2 spacecraft has revealed new insights into the magnetic and physical bombardment environment of interplanetary space. The results of the study, carried out by Professor Yuki Kimura at Hokkaido University and co-workers at 13 other institutions in Japan, are published in the journal … Read more
