Astronomers have made significant breakthroughs in understanding the surface features of distant stars, including the red giant Betelgeuse. Using high-speed photography and modern data processing, scientists have been able to suppress the effects of star twinkling, revealing large-scale hot and cold regions that may be convection currents in the star’s atmosphere. Recent observations have confirmed…

Scientists have made significant progress in unraveling the mysteries of the sun during the total solar eclipse that swept across the United States on April 8, 2024. The event provided a unique opportunity for researchers to study the sun’s corona, ionosphere, and gravity waves. Preliminary results from various experiments have shed light on the sun’s…
The Perseverance Rover on Mars has made a groundbreaking discovery, uncovering the oldest rocks humans have ever seen and potentially evidence of a new setting that ancient Martian organisms could have inhabited. The rover has been exploring the Jezero Crater and has found rocks that are likely older than 4 billion years, making them the…
A groundbreaking discovery in Kenya has shed new light on the lives of our ancient ancestors. The fossilized footprints of two ancient species, Homo erectus and Paranthropus boisei, have been found at the Koobi Fora site, dating back 1.5 million years. This remarkable find provides the first direct evidence of different archaic human species coexisting…
Science News has compiled a list of the best science books of 2024, covering a wide range of topics from the human experience to the challenges facing our planet. The books on this list offer thought-provoking insights into the world we live in and the potential solutions to the problems we face. From the preservation…
A recent study by the High Energy Stereoscopic System (HESS) collaboration has confirmed the existence of a “cooling break” in the energy spectrum of cosmic ray electrons and positrons at around 1 TeV. The research, published in Physical Review Letters, suggests that the origins of these particles are still hotly debated, with possible explanations including…
A team of researchers from the USA and India has developed a mathematical model to investigate the complex relationship between exercise, immune function, and cancer. The model reveals that increasing exercise intensity and duration leads to greater and sustained tumour suppression, offering valuable insights into how exercise can influence immune responses and potentially guide cancer…
Astronomers have made a groundbreaking discovery by detecting an astrosphere around a star similar to the sun. The astrosphere is a bubble of hot gas blown by a star’s stellar wind, which marks the edge of the solar system and protects planets from high-energy cosmic rays. This finding is significant as it provides insight into…
A pair of European Space Agency spacecraft, Proba-3, has been launched to create hundreds of artificial solar eclipses in orbit. This mission will allow scientists to study the elusive middle part of the sun’s atmosphere, which holds many of the sun’s most enduring mysteries. The satellites will fly together in lockstep, blocking the sun from…
A team of researchers has developed a groundbreaking new imaging technique that can reconstruct 2D radio images into 3D ones, providing a more accurate understanding of structures such as jet-like features streaming out of galactic black holes. This technique could challenge current physical models of how radio galaxies formed and has the potential to revolutionize…
