Physicists are closer than ever to answering fundamental questions about the origins of the universe by learning more about its tiniest particles. University of Cincinnati Professor Alexandre Sousa in a new paper outlined the next 10 years of global research... Continue Reading →
Are Saturn's auroras like Earth's? To help answer this question, the Hubble Space Telescope and the Cassini spacecraft monitored Saturn's North Pole simultaneously during Cassini's final orbits around the gas giant in September 2017. During this time, Saturn's tilt caused its North Pole to be clearly visible from Earth.... Continue Reading →
Jupiter looks sharp in these two rooftop telescope images. Both were captured last year on November 17 from Singapore, planet Earth, about two weeks after Jupiter's 2023 opposition. Climbing high in midnight skies the giant planet was a mere 33.4 light-minutes from... Continue Reading →
One of the most identifiable nebulas in the sky, the Horsehead Nebula in Orion, is part of a large, dark, molecular cloud. Also known as Barnard 33, the unusual shape was first discovered on a photographic plate in the late 1800s. The red glow originates from hydrogen gas predominantly behind the nebula,...

The Sun, our life-sustaining star, is not just a serene orb of light but an immense, dynamic sphere of energy with a profoundly complex magnetic field. Among its many phenomena, solar flares stand out as some of the most dramatic... Continue Reading →
This galaxy is unusual for how many stars it seems that you can see. Stars are so abundantly evident in this deep exposure of the spiral galaxy NGC 300 because so many of these stars are bright blue and grouped into resolvable bright star... Continue Reading →
The researchers say their findings, published in Nature, provide insight into the role of sleep, but still leave an open question around what function the latter half of a night’s sleep serves. The researchers say the study supports the Synaptic Homeostasis... Continue Reading →
Sailing through space might sound like something out of science fiction, but the concept is no longer limited to books or the big screen. A next-generation solar sail technology – known as the Advanced Composite Solar Sail System – will launch aboard... Continue Reading →
Problem:Irodov, problem 1.52., it says that acceleration is constant in magnitude and pointing permanently towards the center of the wheel. `vrai ou faux? A wheel rolls on a horizontal surface without slipping. Also rolling is the acceleration vector (red). It... Continue Reading →
