A Full Moon occurs when the Earth is between the Sun and the Moon. The Moon's orbit creates different phases, including a Full Moon. Full Moons have traditional names, like the Sturgeon Moon. The 2025 ...

The Sun's surface is a turbulent mix of superheated gas. If sound could travel through space, the Sun would sound like a constant, loud roar. This roar would be caused by massive movements of hot gas ...

August 2025 offers several planetary conjunctions, including a close approach of Venus and Jupiter on August 12th, and a second conjunction of Saturn and Neptune on August 6th, with a third occurring ...

Current satellite operational paradigms result in decommissioning spacecraft when they malfunction or run out of fuel, despite potentially functional components, leading to significant financial and ...

The origin of Earth's water is a long-standing scientific question, with differing isotopic ratios of deuterium to hydrogen (D/H) in Earth's oceans compared to the early solar system suggesting ...

The universe began with an unimaginably hot, dense state. Inflation rapidly expanded the universe's size. Before inflation, the universe existed in a period called the GUT era where forces were ...

The aurora borealis, or Northern Lights, is caused by solar wind particles colliding with Earth's atmosphere. Ancient Chinese texts describe a five-colored aurora event dating back to around 977 or ...

The Sun emits electromagnetic radiation across a broad spectrum, including visible, infrared, microwave, radio, ultraviolet, X-ray, and gamma-ray wavelengths. Visible light, comprising wavelengths ...

Asterisms are informal stellar groupings, formally distinguished from the 88 International Astronomical Union (IAU) constellations in 1928 with Eugène Joseph Delporte's publication, which defined ...

The universe's expansion is accelerating, a phenomenon attributed to dark energy, potentially explained by a cosmological constant (Λ) in Einstein's general relativity. The ΛCDM model, the standard ...

The Big Dipper, an asterism within the Ursa Major constellation, is readily observable from mid-to-high northern latitudes and its appearance varies throughout the year due to Earth's orbit and ...
