How Do Astronomers Think Saturn Generates its Internal Heat

Saturn internal heat Saturn’s internal heat has been puzzling astronomers since its discovery in the 18th century. Due to fundamental physics, anything with the tiniest bit of mass, including planets, will always emit thermal energy, which is also called thermal radiation. However, models predicted that Saturn’s internal heat should have…

Which of the following best summarizes what we mean by dark matter?

Dark matter is a mysterious substance that can be indirectly inferred to exist in the universe through gravity, but cannot be observed by any other means, including electromagnetic waves. Various hypotheses have been proposed, such as primordial black holes, inactive neutrinos, or even mass of quarks that remain unatomized, such…

Was there never a beginning to the universe?

The standard cosmological model (the so-called harmony) has a past singularity. This individuality represents a moment of time that marks the beginning of time itself (and the universe), although individuality is not part of the universe itself. There are alternative models in which the universe has no beginning. For example…

The Mystery of Jupiter’s powerful auroras finally solved

A recent study suggests that mysterious X-ray bursts from Jupiter’s auroras suggest that the big planet’s “northern lights” may have unexpected connections to Earth’s. In the north or south lights on earth, Auroras, shimmering displays of light are observed above the poles of several planets around the solar system. The…

Discovery of the Ultra-high energy gamma-ray Source in Deep Space

By examining the LHAASO-KM2A data of 308.33 life days, we discovered a UHE gamma-ray source, LHAASO J2108+5157. With 9.5 sigma and 8.5 sigmas, respectively, there is a significant excess of gamma-rays driven showers in both the 25–100 TeV and >100 TeV energy ranges. …
