Scientists discover Aurora-like Radio Emission above a Sunspot
Astronomers from New Jersey Institute of Technology’s Center for Solar-Terrestrial Research (NJIT-CSTR) published detailed radio observations of an extraordinary aurora-like display occurring 40,000 km above…
Calculating the Transparency of Saturn’s Rings using Eclipses
Using eclipses to calculate the transparency of Saturn’s rings entails studying how the rings block or transmit sunlight during a solar eclipse. Astronomers can observe…
Cataclysmic Variable Stars (CVs)
Cataclysmic variable stars (CVs) are binary star systems made up of a white dwarf and a companion star, most commonly a red dwarf. CVs are…
Gravitational Microlensing – an astronomical phenomenon
Einstein’s theory of general relativity predicts gravitational microlensing. Because of the gravitational lens effect, it is an astronomical phenomenon. It happens when the gravitational field of…
Phaethon’s Asteroid Composition
For a long time, researchers have been perplexed by the five-kilometer-diameter asteroid Phaethon. When the asteroid passes closest to the Sun during its orbit, a…
Brown Dwarf with the Smallest Free-floating Radius
Brown dwarfs are objects that exist on the border between stars and planets. They form in the same way that stars do, becoming dense enough…
A Sextuplet of Planets is revealed by an Astronomical Waltz
A key new system of six transiting planets orbiting a bright star in a harmonic rhythm has been discovered by an international collaboration of astronomers…
Giant Planets Cast a Lethal Pall
Massive gas planets can be agents of chaos, ensuring that nothing lives on their Earth-like neighbors in the vicinity of other stars. According to new…
Giant Reservations about Giant Exomoons
Only two of the more than 5300 known exoplanets have been found to have moons in orbit around them. For the first time, researchers discovered…
Time-domain Astronomy
Time-domain astronomy is a branch of astronomy that studies celestial objects and phenomena over time by observing changes in brightness or other properties. It is…
Oceans and Geysers may exist on some Icy Exoplanets
A new study broadens the search for life beyond our solar system by indicating that 17 exoplanets (worlds outside our solar system) may have oceans…
