Using NASA's Transiting Exoplanet Survey Satellite (TESS), European astronomers have discovered an eclipsing binary in the open cluster NGC 2232. The binary, designated TIC 43152097, is the first such system detected in this ...
By observing the night sky, medieval monks unwittingly recorded some of history's largest volcanic eruptions. An international team of researchers, led by the University of Geneva (UNIGE), drew on readings of 12th and 13th ...

Using data from NASA's TESS satellite, Chinese astronomers have investigated a binary star known as OO Dra. The study found that this object is an Algol-type binary that was formed as a result of an extremely helium-poor ...
The sun is the only star in our system. But many of the points of light in our night sky are not as lonely. By some estimates, more than three-quarters of all stars exist as binaries—with one companion—or in even more ...

Russian astronomer Valery Kozhevnikov has conducted photometric observations of the cataclysmic variable (CV) IPHAS J013031.89+622132.3 (J0130 for short), finding that the object exhibits deep eclipses. The discovery, presented ...
Using ESA's XMM-Newton and NASA's Swift spacecraft, astronomers have found that a hard X-ray source known as 2PBCJ0658.0-1746 is an eclipsing magnetic cataclysmic variable of the polar type. The finding, presented in a paper ...
For five months in mid 2017, Emily Mason did the same thing every day. Arriving to her office at NASA's Goddard Space Flight Center in Greenbelt, Maryland, she sat at her desk, opened up her computer, and stared at images ...

An international team of astronomers has observed a deep, day-long asymmetric occultation in a recently detected low-mass star known as EPIC 204376071. In a research paper published February 21 on arXiv.org, the scientists ...
An eclipse is an astronomical event that occurs when an astronomical object is temporarily obscured, either by passing into the shadow of another body or by having another body pass between it and the viewer. An eclipse is a type of syzygy.
The term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth-Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the shadow of another moon. A binary star system can also produce eclipses if the plane of the orbit of its constituent stars intersects the observer's position.
