NOAA’s GOES-19 Satellite Records Rare Eclipse With Distorted Lunar Path
On Sept. 21, 2025, GOES-19’s CCOR-1 coronagraph recorded a natural lunar eclipse. The Moon’s trajectory appeared curved due to a satellite yaw-flip. Unlike L1-based coronagraphs, GOES-19’s orbit enabled this rare capture, helping scientists refine imaging systems and improve understanding of the Sun’s corona.

Exoplanets Explained: How Astronomers Find Worlds Orbiting Stars Beyond the Sun
Exoplanets are planets orbiting stars outside our solar system, hidden by stellar glare and detected indirectly. Astronomers identify them by tracking star wobbles or dips in brightness during planetary transits. NASA’s Kepler mission revealed thousands, with TESS now expanding the search. These discoveries confirm that planetary systems are abun...

Astronomers Solve Betelgeuse’s 6-Year Dimming Mystery by Spotting Secret Companion Star
Astronomers have finally spotted Betelgeuse’s hidden companion star, ending a 1,000-year mystery about its six-year dimming cycle. Using Gemini North’s advanced imaging, researchers captured the first image of the elusive companion orbiting deep within Betelgeuse’s atmosphere. The discovery solves a stellar puzzle and offers new insight into ...

Uranus Found Emitting Internal Heat, Reviving Hopes for Flagship NASA Mission
Astronomers have discovered that Uranus emits 12% more heat than it receives from sunlight, contradicting past data from Voyager 2. The internal warmth likely comes from leftover energy in the planet’s core, offering clues to its tilt and interior structure. This unexpected heat has intensified calls for a flagship NASA mission to Uranus. Scienti...

ESO Captures Clear Images of Interstellar Comet 3I/ATLAS Using VLT
The European Southern Observatory’s Very Large Telescope has captured the clearest images so far of comet 3I/ATLAS, an interstellar visitor first spotted on July 1, 2025. Identified by its hyperbolic orbit, the comet is only the third interstellar object recorded passing through our solar system. The VLT’s deep image and timelapse confirm it is...

New Dwarf Planet Discovery Challenges Planet Nine Hypothesis
The discovery of a potential dwarf planet, 2017 OF201, in the farthest reaches of the solar system is reshaping our understanding of space. With a highly elongated orbit and large size, it contradicts the Planet Nine hypothesis, which predicted orbital clustering among distant objects. This finding not only questions the existence of a ninth planet...
