Claude-Louis Mathieu, born in Macon, France, in 1783, demonstrated an early aptitude for mathematics, overcoming familial and financial obstacles to graduate from the Ecole Polytechnique in 1805. His ...

Dave Eicher, Editor Emeritus of *Astronomy* magazine, encourages observers to locate Saturn, the solar system's sixth planet, in the evening sky. During this observational period, Saturn's typically ...

I wake up to a chime from my smartphone. Bleary-eyed, I check it — and jolt awake upon seeing an automated email from the MeerKAT radio telescope in South Africa. The subject line reads: “AT 2018xxx ...

NGC 7789 is an open star cluster situated in Cassiopeia, discovered by Caroline Herschel in 1783, and is also known by appellations such as "Caroline’s Haystack." This celestial object is a relatively ...

On November 22, Titan will transit Saturn. The Silver Sliver Galaxy (NGC 891), an edge-on spiral measuring 13’ by 3’ and glowing at magnitude 9.9, is observable 3.5° east of Almach (Gamma Andromedae) ...

Apollo mission lunar samples provided crucial data, initially intended to test existing Moon formation theories (capture, co-formation, fission), but ultimately leading to the development of the Giant ...

Black holes are regions of spacetime with gravity so strong that nothing escapes. Black holes grow by consuming nearby matter, slowing their eventual evaporation. Hawking radiation causes black holes ...

Several planets, including Mercury, Mars, Venus, Uranus, Neptune, Saturn, and Jupiter, are visible this month. Saturn's moon Titan will cast its shadow on Saturn twice during July. Neptune will be ...

Stars move slowly across the sky over very long periods. The closer a star is, the more easily we can see its movement. Stellar parallax is a shift in a star's apparent position due to Earth's orbit.

The existence of "Planet Nine," a hypothetical planet in the outer solar system, is supported by indirect evidence such as the unusual clustering of orbits of extreme trans-Neptunian objects (ETNOs) ...

Manual cardiopulmonary resuscitation (CPR) techniques, including the "handstand" method, are ineffective in microgravity due to the lack of a counter-force to compression, resulting in insufficient ...

The article outlines a series of observational opportunities for planets, including Jupiter's Galilean moon shadow transits, close approaches of the Moon with Venus, Mercury, and Mars in the predawn ...
