SAEDNEWS: NASA’s Picture of the Day Captures Mars Disappearing Behind the Wolf Moon
According to Saed News’ science desk, an occultation in astronomy refers to the event when one celestial body is hidden from view by another passing object. Simply put, an occultation occurs whenever, from an observer’s perspective on Earth, a larger-appearing celestial object passes in front of a smaller-appearing one.
Due to its orbital motion, the Moon occasionally passes in front of all the planets in the solar system. This phenomenon occurs when the orbital planes of the Moon and the planets temporarily align.
Occultations offer captivating visual experiences. These events are especially striking when an outer planet, like Mars, is near its brightest and closest approach to Earth, creating unique moments for astronomers and astrophotographers.
NASA’s Astronomy Picture of the Day recently showcased Mars being occulted by the January Wolf Moon. Such occultations are rare, and a skilled photographer managed to capture this fleeting celestial alignment.
The event occurred yesterday and was visible from parts of North America and western Africa.
On January 15, the Moon was full, known as the Wolf Moon. This name refers to the first full moon of January, which in Native American tradition is associated with the howling of wolves on cold winter nights.
Observers noted that Mars’ occultation behind the Moon was clearly visible because the Moon was full and Mars was near opposition. During this opposition, which took place on January 16, Mars was at its closest distance to Earth in its orbit, appearing largest and brightest in the sky. The occultation lasted approximately one hour.
NASA’s image was captured near Chicago. At the time, the Moon, from the perspective of an Earth-bound observer, was moving angularly away from the Red Planet. Mars remained clearly visible, offering a rare opportunity for astronomy enthusiasts and night-sky photographers.
The Moon will pass in front of Mars again on February 9, providing another chance to witness this striking astronomical event.
