Astronomers worldwide have issued a warning about an imposing celestial object known as '2013 NK4', set to make a close approach to Earth. According to reports from Earth Sky, this significant space rock, with a diameter of approximately 2000 feet, is expected to be visible through a small telescope as it passes at a distance eight times that between Earth and the Moon.

Much like the Moon is to Earth, many planets are tidally locked to their suns, meaning that the planet takes the same amount of time to spin on its axis as it does to orbit the sun

Astronomers have found three previously unknown moons in our solar system, two additional moons circling Neptune and one around Uranus.

The distant tiny moons were spotted using powerful land-based telescopes in Hawaii and Chile, and announced Friday by the International Astronomical Union's Minor Planet Center.

The latest tally puts Neptune at 16 known moons and Uranus at 28.

The study suggests the Earth’s core may be leaking the rare helium, upheaving the belief that the giant ball of molten iron at the center of our planet is sealed away

Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago.

A new analysis of chaos in the solar system reveals how planetary collisions are avoided over billions of years.

Some have managed to record this unique phenomenon.
Professor Vladan Duci, Ph.D., noted that as a professional who studies these phenomena, nothing is unusual for him, and that the aurora borealis over Belgrade could be seen in 2000, on April 6 and 7.

A stunning natural spectacle graced the skies of Bulgaria recently, as the Northern Lights, or aurora borealis, danced over several cities. This awe-inspiring event, which occurs only rarely in the region, was the result of a solar flare that took place on November 3.

For the first time, the Northern Lights became visible in almost the entire Europe
