A total solar eclipse occurs when the Moon passes directly between the Sun and Earth, fully blocking the Sun’s disk for observers within the narrow path of the Moon’s shadow...

Saturn images from telescope reveal intricate banding, the Cassini Division, and often the planet’s largest moon, Titan, in a single field. Achieving sharp, detailed views dep...

Planets often appear brighter and steadier than stars because they are closer objects that reflect sunlight over a small, steady area in the sky, while stars are so distant that...

A solar eclipse happens when the Moon passes between Earth and the Sun, briefly blocking some or all of the Sun’s light from reaching a narrow path on Earth. A lunar eclipse o...

An opposition occurs when a planet and the Sun appear on opposite sides of Earth, placing the planet opposite the Sun in our sky. For Mars and Jupiter, each has its own regular...

Buzz Aldrin did not go to Mars. He walked on the Moon as Lunar Module Pilot of Apollo 11 in July 1969 and later commanded Apollo 14 in February 1971. While Aldrin has advocated...

A planetary alignment happens when multiple planets appear near the same area of the sky from Earth’s perspective. In 2025, several groupings will occur, ranging from modest c...

In Florida, a meteor is a streak of light produced when space debris burns up in Earth’s atmosphere above the state, commonly visible in evening skies near coastlines or durin...

The planet next to the moon tonight depends on where the Moon lies in its 27.3-day orbit and which of the bright planets—Venus, Mars, Jupiter, or Saturn—is currently positio...

In this image from the James Webb Space Telescope, Saturn dominates the frame with its cooler, darker rings and subtle atmospheric details. The picture was captured by the Near-...

The Moon is Earth’s only natural satellite and its nearest celestial neighbor. Its mean distance from Earth is about 384,400 km, and it takes roughly 27.3 days to complete one...

Mars is currently traveling through the inner solar system along its elliptical orbit, and its nightly position in your sky depends on Earth’s rotation, Mars’s orbital motio...

Neptune is the eighth planet from the Sun, making it the outermost classical planet in our solar system. It orbits the Sun at an average distance of about 30 astronomical units...

A planetary alignment occurs when multiple planets appear within the same region of the sky from Earth’s perspective. In astronomy, this is primarily a geometry effect involvi...

Neptune’s auroras are dynamic glows of light near the planet’s magnetic poles, produced when solar wind and interstellar plasma interact with its magnetic field and atmosphe...

The Strawberry Moon is the June full moon, named by Indigenous and colonial traditions for the short harvest season of strawberries in North America. It is not a supermoon or an...

In 2026, Jupiter reaches opposition and its closest approach to Earth on Thursday, November 26, 2026 , at approximately 08:00 UTC. Opposition occurs when Earth sits directly bet...

Apophis is a near-Earth asteroid that will make several close approaches this century, with the most notable in 2029 and 2036. Where will Apophis be visible? During its historic...
