In July 1969, humanity transitioned from the mundane into the realm of myth and legend. This moving tribute to the Apollo missions, narrated by the legendary Carl Sagan, reminds us that our greatest discovery on the Moon was actually a transformative new perspective on our own

🚨 The Snow Moon peaks today at 5:09 PM EST. Named for the heavy winter drifts, this "Bear Moon" shares the sky with a brilliant Jupiter tonight. Bundle up and find a clear view of the constellation Cancer!

🚨 Antarctica’s South Pole Telescope just caught a cosmic firework show! Powerful stellar flares are erupting near the Milky Way’s supermassive black hole. These outbursts make our Sun look like a flickering candle. We’re rewriting the models of our galaxy's center in real-time.

This 17th-century star atlas doesn't just map coordinates; it tells stories. From the "chained princess" Andromeda and the hero Perseus to the Great Bear (Ursa Major) roaming the north, these maps were the GPS of the ancient world. Before digital telescopes, this was how we

🚨 MISSION UPDATE: The journey back to the Moon reaches a critical milestone. @NASA has officially commenced the countdown for the @NASAArtemis rehearsal. Over the coming days, teams will conduct a full "wet dress" of the Space Launch System (SLS), fueling the rocket and

The 1576 diagram "A perfit description of the Cælestiall Orbes" changed everything for science. It was one of the first English maps of a heliocentric universe following Copernicus’ theory. Thomas Digges broke the traditional hard shell of the stars, illustrating them scattering

Witness the rare ghost lights of the upper atmosphere. This shot captures an event that lasts less than a millisecond. Recorded over Italy, the image features a Red Sprite and a circular ELVE appearing simultaneously. This is a rare occurrence where two distinct types of upper

After six months of meticulous research and design, artist Martin Vargic released "Exoplanet Zoo," a massive infographic featuring over 1,100 documented alien worlds. By blending artistic flair with rigorous scientific datasets, Vargic has created a visual census of the cosmos

Galileo’s drawings of the Moon was the first realistic images in history. This is the original sketches of the Moon, found in his manuscript for Sidereus Nuncius (The Starry Messenger), dated to around 1610.

However, transits don't occur every 243 years like clockwork; instead, they happen in a recurring pattern within that cycle: pairs of transits 8 years apart (e.g., 2004 and 2012), followed by a gap of about 105.5 years to the next pair (e.g., 2117 and 2125), then a longer gap of

Carl Sagan uses the story of two brothers to illustrate the "Paradox of Time Dilation." While one brother takes a short stroll at near-light speed, his internal clock and biological functions slow down so significantly that he ages only minutes while his brother ages decades.

VFTS 352 is a massive overcontact binary system 160,000 light-years away. These two stars orbit so closely that their surfaces overlap, sharing 30% of their material. They will eventually merge into one giant star or collapse into a pair of black holes. We are watching a

A size comparison between Pluto and Australia Pluto's diameter is about 2,370 km, while Australia's width is around 4,000 km, making Australia larger in linear size.

In these shots by J. Mccarthy, ISS transits both the Sun and the Moon at 17,500 mph. The entire transit lasts less than 0.5 seconds. The reason why the ISS keeps its relative size against both the Sun and the Moon is due to a remarkable coincidence: the diameter of the Moon is

In 2012, Venus crossed the face of the Sun for the last time in our lifetime. This rare orbital alignment happens in a pattern that repeats only every 243 years. Because of the tilt of the planetary orbits, the next transit won't occur until December 2117.
