Voyager mission's Golden Record captures Earth’s essence for alien discovery

Voyager carries Earth's hopeful greeting into deep space as a message of peace

Along with scientific instruments, each Voyager carried a golden record containing multilingual greetings—ranging from Sumerian and Akkadian to Thai and Cantonese—music, and sounds of Earth intended for any intelligent life that might find it.

NASA designed the Golden Record using hydrogen to ensure it's universally readable

The Golden Record holds what is essentially a human "time capsule," featuring music, nature sounds, and greetings from around the world. NASA used the radiation period of hydrogen's simplest transition as a baseline to convey timing and structure. The first coded image is included on the cover as a test so aliens can check if they decoded it correctly.

Voyager spacecraft defied expectations and only powered down after 47 years in space

Originally built for a four-year mission, Voyagers 1 and 2 used a rare planetary alignment and gravity assists to reach interstellar space. With limited power and aging systems, they will continue to send data until the mid-2030s. (Some readers may experience a paywall.)

Voyager 1 captured Earth as a 'Pale Blue Dot' from 6 billion kilometers away

On Feb. 14, 1990, NASA's Voyager 1 space probe took the farthest photo of Earth ever captured. Earth appears so small in the image that it takes up less than a single pixel out of 640,000 in the photo's frame.

After NASA's Voyager 1 captured Earth as a single pixel as it left the solar system in 1990, astronomer Carl Sagan used the image to reflect on humanity's fragility and the responsibility to protect 'the only world we've ever known.'

Planetary exploration and the search for extraterrestrial life kicked off with Viking

NASA's Viking 1 and 2 missions revealed Mars' geological activity and potential for past life through their evidence of past surface water. Viking 1 held the record for the longest Mars surface operation until the Opportunity rover surpassed it in 2010.

This archive includes the many steps it took to put together each Voyager probe. Photos focus on individual parts, like the 8-track tape deck, the large dish-shaped antenna, and its long arm magnetometer boom.

Voyager Station, the world's first space hotel, is planned for 2027

The structure spans 488 meters in diameter and will rotate to simulate one-sixth of Earth's gravity while circumnavigating the planet every 90 minutes. The Voyager Station is designed to accommodate 450 guests and 150 crew members, providing amenities such as restaurants, a sports hall, and a movie theater.

Space archaeology studies space trash in the context of heritage and social meaning

Some orbiting objects, such as Elon Musk's Tesla, have symbolic or historical importance, despite being functionally worthless. The oldest human-made object in Earth's orbit is Vanguard 1, a grapefruit-sized satellite launched in 1958. The strangest may be an experimental, inflatable space station containing live cockroaches.

Quantum mechanics-based technology may explain the Fermi paradox

It describes the discrepancy between the high likelihood of life beyond Earth given the vastness of the universe and the lack of evidence for such life, since extraterrestrial civilizations have not communicated with us. However, quantum communication—a more information-dense and effective method than classical means—requires massive receivers and very narrow signals, which would easily miss Earth, making a lack of signals expected.

Visualizing the history of Saturn and its rings

Every 13 to 16 years, Saturn's rings become far less visible because its plane becomes exactly even with Earth's. This visual-rich essay explores the history of humanity's perception of Saturn, from Galileo's first sighting (and dubbing the rings "ears") to the idea that the rings won't last more than a few hundred millions years more. Explore this fascinating planet here.

World War II soldiers received specially-made vinyl records

Comets serve as time capsules of the early solar system

The frozen objects preserve the molecular composition of the solar system's formation, dating back about 4.6 billion years. Spectral analysis of the gases they release when heated upon approaching the sun in eccentric orbits reveals this composition and helps assess solar system formation models.

The fortunate factors that make life on Earth possible

The Earth is teeming with life while all the other exoplanets and planets aren't. A very specific set of aligned factors forms the habitability of our planet, and without just one of these fortunate factors, we might not be here. This piece lists...

The origins of our fascination with time travel

Humans have been captivated by the prospect of leaping forward and backward in time for thousands of years. Georgia Institute of Technology Science Fiction Studies Professor Lisa Yaszek recounts how the concept has been utilized by storytellers from 400 BCE to modern-day to explore our relationship with the supernatural, technology, and the past. In a way, this historical recounting is a journey through time.

The psychedelic playlist inspired by a Johns Hopkins experiment

Dating back to 1967, the playlist is over seven hours long and organized in such a manner as to echo users’ experiences as their trips rise, crest, and fall. According to the initial creator of the playlist, the music is a “nonverbal support system” that keeps users from prematurely returning to normal consciousness.

Once whale songs were discovered, conservation efforts boomed

Until the 1950s, humans believed whales were mute. Once American underwater surveillance systems caught their sounds during the Cold War, the perception of the creatures changed, leading humans to campaign for whaling bans and long-term conservation efforts. These captivating whale songs can be heard throughout the ocean.
