by Wei Lifigures by Catherine Ding The universe is massive, with an estimated 70 quintillion planets—that is 70 followed by an additional 18 zeros. In the Milky Way alone, where we reside, there are billions of planets. With these huge numbers, Earth seems very insignificant in the grand scheme of things. This raises the question: are we truly alone in this vast space of the … Continue reading Finding Life in Space: Why are we so special?
Jupiter’s moon Europa might not need the sun’s rays to glow. If so, its color will shed light on the chemistry of the ocean world. Continue reading Europa’s Glowing Ice Could Shine Light on the Moon’s Subterranean Secrets
A team of international astronomers have identified the smallest free-floating “rogue” planet observed to date. Continue reading Going Rogue in Space
Astrobiologists have discovered a way for exposed bacteria to survive voyages through space, giving them the potential to spread life throughout the universe. Continue reading Bacteria May Have Figured Out Space Travel
Researchers create a melanin particle containing selenium, providing even more protection from harsh UV rays. These nanoparticles can be incorporated into clothing – providing astronauts a very lightweight alternative to lead shielding. Continue reading Artificial Sunscreen Protects Cells from X-ray Radiation
Researchers have discovered a mysterious, repeating pattern of fast radio bursts from space – and no one knows where they are coming from. Continue reading Mysterious Pattern of Fast Radio Bursts Detected in Space
by Christopher Rota figures by Hannah Zucker When the first Apollo program astronauts set foot on the Moon in 1969, their footsteps inspired a generation. This opened a new realm of possibility for what humans can achieve with the necessary motivation and resources. Now, just over 50 years later, the National Aeronautics and Space Administration (NASA) has put the wheels in motion to lay down a fresh … Continue reading Should We Help NASA “Shoot for the Moon” Again?
Data from the New Horizons probe, flying in the asteroid field far beyond Pluto, have finally been downloaded and analyzed. They challenge our previous views of the formation of the solar system. Continue reading Fly-by of a distant asteroid provides clues about the formation of our solar system
Curiosity rover’s analysis of rocks on Mars suggests that ancient water on the red planet would have been suitable for supporting life. Continue reading Water on Mars Was Similar To Water on Earth
