For millennia, humans have seen inexplicable things in the sky. Some have been beautiful, some have been terrifying, and some — like auroras and solar eclipses before they were understood scientifically — have been both. Today’s aircraft, balloons, drones, satellites and more only increase the chances of spotting something confounding overhead. In the United States, […]

Some meteors leave trails lasting up to an hour. Now we may know why
To leave a lasting trail, meteors need to aim low. A new survey of shooting stars shows that meteors that blaze through 90 kilometers up in the sky leave a persistent afterglow, unlike those that burn up at greater heights. Meteors are normally blink-and-you’ll-miss-it events. A particle of space dust leaves a fiery trail of […]
Astronauts actually get stuck in space all the time
Imagine going on a weeklong business trip and not coming home until the following year. That may be the situation for U.S. astronauts Sunita Williams and Butch Wilmore, whose eight-day mission to the International Space Station has already stretched to more than two months and is likely to go even longer. The pair launched to […]
A medium-mass black hole has been spotted for the first time in our galaxy
Extreme Climate Survey Scientific news is collecting questions from readers about how to navigate our planet’s changing climate. What do you want to know about extreme heat and how it can lead to extreme weather events? Most black holes that astronomers have discovered fall into one of two categories. They are either stellar-mass black holes, […]
Sulfur was the key to the first water on Earth
Extreme Climate Survey Scientific news is collecting questions from readers about how to navigate our planet’s changing climate. What do you want to know about extreme heat and how it can lead to extreme weather events? “These two papers reinforce each other tremendously, and I think their story is becoming really compelling,” says Alessandro Morbidelli, […]
Jupiter’s Great Red Spot may be less than 200 years old
Extreme Climate Survey Scientific news is collecting questions from readers about how to navigate our planet’s changing climate. What do you want to know about extreme heat and how it can lead to extreme weather events? The Great Red Spot is the largest vortex in our solar system (SN: 12/12/17). Located in Jupiter’s southern hemisphere, […]
NASA persistence finds first possible hint of ancient life on Mars
Extreme Climate Survey Scientific news is collecting questions from readers about how to navigate our planet’s changing climate. What do you want to know about extreme heat and how it can lead to extreme weather events? This isn’t the first sign of organics on Mars – the Curiosity rover detected organic molecules in a region […]
Moonquakes are much more common than previously thought, Apollo data suggest
Extreme Climate Survey Scientific news is collecting questions from readers about how to navigate our planet’s changing climate. What do you want to know about extreme heat and how it can lead to extreme weather events? In the 1960s and 1970s, the Apollo missions that landed on the Moon carried two types of seismometers: one […]
Scientists want to send endangered species to the moon
As more and more species come close to extinction, scientists have been collecting samples of animals, plants and other creatures and storing them in biorepositories around the globe.SN: 5/8/19). But climate change, environmental disasters and wars threaten these modern Noah’s Arks (SN: 28/2/22). Now, a team of researchers is thinking of an out-of-this-world solution: building […]
A distant quasar may be circling all the galaxies around it
Extreme Climate Survey Scientific news is collecting questions from readers about how to navigate our planet’s changing climate. What do you want to know about extreme heat and how it can lead to extreme weather events? The quasar is so distant that its light took 13.0 billion years to reach us, so we see it […]
