Each year in mid-August, Earth plows through the debris stream of an enormous comet, creating the Perseids. 2023’s show will be magnificent!
Massive objects like black holes, stars, and rogue planets routinely pass near our Solar System. An ensuing comet storm could destroy us.
Each December, the Geminid meteor shower puts on a show for skywatchers across Earth. With a new Moon at 2023’s peak, it’ll be outstanding!
The detection of two celestial interlopers careening through our solar system has scientists eagerly anticipating more.
You can lead an overconfident chatbot to expert knowledge, but can it actually learn and assimilate new information?
Get ready for the most peculiar road trip that will help you understand the vastness and emptiness of the solar system — and Sweden.
Finding this missing piece of water’s path through the universe offers clues to how it came to be on Earth.
In 1054, a core-collapse supernova occurred 6500 light-years away. In 2023, JWST imaged the remnant, and might solve a massive mystery.
While humanity has been skywatching since ancient times, much of our cosmic understanding has come about only recently. Very recently.
Explore how the study of exoplanets is transforming our understanding of ocean formation.
Despite the vast number of planets in the Universe, Earth’s specific evolutionary history guarantees that its life forms — including humans — are utterly unique.
The recently discovered Oort cloud comet, Bernardinelli–Bernstein, has the largest known nucleus: 119 km. Here’s what it could do to Earth.
65 million years ago, a massive asteroid struck Earth. Not only did Jupiter not stop it, but it probably caused the impact itself.
Spaceguard shows that we can manage risks to the extinction of humanity — if only we put our mind to it.
Many impact craters on Earth have been erased thanks to wind, water, and plate tectonics. But scientists have clever ways to find them.
By looking down, scientists are looking back in time.
Our Solar System’s outer reaches, and what’s in them, was predicted long before the first Oort Cloud object was ever discovered.
The thrills and horrors of strange heavenly bodies condensed into one attractive snapshot.
A new study shows that the Bernardinelli-Bernstein Comet is much larger than previously thought — potentially the largest ever spotted.
Since dark matter eludes detection, the mission will target sources of light that are sensitive to it.
“When molecules misbehave, it can lead to great insight.”
This technological feat changes our cosmic history.
A study proposes that an ancient trading network, called the Hopewell tradition, may have been wiped out by what is known as a cosmic airburst.
It peaks the nights of August 11–13, but it’s no longer the year’s most reliable meteor shower. Every year, beginning in mid-July, planet Earth commences passing through an enormous debris […]
Invisible cloaks. Ghost imaging. Scientists are manipulating light in ways that were once only science fiction.
65 million years ago, an asteroid strike caused the 5th great mass extinction. Could we save Earth, today, from a similar event?
