Everything we observe beyond our Local Group is speeding away from us, omnidirectionally. If the Universe is expanding, where is the center?
The contact binary system KIC 9832227 is worth another look. Astronomers have seen some incredible occurrences across space and time. The nova of the star GK Persei, shown here in an […]
The study shows that it’s possible to map the wildly subjective psychedelic experiences to specific brain regions.
Since the time of Galileo, Saturn’s rings have remained an unexplained mystery. A new idea may have finally solved the longstanding puzzle.
Our Sun will continue to grow, becoming a red giant and then a planetary nebula. Here’s how large it will get.
The “first cause” problem may forever remain unsolved, as it doesn’t fit with the way we do science.
Astronomers possibly solve the mystery of how the enormous Oort cloud, with over 100 billion comet-like objects, was formed.
Over the coming decades, over 100,000 new satellites are expected. For countless millennia, whenever we were faced with a clear, cloudless, moonless night, all of humanity was able to witness […]
Astrophysicists once believed in a static Universe, containing only the Milky Way galaxy. Science definitively proved otherwise.
There are pros and cons to sending interstellar messages to aliens that may or may not exist.
If humanity lives in an otherwise barren Universe, we’ll have to forge philosophy that fills the void.
Investments in public libraries are a long-term investment in children and communities.
When three wise men gifted baby Jesus with gold, frankincense, and myrrh, they had no idea one was made from colliding neutron stars.
Whether they’re gas giants or rocky planets makes all the difference for life. Over the past 30 years, we went from not knowing if there were planets like ours around other […]
Our Solar System’s outer reaches, and what’s in them, was predicted long before the first Oort Cloud object was ever discovered.
Even with all the recent impacts we’ve seen, it might be more “foe” than “friend” to us.
After more than two decades of precision measurements, we’ve now reached the “gold standard” for how the pieces don’t fit.
The thrills and horrors of strange heavenly bodies condensed into one attractive snapshot.
Just 12 million light-years away, the galaxies Messier 81 and 82 offer a nearby preview of the Milky Way-Andromeda merger.
One image can give over 100 times the data we now get from Hubble. NASA’s Hubble Space Telescope, launched in 1990, revealed the previously unseen Universe. The most distant galaxy ever […]
Achieving values and pursuing growth is the real secret to a fulfilled life.
When stars form, they emit energetic radiation that boils gas away. But it can’t stop gravitational collapse from making even newer stars.
The Earth that exists today wasn’t formed simultaneously with the Sun and the other planets. In some ways, we’re quite a latecomer.
The search for worlds outside our solar system has just turned up a planet, TOI-2257 b, with a truly extreme orbit.
65 million years ago, an asteroid strike caused the 5th great mass extinction. Could we save Earth, today, from a similar event?
There are ~400 billion stars in the Milky Way, and ~2 trillion galaxies in the visible Universe. But what if we aren’t typical?
The Copernican principle states that Earth is an ordinary planet, but that does not mean that life is ordinary in the universe.
Back during the hot Big Bang, it wasn’t just charged particles and photons that were created, but also neutrinos. Where are they now?
