Red dwarf stars were supposed to be inhospitable. But TOI-700, now with at least two potentially habitable worlds, is quite the exception.

Both made monumental contributions that were far ahead of their time. It’s hard to believe, but the idea that the Universe was dominated not by normal matter but rather by dark […]
The image you’re seeing isn’t a hole in the Universe, and the cosmic voids that do exist aren’t hole-like at all.
Your life’s memories could, in principle, be stored in the universe’s structure.
Jupiter’s atmosphere is hotter than it should be, and now we know why.
Without modularization, many epic projects simply would be impossible.
Every star we can see, including our sun, was born in one of these violent clouds.
We should all pause to appreciate the awe-inspiring beauty of the Universe.
Our understanding always will remain incomplete.
For the past 150+ years, the big ones have all missed us. But at some point, our good luck will run out.
Can two planets stably share the same orbit? Conventional wisdom says no, but a look at Saturn’s moons might tell a different story.
An artist’s impression of what the fully-deployed James Webb Space telescope will look like from the perspective of an observer on the ‘dark’ (non-Sun-facing) side of the observatory. (NORTHRUP GRUMMAN) […]
How scientists found out that we live in a cosmic aquarium.
The research suggests that roughly 1 percent of galaxy clusters look atypical and can be easily misidentified.
Shooting star or piece of space dust?
Saturn’s Iapetus, discovered way back in 1671, has three bizarre features that science still can’t fully explain.
Cosmologists are largely still in the dark about the forces that drive the Universe.
Tiny fluctuations in old Kepler data reveals four runaway planets that are reminiscent of Earth.
The most unique interloper into our Solar System has a natural explanation that fits perfectly — no aliens required.
From the Big Bang to dark energy, knowledge of the cosmos has sped up in the past century — but big questions linger.
At four million solar masses, the Milky Way’s supermassive black hole is quite small for a galaxy its size. Did we lose the original?
Astronomers find a third type of supernova and explain a mystery from 1054 AD.
A Carrington-magnitude event would kill millions, and cause trillions of dollars in damage. Sadly, it isn’t even the worst-case scenario.
Do we still remember what we learned in the 1940s?
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 […]
Astronomers possibly solve the mystery of how the enormous Oort cloud, with over 100 billion comet-like objects, was formed.
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 […]
Look out at a distant object, and you’re not seeing it as it is today. It’s size, brightness, and actual distance are all different.
The far side of the Moon is incredibly different from the Earth-facing side. 63 years later, we know why the Moon’s faces are not alike.
Physicists have yet to pinpoint the hypothetical matter that keeps galaxies from flying apart. Now they have a new focus.
