Astronomy
The ESA's Gaia mission just broke the record for closest black hole by over 1,000 light-years. Is there an even closer one out there?
Science is for everyone, even those possessing strongly held beliefs that seem to conflict with the best available evidence.
IceCube just found an active galaxy in the nearby Universe, 47 million light-years away, through its neutrino emissions: a cosmic first.
We know the Universe is expanding, but scientists don't agree on the rate. This is a legitimate problem.
The largest hazardous asteroid found in the last 8 years showcases a little-known class of planet-killers. And we're woefully unprepared.
In 1995, Hubble peered at the Pillars of Creation, forever changing our view. Now in 2022, JWST completes the star-forming puzzle.
The stars circle each other every 51 minutes, confirming a decades-old prediction.
Most exoplanets have been found around single stars via the transit method. But binary star systems might contain even more of them.
Early relics and late-time objects give incompatible results for the expanding Universe. This independent anomaly intensifies the problem.
The DART mission tested whether it's possible to deflect an asteroid by crashing something into it.
The Universe gravitates so that normal matter and General Relativity alone can't explain it. Here's why dark matter beats modified gravity.
1.9 billion years ago, a star's explosive death created a black hole. Its light just arrived at Earth. But did it set a cosmic record?
NASA is creating a planet habitability index, and Earth may not be at the top. With our current data, ranking habitability is guesswork.
Over the past 50 years, 27 leap seconds have been added to our time.
With its first view of a protoplanetary disk around a newly forming star, the JWST reveals how alone individual stellar systems truly are.
The Universe begins with negligible amounts of angular momentum, which is always conserved. So why do planets, stars, and galaxies all spin?
Venerated astrophysicist Carl Sagan entertained the possibility.
Before we discovered gravitational waves, multi-messenger astronomy got its start with light and particles arriving from the same event.
It's the very closest stars to us that hold the key to unlocking the possibilities for life in star systems all throughout the Universe.
This technological feat changes our cosmic history.
Sooner or later, Earth is going to be hit by a large enough space object to cause significant damage to humanity. Stopping them isn't easy.
The James Webb Space Telescope viewed Neptune, our Solar System's final planet, for the first time. Here's what we saw, and what it means.
UAP are no laughing matter anymore.
Recent research suggests that Earth’s magnetic field bounced back just as complex life was starting to emerge on our planet.
Yes, NASA's Perseverance rover found organics on Mars. So did Curiosity. Unfortunately, that doesn't mean anything in the search for life.
"Spanish Stonehenge" contains 526 giant stones, three circular burial sites, a quarry, and four necropolises.
“The more we understand ourselves and the universe, the more magnificent it is.”
