Find out the truth for yourself. If this past year has shown us anything, it’s how thoroughly we rely on high-quality expertise. As the COVID-19 pandemic swept the globe, it […]
Ari Loeb, who suggested in 2018 that the mysterious object was an alien craft, is back to discuss the evidence.
In 2006, Pluto was demoted in a very controversial decision. Unless you ignore nearly all of planetary science, it’ll never be one again.
If there are human-sized creatures walking around on other planets, would we be able to view them directly?
Some scientists believe the lightning-produced frequencies may be connected to our brain waves, meditation, and hypnosis.
Scientists have long puzzled over how Mars, a cold and dry planet, was once warm enough to support liquid water.
About 359 million years ago, at the end of the last phase of the Devonian period, there was a mass extinction event or series of events. An estimated 70 to […]
“The Expanse” is the best vision I’ve ever seen of a space-faring future that may be just a few generations away.
The Younger Dryas impact hypothesis argues that a comet strike caused major changes to climate and human cultures on Earth about 13,000 years ago.
While Mars is known as a frozen, red planet today, it has all the evidence we could ask for of a watery past, lasting for approximately the first 1.5 billion […]
MIT engineers devise a decision map to identify the best mission type to deflect an incoming asteroid.
You think you’ve had a day where everything that went wrong could? T. rex has you beat.
Radar astronomy is nothing new, but a new transmitter may give us unprecedented image resolution.
‘Fast Optical Bursts’ will confound ground-based astronomy. As of 2021, planet Earth is currently experiencing the least pristine night sky in recorded history. Prior to the development of artificial lighting, […]
A meteorite that smashed into a frozen lake in Michigan may explain the origins of life on Earth, finds study.
Creating an afterlife—or a simulation of one—would take vast amounts of energy. Some scientists think the best way to capture that energy is by building megastructures around stars.
The meteorites suggest astronomers may have small, early planets wrong.
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 […]
The night sky is already noticeably different, and bigger changes are ahead. For all of human history until the launch of Sputnik, the only objects in the night sky were naturally […]
Inventions with revolutionary potential made by a mysterious aerospace engineer for the U.S. Navy come to light.
If you want to understand what the Universe is, how it began, evolved, and will eventually end, astrophysics is the only way to go.
And could Earth-based life provide the seeds for biology elsewhere? Today, on Earth, there’s an enormous variety and diversity of life on our planet. Every single surviving lifeform appears, in […]
Is the Universe finite or infinite? Does it go on forever or loop back on itself? Here’s what would happen if you traveled forever.
With launch, deployment, calibration, and science operations about to commence, here are 10 facts that are absolutely true.
No matter how controversial or politicized our world becomes, science remains humanity’s best tool for figuring out how things work.
Discussions of human evolution are usually backward looking, as if the greatest triumphs and challenges were in the distant past.
Participation in community science programs has skyrocketed during COVID-19 lockdowns.
Even with leap years and long-term planning, our calendar won’t be good forever. Here’s why, and how to fix it.
A 71% wet Mars would have two major land masses and one giant ‘Medimartian Sea.’
