The James Webb Space Telescope (JWST) will study many dangerous cosmic phenomena, knowledge of which may help save humanity.
Even with all the recent impacts we’ve seen, it might be more “foe” than “friend” to us.
And the one step we can take to show extraterrestrials we’re figuring it out. Every year, Earth’s meteor showers accomplish two important tasks. This composite photograph shows a large number of […]
Isaac Newton and Albert Einstein are locked in an eternal battle over the nature of gravity. Whose side are you on?
Forensics has reached the final frontier, and could be used to solve future space accidents—or crimes.
“The surface is no longer a record of every impact the moon has ever had, because at some point, impacts were erasing previous impacts.”
In many ways, we are still novices playing with toy models seeking to understand the stars.
“Should they strike, each of them has an energy at impact equal to all of the nuclear weapons on Earth combined.”
Planets can be Earth-like or Neptune-like, but only rarely are in between. This hot, Saturn-like planet hints at a solution to this puzzle.
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.
New studies find the interstellar comet 2I/Borisov is the most “pristine” ever discovered.
If a large asteroid strikes Earth, it has the potential to release an enormous amount of energy, leading to local or even global catastrophes. The strike that led to the […]
Einstein’s theory of general relativity introduced the concept of space having a shape. So, what is the shape of space?
Hint: They hold off on talking about their alien god until much later.
The classic picture of Jupiter’s great rocky core might be entirely wrong.
60% of all potentially dangerous asteroids remain undetected.
Over 50 years since humans last walked on the Moon, astronaut footprints and rover tracks are still visible. But they won’t last forever.
Astronomers possibly solve the mystery of how the enormous Oort cloud, with over 100 billion comet-like objects, was formed.
Climate and ecological changes, as well as disruptions to the food chain, were already killing off the dinosaurs.
Most people have a distorted view of what being a scientist is like. Scientists need to make a greater effort to challenge stereotypes.
In all of science, no figures have changed the world more than Einstein and Newton. Will anyone ever be as revolutionary again?
“Even with my training, I still got insights from the book’s descriptions. That’s how good Carroll is at explaining physics.”
Finding alien technology on the seafloor would be truly incredible. This extraordinary claim, however, is debunked by the actual evidence.
Only 17 years after its discovery have we learned we’re safe from asteroid Apophis. Ever since its 2004 discovery, asteroid 99942 Apophis has threatened planet Earth. Asteroid Apophis has been measured […]
We may have discovered alien life already but rejected the evidence too quickly because it seemed false at first glance.
Astronomy’s roots rest in the very origins of humanity. We have always looked to the skies for answers. We are starting to get them.
“If we find just one other example of biology out there, then life is not an accident.”
