On Tuesday, SpaceX ran its second test of Starhopper, the prototype
for their enormous future passenger spacecraft. The static fire test was meant
to measure the Raptor engines that power the craft. But at the end of the five
second test, Starhopper was instead surrounded by an enormous fireball, as
shown in a video from the rural Texas test site gathered by Everyday Astro ...read more
Gravitational waves can be detected from the collision of massive objects in the universe, but also from much smaller objects like dark matter particles. (Credit: EPA/R. Hurt / Caltech-JPL)
In 2015, scientists made history by detecting the first gravitational waves — ripples in space-time predicted by Albert Einstein a century earlier. The waves were created by the merger of two black holes, each one much larger than the sun. And since then, the Laser Interferometer Gravitational-Wave O ...read more

Earthquakes used to be uncommon in Middle America. But in the last decade, quakes numbers have skyrocketed in Oklahoma and Kansas. The major uptick in seismic activity has risen alongside the growth of oil and gas production in the area. When fossil fuel companies dispose of wastewater by injecting it into underground wells, the increased pressur ...read more

It’s easy, amid the celebrations of the 50th anniversary of the Apollo 11 moon landing, to see it as an inevitable success. NASA had been preparing for the task for years, ever since President John F. Kennedy made his famous speech at Rice University in 1962, declaring America would “go to the moon in this decade.” Whe ...read more

If you cooked dinner today — even a Cup O Noodles — you did something extraordinary and uniquely human. While the rest of the animal kingdom subsists on raw food, we Homo sapiens cook our chow.
And according to some researchers, this distinction made all the difference: When our ancestors mastered cooking roughly 2 million years ago it changed the course of human evolution, they say. Because cooked food provides more energy, the habit led to s ...read more

He’s pioneered several multi-billion dollar companies, launched one of his cars into space, and now Elon Musk wants to hack your brain.
On Tuesday night, the CEO and co-founder of Tesla and SpaceX lifted the veil of secrecy on a new venture, called Neuralink. The company launched in 2016 promising to create cutting-edge brain-machin ...read more
Corals stressed by heat and other environmental conditions can bleach, or kick out their life-giving algae companions. (Credit: sabangvideo/Shutterstock)
It’s been said time and time again that climate change is killing coral reefs. Rising ocean temperatures cause bleaching, which damages huge chunks of coral ecosystems from Australia to the southern United States.
But heat isn’t the only reason reefs are dying. Nitrogen runoff from human activities could be damaging corals ar ...read more
