'Monster' Quake on Mars Is The Biggest Ever Recorded on Another Planet, NASA Says

‘Monster’ Quake on Mars Is The Biggest Ever Recorded on Another Planet, NASA Says

In terms of seismic events on the red planet (or indeed any other planet besides Earth), this is the biggest one recorded so far: the NASA InSight lander has recorded a ‘monster’ of a marsquake, which is estimated to have hit magnitude 5 on the scale used on Earth. That beats the previous record holder, …

Humans are causing the ocean to lose its memory, study shows: "It's almost as if the ocean is developing amnesia"

Humans are causing the ocean to lose its memory, study shows: “It’s almost as if the ocean is developing amnesia”

Earth’s oceans are feeling the wrath of human-induced climate change. Glaciers are melting, sea levels are rising and reefs are dying – and now, according to a new study published in Science Advances, the sea is losing its memory altogether. Unlike weather, which can change wildly and rapidly day-to-day, Earth’s oceans usually only have slight …

Astronomers see a big boom when a black hole's magnetic field suddenly flips over

Astronomers see a big boom when a black hole’s magnetic field suddenly flips over

Two hundred thirty-six million light-years away, and hence 236 million years ago, a strange and intense light erupted from a distant astronomical object. The intergalactic rumble was detected here on Earth, where astronomers rapidly ascertained that the flare originated around a supermassive black hole. A spontaneous reversal of the black hole’s magnetic poles could be …
