‘Infernal galactic world’ of old, exploding stars lurks beneath the surface of the Milky Way.

During the Milky Way’s roughly 13.6 billion year history, billions of stars formed, grew, and eventually died in spectacular supernova explosions. So, where do all their bodies hide? In a new research published on August 25 in Monthly Notices of the Royal Astronomical SocietyNow, astronomers set out to dig up those long-lost stellar bodies (so …

‘Pale blue dot’ planets like Earth may make up only 1% of potentially habitable worlds

Earth-like worlds with Earth-to-ocean ratios similar to our planet may be extremely rare. According to a new study, Earth-like planets that cover about 30% of the Earth’s surface may make up only 1% of the Earth’s surface. rocky worlds In stellar habitable zones, the regions around stars where liquid water can exist on the surface …

Has the mystery of how the moon formed finally been solved?

It’s a question that has puzzled scientists for hundreds of years – how exactly was our moon formed? Since the 1970s, astronomers have suspected that the moon arose when a giant protoplanet called Theia struck Earth. However, the nature of this collision and what happened immediately after it have been a matter of debate. Some …

The Pacific Ocean is set to disappear as the Earth’s continents merge into a new supercontinent

The Pacific’s days are numbered, according to a new giant computer simulation of Earth’s permanently drifting tectonic plates. The good news? The oldest ocean on our planet still has another 300 million years to go. If the Pacific Ocean is lucky, it may celebrate its billionth birthday before it finally comes out of existence. But …

Massive trail of debris from the collision of DART with the asteroid Demorphos captured by the SOAR telescope

Astronomers using the SOAR telescope in Chile captured a massive plume of dust and debris emanating from the surface of the asteroid Demorphos by NASA’s DART spacecraft when it collided on Sept. The pressure of the sun’s radiation pushed it away, not unlike the comet’s tail – it extends from the center to the right …
