📆🌙 We often take the seven-day week for granted, but its origins are rooted in the ancient world's observations of the sky.

From the Babylonians tracking the phases of the #moon to the Romans naming days after the visible #planets, this historical look explains why the seven-day cycle stuck – even when revolutionaries tried to change it.

Hello all 🫠
On last March 3, the alignment of the #planets caused the #Earth to #eclipse its natural satellite, the #Moon . The next day, driven by a strong #Autan wind, a thick cloud of #dust from the Sahara Desert partially eclipsed our #Sun , dimming its usual brightness. This was followed by this surreal #sunset ...

Scientists find evidence of faraway worlds colliding
Astronomers say unusual readings from a star system 11,000 light-years away suggest that two of the planets circling the star crashed into each other, creating a huge, light-obscuring cloud of rocks and dust.

The analysis, laid out this week in a paper published

Fast Stars and Rogue #Planets in the Orion #Nebula

Below Orion's belt lies the Great Nebula of Orion, home to the bright Trapezium star cluster. This active star-forming region contains fast-moving rogue planets and stars, revealed by comparing Hubble images over years. The red hues of many stars are due to dust scattering their blue light.

Sky Glows over Paranal Observatory

Telescopes use lasers to create artificial stars, aiding in correcting atmospheric distortions for clearer astronomical observations. Adaptive optics techniques enable high-resolution imaging from the ground. The image shows Paranal Observatory's telescopes under a sky with airglow and the Milky Way.

Scientists tracked faint signals from the stars — and may have turned up hundreds of undiscovered planets

A new study shows that stars with low magnetic activity are likely to support exoplanetary systems, making the hunt for these celestial obje...

Alright, I should probably do more work on this old thing, but I actually quite like the concept. Travel times to and from Saturn using constant acceleration...of one Earth gravity! Quite achievable with nuclear pulse propulsion...
