This is the view of the heavens people had for millennia. Pre-modern societies watched the sky and created cosmographies, maps of the skies that provided information for calendars and agricultural cycles. They also created cosmologies, which, in the original use of the word, were religious beliefs to explain the universe. The gods and the heavens were inseparable.

The White House announced Tuesday it is directing NASA to create a unified time standard for the Moon and other celestial bodies, as governments and private companies increasingly compete in space.

With the United States keen to set international norms beyond Earth's orbit, the White House Office of Science and Technology Policy (OSTP) instructed the US space agency to formulate a plan by the end of 2026 for a standard it is calling Coordinated Lunar Time.

A cosmic ‘speed camera’ just revealed the staggering speed of neutron star jets

Energetic cosmic beams known as jets are seen throughout our universe. They are launched when material – mainly dust and gas – falls in towards any dense central object, such as a neutron star (an extremely dense remnant of a once-massive star) or a black hole.

The jets carry away some of the gravitational energy released by the infalling gas, recycling it back into the surroundings on far larger scales.
