Any uncertainty in the calculation of the object’s orbit causes variations in the predicted solution. Instead of one precise orbit, the calculation usually gives scientists a cloud of its possible orbits. The ellipse enclosing these locations is called an error ellipse.

This incredible image, featuring flashing Starlink satellites and Earth's glowing atmosphere, was captured over the Pacific Ocean by NASA astronaut Don Pettit

"It could represent some of the oldest and most pristine water ever observed, formed in another planetary system and preserved throughout its interstellar journey."

Throughout history, people have viewed seasons as relatively stable, recurrent blocks of time that neatly align farming, cultural celebrations and routines with nature's cycles. But the seasons as we know them are changing.

Astronomers have likely witnessed a planet forming in real time, seen inside a spiral arm of the HD 135344B protoplanetary disc—exactly where theory predicted. The direct light detection is what sets this apart from previous hints of forming worlds.

NISAR, a joint mission of NASA and ISRO set to launch on July 30, will be able to see shifts in the landscape smaller than a centimeter to give warning of potential natural disasters.

In the 1950s, Stanley Miller and Nobel laureate Harold Urey conducted experiments at the University of Chicago in which they simulated the conditions of primordial Earth—an atmosphere of methane, ammonia, hydrogen, and water with electric arcs of lightning—and produced amino acids, the organic molecules that form the building blocks of proteins.
