What was the biggest planet ever discovered?

# data[].attributes.body
The largest planet every discovered is called ROXs 42Bb, a planet with 2.5 times the radius of Jupiter. This exoplanet was directly imaged and discovered in 2013. Unlike many of the other largest exoplanets, this one is believed to be a planet and not a brown dwarf, an object between a planet and a star.

when are we going to go back to the moon?

# data[].attributes.body
NASA plans to launch an uncrewed spacecraft, part of the Artemis I mission, as soon as this weekend to orbit the moon and then return to Earth after about a month and a half. If everything goes as planned, a future mission could land astronauts on the moon in 2025

# data[].attributes.body
NASA aims to launch astronauts to Mars by the late 2030s or early 2040s. Making that vision a reality will be challenging. Assuming the funding and technology come into play at the right time, for example, the round-trip travel time would still be about 500 days given the distance between Earth and Mars

The first way they used was by looking at the oldest stars because their light has been traveling towards our earth ever since they were born because we can find out the stars’ age and theoretically predict the age of the universe. (Written in my own words and my own mind)

Einstein’s theory predicts that the closer you move toward the source of this gravitational pull, the slow time will become. If you could stand at the edge of the supermassive black hole in the center of our galaxy, then more than 700 YEARS would pass by in a single minute (let’s just say that is fascination to know).
