A Baby Planet May Have Once Smashed Into Jupiter - SciShow News

The video discusses Jupiter's significant impact on its surroundings and the Juno spacecraft's mission to study its interior. Juno's data revealed unexpected findings about Jupiter's core, suggesting a past collision with a massive object. Simulations support this hypothesis, but alternative explanations are also considered. The video also explores the search for Earth-like exoplanets, highlighting the challenges in estimating their abundance due to data biases. Researchers use innovative methods to overcome these biases, suggesting a significant number of Earth-like planets in the galaxy.

What has the Juno spacecraft been primarily studying since 2016?

• Jupiter's magnetic field

• Jupiter's atmosphere

• Jupiter's moons

• Jupiter's gravitational field

What hypothesis is proposed to explain the fuzzy boundary of Jupiter's core?

• Jupiter's core is eroding

• Jupiter was struck by a massive object

• Jupiter's core is made of gas

• Jupiter's core is expanding

What is one challenge in estimating the number of Earth-like exoplanets?

• Lack of advanced telescopes

• Biases in data from the Kepler mission

• Too many stars to study

• Exoplanets are too far away

What did the team use to estimate the number of Earth-like planets?

• Data from the Juno spacecraft

• Data from the Hubble Space Telescope

• Data from the Voyager mission

• Data from the Kepler mission

What is the estimated ratio of Earth-like planets to sun-like stars according to the new study?

• One Earth-like planet per 10 sun-like stars

• One Earth-like planet per 4 sun-like stars

• One Earth-like planet per 20 sun-like stars

• One Earth-like planet per 2 sun-like stars

What is a major source of uncertainty in estimating Earth-like planets?

• The brightness of stars

• The parameters used in data analysis

• The size of planets

• The distance of stars

Why is it difficult to confirm the presence of Earth-like exoplanets?

• They are too far from their stars

• They are often hidden by other celestial bodies

• They orbit their stars too closely

• They are too small to detect
