The Hubble Space Telescope treats astronomers to gorgeous close-up views of the eerie outer planets. But it's a bit of a trick when it seems like the planet's looking back at you! In this view, the shadow of the Jovian moon Ganymede swept across the center of the Great Red Spot—a giant storm on the planet. This gave Jupiter the uncanny appearance of having a pupil in the center of a 10,000-mile-diameter "eye." Now if it blinks, we may really have to worry!
Hubble treats astronomers to gorgeous close-up views of the eerie outer planets. But it's a bit of a trick when it seems like the planet's looking back at you! This happened on April 21, 2014, when Hubble was being used to monitor changes in Jupiter's immense Great Red Spot (GRS) storm. During the exposures, the shadow of the Jovian moon Ganymede swept across the center of the GRS.
This gave the giant planet the uncanny appearance of having a pupil in the center of a 10,000-mile-diameter "eye." Momentarily, Jupiter took on the appearance of a Cyclops planet! The shadows from Jupiter's four major satellites routinely cross the face of Jupiter.
This natural-color picture was taken with Hubble's Wide Field Camera 3.

FAQs
3. Given this spacing, why do you think little, rocky Venus can outshine giant Jupiter in the night sky? Both are covered with highly reflective clouds, and although it is much smaller, Venus is also much, much closer.
What is the eye of Jupiter? ›
The Eye of Jupiter is a mysterious artifact that both humans and Cylons believe holds the key to finding Earth, the last hope for humanity's survival. Contrary to expectations, the Eye is not hidden in the Temple of Five, but within the dying star of the algae planet.
Which planet has the big eye? ›
This gave the giant planet the uncanny appearance of having a pupil in the center of a 10,000 mile-diameter “eye.” For a moment, Jupiter “stared” back at Hubble like a one-eyed giant Cyclops. Click on the image to view Jupiter from a distance.
How big is Jupiter's eye? ›
Jupiter's Great Red Spot rotates counterclockwise, with a period of about 4.5 Earth days, or 11 Jovian days, as of 2008. Measuring 16,350 km (10,160 mi) in width as of 3 April 2017, the Great Red Spot is 1.3 times the diameter of Earth.
What is the best explanation for why the outer planets are gas giants and not rocky planets? ›
The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose. In the inner solar system temperatures were as high as 2000 K, while in the outer solar system it was as cool as 50 K.
What other objects in the night sky are brighter than Jupiter? ›
Brightest Objects in the Night Sky to Observe: The Moon (seriously bright!) Venus (magnitude -4.3) Jupiter (magnitude -2.2)
Can humans see Jupiter? ›
Jupiter appears as a bright, white disk to the naked eye. The planet's surface is covered in bands of clouds, which can be seen under very dark skies. Jupiter's Great Red Spot, a massive storm that has been raging for centuries, is also visible under very dark skies.
What is the largest storm in the universe? ›
The Red Spot is the largest known storm in the Solar System. With a diameter of 15,400 miles, it is almost twice the size of the entire Earth and one-sixth the diameter of Jupiter itself. The long lifetime of the Red Spot may be due to the fact that Jupiter is mainly a gaseous planet.
How long will Jupiter's red spot last? ›
It's likely Jupiter's Great Red Spot has waxed and waned and come and gone over Millenia and may be one of many. It's as likely there may be more than one in 100 years than none. The great red spot is a giant storm. It has changed in the past and will change in the future.
What is Earth's twin planet? ›
Venus and Earth are sometimes called twins because they're pretty much about the same size. Venus is almost as big as Earth. They also formed in the same inner part of the solar system.
On Jupiter, storms can last a very long time because there is no land and weather is driven largely by the consistent internal heat of the planet. This is different from Earth's weather, which is fueled by solar energy heating the Earth. However, Jupiter's weather is always changing.
What is the red dot in my eye? ›
A subconjunctival hemorrhage (sub-con-JUNK-tih-vul HEM-er-ij) is a red spot on the white of the eye. It can look scary, but it's usually harmless, doesn't hurt, and won't affect vision. Most subconjunctival hemorrhages go away without treatment in a few days or weeks.
What god is Jupiter? ›
Jupiter was the Roman god of the sky and of thunder. As the chief Roman god, he was the king of a pantheon of dozens of deities, including Neptune, Mars, and Venus. The deity Jupiter was closely connected to the Greek deity Zeus.
Who is the son of Jupiter? ›
Juno bore Jupiter four children: Vulcan, the disfigured blacksmith god; Mars, the god of war; Juventas, the cup-bearer to the gods and goddess of youth; and Lucina, the goddess of childbirth.
Is Jupiter the son of Saturn? ›
Roman God Jupiter was the son of Saturn, the god of agriculture, and Ops, the goddess of wealth and abundance. He had five other siblings who were Neptune (god of the sea), Pluto (ruler of the underworld), Vesta (goddess of the hearth), Juno (goddess of fertility) and Ceres (goddess of agriculture).
Why do you think that Venus looks brighter in the sky than Jupiter? ›
Venus is so bright because its thick clouds reflect most of the sunlight that reaches it (about 70%) back into space, and because it is the closest planet to Earth.
Why is Jupiter so bright in the night sky? ›
By contrast, Jupiter is extraordinarily reflective because it is covered with clouds. Suspended crystals of methane and ammonia reflect the sun's light very efficiently, giving Jupiter has a respectable albedo of . 51. Just over half of the light it receives from the sun bounces back into space.
Why are Venus and Jupiter so visible? ›
Because Venus is closer to the Sun, it's always going to be apparently close to the Sun and if you can see it, it'll be just after sunset or just before sunrise. But as Jupiter's orbit is outside ours, it can be in any direction compared to the Sun.
How do you identify Venus and Jupiter in the night sky? ›
If you have a telescope, Jupiter is easily distinguished by its moons and its bands. Whereas Venus often has a clear crescent or gibbous shape, And, of course Venus is actually considerably brighter than Jupiter, so if they are side-by-side there would be no doubt which is which.
