How big is the Great Dark Spot?

How big is the Great Dark Spot?

The Great Dark Spot was captured by NASA’s Voyager 2 space probe in Neptune’s southern hemisphere. The dark, elliptically-shaped spot (with initial dimensions of 13,000 × 6,600 km, or 8,100 × 4,100 mi) of GDS-89 was about the same size as Earth, and was similar in general appearance to Jupiter’s Great Red Spot.

How big is Neptune’s Great Dark Spot?

The feature is roughly 4,600 miles across. The estimated width of the smaller spot is 3,900 miles. The large storm is the fourth transient dark spot Hubble has observed since 1993. NASA’s Voyager 2 spacecraft first imaged two dark features in Neptune’s southern hemisphere in 1989 as Voyager flew by the distant planet.

How large is the Great Red Spot?

At 10,000 miles across, the Great Red Spot is the largest storm in our solar system and has been continually observed for around 200 years, but it’s been around for much longer. (Compare that with big storms on Earth, which generally last a few days or weeks at most.)

What is the greatest dark spot?

The Great Dark Spot was a huge spinning storm in the southern atmosphere of Neptune which was about the size of the entire Earth. Winds in this storm were measured at speeds of up to 1,500 miles per hour. These were the strongest winds ever recorded on any planet in the solar system!

How big is Jupiter’s black hole?

It covers a region about 14.6 million miles in diameter. That’s roughly 168 Jupiters across, and inside is the same amount of mass as 4 million suns combined. Now that may sound big, but Sagittarius A* is small compared to other supermassive black holes.

Does Neptune rain diamonds?

A new study has found that “diamond rain” may be more common on ice giant planets like Neptune and Uranus than previously thought. For the first time, scientists were able to observe diamond rain as it formed with their experiment designed to mimic the extreme temperatures and pressure found on those planets.

What planet is blue?

Neptune: The Blue Planet | NASA.

Is Neptune 17 times bigger than Earth?

Neptune is the eighth planet from the sun in our solar system. This blue gas giant is far larger than Earth, at more than 17 times Earth’s mass and nearly 58 times Earth’s volume, according to NASA (opens in new tab).

Can you walk on Neptune rings?

But temperatures at this region would be thousands of degrees; hot enough to melt rock. And the pressure from the weight of all the atmosphere would be crushing. In short, there is simply no way one could stand on the “surface of Neptune”, let alone walk around on it.

How big is Jupiter’s eye?

Measuring 16,350 km (10,160 mi) in width as of 3 April 2017, Jupiter’s Great Red Spot is 1.3 times the diameter of Earth. The cloud-tops of this storm are about 8 km (5.0 mi) above the surrounding cloud-tops.

Is Jupiter’s storm getting bigger?

Full Article. Jupiter’s trademark Great Red Spot – a swirling anticyclonic storm feature larger than Earth – has shrunken to the smallest size ever measured. Astronomers have followed this downsizing since the 1930s.

Can Earth fit in the Great Red Spot?

We’ve long known just how great the Great Red Spot is. The storm’s diameter is about 10,000 miles, or more than 16,000 kilometers, wide, meaning that our planet Earth could fit completely inside the wild tempest.

Does the Great Dark Spot move?

The Great Dark Spot of Neptune can move! For instance, in 1989, when Voyager 2 spacecraft passed Neptune, it observed two storms. The more prominent spot moved to the south first and then changed its direction to the north.

Is The Great Red Spot bigger than the Great Dark Spot?

March 12, 2003: For more than a century astronomers thought that the Great Red Spot was the biggest thing on Jupiter. Not anymore. Images from NASA’s Cassini spacecraft have revealed something at least as large. The Great Dark Spot.

Will the Great Red Spot ever disappear?

One of the solar system’s most iconic landmarks is about to vanish. Jupiter’s Great Red Spot, a gigantic storm more than twice the size of the Earth, has persisted for centuries. But now scientists predict it could disappear forever in as little as 20 years.

What is the biggest hole in the universe?

The largest black hole ever found in the known universe is found in Ton 618. This is a hyper luminous Lyman-alpha blob that has a black hole that measures 6.6×1010 solar masses. It has a mass that equals about 66 billion times that of the Sun. This supermassive black hole is some 18.2 billion light-years from Earth.

Is black hole is bigger than Sun?

Peppered throughout the Universe, these “stellar mass” black holes are generally 10 to 24 times as massive as the Sun.

Can a planet fit in a black hole?

The only way Earth could be swallowed by a black hole would be if our planet happened to stray across a wandering black hole’s event horizon. That’s something that is not going to happen any time soon, and likely never will.

How big are the dark spots on the moon?

Scientists analyzed Oceanus Procellarum, or the Ocean of Storms, a dark spot on the near side of the moon more than 1,800 miles (3,000 kilometers) wide.

Does the Great Dark Spot move?

The Great Dark Spot of Neptune can move! For instance, in 1989, when Voyager 2 spacecraft passed Neptune, it observed two storms. The more prominent spot moved to the south first and then changed its direction to the north.

How large is the great white spot?

The head of one of these storms—popularly called “great white spots,” in analogy to the Great Red Spot of Jupiter—can be as large as Earth.

Is Neptune’s Great Dark Spot still there?

The Hubble Space Telescope identified a storm in 2018, a dark spot some 4,600 miles across. Since that time, it appears to have drifted toward the equator but then swooped back up north, according to the latest Hubble observations.
