The New Horizons spacecraft snapped the first-ever photo of Pluto on Wednesday, Jan. 21. The image, which was taken from a distance of about 4.9 million miles (7.8 million kilometers), shows the dwarf planet and its largest moon, Charon, as tiny specks against a backdrop of stars.
“This is the most distant object that we’ve ever photographed,” said Hal Weaver, New Horizons project scientist at the Johns Hopkins University Applied Physics Laboratory (APL), in a statement. “And it’s the first time we’ve seen Charon as a separate object.”
The photo was taken as part of a series of test images that New Horizons snapped on its way to Pluto. The spacecraft is scheduled to reach the dwarf planet on July 14, 2015, making it the first probe ever to visit the distant world.
“It will be thrilling to see the close-up views of Pluto and Charon that we have planned for the next few months,” Weaver said.
Pluto was discovered in 1930 by American astronomer Clyde Tombaugh. The dwarf planet is about 1,453 miles (2,334 kilometers) wide and has a mass about one-sixth that of Earth. It is the most distant member of the solar system, orbiting about 39 times farther from the sun than Earth does.
Charon is about half the size of Pluto and has a mass about one-eighth that of Earth. The two objects are in a 1:1 orbital resonance, meaning that they complete one orbit around the sun together for every two orbits made by Pluto.
In 2006, the International Astronomical Union (IAU) reclassified Pluto as a “dwarf planet” due to its small size and lack of a spherical shape.

Who took the first picture of Pluto?
Who took the first picture of Pluto?
The first image of Pluto was taken on March 13, 1978, by the United States Naval Observatory’s (USNO) 1.55-meter telescope located in Flagstaff, Arizona. The image was taken as part of a series of images to search for a potential 10th planet in the Solar System. The telescope’s operator, Robert Harrington, was the first person to spot Pluto in the images.
Can I take a picture of Pluto?
Yes, you can take a picture of Pluto. While it is no longer classified as a planet, it is still an interesting and photogenic object in the night sky.
Pluto is located in the outermost reaches of the solar system, and is only visible to the naked eye under the best conditions. However, it can also be photographed with a digital camera or telescope.
To capture an image of Pluto, you’ll need to know its coordinates. You can find these online, or in a star chart. Once you have the coordinates, you can use them to aim your telescope or camera.
Be sure to adjust your exposure settings accordingly, as Pluto is a very faint object. You may need to use a longer exposure time, or a higher ISO setting.
With a little patience and some basic equipment, you can add Pluto to your astrophotography portfolio!
When was Pluto discovered?
When was Pluto discovered?
Pluto, the ninth and outermost planet in the solar system, was discovered on February 18, 1930, by American astronomer Clyde Tombaugh.
Tombaugh was working at the Lowell Observatory in Flagstaff, Arizona, when he found an anomaly in the motion of the planets across the night sky. After studying thousands of photographic plates of the sky, he identified an object that was moving in a way that could not be explained by the other planets.
After confirming that the object was indeed a new planet, Tombaugh named it Pluto, after the Roman god of the Underworld.
When was Jupiter first photographed?
There is no definitive answer to the question of when Jupiter was first photographed. However, there are several contenders for the title.
One of the earliest photos of Jupiter may have been taken by Giovanni Cassini in 1690. However, this is not certain, as the photo is not well-preserved.
The first confirmed photograph of Jupiter was taken by William Lassell in 1851. This photo was taken with a 24-inch reflecting telescope.
In 1858, the first photo of Jupiter was taken that showed the planet’s disk. This photo was taken by Francis Leavenworth.
Jupiter was first photographed from a spacecraft in 1979, when the Voyager 1 probe took a photo of the planet from a distance of roughly 5.5 million kilometers.
When was the first photo taken?
The first photo was taken in 1826 by Joseph Nicéphore Niépce.
Can humans live on Pluto?
Pluto, once considered the ninth and most distant planet from the sun, is now classified as a dwarf planet. With a diameter of 1,473 miles, it is about two-thirds the size of Earth’s moon. Although it is much smaller than Earth, scientists are still exploring the possibility of human habitation on Pluto.
The surface temperature of Pluto ranges from about -380 degrees Fahrenheit to -230 degrees Fahrenheit, so it is not hospitable to humans as it is currently. However, with the development of new technology, it may be possible for humans to live on Pluto in the future.
Pluto has an atmosphere, which is made up of nitrogen, methane, and carbon monoxide. These gases could be used to create a type of greenhouse effect that would warm the planet enough for humans to live there.
Additionally, Pluto has a water ice surface, which could be used to produce water and oxygen for human habitation.
There are still many challenges to overcome before humans can live on Pluto, but the possibility is being explored and development is ongoing. With the continued exploration of our solar system, it is possible that humans may one day be able to call Pluto home.
When was Pluto last seen?
Since its discovery in 1930, Pluto has been a source of fascination for astronomers. But when was Pluto last seen by humans?
Pluto was last seen by humans on February 11, 1990. It was photographed from the Hubble Space Telescope.
Since then, Pluto has only been seen from Earth indirectly, as it is too faint to be seen with the naked eye.
Pluto was demoted to a “dwarf planet” in 2006, after it was discovered that it does not meet the criteria for a full planet.
Nevertheless, it remains an interesting object for astronomers to study. In 2015, the New Horizons spacecraft made a historic flyby of Pluto, providing more information about this distant world.
