Hubble’s observations captured springtime on Neptune for the first time, tracking waves of massive storms - each one larger than the distance from Kansas to New York – with temperatures colder than -350✯ (210✬). Neptunian winds blow at an average of 900 miles per hour (1,450 km/h), and huge storms - some the size of Earth itself - come and go with regularity. On Neptune, Hubble has captured the most insightful images to date of a planet whose blustery weather bewilders scientists. For instance, Hubble has observed the downsizing of Jupiter’s most famous feature, the spinning, cyclone-like storm known as the Great Red Spot. In the outer solar system, turbulent storms dot the atmospheres of the giant planets - Jupiter, Saturn, Uranus, and Neptune - allowing Hubble to become an expert storm tracker. Hubble’s Earth-orbit perspective allowed it to view the entirety of the global storm, while its long-term presence in space continues to allow it to monitor changes in Mars’s seasons over months and years. In 2018, a spring dust storm erupted in the southern hemisphere and ballooned into a global event enshrouding the entire planet. Hubble’s ability to see ultraviolet, infrared, and visible light makes it the ideal meteorologist for the solar system, allowing it to probe below the cloud tops and investigate the massive storms on distant planets.Īmong these constantly shifting weather patterns are dust storms on Mars. The short-term phenomena Hubble has witnessed on other planets includes the weather - watching storms arise and dissipate across the faces of other worlds. ![]() But since its launch in 1990, the Hubble Space Telescope has kept a watchful eye on events within our own solar system, which happen on the timescale of days, weeks, and years. ![]() Many astronomical phenomena occur over millions of years. What has Hubble taught us about storms in the solar system? Four Successful Women Behind the Hubble Space Telescope's Achievements.Characterizing Planets Around Other Stars.Measuring the Universe's Expansion Rate.Hubble has also studied the atmospheres of planets revolving around stars similar to Earth’s Sun. And it has revealed details of gamma-ray bursts - powerful explosions of energy that occur when massive stars collapse. The telescope has played a key role in the discovery of dark energy, a mysterious force that causes the universe to expand faster and faster as time goes on. Hubble has detected black holes, which suck in everything around them, including light. An image called the "Hubble Ultra Deep Field" shows the farthest galaxies ever seen. Hubble has helped scientists understand how planets and galaxies form. Scientists believe the universe is almost 14 billion years old. Images taken by Hubble have helped scientists estimate the age and size of the universe. What Is NASA Learning From the Hubble Space Telescope? Hubble Papers, Huntington Library, San Marino, California This led to the “Big Bang” theory, which says that the universe began with an intense burst of energy and has been expanding ever since.Įdwin Hubble seated at the 100-inch reflecting telescope at the Mount Wilson Observatory in California. His work helped show that the universe is expanding. He showed that the galaxy containing the solar system – the Milky Way – was only one of many galaxies. He made important discoveries in the early 1900s. ![]() Hubble is named after an American astronomer, Edwin P. Then Hubble uses radio waves to send the pictures back to Earth. Hubble is not the kind of telescope that you look through with your eye. So, Hubble can see space better than telescopes on Earth can. Hubble flies around, or orbits, high above Earth and its atmosphere. Earth's atmosphere changes and blocks some of the light that comes from space. The mixture of gases that surround a planet is called its atmosphere. What Makes Hubble Different From Telescopes on Earth? Jones (University of California – Santa Cruz) NASA’s Hubble Telescope captured this image that will leave you starry-eyed! Against an inky black backdrop, the blue swirls of spiral galaxy NGC 6956 stand out radiantly.
