Feast your eyes on 10 years of Hubble images of Jupiter, Saturn, Uranus, Neptune

While the Hubble Space Telescope might be most famous for its images of beautiful and far-off objects like nebulae or distant galaxies, it also takes images of objects closer to home, including the planets right here in our own solar system. For the past 10 years, Hubble has been studying the outer planets in a project called OPAL (Outer Planet Atmospheres Legacy), capturing regular images of each of the four outer planets so scientists can study their changes over time.

The planets Jupiter, Saturn, Uranus, and Neptune are different in many ways from Earth, as they are gas giants and ice giants rather than rocky planets. But they do have some similar phenomena, such as weather that regularly changes, including epic events like storms that are so large they can be seen from space. Jupiter’s Great Red Spot, for example, the big orange-red eye shape that is visible on most images of the planet, is an enormous storm larger than the width of the entire Earth and which has been raging for centuries.

In Hubble’s images of Jupiter collected between 2015 and 2024, you can see how the spot moves and changes over time, with the bands of color created by bands of atmosphere moving and changing as well:

As for the other planets, data from OPAL has revealed information about Saturn’s “spokes,” which are dark patches in the planet’s rings that appear in a seasonal pattern and disappear again after just a few rotations. Uranus also has epic storms that are due to its unusual rotation, as the planet is tilted so far over that it rotates almost on its side. Part of one of its hemispheres can go without seeing any direct sunlight for periods of up to 42 years, which affects the way that polar ice caps form and melt.

And as for Neptune, the most distant planet in the solar system, it has its own strange dark spot. The peculiar thing about this spot is that it seems to be transitory, as sometimes it appeared in images and sometimes not. It turns out that it was not one single spot, but multiple spots that formed and faded over time, and which were also created by storms. Hubble was able to watch one of these storms appearing and fading, as well as track it moving toward the equator over time. It also showed that the cloudy weather there is influenced by the sun — even though Neptune receives just 0.1% of the intensity of sunlight we get here on Earth.

James Webb takes rare direct image of a nearby super-Jupiter
Artist’s impression of a cold gas giant orbiting a red dwarf. Only a point of light is visible on the JWST/MIRI images. Nevertheless, the initial analysis suggests the presence of a gaseous planet that may have properties similar to Jupiter.

Even with huge ground-based observatories and the latest technology in space-based telescopes, it's still relatively rare for astronomers to take an image of an exoplanet. Planets outside our solar system are so far away and so small and dim compared to the stars they orbit that it's extremely difficult to study them directly. That's why most observations of exoplanets are made by studying their host stars. Now, though, the James Webb Space Telescope has directly imaged a gas giant -- and it's one of the coldest exoplanets observed so far.

The planet, named Epsilon Indi Ab, is located 12 light-years away and has an estimated temperature of just 35 degrees Fahrenheit (2 degrees Celsius). The fact it is so cool compared to most exoplanets meant that Webb's sensitive instruments were needed to study it.

Hubble finds mysterious and elusive black hole
An international team of astronomers has used more than 500 images from the NASA/ESA Hubble Space Telescope spanning two decades to detect seven fast-moving stars in the innermost region of Omega Centauri, the largest and brightest globular cluster in the sky. These stars provide compelling new evidence for the presence of an intermediate-mass black hole.

There's something strange about black holes. Astronomers often find small black holes, which are between five times and 100 times the mass of the sun. And they often find huge supermassive black holes, which are hundreds of thousands of times the mass of the sun or even larger. But they almost never find black holes in between those two sizes.

Hubble takes first image since switching to new pointing mode

The Hubble Space Telescope has been through some troubles of late, and the way that it operates had to be changed recently to compensate for some degraded hardware. The telescope's three gyros, which help it to switch between different targets in the sky, have been experiencing issues, with one in particular frequently failing over recent months. NASA made the decision recently to change the way that Hubble points, and it now uses just one gyro at a time instead of all three in order to preserve the two remaining gyros for as long as possible.
